Latest Patents
Shoko Ito's latest patents include a urethane adhesive for laminated sheets. This adhesive comprises a urethane resin obtained by blending an acrylic polyol, carboxylic acids or carboxylic anhydrides, and an isocyanate compound. The acrylic polyol is synthesized through the polymerization of a polymerizable monomer, exhibiting a glass transition temperature ranging from -35 °C to 20 °C, and a hydroxyl value between 0.5 to 40 mgKOH/g. The adhesive demonstrates excellent initial adhesion to films, peel strength after aging, and hydrolysis resistance under high temperatures. It is designed to enhance the lamination process without adversely affecting the appearance of the laminated sheet.
Another patent focuses on an adhesive for laminated sheets that includes a urethane resin created by mixing an acrylic polyol with an isocyanate compound. The acrylic polyol is derived from a mixture that includes a first monomer with a hydroxyl group and acrylonitrile. This formulation includes both aromatic and non-aromatic isocyanate compounds, resulting in cured reaction products that are effective for films laminated using the adhesive.
