Patent ID: 6887909

Claim:
A process for producing an aqueous alkyd resin dispersion which is characterized by comprising: (A-1) a step of synthesizing an alkyd resin by depolymerizing polyester resin whose chief starting material is terephthalic acid and which has been recovered from waste materials and regenerated, while carrying out its esterification at the same time, by dissolving the polyester resin in a mixture of an alcoholic component in which the weight ratio of tri- or lower polyhydric alcohol to tetra- or higher hydric alcohol as the former/latter is within a range of 0-20, a fatty acid and/or an oil and fat, and polybasic acid component, and (C-1) a step of dispersing the alkyd resin, which is obtained in the above step (A-1), in water, in the presence of 3-15 parts by weight of surfactant per 100 parts by weight of said alkyd resin.
