  • Thermoplastic elastomer and photosensitive resin composition based thereon, and printing plate precursor comprising the composition
    Patent number: 5053316
    Abstract: (I) 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 anhydride 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 Chthd 2-C.sub.4 alkylene glycol and a polyamide-forming monomer, and(ii) an ethylenic unsaturated compound, and(iii) a photopolymerization initiator,(II) a photosensitive sheet for printing plate formation which comprises a resin layer formed of the above composition, and(III) the above defined thermoplastic elastomer.
