Abstract
Composition useful for molding into articles which as food containers, beverage bottles, cured structural plastics and the like comprising molding grade linear or unsaturated polyester or polycarbonate having reacted therewith or copolymerized therein the residue of one or more poly-methine compounds having the formula: ##STR1## wherein each R.sup.1 is independently selected from cyano, carboxy, alkenyloxycarbonyl, or a substituted or unsubstituted alkoxycarbonyl, cycloalkoxoycarbonyl or aryloxycarbonyl radical; PA0 each R.sup.2 is independently selected from one of the groups specified for R.sup.1 or an unsubstituted or substituted aryl, carbamoyl, alkanoyl, cycloalkanoyl, aroyl, alkylsulfonyl, cycloalkylsulfonyl, arylsulfonyl or aromatic, heterocyclic radical; PA0 each R.sup.3 is independently selected from hydrogen or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical; PA0 A.sup.1 and A.sup.2 are independently selected from 1,4-phenylene radicals; and PA0 L is an organic linking group bonded by non-oxo carbon atoms to the oxygen atoms adjacent to L; provided the poly-methine compound bears at least one substituent that is reactive with one of the monomers from whi…
