Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
A photopolymerizable compound comprising the product of the reaction of (1) a monomeric hydroxy-containing polyethylenically unsaturated ester or (an) a monomeric isocyanatemodified hydroxy-containing polyethylenically unsaturated ester which is the product of the reaction of (a) an ethylenically unsaturated acid and (b) a polyhydric alcohol and (2) a polycarboxy-substituted benzophenone acid or anhydride having the formula ##STR2## wherein m and n is each an integer from 0 to 3 and the sum of m plus n is in the range of 2 to 6; and X and Y is each 1 and 4 halogen atoms or dialkylamino groups having 1 to 4 carbon atoms; X and Y may be the same or different and either or both may be omitted (.), the benzophenone moiety being about 5-50 weight percent of the product.
Claim 2
Dependent Claim
131 words
A photopolymerizable compound comprising the product of the reaction of (1) a monomeric hydroxy-containing polyethylenically unsaturated ester or (an) a monomeric isocyanatemodified hydroxy-containing polyethylenically unsaturated ester which is the product of the reaction of (a) an ethylenically unsaturated acid and (b) a polyhydric alcohol and (2) a polycarboxy-substituted benzophenone acid or anhydride having the formula ##STR2## wherein m and n is each an integer from 0 to 3 and the sum of m plus n is in the range of 2 to 6; and X and Y is each 1 and 4 halogen atoms or dialkylamino groups having 1 to 4 carbon atoms; X and Y may be the same or different and either or both may be omitted (.), the benzophenone moiety being about 5-50 weight percent of the product.
Claim 3
Dependent Claim
23 words
The compound of claim 1 wherein the ester (1) is a di- or polyacrylate, a di- or polymethacrylate, or a di- or polyitaconate.
Claim 4
Dependent Claim
22 words
The compound of claim 1 wherein the ester (1) is an isocyanatemodified di- or polyarylate, di- or polymethacrylate, or di- or polyitaconate.
Claim 5
Dependent Claim
26 words
The compound of claim 1 wherein the polyhydric alcohol is pentaerythritol, the ethylenically unsaturated acid is acrylic acid, and the carboxy-substituted benzophenone is benzophenone tetracarboxylic dianhydride.
Claim 6
Dependent Claim
17 words
The compound of claim 1 wherein the benzophenone moiety is about 15-40 weight percent of the product.
Claim 7
Dependent Claim
13 words
A photopolymerizable printing ink comprising the compound of claim 1 and a colorant.
Claim 8
Dependent Claim
9 words
A photopolymerizable adhesive comprising the compound of claim 1.
Claim 9
Dependent Claim
11 words
A photopolymerizable coating composition consisting of the compound of claim 1.
