A process is disclosed, which enables production of alkyd resins within a short time, by conducting depolymerization and esterification reactions of polyester resins whose main starting material is terephthalic acid and which have been recovered from waste materials and regenerated, in a mixture of a polyhydric alcoholic component comprising tetra- or higher alcohol, an oil and fat and/or a fatty acid, and a polybasic acid component. |
