Photopolymers containing carboxyl groups as water soluble groups and o,m or p-nitro substituted benzalacetophenone(o-BAP . NO2, m-BAP . NO2, p-BAP . NO2) as sensitive groups are synthesized by condensing 4- (vinylbenzyloxy)acetophenoneco-methacrylic acid copolymer with o,m or p-nitro substituted benzaldehyde in alkaline catalyzer. These condensation polymer were effectively crosslinked by the irradiation of UV light. Alkaline aqueous developing solution available commercially for negative type presensitized plate can be applied for development of these photopolymers. Relative sensitivities of the condensation polymers in film stars were measured. It is found that order of sensitivity of the synthesized polymer are o-BAP . NO2〈m-BAP . NO2〈 p-BAP . NO2 The spectral sensitivities of p-BAP . NO2 were observed to be 0.03~0.05 mJ/㎠ at 300~400nm respectively
