Claim 1
Independent Claim
82 words
An ultraviolet-curable liquid coating composition exhibiting improved adhesion to metal and plastic surfaces comprising, in admixture; (1) from 10% to 60% of the mixture of an organic solvent- soluble solution copolymer of monoethylenically unsaturated monomers free of amine functionality and including from 5% to 20% of an amide of a monoethylenically unsaturated monocarboxylic acid; and (2) from 40% to 90% of the mixture of radiation-curable ethylenically unsaturated liquid, said coating composition including photoinitiators and/or photosensitizers rendering the composition sensitive to ultraviolet light.
Claim 2
Dependent Claim
82 words
An ultraviolet-curable liquid coating composition exhibiting improved adhesion to metal and plastic surfaces comprising, in admixture; (1) from 10% to 60% of the mixture of an organic solvent- soluble solution copolymer of monoethylenically unsaturated monomers free of amine functionality and including from 5% to 20% of an amide of a monoethylenically unsaturated monocarboxylic acid; and (2) from 40% to 90% of the mixture of radiation-curable ethylenically unsaturated liquid, said coating composition including photoinitiators and/or photosensitizers rendering the composition sensitive to ultraviolet light.
Claim 3
Dependent Claim
36 words
A coating composition as recited in claim 1 in which said ethylenically unsaturated liquid includes polyethylenically unsaturated material and the named components are present in solution in at least about 10% of inert volatile organic solvent.
Claim 4
Dependent Claim
46 words
A coating composition as recited in claim 2 in which said solution contains from 25% to 50% of said solvent which contains at least 30% of a c 1 to C 4 alkanol. said copolymer includes from 0.5% to 10% of copolymerized monoethylenically unsaturated carboxylic acid.
Claim 5
Dependent Claim
20 words
A coating composition as recited in claim 2 in which said amide is an amide of acrylic or methacrylic acid.
Claim 6
Dependent Claim
45 words

Claim 7
Dependent Claim
32 words
A coating composition as recited in claim 4 in which said composition further includes from 2% to 20% of a polyepoxide having a molecular weight of from about 500 to about 5,000.
Claim 8
Dependent Claim
25 words
A coating composition as recited in claim 2 in which said components (1) and (2) are present in a weight ratio of 40:60 to 60:40.
Claim 9
Dependent Claim
18 words
A coating composition as recited in claim 1 in which said polyethylenically unsaturated liquid is an hydroxy-functional polyacrylate.
Claim 10
Dependent Claim
43 words
- 9. A coating composition as recited in claim 1 in which said coating composition includes from 3% to 30% of the weight of said mixture of ethylenically unsaturated liquid selected from the group consisting of triallyl cyanurate, N-vinyl pyrrolidone and dimethyl acrylamide.
Claim 11
Dependent Claim
22 words
A coating composition as recited in claim 1 in which said composition is rendered sensitive to ultraviolet light using a ketonic photoinitiator.
