(57) Abstract: An adhesive composition comprising, as a main component, a polymer obtained by introducing an aliphatic unsaturated group into a side chain of a polyvinyl acetal resin obtained by acetalizing polyvinyl alcohol. . Effect The adhesive composition of the present invention is a heat or photo-curable adhesive containing a polymer having an aliphatic unsaturated group introduced into a side chain of a polyvinyl acetal resin as a main component, and thus has high transparency and weather resistance. Excellent heat resistance, moist heat resistance, and transparency, especially since it has a crosslinked structure with an organic peroxide or a photosensitizer. |
