Abstract: PURPOSE:To form an electrostatic charge developing toner sufficiently and uniformly chargeable to positive or negative polarity by incorporating a specified compd. to improve compatibility of dispersible components, such as colorant and charge controller, with a binder resin. CONSTITUTION:The compd. to be incorporated is represented by formula 1 in which R1 is a 1-32C straight chain or branched alkyl, alkenyl, or aryl group, such as methyl, and M is a divalent metal, such as Mg of alkaline earth metals or Zn of divalent transition metals. This compd. is embodied by formula 1-1, and this compd. is contained, preferably, in an amt. of 0.01-10pts.wt. per 100pts. wt. of a binder resin, and its preferable softening point is 90-160 deg.C measured by the KOKASHIKI flow tester, and its preferable glass transition point is >=50 deg.C.

Abstract: PURPOSE:To improve magnetic powder dispersibility, durability and surface smoothness by using a specific polyurethane resin as a binder. CONSTITUTION:The polyurethane resin having at least >=1 of an ammonium salt and/or amine salt of a COOH group in the molecular chain is used. A magnetic recording medium is produced by coating a magnetic paint for which the polyurethane resin is used as the binder and to which pulverous ferromagnetic powder and additive, etc. are added together with an org. solvent, on a non- magnetic substrate and drying the coating. The ratio of the binder and the pulverous ferromagnetic powder is 10-100pts.wt., more preferably 20-50pts.wt. by 100pts.wt. pulverous ferromagnetic powder. The mechanical strength and wear resistance are not enough if the ratio of the binder is below 10pts.wt. The magnetic powder density in the magnetic layer decreases and the satisfactory performance (reproduced output, etc.) as the magnetic recording medium is not obtainable if the ratio of the binder is increased to 100pts.wt. or above.

CONSTITUTION:The objective cosmetic contains the copolymer (especially having an average molecular weight of 30,000-200,000) composed of 98-80mol% (especially 95-85mol%) vinyl alcohol monomer and 2-20mol% (especially 5- 15mol%) 1-6C straight or branched chain alkyl vinyl ether monomer unit, as a main component. The content of the copolymer is preferably 1-40wt%. The cosmetic is a homogeneous paste or liquid having low viscosity, and accordingly, is can be spread easily and uniformly on the skin, and dried in a short time.

Abstract: PURPOSE:To obtain an oligokeratin useful as a cosmetic base material for hair, etc. at a low cost without requiring the purifying step, by treating a fibrous reduced keratin reduced without collapsing the orginal fibrous shape with a proteolytic hydrolase. CONSTITUTION:A fibrous keratin, e.g. wool, feather or hair, is reduced in a reaction medium, e.g. water and/or an alcohol, with the original fibrous shape retained. The reduced fibrous keratin is then hydrolyzed with a proteolytic hydrolase, preferably an acidic enzyme, e.g. pepsin, in water at 35-40 deg.C at a pH
