    摘要： A polyisocyanate curing agent for laminate adhesive, comprising: (A) an isocyanate group-terminated prepolymer having isocyanurate group and urethane group, obtained by reacting an organic polyisocyanate containing at least (a1) an aromatic diisocyanate with an active hydrogen group-containing compound containing at least (a2) a diol compound having a number-average molecular weight of 100 to 2,000, and, as an optional component, (B) an isocyanate group-terminated prepolymer having urethane group, and, also as an optional component, (C) a silane coupling agent represented by the following general formula (1): OCN—(CH2)m—Si(OR)3  (1)  (wherein R is a methyl group or an ethyl group, and m is an integer of 1 to 5); and a process for producing the polyisocyanate curing agent. The polyisocyanate curing agent is usable in a laminate adhesive which can be aged in a short time without shortening the pot life, which has good adhesivity, and which can withstand a severe retort treatment.
