Methods of forming patterned coatings are disclosed. The methods include the steps of disposing a composition onto a substrate to form a liquid coating on the substrate and removing or providing energy through a first pattern of areas on the liquid coating to form a topographically patterned coating
Methods of forming patterned coatings are disclosed. The methods include the steps of disposing a composition onto a substrate to form a liquid coating on the substrate and removing or providing energy through a first pattern of areas on the liquid coating to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas.

1. A method of forming a topographically patterned coating comprising the steps of: a) disposing a composition comprising a polymer or polymer precursors onto a substrate selected from the group polymeric films, paper, polymer-coated paper, rubber and laminates of polymers, to form a liquid coating
1. A method of forming a topographically patterned coating comprising the steps of: a) disposing a composition comprising a polymer or polymer precursors onto a substrate selected from the group polymeric films, paper, polymer-coated paper, rubber and laminates of polymers, to form a liquid coating on the substrate;b) cooling the coating through the substrate by means of an energy transfer surface selected from a plate on the side of the substrate opposite the liquid coating and a roll over which the coated substrate is transported, the plate or roll having a first pattern of areas to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas; andc) solidifying the topographically patterned coating by polymerizing, cross-linking, curing, drying, or freezing the coating to yield topographical features having a mean height of 10 nanometers to 1 millimeter and a mean width of 10 nanometers or greater. 2. A method according to claim 1 further comprising providing energy through one side of the liquid coating from a source external to the coating simultaneously with removing energy through an opposite side. 3. A method according to claim 1 wherein the disposing step comprises disposing a composition comprising a polymer or polymer precursor and a liquid vehicle onto a substrate to form a liquid coating on the substrate. 4. A method according to claim 3 further comprising removing the liquid vehicle component from the coating. 5. A method according to claim 1 wherein the solidifying step comprises polymerizing, cross-linking, or curing the topographically patterned coating by exposing it to ultraviolet radiation. 6. A method of forming a topographically patterned coating comprising the steps of: a) disposing a composition comprising a polymer or polymer precursor onto a substrate selected from the group polymeric films, paper, polymer-coated paper, rubber and laminates of polymers, to form a liquid coating on the substrate;b) providing energy to the liquid coating from an energy source selected from an infrared source directing infrared energy through a first pattern of areas on a polymer film or metal plate or a laser beam chopped to create a first pattern of areas to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas, the coating being disposed between the substrate and the energy source; andc) solidifying the topographically patterned coating by polymerizing, cross-linking, curing, drying or freezing the coating to yield topographical features having a mean height of 10 nanometers to 1 millimeter and a mean width of 10 nanometers or greater. 7. A method according to claim 6 further in which the step of solidifying the topographically patterned coating comprises exposing it to ultraviolet radiation. 8. A method according to claim 6 wherein the disposing step comprises disposing a composition comprising a polymer or polymer precursor and a liquid vehicle onto a substrate to form a liquid coating on the substrate. 9. A method according to claim 8 further comprising removing the liquid vehicle component from the coating. 10. A method of forming a topographically patterned coating comprising the steps of: a) disposing a composition onto a substrate selected from the group polymeric films, paper, polymer-coated paper, rubber and laminates of polymers to form a liquid coating on the substrate;b) disposing the substrate on an energy transfer surface on a plate or a roll over which the substrate is transported;providing energy selected from the group consisting of infrared and heat energy from the energy transfer surface through a first pattern of areas on the energy transfer surface to form a topographically patterned coating; andc) solidifying the topographically patterned coating by polymerizing, cross-linking, curing, drying or freezing the coating, the topographical pattern corresponding to the first pattern of areas, the topographical features of the pattern having a mean height of 10 nanometers to 1 millimeter and a mean width of 10 nanometers or greater. 11. A method of forming a topographically patterned coating comprising the steps of: a) disposing a pressure sensitive adhesive forming composition onto a substrate selected from the group polymeric films, paper, polymer-coated paper, rubber and laminates of polymers, to form a liquid coating on the substrate;b) providing energy to the coating from an energy source selected from infrared energy directed through a first pattern of areas on a polymer film or metal plate or a laser beam chopped to create a first pattern of areas to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas; andc) solidifying the topographically patterned coating by polymerizing, cross-linking, curing, drying or freezing the coating, to yield topographical features having a mean height of 10 nanometers to 1 millimeter and a mean width of 10 nanometers or greater. 12. A method of forming a topographically patterned coating comprising the steps of: a) disposing a composition comprising a polymer or polymer precursor and nanoparticles onto a substrate selected from the group polymeric films, paper, polymer-coated paper, rubber and laminates of polymers, to form a liquid coating on the substrate;b) providing energy to the coating from an energy source selected from infrared energy directed through a first pattern of areas on a polymer film or metal plate or a laser beam chopped to create a first pattern of areas to form a topographically patterned coating, the topographical pattern corresponding to the first pattern of areas; andc) solidifying the topographically patterned coating by polymerizing, cross-linking, curing, drying or freezing the coating, to yield topographical features having a mean height of 10 nanometers to 1 millimeter and a mean width of 10 nanometers or greater.
