    • Positive-working imageable elements comprise a radiation absorbing compound and inner and outer layers on a substrate having a hydrophilic surface. The inner layer comprises a specific polymeric binder represented by Structure (I): (A)w-(B)n-(C)y-(D)z  (I) wherein A represents recurring units derived from one or more N-alkoxymethyl (alkyl)acrylamides or alkoxymethyl (alkyl)acrylates, B represents recurring units derived from one or more ethylenically unsaturated polymerizable monomers having a pendant cyano group, C represents recurring units derived from one or more ethylenically unsaturated polymerizable monomers having one or more carboxy, sulfonic acid, or phosphate groups, D represents recurring units derived from one or more ethylenically unsaturated polymerizable monomers other than those represented by A, B, and C, w is from about 3 to about 80 weight %, x is from about 10 to about 85 weight %, y is from about 2 to about 80 weight %, and z is from about 10 to about 85 weight %. The use of this polymeric binder provides improved post-development bakeability chemical solvent resistance and desired digital speed.
    • 正性可成像元件包括辐射吸收化合物和在具有亲水表面的基底上的内层和外层。 内层包含由结构(I)表示的特定聚合物粘合剂:<?in-line-formula description =“In-line Formulas”end =“lead”→>(A)w-(B)n-(C) 其中A表示由一个或多个N-烷氧基甲基(烷基)丙烯酰胺或烷氧基甲基(烷基)丙烯酰胺衍生的重复单元,其中A表示由一个或多个N-烷氧基甲基(烷基)丙烯酰胺或烷氧基甲基 (烷基)丙烯酸酯,B表示衍生自具有侧基氰基的一种或多种烯属不饱和可聚合单体的重复单元,C表示衍生自一种或多种具有一个或多个羧基,磺酸或磷酸基团的烯属不饱和可聚合单体的重复单元, D代表由除A,B和C之外的一种或多种烯属不饱和可聚合单体衍生的重复单元,w为约3-约80重量%,x为约10-约85重量%,y为 约2至约80重量%,z为约10至约85重量%。 使用该聚合物粘合剂提供改进的显影后烘烤性耐化学溶剂性和所需的数字速度。
