Surface-treating paint for shaped plastic articles

A surface-coating composition for plastic articles, which comprises as a film-forming agent (A) a mixture of the reaction of an aminoalkylalkoxy silane of the general formula ##STR1## WHEREIN R.sup.1 represents a divalent hydrocarbon group containing 1 to 4 carbon atoms, R.sup.2 and R.sup.3 represent a monovalent hydrocarbon group containing 1 to 4 carbon atoms, Z represents a hydrogen atom or an aminoalkyl group, and n is 0 or 1, with an epoxyalkylalkoxy silane of the general formula ##STR2## WHEREIN R.sup.1, R.sup.2 and R.sup.3 are as defined above, Q represents a glycidoxy group ##STR3## or an epoxycyclohexyl group, and m is 0 or 1, and (B) a mixture of an alkyl-modified methylol melamine of the general formula ##STR4## wherein R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8 and R.sup.9 represent a hydrogen atom or a monovalent hydrocarbon group with 1 to 4 carbon atoms, and an alkyd resin; the amount of component (A) being 45 to 80% by weight, and the amount of component (B) being 20 to 55% by weight, both based on the total amount of components (A) and (B). The composition may further contain (C) an acrylic acid derivative of the general formula ##STR5## wherein R.sup.10 represents a hydrogen atom or a methyl group, and R.sup.11 represents a hydrogen atom, a hydrocarbon group containing 1 to 4 carbon atoms, a hydroxyalkyl group or a glycidyl group, or its polymer of a low degree of polymerization, the amount of component (C) being 5 to 30% by weight based on the total amount of components (A), (B) and (C).

Surface-treating coating composition for plastic articles

A polyfunctional organic compound, as a crosslinking agent, is used for producing a branched polycarbonate or poly(ester-carbonate).

Impact-resistant, flame-retardant resin composition

A flame retardant resin composition having a high impact resistance is disclosed, containing (A) 20 to 85 weight percent of a high molecular weight aromatic polycarbonate copolymer comprising (1) 2 to 30 molar percent of a bisphenol the nucleus of which is substituted with a halogen and (2) 70 to 98 molar percent of a halogen-free bisphenol and (B) 80 to 15 weight percent of an ABS resin comprising a mixture of (1) a graft copolymer of a butadiene-based rubbery polymer to which is grafted a vinyl aromatic hydrocarbon and acrylonitrile and and (2) a copolymer of a vinyl aromatic hydrocarbon and acrylonitrile. The amount of said rubbery polymer is 5 to 40 weight percent of the ABS resin.
