Abstract
Abstract A resinous coating composition capable of forming a cured coating film in air when irradiated with high energy ionizing radiation is formed by the admixture of (1) a resin obtained by reacting (A) an hydroxyl-containing vinyl polymer or copolymer with (B) an ethylenically unsaturated isocyanate obtained by reacting 1.4 to 0.6 moles of an ester of an Alpha - Beta unsaturated monocarboxylic acid containing at least one hydroxyl group in the molecule with one mole of a diisocyanate wherein 1,000 gm. of (A) is reacted with 0.1 to 0.4 gram equivalence of (B), to form a vinyl polymer or copolymer containing ethylenically unsaturated side chains, and (2) a monomer copolymerizable with said ethylenically unsaturated bonds in said resin (1).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
12 words
a monomer copolymerizable with said ethylenically unsaturated bonds in said resin (1).
Claim 2
Dependent Claim
33 words
A resinous composition as defined in claim 1 in which the vinyl polymer or copolymer (A) containing hydroxyl groups in side chains is a polymer or copolymer of a hydroxyl group-containing unsaturated monomer.
Claim 3
Dependent Claim
24 words
admixing the product obtained from (1.) with an ethylenically unsaturated monomer which is copolymerizable with the unsaturated side chains of the product of (2.).
Claim 4
Dependent Claim
43 words
A resinous composition as defined in claim 1 in which the vinyl polymer or copolymer (A) containing hydroxyl groups in side chains is a copolymer of a hydroxyl group-containing unsaturated monomer and a monomer copolymerizable therewith which is free of any hydroxyl groups.
Claim 5
Dependent Claim
47 words
A resinous composition as defined in claim 1 in which the ester of an Alpha , Beta -unsaturated monocarboxylic acid is a member of the group consisting of esters of acrylic acid, methacrylic acid and crotonic acid, said ester containing at least one hydroxyl group per molecule.
Claim 6
Dependent Claim
10 words
A process for preparing a resinous coating composition which comprises:
Claim 7
Dependent Claim
41 words
The process of claim 5 wherein said admixture is subjected to the action of high energy ionizing radiation at a dose rate sufficient to copolymerize said ethylenically unsaturated monomer (2.) with said resinous product (1.) and thereby cross-link said resinous product.
Claim 8
Dependent Claim
23 words
The process of claim 5 wherein said hydroxy containing vinyl polymer is formed by polymerizing a hydroxyl group containing an ethylenically unsaturated monomer.
Claim 9
Dependent Claim
29 words
The process of claim 5 wherein said hydroxy containing vinyl polymer is formed by polymerization or copolymerization of a vinyl ester which is thereafter hydrolyzed to form hydroxyl groups.
Claim 10
Dependent Claim
21 words
The process of claim 5 wherein said hyDroxy containing vinyl polymer is formed by reacting a polyepoxide with a carboxylic acid.
Claim 11
Dependent Claim
24 words
The process of claim 5 wherein the reaction of (A) and (B) is conducted at a temperature of from 40* C. - 150* C.
