Molding

Abstract

Abstract PURPOSE:To obtain a molding which is excellent in adhesion and has durability by blending a multifunctional acryl compd., a foaming agent and a photopolymerization initiator at the specified amounts with the specified acrylate or methacrylate and applying this blended composition to a base material and irradiating the base material with ultraviolet rays to polymerize and foam the blended composition. CONSTITUTION:0.01 - 5pts.wt. multifunctional acryl compd., 0.0001 - 3 pts.wt. foaming agent and 0.1 - 5 pts.wt. photopolymerization initiator are blended with 100pts.wt. acrylate or methacrylate having 4 - 18 C alkyl group. A molding is obtained by applying this blended composition to a base material and irradiating it with ultraviolet rays to polymerize and foam this composition. In the amount excepting a range within 0.01 - 5pts.wt. multifunctional acryl compd., the adhesion is deteriorated. When the foaming agent is less than 0.0001pts.wt., the effect thereof can be not exhibited. When this foaming agent exceeds 3pts. wt., foaming is excessively performed and the adhesion is deteriorated. When the photopolymerization initiator is less than 0.1pts.wt., (meth)acrylate and the multifunctional compd. are not cured. When it exceeds 5pts.wt., the adhesion is deteriorated.
