Abstract: An object of the present invention is to provide microsphere particles containing powdered cellulose, which have an excellent massage effect, a high cleansing effect, and excellent dispersibility. A microspherical particle comprising powdered cellulose meets the following condition of (A) or (B): (A) an average particle diameter of less than 50 ?m, and a sphericity of 0.1 or more to 1.0 or less; or (B) the microspherical particle has an average particle diameter of 50 to 100 and a sphericity of 0.1 or more to less than 0.7.

Abstract: An object of the present invention is to provide a microspherical particle having an excellent massage effect. Another object of the present invention is to provide a microspherical particle that provides an excellent massage effect and cleaning effect when formulated in a cleaning composition and the like. A microspherical particle is formed of powdered cellulose so that the microspherical particle has an average particle diameter of 50 to 2,000 ?m, a sphericity of 0.7 to 1.0, and a dry hardness of 1 to 5,000. A soft type thereof has a dry hardness of 1 to less than 210, and a hard type thereof has a dry hardness of 210 to 5,000. Such microspherical particle is formulated to make a massage composition or a cleaning composition.

Abstract: It is an object of the present invention to provide an active energy ray curable resin composition exhibiting good adhesion to a polyolefin-based resin base material. More specifically, there is provided an active energy ray curable resin composition comprising: a block copolymer (C) that includes a polymer block (A) composed mainly of an olefin-based monomer unit and a polymer block (B) composed of a vinyl-based monomer unit having a carboxyl group, a carboxylic anhydride group, or a sulfonic acid group and/or a second vinyl-based monomer unit copolymerizable with the aforementioned vinyl-based monomer unit, the block copolymer (C) having a weight-average molecular weight from 5,000 to 100,000; and an active energy ray curable compound (D).
