Abstract: The present invention provides a novel base material for a dry solid dispersion, a solid dispersion containing the base material, and a composition containing the dispersion; the solid dispersion of the present invention, which contains a poorly soluble component with improved dissolvability, can be obtained by mixing a polyvinyl alcohol-based copolymer, as a base material for the dry solid dispersion, with a poorly soluble component, and then heating it.

Abstract: The present invention relates to a novel resin composition useful as a coating agent or a binder for medicines, drugs for animals, agricultural chemicals, fertilizers, foods or the like, which contains a polyvinyl alcohol copolymer as a main component. More particularly, the present invention relates to a resin composition, characterized in that the composition is obtained by copolymerizing a polyvinyl alcohol having an average polymerization degree of 1300 or less, and at least one polymerizable vinyl monomer in a weight ratio of 6:4 to 9:1.

Abstract: The present invention provides a foam-type external skin preparation exhibiting an amount of and a retention of carbon dioxide foam appealing to the eye of the user, as well as good usability, such as in preventing the preparation from sagging from the skin, neither of which can be easily obtained with conventional foam-type external skin preparations. The present invention provides a foam-type external skin preparation containing a hydrophobically modified alkyl cellulose as an essential component.

Abstract: An object of the invention is to provide a pressure-sensitive adhesive sheet. Provided is an acrylic polymer for use in a pressure-sensitive adhesive composition for a touch screen panel, the acrylic polymer being obtained by copolymerizing monomer components comprising (a) a (meth)acrylic acid ester monomer having a C1-12 hydrocarbon group, (b) a hydroxy group-containing (meth)acrylic acid ester monomer, (c) an amide group-containing monomer, and (d) a vinyl ester monomer. The acrylic polymer has an acid value of 0.1 mg KOH/g or less, a weight-average molecular weight of 400,000 to 2,000,000, a Tg of ?80 to 0° C., and a permittivity of 3 to 6.

Abstract: In the production method of the present invention, an emulsion including a copolymer with a glass transition temperature (Tg) of ?50 to 20° C. is obtained by the emulsion polymerization of a monomer group including a monomer A that is a (meth)acrylic acid alkyl ester (where the alkyl group is an open chain group with 1 to 20 carbon atoms or a cyclic group with 5 to 20 carbon atoms) as the main monomer and a monomer B having a carbon-carbon double bond and a nonionic hydrophilic group such as a polyoxyalkylene group, an amide group, and a hydroxyl group. Liquid crystals are dispersed in this emulsion, which is applied onto a conductive film-coated substrate. Another conductive film-coated substrate is laminated thereto, and thus a liquid crystal light control device is obtained. A monomer C having a carboxyl group and/or an amino group and a carbon-carbon double bond may be used in combination with a crosslinking agent so that a crosslinked structure is introduced into the copolymer.

Abstract: A hard capsule which is made mainly of a polymer or copolymer obtained by polymerizing or copolymerizing at least one polymerizable vinyl monomer in the presence of polyvinyl alcohol and/or a derivative thereof. Unlike conventional hard capsules, this hard capsule can be filled with a solvent (e.g., polyethylene glycol) for a sparingly soluble drug ingredient.
