Abstract: PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having high and balanced transparency, chemical resistance and color stability. SOLUTION: The thermoplastic resin composition contains a rubber-containing graft copolymer dispersed in a vinyl copolymer. The ratio of the triple sequence of the acrylonitrile monomer unit existing in the acetone-soluble fraction of the thermoplastic resin composition is

Abstract: PROBLEM TO BE SOLVED: To obtain a rubber-containing styrenic thermoplastic resin composition that has well-balanced transparency, chemical resistance, color tone stability, and thermal stability on processing. SOLUTION: The objective resin composition is produced by formulating an anti-oxidizing agent to a rubber-reinforced styrenic resin that comprises a graft copolymer produced by polymerizing a vinyl monomer and an unsaturated carboxylic alkyl ester monomer in the presence of a rubber polymer and a vinyl copolymer obtained from vinyl monomer and an unsaturated carboxylic alkyl ester monomer in which the difference in refractive index between the rubber-reinforced styrenic resin and the anti-oxidizing agent is

Abstract: PROBLEM TO BE SOLVED: To obtain a light sensitive resin composition excellent in photocurable properties, and exhibiting homogeneous curability in the running direction of the light, and further to provide a method for producing the composition. SOLUTION: This light sensitive resin composition is obtained by reacting the carboxy group in an acrylic resin having a high light transmission, with an epoxy-containing acrylic unsaturated material, and having acrylic unsaturated bond. The light sensitive resin composition comprises the acrylic resin having the acrylic unsaturated double bond in the side chain, 5,000-200,000 weight average molecular weight, 3,000-50,000 number average molecular weight, 1.2-5.0 Mw/Mn and
