A light sensitive polymer, susceptible to crosslinking on exposure to actinic light. The polymer contains the recurring unit; R1R2 ¦¦ --C-C-- ¦¦ ¦R3 O=C ¦ O ¦ CH2 ¦ CH-R4 ¦ CH2-R5 R1, R2 and R3 are each selected from the group consisting of hydrogen, halogen and lower alkyl. At least one of R4 and R5 is an azidobenzoyloxy or azidonaphthoyloxy group. The other of R4 and R5 is selected from the group consisting of hydroxyl, halogen, alkoxy, aryloxy, aralkoxy, alkoxyalkoxy, aryloxyalkoxy, alkoxyaryloxy, aryloxyaryloxy, alkylacyloxy, arylacyloxy, alkenylacyloxy, aralkenylacyloxy, heterocyclic substituted alkenylacyloxy, azidobenzoyloxy and azidonaphthoyloxy.
