Abstract
Abstract A photopolymerizable composition for image formation, which comprises 30 - 95 wt. % of an unsaturated polyester having an acid value of 5 - 100 which is the condensation product of a carboxylic acid component containing more than 40 mole % of a carboxylic acid compound having the formula [I] <IMAGE> wherein R1 represents hydrogen or a C1-4 lower alkyl with a polyol component containing more than 30 mole % of a polyol having the formula [II] HO(R2O)nH wherein R2 represents C2-4 alkylene or a derivative thereof and n is an integer of 2 - 5 and 70 - 5 wt. % of a photopolymerizable unsaturated monomer and a photosensitizer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A photopolymerizable composition for image formation, which comprises: 30 - 95 wt. % of an unsaturated polyester having an acid value of 5 - 100 which is the condensation product of a carboxylic acid component containing more than 40 mole % of a carboxylic acid compound having the formula ##STR9## wherein R 1 represents hydrogen or a C 1-4 lower alkyl with a polyol component containing more than 30 mole % of a polyol having the formula ##STR10## wherein R 2 represents C 2-4 alkylene or a derivative thereof and n is an integer of 2 - 5; and 7- 5 wt. % of a photopolymerizable unsaturated monomer and a photosensitizer.
Claim 2
Dependent Claim
111 words
A photopolymerizable composition for image formation, which comprises: 30 - 95 wt. % of an unsaturated polyester having an acid value of 5 - 100 which is the condensation product of a carboxylic acid component containing more than 40 mole % of a carboxylic acid compound having the formula ##STR9## wherein R 1 represents hydrogen or a C 1-4 lower alkyl with a polyol component containing more than 30 mole % of a polyol having the formula ##STR10## wherein R 2 represents C 2-4 alkylene or a derivative thereof and n is an integer of 2 - 5; and 7- 5 wt. % of a photopolymerizable unsaturated monomer and a photosensitizer.
Claim 3
Dependent Claim
23 words
The photopolymerizable composition of claim 1, wherein said condensation product is modified by the incorporation of a polycarboxylic acid or an anhydride thereof.
Claim 4
Dependent Claim
83 words
The photopolymerizable composition of claim 1, wherein said unsaturated polyester having an acid value of 5 - 100 is produced by polycondensing a carboxylic acid component containing more than 40 mole % of said carboxylic acid compound of formula [I] with a polyol component containing more than 30 mole % of said polyol of formula [II] to obtain an unsaturated polyester having a hydroxyl value of 5 - 200 and then reacting a polycarboxylic acid or an anhydride thereof with said unsaturated polyester.
Claim 5
Dependent Claim
49 words
The photopolymerizable composition of claim 1, wherein said photopolymerizable unsaturated monomer is a combination of 5 - 95 wt. % of at least one monomer selected from the group consisting of acrylic acid, methacrylic acid and hydroxyesters thereof, and 95 - 5 wt.% of a second photopolymerizable unsaturated monomer.
Claim 6
Dependent Claim
24 words
The photopolymerizable composition of claim 4, wherein said second photopolymerizable unsaturated monomer is a photopolymerizable monomer containing more than two acryloyloxy or methacryloyloxy groups.
Claim 7
Dependent Claim
45 words
The photopolymerizable composition of claim 1, wherein said photopolymerizable unsaturated monomer is a mixture of monomers containing more than 30 wt. % of a compound having the formula ##STR11## wherein R 3 represents hydrogen, methyl, ethyl or methylol and R 4 represents hydrogen or methyl.
