Summary:PURPOSE:To provide a moisture-curing self-adhesive compsn. having excellent storability and self-adhesiveness and high bonding strength, prepared by blending a specified polymer having an isocyanater group in its side chain, with an isocyanater group-contg. tackifier. CONSTITUTION:The self-adhesive compsn. consists of (1) a polymer having an isocyanate group in its side chain obtained by reacting 30mol% (meth) acryloyl troup-contg. unsatd. isocyanate with 70-99mol% monomer copolymerizable with the unsatd. isocyanate and (2) an isocyanate group-contg. tackifier. Preferred monomers for (1) are those which form a polymer with a glass transition point of below 30 deg.C. The polymer having an isocyanate group in its side chain is usually prepared by solution polymerization of (1) and (2).
