PURPOSE: Provided is a non-aqueous lamination adhesive which has long life of reactor, and excellent storage stability, productivity, and workability, while aging time is reduced. CONSTITUTION: The adhesive comprises (A) t-amino group-containing polyurethane resin obtained by reacting an active hydrogen group-containing compound comprising at least one or two or more compounds selected from the group consisting of compounds represented by formula 1, 2, 3, and 4, respectively, with organic polyisocyanate in the presence of excess active hydrogen group; and (B) polyisocyanate hardener, wherein the t-amino group-containing polyurethane resin(A) contains 0.01-1 mmol/g of t-amino group. In the formulas, R1 is a monovalent hydrocarbon group of C1-C10, each of R2 and R3 may be the same or different, and represents divalent hydrocarbon of C1-C10, each of R4 and R5 may be the same or different, and represents divalent organic group of C1-C10, R6 is a C1-C10, trivalent hydrocarbon group, each of R7 and R8 may be the same or different, and represents a monovalent hydrocarbon group of C1-C10, each of R9 and R10 may be the same or different, and represents a divalent organic group of C1-C10, each of a and b is an integer of more than 0, which allows the compound of formula 2 to have number average molecular weight of 300-10,000, and each of c and d is an integer of more than 0, which allows the compound of formula 4 to have number average molecular weight of 300-10,000.
