Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
36 words
The composition of claim 1, wherein said polymerizable compound is the reaction product of a polyisocyanate compound with a hydroxy compound containing an ethylenically unsaturated double bond and a tertiary amine compound containing a hydroxyl group.
Claim 2
Dependent Claim
40 words
The composition of claim 1, wherein said pOlymerizable compound is the reaction product of a polyisocyanate compound with a hydroxy compound containing an ethylenically unsaturated double bond, a tertiary amine compound containing a hydroxyl group and a saturated polyhydroxy compound.
Claim 3
Dependent Claim
34 words
The composition of claim 1, wherein said polymerizable compound is the reaction product of a polyisocyanate compound with a hydroxy compound containing an ethylenically unsaturated double bond and a primary or secondary amine compound.
Claim 4
Dependent Claim
38 words
The composition of claim 1, wherein said polymerizable compound is the reaction product of a polyisocyanate compound with a hydroxy compound containing an ethylenically unsaturated double bond, a primary or secondary amine compound and a saturated polyhydroxy compound.
Claim 5
Dependent Claim
42 words
The composition of claim 1, wherein said polymerizable compound is prepared by reacting the reaction product of an epoxy-group containing compound with a primary or secondary amine compound, with a polyisocyanate compound and a hydroxy compound containing an ethylenically unsaturated double bond.
Claim 6
Dependent Claim
105 words
A photo-polymerizable composition containing a polymerizable compound having an average molecular weight in the range of 144 -100,000, said polymerizable compound having 0.01 - 1.0 urethane linkage based on an average molecular weight of 100 with 0.001 -1.0 radical or linkage selected from the group consisting of a secondary amino radical, tertiary amino radical, urea linkage or mixture thereof based on an average molecular weight of 100 and 0.02 - 1.0 ethylenically unsaturated double bond based on an average molecular weight of 100; 0.001 - 10 % of a photopolymerization initiator based on the total weight of the photopolymerization composition; and an ethylenically unsaturated monomer.
