    摘要： A colored styrenic resin composition comprises 100 parts by weight of a styrenic resin, 0.1 to 5 parts by weight of titanium oxide and 0.05 to 2.5 parts by weight of an organo-tin compound and in which the amount of the organo-tin compound is not less than 10% by weight on the basis of the amount of the titanium oxide. The resin composition ensures the production of injection-molded articles free of black streaks and, therefore, the articles formed from the resin composition of the invention have high commercial value. The colored styrenic resin composition is useful as a material for the production of housings of, for example, a variety of electric appliances and office machinery and equipment as well as miscellaneous goods.

    摘要： An easily recyclable container obtained by subjecting a sheet L which is a laminate of a plurality of layers, to vacuum forming and/or pressure forming, in which container the sheet L has such two adjacent layers as to give the minimum peeling strength and can be manually separated into two portions at the interface of the two adjacent layers, and when the portion of the sheet L present from the interface of said two adjacent layers to the inner surface of the container is named as film portion F and the portion of the sheet L present from said interface to the outer surface of the container is named as sheet portion S, the peeling strength required for peeling of the film portion F from the sheet portion S is set at 2 to 45 g/15 mm (width) by allowing said two adjacent layers giving the minimum peeling strength to be constituted by respective particular resins or resin compositions. This container has easy recyclability because, after the use, (1) the thin film constituting the inside surface of the container can be easily peeled by manual pulling of the tongue-shaped part of the film, (2) the left-overs in the container can be discarded by being wrapped by the film, (3) there is no need of washing the container, and (4) the main portion of the container can be easily recovered.
