摘要： A radiation curable organopolysiloxane-containing composition is disclosed which is curable by the irradiation with actinic rays in a relatively low dose to give a cured layer having excellent surface-releasability so that the composition is useful, for example, as a coating agent of release paper for temporary protection of adhesive surface. The composition comprises (a) 0.1 to 20 parts by weight of a linear organopolysiloxane having at least one vinylphenyl or isopropenylphenyl group bonded to only one of the terminal silicon atoms in the molecular chain and (b) 99.9 to 80 parts by weight of a (meth)acrylate compound which is a (meth)acrylic acid ester of a polyhydric alcohol or a polyester of a polyhydric alcohol and a dibasic carboxylic acid esterified with (meth)acrylic acid at the residual hydroxy groups.

摘要： A radiation-curable surface-releasing agent is proposed which is capable of giving surface releasability to a substrate surface by irradiation with electron beams or ultraviolet light exhibiting outstandingly low peeling resistance against peeling of pressure-sensitive adhesive tapes applied and bonded to the release-treated surface and very small migration of the releasing ingredient toward the adhesive surface. The surface-releasing agent is a composition comprising a linear diorganopolysiloxane having, only at one of the molecular chain ends, at least one (meth)acryloxy groups and a poly(meth)acrylate compound such as trimethylol propane tri(meth)acrylate, diethylene glycol di(meth)acrylate, pentaerithritol tri(meth)acrylate and the like.
摘要翻译：提出了一种可辐射固化的表面释放剂，其能够通过用电子束或紫外线照射给基材表面提供表面可剥离性，该紫外线表现出显着低的抗剥离性，从而剥离施加并结合到脱模处理过的粘合带表面和释放成分向粘合剂表面的非常小的迁移。表面释放剂是包含直链二有机聚硅氧烷的组合物，其仅在一个分子链末端具有至少一个（甲基）丙烯酰氧基和聚（甲基）丙烯酸酯化合物，如三（甲基）丙烯酸三羟甲基丙酯，二亚乙基乙二醇二（甲基）丙烯酸酯，季戊四醇三（甲基）丙烯酸酯等。
