More Information
Summary:In an active energy ray-curable polyurethane resin including a reaction product of a resin material containing an isocyanate group-terminated prepolymer and a hydroxy group-containing unsaturated compound, the isocyanate group-terminated prepolymer includes a reaction product of a prepolymer material containing a polyisocyanate component containing a xylylene diisocyanate and/or a hydrogenated xylylene diisocyanate, and a polyol component containing a polyoxyalkylene polyol having a number average molecular weight of 6000 or more and 12000 or less, and the viscosity at 25° C. of the active energy ray-curable polyurethane resin is 20000 mPa·s or more and 40000 mPa·s or less.
