A photopolymerizable composition comprised of an addition polymerizable material, a photoinitiator, a thermal addition polymerization inhibitor and a polymeric binding agent. The addition polymerizable material is comprised of a defined monoethylenically unsaturated acrylate and one or more non-gaseous compounds having at least two terminal ethylenic groups. The photopolymerizable composition displays superior flexibility and develops and strips more efficiently when compared to a like composition but in the absence of the acrylate. The photopolymerizable composition may be in the form of sheet or roll on a film support which can be laminated to a substrate and can be used in the preparation of printed circuit boards.
一种由可加成聚合材料、光引发剂、热加成聚合抑制剂和聚合物结合剂组成的光聚合组合物。可加成聚合材料由确定的单乙烯不饱和丙烯酸酯和一种或多种至少具有两个末端乙烯基的非气体化合物组成。与不含丙烯酸酯的同类组合物相比,这种可光聚合组合物具有更好的柔韧性,显影和剥离效率更高。这种可光聚合的组合物可以片状或卷筒状出现在薄膜支架上,可以层压到基材上,并可用于制备印刷电路板。
