To obtain a subject composition comprising a urethane (meth)acrylate, a polymerization initiator and polymer particles, excellent in the slipping property of the surface of a cured product, excellent in curability and durability and useful for air-blown fibers.
This liquid curable resin composition comprises (A) a urethane (meth)acrylate, (B) a polymerization initiator and (C) polymer particles having an average particle diameter of 5μm to 1mm. The component A is obtained e.g. by reacting a polyol with a diisocyanate and an OH group-containing (meth) acrylate. The component B is e.g. a radical polymerization initiator and/or a radiation polymerization initiator, and the component C is e.g. acrylic resin particles. (D) A reaction diluent is preferably further added to the composition in an amount occupying the 20-70wt.% of the composition. The objective composition has a viscosity of 2000-15000cp at 25°C.
