| 摘要 |
A photosensitive resin composition comprising (i) a thermoplastic elastomer selected from (A) a poly(amide-imide) ester produced by reacting a polyamide-forming monomer with either an aromatic carboxylic acid or its anhydrided and either a polyalkylene glycol or an alpha , omega -dihydroxy hydrocarbon, (B) a poly(amide-imide) urethane produced by reacting the above poly(amide-imide) ester with a diisocyanate compound, and (C) a poly(amide-imide) urethane produced by reacting the above diisocyanate compound with a mixture of polymer diol and a poly(amide-imide) ester obtained from a C2-C4 alkylene glycol and a polyamide-forming monomer, and (ii) an ethylenic unsaturated compound, and (iii) a photopolymerization initiator, a photosensitive sheet for printing plate formation which comprises a resin layer formed of the above composition, and the above defined thermoplastic elastomer. |
