Title: ADHESIVE FOR LAMINATED SHEETS
Abstract:
Disclosed is an adhesive for laminated sheets, which adhesive is applied to a film to bond a plurality of films, and is a mixture comprising: (A) an acrylic polyol, (B) at least one selected from carboxylic acids and carboxylic anhydrides; and (C) an isocyanate compound, wherein the (B) is mixed in an amount of 0.01 to 8.0 parts by weight per 100 parts by weight of the total of the (A)-(C), and wherein the (A) is obtainable by polymerizing a polymerizable monomer, and is a polymer having a weight average molecular weight of 10,000 to 100,000 and a hydroxyl value of 0.5 to 40 mgKOH/g. The adhesive for laminated sheets is excellent in coatability, peel strength after curing and hydrolysis resistance for a long time under high temperature when a laminated sheet is produced, and wherein the adhesive for laminated sheets does not impart an adverse effect to the appearance of the laminated sheet while improving the curability. A laminated sheet is suitably prepared using the adhesive for laminated sheets.
