PROBLEM TO BE SOLVED: To provide an adhesive composition that can be used in a short time aging step of 2 to 3 days at 40°C, and can sufficiently achieve the hot water spray type retort resistance.SOLUTION: Provided is an adhesive composition containing an isocyanate component (A) and a hydroxyl component (B), and in which: the content of isocyanate group in the isocyanate component (A) is within a particular range; the isocyanate component (A) contains an isocyanate group-containing polyether polyurethane (A1) obtained by reacting a hydroxyl component (a1) essentially having a polyether diol with a particular molecular weight (a1-1), and a 4,4'-diphenyl methane diisocyanate (a2) by a particular NCO/OH, and a 4,4'-diphenyl methane diisocyanate (a2), and exhibits a specific viscosity; and the hydroxyl component (B) is a polyester polyol with a particular molecular weight and/or a polyester polyurethane polyol.SELECTED DRAWING: None |
