ADHESIVE COMPOSITION FOR LAMINATING HAVING EXCELLENT RETORT RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a two-part curing adhesive composition for laminating having excellent retort resistance.;SOLUTION: This two-part curing adhesive composition for laminating comprises a polyester-polyol obtained by reacting a polybasic acid with a polyhydric alcohol as a principal component and a polyisocyanate as a curing agent. In the two-part curing adhesive composition, the polybasic acid is characterized by comprising at least (1) a dimer acid containing ≤10 mass% of a monomer acid component, ≥70 mass% of a dimer acid component and ≤20 mass% of a trimer acid component and (2) one or more kinds selected from othophthalic acid, terephthalic acid and isophthalic acid in an amount of 1.5-3.0 mmol/g based on the polyester-polyol.;COPYRIGHT: (C)2003,JPO
