Abstract: An antibacterial composition containing an organic antibacterial agent and an inorganic antibacterial agent is provided. Zirconium phosphate having supported thereon silver or copper or a salt thereof may be used as the inorganic antibacterial agent, and 2-mercaptopyridine-N-oxide sodium, carbendazim (methyl 1H-2-benzimidazole carbamate), or thiabendazole (2-(4-thiazolyl)-1H-benzimidazole) may be used as the organic antibacterial agent. Those components contain no halogen, so the antibacterial composition can be made halogen-free. The antibacterial composition may be applied to form an antibacterial molding, for example, by molding it together with a resin material or applying it together with a coating agent on a resin molding.

Abstract: A deodorant includes a powder of an amine salt of a phosphorus inorganic acid, the powder having an average particle diameter of 0.1 to 30 ?m. The amine salt of a phosphorus inorganic acid is preferably an ammonium salt. Deodorant products including the deodorant such as an adhesive, a paint and a foamed material can be substantially reduced in formaldehyde emission therefrom, and can deodorize formaldehyde existed in the environment.

Abstract: A heat-accumulative material composed of a polymer or oligomer having a melting point of ?10 to 100° C. and latent heat of 30 J/g or more for use around a body, and heat-accumulative composition comprising the same heat-accumulative material. The heat-accumulative material tends to be kept at a constant temperature more effectively by absorbing heat as ambient temperature increases to melt, and releasing heat as ambient temperature decreases to solidify, to moderate the effect of changed ambient temperature, and thereby to exhibit the function as a heat-accumulative material. They have a sufficiently high viscosity, preventing the heat-accumulative material from flowing out even when it is molten. Each of the heat-accumulative material and composition can be made into a heat-accumulative film or sheet, laminate, molded article, composite fiber and cloth which can be suitably used around a body.

Abstract: A polypropylene-based calendered or injection-molded article satisfying the requirements of (1) having a tensile modulus TM of 5 MPa or higher and (2) having, when measured by a differential scanning calorimeter (DSC), no melting point or a melting point Tm (° C.) satisfying the formula: TM≧5×Tm−450, is less tacky and excellent in flexibility and transparency. Such a polypropylene-based calendered or injection-molded article is produced from a propylene polymer satisfying the requirements of (1) having a component soluble in a 25° C. hexane in a content H25 of 0 to 80% by weight; (2) having, when measured by a differential scanning calorimeter (DSC), no melting point or a melting point Tm (° C.) satisfying the formula: &Dgr;H≧6×(Tm−140) wherein &Dgr;H is a melting endotherm (J/g); and (3) having an intrinsic viscosity [&eegr;] of 1 to 3 dl/g as measured at 135° C. in tetralin.

Abstract: A resin composition contains a thermoplastic elastomer, natural organic, and silicone. As the thermoplastic elastomer, an olefin thermoplastic elastomer, such as a ethylene-propylene copolymer or the like, can be used. As the thermoplastic elastomer, a styrene thermoplastic elastomer, such as a styrene-butadiene copolymer or the like, can be used. As the natural organic, silk, cellulose, collagen or the like can be used. It is advisable that the content of the natural organic is 5-30 wt %, and the content of silicone is 0.3-10 wt %. Where the natural organic is a fine powder state, it is preferable that the particle size is less than 300 &mgr;m. Moldings are sheets or the like, formed by using the aforementioned resin composition.

Abstract: Materials containing fine natural organic material particles are disclosed. As the fine particles, superfine silk fibroin particles are produced by a process comprising a first step of comminuting silk fibroin into coarse particles with dry mechanical comminuting means, a second step of comminuting the coarse silk fibroin particles into fine particles with dry mechanical comminuting means, and a third step of comminuting the fine silk fibroin particles into superfine particles with an average particle diameter of 10 .mu.m or below with dry mechanical comminuting means, the silk fibroin particles being beta-treated during or after at least one of the first to third comminuting steps. Specific examples of the material are films, sheets, paints, fiber treating materials, etc.
