An organic solvent- or water-developable photosensitive composition consisting essentially of a ring-opened polymer or copolymer of at least one norbornene derivative having at least one substituent selected from the group consisting of ester groups, nitrile groups, carboxyl groups, amide groups, imide groups, hydroxyl groups, halogens and carboxylic acid anhydride groups, or a ring-opened copolymer of at least one said norbornene derivative and at least one cycloolefin other than cyclohexene, or a hydrolysis product of said ring-opened polymer or copolymer and a photosensitive crosslinking agent or photosensitizer soluble in organic solvents or water. The above photosensitive composition is excellent in sensitivity, adhesion and stability.
A photosensitive composition consisting essentially of (1) a ring-opened polymer or copolymer of at least one norbornene derivative selected from the group consisting of methyl 5-norbornene-2-carboxylate, dimethyl 5-norbornene-2,3-dicarboxylate, N,N-dimethyl-5-norbornene-2-carboxylic acid amide, 5-norborne-2-nitrile and 5-norbornene-2,3-dicarboxylic anhydride, or a ring-opened copolymer of at least one said norbornene derivative and at least one cyclo-olefin selected from the group consisting of cyclopentene, cyclooctene and norbornene, wherein the molar ratio of the norbornene derivative to the cycloolefin in the ring-opened copolymer is from 100 :
A photosensitive composition consisting of (1) a ring-opened polymer of methyl 5-norbornene-2-carboxylate, wherein said ring-opened polymer has a structure comprising units of the general formula:
A water-developable photosensitive composition consisting essentially of (1) a hydrolysis product of a ring-opened polymer of methyl 5-norbornene-2-carboxylate, wherein said ring-opened polymer has a structure comprising units of the general formula:
