Abstract
Abstract A low gloss radiation cure is obtained by applying an aqueous emulsion of relatively viscous radiation curable resin and curing the applied film with appropriate radiation energy before the emulsion in the applied film breaks, to produce a cured film containing microscopic discontinuities.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
50 words
A method of obtaining a low gloss radiation-cured coating comprising applying an aqueous emulsion coating composition to a substrate, said emulsion being constituted by water having emulsified therein viscous droplets comprising radiation curable resin, and subjecting said applied emulsion to radiation energy to cure the same before the emulsion breaks.
Claim 2
Independent Claim
50 words
A method of obtaining a low gloss radiation-cured coating comprising applying an aqueous emulsion coating composition to a substrate, said emulsion being constituted by water having emulsified therein viscous droplets comprising radiation curable resin, and subjecting said applied emulsion to radiation energy to cure the same before the emulsion breaks.
Claim 3
Dependent Claim
28 words
A method as recited in claim 1 in which said resin is ethylenically unsaturated tertiary amine reacted with a solubilizing acid, and said radiation energy is ultraviolet light.
Claim 4
Dependent Claim
22 words
A method as recited in claim 1 in which said emulsion as a resin solids content of at least 40% by weight.
Claim 5
Dependent Claim
32 words
A method as recited in claim 2 in which said ethylenically unsaturated tertiary amine reacted with a solubilizing acid in the absence of water has a viscosity of at least 200 centipoise.
Claim 6
Dependent Claim
31 words
A method as recited in claim 1 in which said ethylenically unsaturated tertiary amine reacted with a solubilizing acid in the absence of water has a viscosity of from 6-1000 poise.
Claim 7
Dependent Claim
35 words
A method as recited in claim 1 in which an ultraviolet photosensitizer is incorporated in said emulsion to render the same curable with ultraviolet light and ultraviolet light exposure is used to cure the coating.
Claim 8
Dependent Claim
18 words
A method as recited in claim 1 in which an ultraviolet photosensitizer is incorporated in said viscous droplets.
Claim 9
Dependent Claim
17 words
A method as recited in claim 1 in which said ethylenically unsaturated tertiary amine is a polyacrylate.
Claim 10
Dependent Claim
20 words
A method as recited in claim 1 in which said emulsion has a pH in the range of pH 4.0-8.5.
Claim 11
Dependent Claim
33 words
A method as recited in claim 1 in which said ethylenically unsaturated tertiary amine is a polyethylenically unsaturated organic compound Michael adducted with 0.2-1.2 equivalents of amine per mol of said organic compound.
Claim 12
Dependent Claim
20 words
A method as recited in claim 10 in which the ethylenically unsaturated organic compound is reacted with a monosecondary amine.
Claim 13
Dependent Claim
20 words
A method as recited in claim 11 in which the monosecondary amine is selected from diethyl amine and dibutyl amine.
Claim 14
Dependent Claim
22 words
A method as recited in claim 12 in which said ethylenically unsaturated tertiary amine has a viscosity in excess of 500 centipoise.
Claim 15
Dependent Claim
19 words
A method as recited in claim 1 in which the solubilizing acid is selected from acetic and glycolic acids.
Claim 16
Dependent Claim
18 words
A method as recited in claim 1 in which flatting pigment is added to further reduce the gloss.
Claim 17
Independent Claim
70 words
A method of obtaining a low gloss radiation-cured coating comprising applying an aqueous emulsion coating composition to a substrate, said emulsion having a resin solids content of at least 40% by weight and comprising water and radiation curable resin, and subjecting said applied emulsion to radiation energy to cure the samme before the emulsion breaks whereby complete coalescence of said emulsion is prevented to lower the gloss which is obtained.
Claim 18
Independent Claim
70 words
A method of obtaining a low gloss radiation-cured coating comprising applying an aqueous emulsion coating composition to a substrate, said emulsion having a resin solids content of at least 40% by weight and comprising water and radiation curable resin, and subjecting said applied emulsion to radiation energy to cure the samme before the emulsion breaks whereby complete coalescence of said emulsion is prevented to lower the gloss which is obtained.
Claim 19
Dependent Claim
27 words
A method as recited in claim 16 in which an ultraviolet photosensitizer is present in said emulsion, and ultraviolet light exposure is used to cure the coating.
Claim 20
Dependent Claim
20 words
A method as recited in claim 17 in which said emulsion contains from about 5 to about 40% of water.
Claim 21
Dependent Claim
24 words
A method as recited in claim 17 in which said emulsion is an oil-in-water emulsion containing from about 20 to about 30% of water.
Claim 22
Dependent Claim
24 words
A method as recited in claim 19 in which said radiation curable resin comprises a polyacrylate having a viscosity of at least 500 centipoise.
Claim 23
Dependent Claim
24 words
A method as recited in claim 20 in which said polyacrylate is emulsified in the water by means of an ethylenically unsaturated tertiary amine.
Claim 24
Dependent Claim
36 words
A method as recited in claim 18 in which said radiation curable resin comprises a polyacrylate having a viscosity of at least 500 centipoise, and said emulsion is stabilized by the presence of a nonionic surfactant.
