PURPOSE:To obtain a photosensitive resin for use in a screen printing plate or textile printing plate developable only with water, superior in resolution, and in balance between flexibility and toughness, by using a specified modified copolymer. CONSTITUTION:A photosensitive resin for use in a photographic process is obtained by modifying with a Lewis acid capable of providing a proton and a polymerizable vinyl monomer contg. an epoxy group, a copolymer of (A) a polymerizable vinyl monomer having a tertiary nitrogen atom with its lone pair of electrons not conjugated, such as dimethylaminomethylstyrene, vinylpyridine, or N,N-dimethylaminoethyl(meth)acrylate, and (B) a polymerizable vinyl monomer represented by the shown general formula in which R<1>, R<2> are each H or methyl, R<3> is 1-8C alkyl or phenyl or 1-4C alkyl substd. phenyl, and n is 1-10. |
