Polymeric acetal resins useful in lithographic printing are disclosed. The polymeric acetal resin contains units (A), (B), (C), (D), and (E). Unit (A) is a vinyl alcohol unit. Unit; (B) is a polyvinyl acetal unit containing an R group, where R is hydrogen, an aliphatic group, an aromatic group, or an arylaliphatic group. Unit (C) is a vinyl carboxylate unit. Unit (D) is an acidic vinyl acetal unit and/or a residue of an acidic vinyl monomer. Unit (E) is a free radical polymerization-inhibiting vinyl acetal unit and/or a free radical polymerization-inhibiting vinyl alcohol ester unit. The resin comprises about 10 to about 60 mol% of unit (A), about 5 to about 60 mol% of unit (B), about 0.3 to about 30 mol% of unit (C), about 1 to about 40 mol% of unit (D), and about 0.01 to about 2 mol% of unit (E).
本发明公开了用于平版印刷的聚合缩醛树脂。聚合缩醛树脂包含单元 (A)、(B)、(C)、(D) 和 (E)。单元(A)是乙烯醇单元。单元(B)是含有 R 基团的聚乙烯醇缩醛单元,其中 R 是氢、脂肪族基团、芳香族基团或芳基脂肪族基团。单元(C)是乙烯基羧酸酯单元。单元(D)是酸性乙烯基缩醛单元和/或酸性乙烯基单体的残余物。单元(E)是自由基聚合抑制乙缩醛单元和/或自由基聚合抑制乙烯醇酯单元。该树脂包括约 10 至约 60 摩尔%的单元(A)、约 5 至约 60 摩尔%的单元(B)、约 0.3 至约 30 摩尔%的单元(C)、约 1 至约 40 摩尔%的单元(D)和约 0.01 至约 2 摩尔%的单元(E)。
