    • A photosensitive rubber printing plate having an excellent plate wear balance and a high ability to reproduce images, and a photosensitive elastomer composition for use in producing the plate. The composition is prepared by kneading a mixture of 65 parts by weight of a phosphated random copolymer (with a monomer composition of 60 % butadiene, 9 % methyl methacrylate, 20 % ethylene phosphate methacrylate, 10 % styrene, and 1 % divinylbenzene), 35 parts by weight of a polystyrene-polybutadiene-polystyrene block copolymer, 15 parts by weight of 1,7-heptanediol dimethacrylate, 1 part by weight of benzoin methyl ether, and 0.02 part by weight of methylhydroquinone. A 3 mm thick photosensitive rubber printing plate is produced by sandwiching the compositive between two polyester films and pressing the laminate on a press.

    • A material composition comprising (a) a polyfunctional isocyanate, (b) a compound having a molecular weight of 600 to 3,500 and two functional groups undergoing a polyaddition reaction with an isocyanate group, (c) a compound having a molecular weight of 500 or less and two functional groups undergoing a polyaddition reaction with an isocyanate group, and (d) a compound having a molecular weight of 700 or less and three functional groups undergoing a polyaddition reaction with an isocyanate group. A molded polymer article is produced by heating a mixture of component (a) with a part of component (b) to prepare a urethane prepolymer, and adding the rest of component (b) and components (c) and (d) to the prepolymer, followed by heating to effect a polyaddition reaction between component (a) and components (b), (c) and (d). The obtained article can be applied to the parts where a high degree of shrinkage is required, is lowly toxic, and has large tear strength, tensile strength and elongation and a small permanent set.

    • A molding with a hard-coating layer having an adhesion of at least 50 squares per 100 squares in the cross cut adhesion test, an adhesion of at least 40 squares per 100 squares even after being held in water at 70 DEG C for 1 hour, a haze value of 1.0 % or less in Taber's abrasion resistance test and a pencil hardness of 2H or above. The production process comprises either modifying the surface of a base material comprising a thermoplastic norbornene resin by, for example, corona discharge to give a surface tension of at least 50 dyn/cm or forming on the surface a primary primer layer comprising a copolymer composed of a vinylaromatic compound and a conjugated diene and modified by introducing a polar group thereinto, then forming a primer layer for a silicone-base hard-coating agent on the modified surface or the formed primary primer layer, and finally forming thereon a silicone-base hard-coating layer.
