Claims
- 1. A photopolymerizable composition comprising at least one photopolymerizable ethylenically unsaturated compound containing a benzoin ether in an amount sufficient to initiate photopolymerization and a stabilizing amount of an epoxide having the formula: ##STR9## wherein: R.sup.5 is hydrogen or alkyl of 1 to 4 carbon atoms;
- X is oxygen, ##STR10## where y is an integer from 1 to 4, m being 2; or ##STR11## m being 1; and n is zero or 1.
- 2. The composition of claim 1 wherein said benzoin ether is present in said composition at a concentration of about 0.01 to about 30 percent by weight, and said epoxide is present at a concentration of about 0.01 to about 20 percent by weight of said benzoin ether.
- 3. The composition of claim 1 wherein in said formula, R.sup.5 is hydrogen or methyl; X is oxygen, ##STR12##
- 4. The composition of claim 1 wherein the ethylenically unsaturated compounds consist essentially of derivatives of acrylic acid.
