Abstract: Disclosed is an adhesive for laminated sheets comprising a urethane resin obtained by blending: (A) an acrylic polyol; (B) at least one component selected from carboxylic acids and carboxylic anhydrides; and (C) an isocyanate compound. The acrylic polyol (A) is obtained by polymerization of a polymerizable monomer, has a glass transition temperature of from ?35 ° C. to 20° C., and has a hydroxyl value of from 0.5 to 40 mgKOH/g. The adhesive for laminated sheets is excellent in initial adhesion to a film, peel strength after aging and hydrolysis resistance for a long time under high temperature when a laminated sheet is produced, and wherein the adhesive does not impart an adverse effect to the appearance of the laminated sheet and the lamination process of films while improving the curability. The laminated sheet is suitably prepared using the adhesive for laminated sheets. An article comprising the laminated sheet can be prepared using the laminated sheet.
