Document Type and Number:
WIPO Patent Application WO/2022/239667
Kind Code:
A1
Abstract:
Provided is a method for producing a laminate that has excellent curing speed and has no pot-life issues even when a solvent-free adhesive having oxygen barrier properties is used. The method for producing a laminate is characterized by comprising: a step for coating a first substrate with a first composition containing a polyisocyanate compound; a step for coating a second substrate with a second composition containing a compound which has an active hydrogen group; a step for pasting the first substrate and the second substrate together so that the first composition and the second composition come into contact; and a step for causing the first composition and the second composition to react to form an adhesive layer, the adhesive layer having an oxygen transmission rate of 300 cc/m2·day·atm or less.
