A photo album is provided having an ink-receptive coating on a surface of the photo album. A user may write text or draw pictures on the surface with an ink pen, such as with a gel-based ink pen. The ink-receptive coating protects the ink from smudging or smearing after the ink has dried. Consequently, the text and/or picture is durable. The writable or drawable surface may be the front or back exterior surface, and/or an interior surface.

A photo album as recited in claim 4, wherein the anionic monomers are selected from the group consisting of (meth)acrylic acid and acrylamido-2-methylpropane sulfonic acid. 8. A photo album as recited in claim 4, wherein the neutral monomers are selected from the group consisting of acrylamide, dialkylaminoalkyl (meth)acrylates, hydroxyalkyl (meth)acrylates, and N-vinyloxazolidone. 9. A photo album as recited in claim 1, wherein the amphoteric copolymer is formed from a plurality of monomers comprising about 60 to 80% dimethylaminoethyl methacrylate methyl chloride quaternary salt; acrylic acid and acrylamido-2-methylpropane sulfonic acid in a combined amount of about 10 to 20%; and about 10 to 20% hydroxyethylmethacrylate. 10. A photo album as recited in claim 1, wherein the nonionic polymer comprises a polyvinyl alcohol having a saponification level of about 85 to 95%. 11. A photo album as recited in claim 1, wherein the polyalkylene glycol or silicone surfactant comprises a polyethylene glycol having a weight-average molecular weight of at least 600. 12. A photo album as recited in claim 1, in which the gel ink-receptive coating further comprises a crosslinker. 13. A photo album as recited in claim 12, wherein the crosslinker is a dialdehyde. 14. A photo album as recited in claim 13, wherein the crosslinker is glyoxal. 15. A photo album as recited in claim 13, wherein the crosslinker is a polyethoxylated dialdehyde. 16. A photo album as recited in claim 1, wherein said ink-receptive coating further comprises a pigment. 17. A photo album as defined in claim 16, wherein said pigment comprises nano-sized particles. 18. A photo album as recited in claim 17, wherein the pigment comprises at least one of a colloidal silica and a colloidal alumina hydrate. 19. A photo album as recited in claim 1, wherein the nonionic copolymer comprises polyvinyl alcohol, the amphoteric copolymer comprises a copolymer of trialkylammonimumalkyl (meth)acrylate monomers, acrylic acid, acrylamido-2-methylpropane sulfonic acid, and hydroxyethyl methacrylate, and the polyalkylene glycol or silicone surfactant comprises polyethylene glycol. 20. A photo album as recited in claim 1, wherein the mixture comprises about 50 to 90% by weight nonionic polymer, about 10 to 50% amphoteric copolymer, and about 1 to 5% polyalkylene glycol or silicone surfactant. 21.
