ABSTRACT:
A liquid polyester obtained by reacting a cyclic acid anhydride (A) containing at least 10 mol % of one of specific cyclic acid anhydrides with an epoxy compound (B) in a cyclic acid anhydride (A):epoxy compound (B) molar ratio of 10:8-10:12, can be applied with a conventionally generally used film-forming machine such as a roll coater or a printing machine, can easily give a film-forming material such as a solvent-free coating composition or ink and a curable liquid resin for use as an adhesive, is a low-temperature curing liquid polyester useful as a compatibilizer, a surface-tension modifier, a pigment dispersing agent and a metal chelating agent, and is curable in air in the presence of a relatively small amount of a catalyst.
