Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
28 words
A photopolymerizable composition comprising at least one olefinically unsaturated monomer and a catalyst comprising an'acylphosphine oxide for use in treating teeth by its application to a prepared tooth.
Claim 2
Dependent Claim
28 words
A photopolymerizable composition comprising at least one olefinically unsaturated monomer and a catalyst comprising an'acylphosphine oxide for use in treating teeth by its application to a prepared tooth.
Claim 3
Dependent Claim
16 words
The composition of Claim 1, wherein the monomer includes at least one acrylic or methacrylic ester.
Claim 4
Dependent Claim
71 words
The composition of Claim 1 or Claim 2, wherein the catalyst comprises an acylphosphine oxide of the formula: wherein each R individually is a hydrocarbyl group, which can be halo, alkyl, or alkoxy substituted, and wherein R represents a hydrocarbyl group, an S,0, or N containing five - or six membered heterocyclic ring, or the group -Z-CO-P(0)-(R) 2 wherein R is as defined above, and Z represents a divalent hydrocarbyl group.
