Methods and apparatuses for roll coating are provided. The roll coating system () includes a coating roll () having a deformable inner layer () with a surface thereof covered by a deformable outer layer (), the inner layer being softer than the outer layer. A substrate () is conveyed to the nip () between the coating roll and a back-up roll (). A metered coating material is transferred from the coating roll to a patterned surface structure () of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.

An article () has a polyester film backing () and a primer layer () including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester film backing (). Another article includes a polyester backing (), a primer layer () including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester backing (), and a phenolic layer () disposed on the primer layer () on a surface opposite the polyester backing (). The phenolic layer () can include abrasive particles (). Processes for making the articles are also described, as well as methods for abrading a workpiece and improving adhesion between a polyester film backing () and a phenolic layer () on the polyester backing ().
