| abstract | INDUSTRIAL APPLICABILITY The present invention exhibits excellent flexibility, has a small temperature dependence of viscoelasticity from low temperature to high temperature, is particularly excellent in adhesive strength to polar adherends, and can easily control the increase in molecular weight. It is an object of the present invention to provide a urethane pressure-sensitive adhesive having well-balanced performance with high film strength and less contamination of the adherend. The present invention is a pressure-sensitive adhesive containing a polyurethane resin containing a polyol component (A) having no amino group and an isocyanate component (B) as essential constituent monomers, and the weight average molecular weight of the polyurethane resin is 5. The polyol component (A) which is 10,000 to 2 million and does not have an amino group contains a polyoxyalkylene polyol (a1), and the molecular end of the polyoxyalkylene polyol (a1) is a hydroxypropyl group and The primary hydroxyl group content is at least 40%, and the 180 ° peel strength under the condition of a tensile speed of 300 mm / min at 23 ° C. when bonded to a glass plate while being pressure-bonded with a 2 kg roller is 5 to 50 N / 25 mm. It is a pressure-sensitive adhesive. |
