ADHESIVE COMPOSITION, AND LAMINATE AND METHOD FOR MANUFACTURING SAME

摘要

Provided is an adhesive composition capable of realizing equal or greater adhesive performance in short-time aging relative to the prior art and that has a long pot life without strict management of the ambient temperature at a low temperature. This adhesive composition includes a polyisocyanate compound (A) and a polyol compound (B), the polyisocyanate compound (A) is a reactive product obtained by reacting 2,4'-diphenylmethane diisocyanate (a1), 4,4'-diphenylmethane diisocyanate (a2), and a polyol having a polyether polyol (a3) as an essential component thereof in an excess of isocyanate groups, and the polyol component (B) has a polyester diol (b1) having a number-average molecular weight of 500 to 3000 as an essential component thereof and furthermore includes a diol (b2) and/or a triol (b3) having a number-average molecular weight of 50 to less than 500.
