UV HYDROXYL-CONTAINING POLYURETHANE RESIN POLYURETHANE RESIN AND URETHANE METHACRYLATE RESIN USING HYDROXYL-CONTAINING POLYURETHANE RESIN AS STARTING MATERIAL PRODUCTION METHODS FOR THESE RESINS OVERCOAT COMPOSITION AND UV-CURABLE RESIN COMPOSITION

摘要

A protective film resin excellent in environmental resistance and scratch resistance as a protective film of metal nanowires and capable of being cured by radiation such as UV rays is provided. A polyurethane skeleton (A) having a carboxyl group, an alkenoxide ring-opening adduct represented by the following formula (b1) bonded to at least a part of the carboxyl group or an aliphatic alcohol having a cycloalkane ring-opening adduct represented by the formula (b2) Wherein the hydroxy-containing polyurethane resin comprises an oxy-ring-opening addition portion (B). (In the formula (b1), n ₁ is an integer of ₁ to 50, R ¹ and R ² are each independently a hydrogen atom, an alkyl group having 1 to 16 carbon atoms or a phenyl group. Wherein (b2) of, n ₂ is an integer of 1~10, Z are carbon atoms, including from 2 individual carbon atom to which the bond Z is a group of atoms to form an individual 4-14 alicyclic hydrocarbon group;
