PURPOSE:The titled economical composition, consisting of a powder component consisting of a specific composition containing powdery rubber and a liquid composition containing an acrylic ester, and having improved peel and impact strength without requiring operation to dissolve the rubber in the acrylic ester. CONSTITUTION:An adhesive composition obtained by incorporating (A) a powder component prepared by incorporating (i) powdery rubber with (ii) an organic peroxide, e.g. dicumyl peroxide, or (iii) a decomposition accelerator, e.g. ethylenethiourea, for the organic peroxide with (B) a liquid component prepared by incorporating (iv) an acrylic ester with the component (iii) or (ii) in use. Both the components (ii) and (iii) must not be mixed with the respective components (A) and (B) at the same time. Preferably, the compounding ratios are as follows; 0.1-30wt% component (ii) and 0.1-25wt% component (iii) based on the acrylic ester.
