  • Patent number: 9273204
    Abstract: An uncoated, highly reflective, impact-resistant injection-molded article which comprises a rubber ingredient (A) and a thermoplastic resin (B), characterized in that (1) the rubber ingredient (A) has been dispersed in the thermoplastic resin (B), (2) the rubber ingredient (A) has a coefficient of linear expansion of 12.5×10?5 to 19×10?5/° C., (3) the surface of the injection-molded article has a reflected-image clarity of 60-100%, and (4) the injection-molded article has a notched Charpy impact strength of 5-60 kJ/m2.

  • Patent number: 9187626
    Abstract: The present invention is an uncoated housing in which a molded product formed from a thermoplastic resin composition (D) containing 20-60% by mass of an acetone insoluble resin component (A), which contains a rubber component (a) with an average particle size of 0.05-0.3 ?m and has a coefficient of linear expansion of 11×10?5-20.5×10?5, 40-80% by mass of an acetone soluble resin component (B) (here, (A)+(B)=100% by mass), and a colorant (C), with (1) the acetone soluble resin component (B) containing 6.0-45% by mass of an unsaturated nitrile monomer derived component and (2) 2-20% by mass of a component with a molecular weight of 70,000 or less by gel permeation chromatography (GPC) measurements being contained in the acetone soluble resin component (B). On the basis of JIS K7105, the L* value for this uncoated housing is 13 or less, the luster 60-120%, and the haze value 30-90%.
