(Problem) Provided the active energy ray hardening-type adhesive composition which is excellent in adhesive force even under the conditions of high temperature or high humidity, there is little coloring in long-term use, and a composition does not precipitate in a cold district. (Solving means) (A) a polyester backbone, or a polycarbonate urethane having a skeleton (meth) acrylate, (B) at least one group -C (CH 3) 2 in the group R (R represents an alkyl group or a phenyl group), a An active energy ray hardening-type adhesive composition containing the phenol compound, (C) phosphite ester compound (however, it has solubility in a composition), and (D) compound which has ethylenically unsaturated groups other than the said (A) component. |
