Document Type and Number:
WIPO Patent Application WO/2022/202832
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing an adhesive agent composition and a coating composition each having excellent storage stability, high adhesiveness, and excellent blocking resistance and water resistance. [Solution] Provided is a crystalline polyester resin which contains a polycarboxylic acid component and a polyhydric alcohol component as copolymerization components, in which 30 to 70 mol% of terephthalic acid, 10 to 60 mol% of a 1,4-cyclohexanedicarboxylic acid and 5 to 30 mol% of an aliphatic dicarboxylic acid having 10 or less carbon atoms are contained as the polycarboxylic acid component, the content of an aromatic dicarboxylic acid component having a sulfonic acid base is less than 3 mol%, 50 to 100 mol% of 1,4-butanediol is contained as the polyhydric alcohol component, and the crystalline polyester resin has an acid value of 100 to 600 eq/t, a glass transition temperature of -30 to 30°C, a melting point of 70 to 160°C, and a number average molecular weight of 5000 to 40000.
