ADHESIVE AND LAMINATE USING THE SAME AND USED FOR PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide an adhesive which can give strong adhesive strength between laminate substrates and can maintain the strong adhesive strength over a long period, and to provide a laminate which is used for package and does not cause the temporal deterioration of the adhesive strength between the laminate substrates and the formation of pinholes, even when produced with the above-mentioned adhesive and used for charging a highly acidic food or an oily food.

SOLUTION: This adhesive comprises a polyisocyanate and a partially acid-modified polyol produced by reacting a polyol with trimellitic anhydride and trimellitate anhydride in a rate of 10 to 70 mass%: 90 to 30 mass%. The laminate is produced by laminating the first and second sheet-like substrates through the adhesive.
