    • 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.
    • 公开了可用于模制成诸如食品容器,饮料瓶,固化的结构塑料等制品的着色组合物,其包含与其反应或与其共聚的具有下式的着色剂化合物的着色量的缩聚物; 或者其中R 1为羰基卤或未取代或取代的碳环或杂环芳基的“IMAGE”或“IMAGE” R2是氢或未取代或取代的烷基或酰基; R3是R1可以表示的任何取代基; A1和A2各自为稠合苯环的残基; 其中R4是氢,烯丙基或未取代或取代的烷基,环烷基或芳基; 并且R 5是氢或未取代或取代的烷基,环烷基或芳基; 只要着色剂化合物具有至少一个与衍生缩合聚合物的单体之一反应的取代基。 着色剂化合物残基存在于聚合物链中并赋予聚合物红色。 残余物不可聚合,并且在制备和加工聚合物的条件下是稳定的。
