  A copolymer comprising (i) a plurality of ethylenic moieties A having a structure according to the following formula: wherein R2 and R3 independently represent hydrogen, a halogen or an optionally substituted linear, branched or cyclic alk(en)yl group, or an optionally substituted aromatic or heteroaromatic group, and (ii) a plurality of acetal moieties B having a structure according to the following formula: wherein L represents a divalent linking group; x = 0 or 1 and R1 represents an optionally substituted aromatic or heteroaromatic group including at least one hydroxyl group and optionally one or more additional substituent(s), and at least one electron withdrawing group in ortho or para position relative to the at least one hydroxyl group.

  一种共聚物，包含(i)多个具有下式结构的乙烯基分子 A： 其中 R2 和 R3 独立地代表氢、卤素或任选取代的直链、支链或环状烷（烯）基，或任选取代的芳香族或杂芳香族基团，以及 (ii) 具有下式结构的多个缩醛分子 B： 其中 L 代表二价连接基团；x = 0 或 1，R1 代表任选取代的芳香族或杂芳香族基团，包括至少一个羟基和任选一个或多个附加取代基，以及至少一个相对于至少一个羟基位于正位或对位的取电子基团。

  A copolymer comprising (i) a plurality of ethylenic moieties A having a structure according to the following formula (I): wherein R2 and R3 independently represent hydrogen, a halogen or an optionally substituted linear, branched or cyclic alk(en)yl group, or an optionally substituted aromatic or heteroaromatic, and (ii) a plurality of acetal moieties B having a structure according to the following formula (II): wherein L represents a divalent linking group; x = 0 or 1 and R1 represents an optionally substituted aromatic or heteroaromatic group including at least one hydroxyl group. Use of these polymers in the coating of lithographic printing plat provides a good abrasion resistance while the balance between the ink acceptance, arising from the ethylenic moieties, and the solubility in an alkaline developer, arising form the acetal moieties, can be controlled efficiently.
