Title:
ADHESIVE COMPOSITION AND LAMINATE
Document Type and Number:
WIPO Patent Application WO/2016/104510
Kind Code:
A1
Abstract:
Provided is an adhesive agent which, in a metal foil-containing laminate composite film used in high temperature sterilization treatment, is hardly affected by moisture in air during curing, exhibits good workability when used as a solventless adhesive agent and exhibits excellent adhesive strength and acid resistance. Provided is a method for producing an adhesive composition, the method including: a step of obtaining an alcohol-added isocyanate (E) by reacting a trifunctional or higher isocyanate compound (C2) and a monofunctional alcohol (D) at an equivalence ratio such that the ratio of isocyanate groups in the trifunctional or higher isocyanate compound (C2) : monofunctional alcohol (D) is 100 mol.% : 25-65 mol.%; and a step of mixing a polyisocyanate (A), which contains a trifunctional or higher isocyanate compound (C1) and the alcohol-added isocyanate (E), with an alcohol (B) having an acid value of 0.5-30 mg KOH/g so that the equivalence ratio of isocyanate groups in the polyisocyanate (A) and hydroxyl groups in the alcohol (B) (isocyanate groups/hydroxyl groups) is 0.7-2.5.
