<P>PROBLEM TO BE SOLVED: To provide a one-part adhesive capable of satisfactorily bonding a base material and a primer layer together. <P>SOLUTION: The adhesive is obtained by mixing a urethane-modified acrylic resin, prepared by bringing (A) an acrylic polyol, (B) a polycarbonate diol and (C) an organic diisocyanate into a urethanization reaction, with (D) a polycaprolactone resin. In the urethane-modified acrylic resin, the mass ratio of the polycarbonate diol (B) and the organic diisocyanate (C) to the acrylic polyol (A): (A)/((B)+(C)) is 50/50 to 90/10, and the mixing ratio between the urethane-modified acrylic resin and the polycaprolactone resin (D) (expressed in terms of solid) is 99.5/0.5 to 80/20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
