ABSTRACT:
Disclosed are (i) a positive-working photosensitive composition containing (a) a polymer having at least 60 mol % structural units represented by formula (1): ##STR1## wherein A represents a hydrogen atom, a halogen atom, or an alkyl group having 1 to 4 carbon atoms; X represents --CO-- or --SO.sub.2 --; Y represents --CO--R.sub.1 or --SO.sub.2 --R.sub.1, where R.sub.1 represents an alkyl group, a substituted alkyl group wherein the substituent on the substituted alkyl group is a halogen atom, an aryl group, an amido group, an alkoxy group or an alkoxycarbonyl group, an unsubstituted aromatic group, or a substituted aromatic group wherein the substituent on the substituted aromatic group is a halogen atom, an alkyl group, an alkoxy group having 1 to 10 carbon atoms, an amido group or an aryl group, provided that at least one of X and Y contains --SO.sub.2 --and (b) a o-naphthoquinone diazide, and (ii) a process for image formation which comprises image-wise exposing to light a photosensitive material having a photosensitive layer comprising the positive-working photosensitive composition and then developing the resulting photosensitive material with an aqueous alkali solution having a pH of 12.5 or below.
