<p><P>PROBLEM TO BE SOLVED: To provide a resin composition for solventless adhesives which has a great initial cohesive force and is hard to cause a dry spot in part of a film and an adhesive obtained by curing the resin composition. <P>SOLUTION: The resin composition for solventless adhesives includes a polyester polyol (A) having two or more hydroxyl groups in the molecule and at least one carboxyl group obtained by reacting part of the hydroxyl groups of the polyester polyol with a carboxylic anhydride or a polyvalent carboxylic acid and a polyisocyanate (C) having two or more isocyanate groups in the molecule, and the acid value of the resin composition for solventless adhesives is not less than 20 mgKOH/g. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
