18. An article comprising:
-
a) a substrate; and b) a textured, matte-finish, low adhesion backsize coating on one surface of the substrate, wherein the coating is formed from a composition comprising polyvinyl carbamate having nitrogen-bonded hydrocarbon side chains which provide terminal alkyl groups more than five carbons in length;
wherein the gloss of the backsize coating is less than that of the uncoated substrate and less than that of the substrate coated with the same coating composition that is not textured; and
further wherein the coating is formed from a composition comprising a solvent system comprising at least one good solvent for the polyvinyl carbamate and at least one poor solvent for the polyvinyl carbamate in a ratio sufficient to cause precipitation of the polymer upon evaporation of the solvent system. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

- 29. A method of preparing an article comprising a substrate on which is coated a textured, matte-finish, low adhesion backsize coating on one surface of the substrate, the method comprising coating a composition comprising polyvinyl carbamate having nitrogen-bonded hydrocarbon side chains which provide terminal alkyl groups more than five carbons in length and a solvent system comprising at least one good solvent for the polyvinyl carbamate and at least one poor solvent for the polyvinyl carbamate in a ratio sufficient to cause precipitation of the polymer upon evaporation of the solvent system.

42. A method of preparing an article comprising a substrate on which is coated a textured, matte-finish, low adhesion backsize coating on one surface of the substrate, the method comprising coating a composition comprising a low adhesion backsize polymer and a solvent system comprising a mixture of solvents in a ratio sufficient to cause precipitation of the polymer upon evaporation of the solvent system.

43. An article comprising:
-
a) a substrate; and b) a non-particle loaded, non-embossed, and non-mechanically roughened, textured, matte-finish, low adhesion backsize coating on one surface of the substrate, wherein the coating comprises polyvinyl carbamate having nitrogen-bonded hydrocarbon side chains which provide terminal alkyl groups more than five carbons in length.
