摘要:
A thermoplastic resin composition comprising:(a) Alkylene aryl polyester copolymers having metal sulfonate units represented by the formula IA: ##STR1## or the formula IB:(M.sup.+n O.sub.3 S).sub.d --A--(OR"OH).sub.pwhere p=1-3, d=1-3, p+d=2-6, n=1-5, and A is an aryl group containing one or more aromatic rings where the sulfonate substituent is directly attached to an aryl ring, R" is a divalent alkyl group and the metal sulfonate group is bound to the polyester through ester linkages;(b) An essentially amorphous polycarbonate, polyester carbonate or polyarylate polymer containing recurring units of the formula II: ##STR2## wherein Ar is divalent aromatic residue of a dicarboxylic acid or mixture of dicarboxylic acids and Ar' is the divalent aromatic residue of a dihydric phenol or mixture of dihydric phenols. The composition may further comprise acidic phosphorus based quenchers, rubbery impact modifiers, mineral fillers or reinforcements.

摘要:
A molded article suitable for direct application of a reflective metal coating includes an amorphous thermoplastic or thermoplastic blend having a glass transition temperature greater than about 170° C. and at least one thermally stable colorant that contributes to the article's dark appearance. The article has excellent dimensional stability, and the surface to which a metal coating can be applied exhibits low gloss. Application of a metal coating to the molded article produces a metalized surface with high total reflectivity, low diffuse reflectivity, and low haze. Compositions and methods for forming the article are described.
