A universal method to make photosensitive polymers from poly(vinyl alcohol) and poly(vinyl pyridine) is disclosed which generally does not require final purification and can produce photosensitive polymers which are of similar photosensity whether prepared with a poly(vinyl alcohol) or poly(vinyl pyridine) backbone. These polymers comprise a heterocyclic, light-sensitive pendant group including a moiety having the formula: ##STR1## wherein Z.sup.1 denotes the atoms necessary to form a substituted or unsubstituted aromatic heterocyclic ring; Z.sup.2 denotes the atoms necessary to form a substituted or unsubstituted aromatic or aromatic heterocyclic ring; R is hydrogen or a substituted or unsubstituted alkyl group; M is a divalent organic moiety; Y is a residue from a grafting group that is capable of grafting the pendant group onto a polymeric backbone.
