Substrates, coatings and methods for marking substrates using the coatings. The substrate contains a coating of encapsulated marking materials. Capsules of the encapsulated marking materials are designed to preferentially absorb a predetermined wavelength of light or range of wavelengths of light. The capsules contain color chemistry capable of activation by the predetermined wavelength of light or range of wavelengths of light for the generation of a color response. By utilizing capsules of differing color chemistries, such substrates are capable of multi-color image generation.

What is claimed is: 1. An optical disc, comprising: a data surface for recording data; and a label surface opposite the data surface and having thereon a coating of encapsulated marking materials containing at least a plurality of first capsules, wherein the first capsules comprise at least one first radiation absorber to preferentially absorb at least one first predetermined wavelength of light and wherein the marking materials of the first capsules are capable of activation by the at least one first predetermined wavelength of light for the generation of a first color response on the label surface; wherein the coating further contains a plurality of second capsules, wherein the second capsules comprise at least one second radiation absorber to preferentially absorb at least one second predetermined wavelength of light different than the at least one first predetermined wavelength of light and wherein the marking materials of the second capsules are capable of activation by the at least one second predetermined wavelength of light for the generation of a second color response on the label surface; wherein the at least one first predetermined wavelength of light is a wavelength of light further capable of recording data in the data surface. 2. The optical disc of claim 1, wherein the first capsules are further designed to preferentially absorb a first range of wavelengths of light. 3. The optical disc of claim 1, wherein the optical disc is selected from the group consisting of CD-R, CD-RW, DVD-R, DVD+R, DVD-RAM, DVD-RW, DVD+RW and BLU-RAY discs. 4. The optical disc of claim 1, wherein the second capsules are further designed to preferentially absorb a second range of wavelengths of light. 5. The optical disc of claim 4, wherein the first capsules are further designed to preferentially absorb a first range of wavelengths of light and wherein at least a portion of the second range of wavelengths of light is mutually exclusive from a portion of the first range of wavelengths of light. 6. The optical disc of claim 1, wherein the coating further contains a plurality of third capsules, wherein the third capsules comprise at least one third radiation absorber to preferentially absorb at least one third predetermined wavelength of light different than the at least one first and the at least one second predetermined wavelengths of light and wherein the marking materials of the third capsules are capable of activation by the at least one third predetermined wavelength of light for the generation of a third color response. 7. The optical disc of claim 6, wherein the third capsules are further designed to preferentially absorb a third range of wavelengths of light. 8. The optical disc of claim 7, wherein the first capsules are further designed to preferentially absorb a first range of wavelengths of light, wherein the second capsules are further designed to preferentially absorb a second range of wavelengths of light, and wherein the first, second and third ranges of wavelengths of light each have at least a portion of their wavelengths that are mutually exclusive from a portion of each of the remaining ranges of wavelengths of light. 9. A computer-readable media, comprising: a label surface having a coating containing at least a plurality of first capsules and a plurality of second capsules; wherein the first capsules contain a first color chemistry for producing a first color response; wherein the first capsules contain a first radiation absorber; wherein the first color chemistry is capable of activation when a light source having a first wavelength associated with the first radiation absorber is directed at one or more of the first capsules; wherein the second capsules contain a second color chemistry for producing a second color response; wherein the second capsules contain a second radiation absorber; wherein the second color chemistry is capable of activation when a light source having a second wavelength associated with the second radiation absorber is directed at one or more of the second capsules; wherein the computer-readable media is a laser-recordable media; and wherein the light source includes a laser used for recording data onto the media. 10. The computer-readable media of claim 9, further comprising: wherein the coating further contains a plurality of third capsules, the third capsules containing a third color chemistry for producing a third color response; wherein the third capsules contain a third radiation absorber; and wherein the third color chemistry is capable of activation when a light source having a third wavelength associated with the third radiation absorber is directed at one or more of the third capsules. 11. The computer-readable media of claim 10, wherein the first, second and third color chemistries produce cyan, yellow and magenta color responses, respectively. 12. A method of generating an image on a computer-readable media, comprising: activating two or more encapsulated marking materials contained on a surface of the computer-readable media to generate two or more color responses on the surface using at least one means for data access of the computer-readable media; wherein the means for data access includes means for data access using more than one wavelength of laser light; wherein at least one wavelength of laser light of the means for data access is capable of recording data onto the computer-readable media; and wherein each of the two or more encapsulated marking materials is activated using a different wavelength of laser light of the means for data access. 13. A method of using a computer-readable media, comprising: placing the media in a data access device having a first surface facing a first light source; writing data to the media using the first light source; placing the media in the data access device having a second surface facing the first light source, wherein the second surface is opposite the first surface and wherein the second surface is coated with at least a plurality of first encapsulated marking materials and a plurality of second encapsulated marking materials; selectively irradiating a first portion of the second surface of the media using the first light source, causing capsules of the first encapsulated marking material in the irradiated first portion to change color, thereby generating a first color response; and with the second surface facing the first light source, selectively irradiating a second portion of the second surface of the media using a second light source, causing capsules of a second encapsulated marking material in the irradiated second portion to change color, thereby generating a second color response. 14. The method of claim 13, wherein the irradiated first portion and the irradiated second portion cover at least some of the same area of the second surface, thereby permitting mixing of the first and second color responses. 15. The method of claim 13, further comprising: with the second surface facing the first light source, selectively irradiating a third portion of the second surface of the media using a third light source, causing capsules of a third encapsulated marking material in the irradiated third portion to change color, thereby generating a third color response. 16. The method of claim 15, wherein the irradiated first portion, the irradiated second portion and the irradiated third portion cover at least some of the same area of the second surface, thereby permitting mixing of the first, second and third color responses. 17. The optical disk of claim 1, wherein at least one first radiation absorber is contained in wall material of the first capsules. 18. The optical disk of claim 1, wherein at least one first radiation absorber is contained in contents of the first capsules. 19. The optical disk of claim 1, wherein at least one second radiation absorber is contained in wall material of the second capsules. 20. The optical disk of claim 1, wherein at least one second radiation absorber is contained in contents of the second capsules.
