  • Patent number: 6420449
    Abstract: A resin composition comprises a thermoplastic resin, a non-terpene-series higher fatty acid or a derivative thereof and a black pigment. As the higher fatty acid or derivative thereof, use can be made of, for example, a saturated higher fatty acid having about 12 to 30 carbon atoms or a metal salt thereof. As the thermoplastic resin, use can be made of, for example, an acrylic resin A and a styrenic resin B. As the black dye or pigment, use can be made of, for example, carbon black. The resin composition may contain a dye or pigment such as titanium oxide. A clearly defined white marking is developed on the above resin composition by laser irradiation.

  • Patent number: 6045902
    Abstract: A tearable film having excellent tear properties contains a dispersed phase and a continuous phase, with said film formed from a composition containing a styrenic polymer, an olefinic polymer, and a compatibilizer wherein the compatibilizer is selected from the group consisting of hydrogenated or modified copolymer of styrene and conjugated diene, olefinic copolymer having a cyclic olefin unit, and chlorinated polyolefin. The film composition is subjected, without stretching, to T-die molding or inflation molding to provide a tearable film. In the continuous phase of the film, said dispersed phase having an average aspect ratio of 3 or more and/or a thickness of 1 .mu.m or less is dispersed in layers. The ratio of the continuous phase to the dispersed phase is 35-98:2-65 (% by weight). In the film, the tearing maximum torque is 60 g.multidot.cm/.mu.m or less and the tearing maximum tensile force is 10 g/.mu.m or less, and the film can be torn straightly at least in one direction.
