Abstract
Abstract A paint composition comprises (A) 30 to 70 percent by weight of an oil-modified alkyd resin of an oil length of 30 to 70 percent which has been modified with sorbic acid, crotonic acid, or 2-( beta -furyl) acrylic acid, the content of which is 0.5 to 30 percent by weight and (B) 70 to 30 percent by weight of a polymerizable monomer in which the oil-modified alkyd resin is dissolved.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
An oil-modified alkyd resin composition comprising: from 30 to 70 percent by weight of an ingredient (A) comprising an oil-modified alkyd resin of an oil length of from 30 to 70 percent which is a poly condensation reaction product of: (a) a polybasic acid, (b) a polyhydric alcohol, (c) a saturated or unsaturated fatty acid or oil, and (d) an α,β-unsaturated monocarboxylic acid selected from the group consisting of sorbic acid, crotonic acid, and 2-(beta-furyl)acrylic acid, the content of the α,β-unsaturated monocarboxylic acid in the alkyd resin being 0.5 to 30 percent by weight; and from 70 to 30 percent by weight of an ingredient (B) comprising a polymerizable monomer having a boiling point higher than 200° C. in which the ingredient (A) is dissolved.
Claim 2
Dependent Claim
125 words
An oil-modified alkyd resin composition comprising: from 30 to 70 percent by weight of an ingredient (A) comprising an oil-modified alkyd resin of an oil length of from 30 to 70 percent which is a poly condensation reaction product of: (a) a polybasic acid, (b) a polyhydric alcohol, (c) a saturated or unsaturated fatty acid or oil, and (d) an α,β-unsaturated monocarboxylic acid selected from the group consisting of sorbic acid, crotonic acid, and 2-(beta-furyl)acrylic acid, the content of the α,β-unsaturated monocarboxylic acid in the alkyd resin being 0.5 to 30 percent by weight; and from 70 to 30 percent by weight of an ingredient (B) comprising a polymerizable monomer having a boiling point higher than 200° C. in which the ingredient (A) is dissolved.
Claim 3
Dependent Claim
