<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition that can form an adhesive layer excellent in initial adhesive strength (tack), adhesion to a substrate, heat resistance, moist heat resistance and transparency, and a laminated product obtained by using the pressure-sensitive adhesive composition. <P>SOLUTION: The pressure-sensitive adhesive composition comprises an addition type polyester resin (A) having a side chain, which is obtained by ring-opening addition of a cyclic ester compound (b) and successive addition of a compound (c) adding to a hydroxy group to a polyester resin (a) bearing a hydroxy group, obtained by a polyaddition reaction of a polybasic acid (a-1) bearing at least two carboxy groups and a compound (a-2) bearing two cyclic ether groups in the molecule, and a reactive compound (B) reactive with the functional group in the addition type polyester resin (A). <P>COPYRIGHT: (C)2008,JPO&INPIT |
