Abstract
Abstract A process for producing an aqueous emulsion type coating composition, which can form a film having excellent resistance to chemicals and water, which comprises irradiating the aqueous emulsion containing at least one radiation-crosslinkable resin and not containing substantial amounts of a stabilizer having a hydroxy group, such as cellulose and polyvinyl alcohol, by means of ionizing radiation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
A process for improving the properties of an aqueous emulsion type coating composition containing from 30% to 60% by weight of at least one radiation cross-linkable resin, selected from the group consisting of homo- or co-polymers of an acrylate, vinyl acetate, versatic acid, vinyl chloride and ethylene, wherein said coating composition contains less than 0.5% by weight of a stabilizer having hydroxy groups on the basis of weight of the composition and the composition is irradiated with ionizing radiation at a total dose in the range of from 10 4 rad to 10 8 rad before coating the composition on a substrate, said composition being and maintained in a stable emulsion state during and after irradiation.
Claim 2
Dependent Claim
116 words
A process for improving the properties of an aqueous emulsion type coating composition containing from 30% to 60% by weight of at least one radiation cross-linkable resin, selected from the group consisting of homo- or co-polymers of an acrylate, vinyl acetate, versatic acid, vinyl chloride and ethylene, wherein said coating composition contains less than 0.5% by weight of a stabilizer having hydroxy groups on the basis of weight of the composition and the composition is irradiated with ionizing radiation at a total dose in the range of from 10 4 rad to 10 8 rad before coating the composition on a substrate, said composition being and maintained in a stable emulsion state during and after irradiation.
Claim 3
Dependent Claim
27 words
The process defined in claim 1 wherein the resin is a radiation-crosslinkable copolymer of a methacrylate and at least one monomer capable of forming a radiation-crosslinkable resin.
Claim 4
Dependent Claim
16 words
The process defined in claim 1 wherein the ionizing radiation is electron beam or gamma rays.
