    Abstract: Laminate consists of at least two bonded layers, the first layer contg. at least 30% wt. of a styrene polymer (I) with a good thermal stability, and the second layer contg. a styrene polymer other than polymer (I). Specif. the styrene polymer (I) consists of a copolymer of 95-50% wt. styrene and 5-50% wt. maleic anhydride, fumaric anhydride or itaconic anhydride, of 90-20% wt. styrene and 10-80% wt, alpha-methylstyrene, of 90-50% wt. styrene and 10-90% wt. methyl methacrylate of 90-50% wt. alpha-methylstyrene and 10-50% wt. acrylonitrile, or a terpolymer of styrene/alpha-methylstyrene/acrylonitrile, or styrene/methyl methacrylate/alpha-methylstyrene, or styrene/acrylonitrile/maleic anhydride, or styrene/methyl methacrylate/maleic anhydride. The laminates have a combination of lhigh thermal stability, and high rigidity, resistance to impacts, resistance to scratching and/or resistance to solvents, which cannot be obtained with the individual styrene polymers.

    Abstract: The film is coated with a paper-coating material consisting of 100 parts pigment with 20 to 100 parts of a binder, in which the binder is a co-polymer of an acrylic or methacrylic acid ester, an unsaturated carboxylic acid and, opt. other vinyl monomers. The coating is suitable for application to any of the usual styrene polymers, esp. polystyrene or styrene -acrylonitrile co-polymer modified with rubber for improved impact-resistance. Adhesion of the coating to the film is good and ageing is better than that of polybutadiene coatings, with less yellowing and embrittlement.
