Title:
URETHANE ADHESIVE FOR LAMINATED SHEETS
Document Type and Number:
WIPO Patent Application WO/2016/088337
Kind Code:
A1
Abstract:
Disclosed is an adhesive for laminated sheets comprising a urethane resin obtainable by blending: (A) an acrylic polyol; (B) at least one selected from carboxylic acids and carboxylic anhydrides; and (C) an isocyanate compound, wherein the acrylic polyol (A) is obtainable by the 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.
