Title:
ACTIVE-ENERGY-RAY-CURABLE HOT-MELT URETHANE RESIN COMPOSITION, MEMBER FOR ELECTRONIC DEVICE WHICH COMPRISES THE COMPOSITION, AND PACKING
Document Type and Number:
WIPO Patent Application WO/2012/032885
Kind Code:
A1
Abstract:
An active-energy-ray-curable hot-melt urethane resin composition comprising a hot-melt urethane (X) and an active energy ray polymerization initiator (Y), wherein the hot-melt urethane (X) is produced by reacting an isocyanate-terminal urethane prepolymer (C) with a hydroxy group contained in a (meth)acrylic compound (D) containing a reactive functional group to convert more than 50% and not more than 100% of the total number of isocyanate groups contained in the isocyanate-terminal urethane prepolymer (C) into terminal (meth)acryloyl groups, and wherein the isocyanate-terminal urethane prepolymer (C) is produced by reacting a polyol component (A) that comprises an aromatic polyester polyol (a1) containing 90 mol% or more of a 2,2-dimethyl-1,3-propylene structure in a glycol component in the molecule and a polyol (a2) other than the component (a1) with a polyisocyanate component (B). The composition exhibits both hot melt properties and rapid curability upon irradiation with UV ray or the like, and has excellent properties including shape-retaining properties after application, flexibility, durability, a property of adhering to a base, a low outgas property, mechanical strength and flame retardancy.
