Abstract
Abstract Water reducible coating compositions based on a thermoplastic polymer prepared by polymerizing one or more ethylenically unsaturated monomers in the presence of a water soluble fully reacted polyurethane. The resulting polymer can be coated from solution as a clear film, heat cured, air dried or cross-linked. The coatings, when combined with pigments and metallics, are useful as automotive finishes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
34 words
A water reducible storage stable coating composition comprising a polymer of (a) about 2 to about 7 parts ethylenically unsaturated monomer, polymerized in the presence of (b) one part fully reacted water soluble polyurethane.
Claim 2
Dependent Claim
34 words
A water reducible storage stable coating composition comprising a polymer of (a) about 2 to about 7 parts ethylenically unsaturated monomer, polymerized in the presence of (b) one part fully reacted water soluble polyurethane.
Claim 3
Dependent Claim
18 words
The coating composition of claim 1 containing pigment in a pigment volume concentration of about 0.1 to 14%.
Claim 4
Dependent Claim
19 words
The coating composition of claim 1 in which the ethylenically unsaturated monomer is selected from acrylic and methacrylic monomers.
Claim 5
Dependent Claim
44 words

Claim 7
Dependent Claim
29 words
A water reducible storage stable coating composition comprising a polymer of (a) 3 parts acrylic monomer polymerized in the presence of (b) 1 part fully reacted water soluble polyurethane.
Claim 8
Dependent Claim
18 words
The coating composition of claim 5 containing pigment in a pigment volume concentration of about 0.1 to 14%.
Claim 9
Dependent Claim
19 words
The coating composition of claim 5 in which the acrylic monomer is selected from acrylic and methyl methacrylic monomers.
Claim 10
Dependent Claim
46 words
The coating composition of claim 5 wherein the polyurethane is formed from the reaction product of a diisocyanate component selected from the group consisting of isophorone diisocyanate, 1,6 hexamethylene diisocyanate, methylcyclohexylene diisocyanate and bis (4-isocyanateocyclohexyl) methane and a mixture of high and low molecular weight polyols.
