Abstract
Abstract Ultraviolet-curable ethylenically unsaturated liquid coating composition are disclosed which consist essentially of: 1-polyethylenically unsaturated material in which the ethylenically unsaturated groups are polymerizable groups which are not (meth)acrylate groups; 2-a polyamine resin, preferably a polytertiary amine resin; and 3-an aryl ketone photosensitizer.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
35 words
An ultraviolet-curable ethylenically unsaturated liquid coating composition consisting essentially of: (1)--polyethylenically unsaturated material in which the ethylenically unsaturated groups are polymerizable groups which are not (meth)acrylate groups; (2)--a polyamine resin; and (3)--an aryl ketone photosensitizer.
Claim 2
Dependent Claim
35 words
An ultraviolet-curable ethylenically unsaturated liquid coating composition consisting essentially of: (1)--polyethylenically unsaturated material in which the ethylenically unsaturated groups are polymerizable groups which are not (meth)acrylate groups; (2)--a polyamine resin; and (3)--an aryl ketone photosensitizer.
Claim 3
Dependent Claim
30 words
An ultraviolet-curable coating composition as recited in claim 1 in which said components (1), (2) and (3) are in solution in a volatile inert organic solvent to provide coating viscosity.
Claim 4
Dependent Claim
19 words
An ultraviolet-curable coating composition as recited in claim 1 in which said polyamine resin is a polytertiary amine resin.
Claim 5
Dependent Claim
33 words
An ultraviolet-curable coating composition as recited in claim 1 in which said composition further includes a monoethylenically unsaturated liquid in which the ethylenically unsaturated groups are polymerizable groups which are not (meth)acrylate groups.
Claim 6
Dependent Claim
30 words
An ultraviolet-curable coating composition as recited in claim 1 in which said ethylenically unsaturated groups are selected from the group consisting of allyl, vinyl, styryl, maleate, fumarate, and mixtures thereof.
Claim 7
Dependent Claim
22 words
An ultraviolet-curable coating composition as recited in claim 1 in which said polyethylenically unsaturated material comprises a maleate or fumarate-containing polyester resin.
Claim 8
Dependent Claim
31 words
An ultraviolet-curable coating composition as recited in claim 3 in which said polytertiary amine-functional resin is a solvent-soluble copolymer containing from 5% to 50% by weight of a tertiary-amine-functional monoethylenic monomer.
Claim 9
Dependent Claim
29 words
An ultraviolet-curable coating composition as recited in claim 7 in which said amine-functional monoethylenic monomer is a dimethyl or diethylamino ethyl, propyl or butyl acrylate, methacrylate, acrylamide or methacrylamide.

Claim 16
Dependent Claim
39 words
An ultraviolet-curable coating composition as recited in claim 14 in which said single resin is an hydroxy-functional polytertiary amine resin which has been reacted via its hydroxy functionality with an ethylenically unsaturated monoisocyanate or an ethylenically unsaturated monocarboxylic acid.
Claim 17
Dependent Claim
20 words
An ultraviolet-curable coating composition as recited in claim 15 in which said hydroxy-functional polytertiary amine resin is an acrylic copolymer.
