Radiation sensitive material suitable for the production of radiation sensitive plates for lithographic printing plate manufacture is based on a polymer including a plurality of structural units represented by the formula:
in which, R represents H or CH₃; each R₁, which may be the same or different represents H or alkyl; R₂ represents a single bond or a substituted or unsubstituted divalent radical; Ar represents a substituted or unsubstituted divalent radical derived from an aromatic or heteroaromatic compound; X represents O, S or NH; A represents an anion; Y represents a carbonyl oxy or aromatic radical; and n is an integer equal to or greater than 1.
适用于平版印刷板制造的辐射敏感板生产的辐射敏感材料基于一种聚合物,该聚合物包括由式表示的多个结构单元:其中,R 代表 H 或 CH₃;每个 R₁,可以相同或不同地代表 H 或烷基;R₂代表单键或取代或未取代的二价基;Ar 代表从芳香族或杂芳香族化合物衍生的取代或未取代的二价基;X 代表 O、S 或 NH;A 代表阴离子;Y 代表羰基氧基或芳香族基;以及 n 是等于或大于 1 的整数。
