    Abstract: NEW MATERIAL:A compound expressed by formula I (n is an integer 1-3). EXAMPLE:N-(2-Mercaptoethyl)gluconamide. USE:A water-soluble and odorless reducing agent for the first agent in cold permanent wave and polymerization degree regulator in radical polymerization. PREPARATION:A glucone-delta-lactone expressed by formula II is mixed or suspended in an aminoalkanethiol expressed by formula III in a solvent, e.g. methanol, and heated while refluxing and stirring. Alternatively, the aminoalkanethiol is first dissolved in the solvent, and the glucono-delta-lactone is then added to the reaction system is portions to afford the aimed compound expressed by formula I.

    Abstract: PURPOSE:To obtain a developer prevented from offset without using an offset preventing liquid and fixable at a lower fixing temp. by using a binder resin composed essentially of a vinyl type polymer obtained by polymerizing a vinyl type monomer with a vinyl type cross-linking agent in an amt. of 0.005wt% of the monomer. CONSTITUTION:The binder resin is prepared by copolymerizing a styrene or its deriv. for forming the main skeleton of the resin, with an ethylenic monocarboxylic acid or its ester for controlling the thermal characteristics, such as softening point, triboelectrifiability and triboelectrification amt. As the vinyl type crosslinking agent, a compd. having >=2 double bonds, such as divinylbenzene, is used. The absolute value of the inclination of the apparent viscosity measured with the flow tester of the KOKA Method is regulated to =2.0X10 poise in the viscosity range of 1.0X10 -1.0X10 poise. The softening point of this flow tester is, preferably, within 100-160 deg.C.

    Abstract: PURPOSE:To obtain a high reproduced output and high durability by using pulverous ferromagnetic iron oxide powder having a specific surface area and a binder consisting of a polyurethane resin having SO3M groups. CONSTITUTION:The pulverous ferromagnetic iron oxide powder has /g specific surface area and the binder is the polyurethane resin having >=1 SO3M groups (where M is H, Li, Na or K) for each 1mol. The pulverous ferromagnetic iron oxide powder is enumerated by mixed crystals composed of r-Fe2O3, r-Fe2O3 and Fe3O4 or these magnetic materials deposited or doped with Co, etc. The pulverous ferromagnetic iron oxide powder having the specific surface area larger than 30m /g is relatively highly rugged in magnetic particle surface and is susceptible to damage by the friction with a magnetic head and therefore there is a problem in terms of durability. The successful dispersion of the powder into the urethane resin is not possible and eventually the high reproduced output and high durability are not obtainable. The number average mol. wt. of the polyurethane resin is preferably 5,000-50,000.

    Abstract: PURPOSE:To obtain high reproduced output and high durability with short wavelength recording by using ferromagnetic metallic powder having a specific surface area and a binder consisting of a specific polyurethane resin. CONSTITUTION:The ferromagnetic metallic powder used has /g specific surface area and the binder is the polyurethane resin having >=1 SO3M groups (where M is H, Li, Na or K) for each one molecule. The ferromagnetic metallic powder is exemplified by metallic powder such as Fe, Co and Ni or ferromagnetic alloy powder of Fe-Co, Fe-Ni, Co-Ni, Fe-Co-Ni, etc. The ferromagnetic metallic powder having >=40m /g specific surface area is relatively highly rugged in the magnetic particle surface and is susceptible to damage by the wear with a magnetic head and therefore there is a problem in the durability. In addition, the successful dispersion of the powder into the urethane resin is not possible and eventually the high reproduced output and high durability are not obtainable. The number average mol. wt. of the polyurethane resin is preferably 5,000-50,000.

    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 respectively among 3 kinds of polar groups; SO3M group, COOM group (M is H, Li, Na or K) and OH 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.

    Abstract: PURPOSE:The titled composition that is made by adding cationized keratin derivative to hair cosmetics other than preshampoo treatment, thus showing good affinity to hair and skins, giving hairs flexibility, wiriness and moistness with high detergency. CONSTITUTION:Hair cosmetics other than preshampoo treatment are combined with a cationized keratin derivative that is obtained by reaction of all or a part of the sulfhydryo groups in keratin with a cationizing reagent containing the group of the formula (X is halogen) and a quaternary nitrogen in the molecule such as S-(beta-hydroxy-gamma-trimethylammoniopropyl)keratin. The above keratin is prepared by subjecting a keratin substance such as wool or hair to reductive treatment. As the above cationizing reagent, is most usually glycidyltrimethylammonium chloride.
