Abstract
Abstract An acrylate modified alkyd resin obtained by the process consisting of the steps (a) forming an alkyd resin by reacting a conjugated fatty acid and an aromatic dicarboxylic acid or anhydride, and dimethylolpropionic acid with an excess of polyol, and (b) reacting the alkyd so formed with an alkyl-substituted or un-substituted acrylic acid or ester thereof or mixture thereof.

Claim 1
Independent Claim
82 words
An ammonia neutralized aqueous dispersion of a water-soluble acrylic-modified alkyd resin, said resin obtained by the process consisting of the steps of (a) forming an alkyd resin having excess hydroxy groups by reacting at elevated temperatures a fatty acid having 10-20% conjugated unsaturation and an aromatic dicarboxylic acid or anhydride and dimethylolpropionic acid with an excess amount of a polyol, and (b) reacting at elevated temperatures the alkyd resin so formed with acrylic or methacrylic acid or ester thereof or mixture thereof.
Claim 2
