Photocurable urethane gel-state body and method for producing same

Abstract

There is provided a photocurable urethane gel-state body which has self-formability of being in a gum-state and conforming to a shape of a surface to be used by a first-stage curing, and turns to a high-hardness polyurethane by a second-stage photocuring with the self formed shape being held. The present invention relates to the photocurable urethane gel-state body which is a photocurable gel-state body containing, at least, a photocurable composition (A) containing a polyfunctional urethane (meth)acrylate and a photopolymerization initiator, and a polyurethane (B), wherein the photocurable composition (A): the polyurethane (B) is, in mass ratio, in the range of 25:75 to 55:45; and the polyfunctional urethane (meth)acrylate has no residual hydroxyl group, and to a method for producing the photocurable urethane gel-state body.
