Photopolymerizable compositions and associated elements and processes are disclosed herein that upon imaging afford improved sidewall geometry and development latitude. These compositions contain a polymeric binder having the formula:where A is a substituted or unsubstituted C4-C10 n-alkyl methacrylate, B is a substituted or unsubstituted C4-C10 n-alkyl acrylate, C is selected from the group consisting of methyl methacrylate and ethyl methacrylate, and D is selected from the group consisting of methacrylic acid and acrylic acid; andwhere w, x, y, and z are weight percentages of comonomers in the polymeric binder, w is 5 to 40%, x is 5 to 40%, y is 10 to 70%, and z is 10 to 30%.
