The invention relates to photopolymerizable compositions containing an oxonol dye, which compositions cure by exposure to ultraviolet and/or visible radiation and whose visible color is substantially reduced during exposure. More particularly, the invention pertains to photopolymerizable compositions comprising a pyridin-2,6-dione oxonol dye in an admixture of a polymerizable component and a photopolymerization initiator. Such compositions find use as adhesives, coatings, and the like. The disappearance of the visible color of the oxonol dye acts as an indicator of full cure of a photopolymerizable composition.
本发明涉及含有氧杂壬醇染料的可光聚合组合物,该组合物通过暴露于紫外线和/或可见辐射而固化,其可见颜色在暴露过程中大大减少。更具体地说,本发明涉及可光聚合的组合物,该组合物包含一种吡啶-2,6-二酮氧杂壬醇染料,与一种可聚合组分和一种光聚合引发剂混合。这种组合物可用作粘合剂、涂料等。羰基酚染料可见光颜色的消失可作为光聚合成分完全固化的指标。
