Abstract
Abstract A water-dilutable maleinized oil base coating composition is prepared by mixing from about 10 to about 90% by weight water-dilutable maleinized oil with from about 90% to about 10% by weight of a solid particulate polyester which contains from 5 to 35% by weight of a halogen. One of the carboxylic acids used in making the solid particulate polyester contains a halogen. The percentages by weight of the coating composition are based on the total weight of the two components on a solvent free basis. The novel coating composition can be used to advantage for coating any substrate and particularly for coating automobile bodies.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
92 words
A water-dilutable maleinized oil based coating composition containing a binder made up of 10-90% by weight of the water-dilutable maleinized oil and 90-10% by weight of a solid particulate polyester which contains halogen-containing polycarboxylic acid in an amount whereby the solid particulate polyester contains a halogen in an amount equivalent to 5 to 35% by weight of chlorine, the percentages by weight of the two components being calculated on the sum of the solvent-free weights thereof, said maleinized oil containing from 10-40% by weight of residues from an α-β-ethylenically unsaturated dicarboxylic acid.
Claim 2
Dependent Claim
92 words
A water-dilutable maleinized oil based coating composition containing a binder made up of 10-90% by weight of the water-dilutable maleinized oil and 90-10% by weight of a solid particulate polyester which contains halogen-containing polycarboxylic acid in an amount whereby the solid particulate polyester contains a halogen in an amount equivalent to 5 to 35% by weight of chlorine, the percentages by weight of the two components being calculated on the sum of the solvent-free weights thereof, said maleinized oil containing from 10-40% by weight of residues from an α-β-ethylenically unsaturated dicarboxylic acid.
Claim 3
Dependent Claim
45 words
The coating composition of claim 1, wherein the binder is made up of 30-70% by weight of the maleinized oil and 70-30% by weight of the solid particulate polyester, the percentages by weight being based on the sum of the solvent-free weights of two components.
Claim 4
Dependent Claim
33 words
The coating composition of claim 1 wherein the ratio of the alcohol component to the carboxylic acid component in the solid particulate polyester is 1 carboxyl equivalent to 1 to 4 hydroxyl equivalents.
Claim 5
Dependent Claim
30 words
The coating composition of claim 1 wherein the solid particulate polyester contains a monocarboxylic acid in a ratio of 2-10 moles of monocarboxylic acid to 8-12 equivalents of polycarboxylic acid.
Claim 6
Dependent Claim
19 words
The coating composition of claim 1 wherein the solid particulate polyester contains a cyclic chlorine or bromine-containing carboxylic acid.
Claim 7
Dependent Claim
20 words
The coating composition of claim 1 wherein the solid particulate polyester contains 12 to 19% by weight of a halogen.
Claim 8
Dependent Claim
22 words
The coating composition of claim 1 wherein the average particle size of the solid particulate polyester is smaller than about 500 μm.
Claim 9
Dependent Claim
21 words
The coating composition of claim 1 wherein the solid particulate polyester has a melting point within the range of from 20°-180°.
Claim 10
Dependent Claim
22 words
A process for coating a substrate which comprises applying the composition of claim 1 on the substrate and baking the resulting coating.
Claim 11
Independent Claim
53 words
The method for reducing the viscosity of a water-miscible malenized oil coating composition without reducing its solids content which comprises mixing with the malenized oil a solid particulate polyester prepared from components including a polycarboxylic acid which contains a halogen in an amount whereby the polyester contains 5 to 35% by weight halogen.
