    摘要: 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).
