ADHESIVE COMPOSITION AND LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide an adhesive hardly receiving effects of moisture in air during curing, having good workability when used as a solventless type adhesive and excellent in adhesive strength and acid resistance in a laminate composite film containing a metal foil used in a high temperature sterilization treatment.SOLUTION: There is provided a manufacturing method of an adhesive composite including a step of reacting (C2) a ≥3 functional isocyanate compound and (D) monofunctional alcohol with an isocyanate group in the compound (C2):the monofunctional alcohol (D)=100 mol%:25 to 65 mol% to obtain (E) alcohol added isocyanate and a step of mixing (C1) ≥3 functional isocyanate compound, (A) polyisocyanate containing the (E) and (B) alcohol having acid value of 0.5 to 30 mgKOH/g so that equivalent ratio of the isocyanate group in the (A) and a hydroxyl group in the (B) (isocyanate group/hydroxyl group) is 0.7 to 2.5.SELECTED DRAWING: None
