    Abstract: Disclosed are colored compositions useful for molding into articles such as food containers, beverage bottles, cured structural plastics and the like comprising condensation polymer having reacted therewith or copolymerized therein a coloring amount of the residue of a colorant compound having the formula; ##STR1## wherein R.sup.1 is ##STR2## carbonyl halide or an unsubstituted or substituted carbocyclic or hetrocyclic aryl radical;R.sup.2 is hydrogen or an unsubstituted or substituted alkyl or acyl radical;R.sup.3 is any of the substituents which R.sup.1 may represent; andA.sup.1 and A.sup.2 each is the residue of a fused benzene ring; whereinR.sup.4 is hydrogen, allyl or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical; andR.sup.5 is hydrogen or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical; provided the colorant compound bears at least one substituent that is reactive with one of the monomers from which the condensation polymer is derived.The colorant compound residues are present in the polymer chain and impart a red color to the polymer. The residues are nonextractable from the polymer and stable at the condition at which the polymers are prepared and processed.
