Disclosed are thermally-stable, red, anthraquinone colorants which contain one or more ethylenically-unsaturated, photopolymerizable radicals and which may be copolymerized with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic polymers, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The compounds possess good stability to ultraviolet light, good solubility in vinyl monomers, good color strength and thermal stability. Also disclosed are acrylic polymeric materials, i.e., polymers derived from acrylic acid esters, methacrylic acid esters and/or other copolymerizable vinyl compounds, having copolymerized therein one or more of the colorant compounds of the present invention.
本发明公开了热稳定的红色蒽醌着色剂,该着色剂含有一个或多个乙烯不饱和、可光聚合的自由基,可与乙烯不饱和单体共聚,生产出有色组合物,如有色丙烯酸聚合物、有色聚苯乙烯以及由其他乙烯不饱和单体衍生的类似有色聚合物材料。这些化合物具有良好的紫外线稳定性、在乙烯基单体中的良好溶解性、良好的着色强度和热稳定性。同时公开的还有丙烯酸聚合物材料,即由丙烯酸酯、甲基丙烯酸酯和/或其它可共聚的乙烯基化合物衍生的聚合物,其中共聚了一种或多种本发明的着色剂化合物。
