The component (a) an insoluble egg-shell membrane fine powder with a mean particle size of 0.1 to 10 ?m while the component (b) is a synthetic resin emulsion or a synthetic resin solution.

Abstract: The modifying powder is silk powder having an average particle diameter of 10 ?m or less, oil absorption of 130 ml/100 g or less and particle diameter of 80 ?m or less on the basis of dispersion degree evaluation with a grind gauge according to JIS K5400; or polysaccharide powder having an average particle diameter of 10 ?m or less, and ink viscosity of less than 15 Pa·s or oil absorption of 85 ml/100 g or less. Such modifying powders can be obtained through a method comprising a first pulverization process for pulverizing a starting material for modifying material using a dry-type mechanical pulverizer such as a ball mill, and a second pulverization process for pulverizing the obtained pulverized product with a jet mill to fine particles having an average particle diameter of 10 ?m or less, wherein pulverization treatment time in the first pulverization process is determined to be 40 hours or more.

Abstract: A ultraviolet-curable coating agent contains: a hydrophilic polymer having the specific structure represented by the following general formula (1); a polymerization-reactive urethane oligomer; a water-soluble monomer; a photo polymerization initiator; and a water-absorptive filler. The polymerization-reactive urethane oligomer is preferably formed of a carboxyl-group-containing dihydroxyl compound, polymer polyol, organic diisocyanate compound and hydroxyl-group-containing acrylic ester, and a number average molecular weight of the polymerization-reactive urethane oligomer is preferably 1000 to 10000. By applying the ultraviolet-curable coating agent onto a front face of a substrate, an ink-receiving layer having excellent ink absorptivity, drying characteristics of printed images, bleeding resistance, anti-tacking and water resistance can be formed.

Abstract: A cross-linked fiber is provided by cross-linking a fiber made of polyglutamic acid sodium of molecular weight of 200,000 or more and a polymer cross-linking agent. The polymer cross-linking agent is preferably a polymer having an oxazoline group or a polymer having an epoxy group. The cross-linked fiber is manufactured by: spinning threads from a solution in which the material is mixed by an electrostatic spinning to form a fiber and a fiber assembly; and heating the fiber and the fiber assembly to form the cross-linked fiber.

Abstract: A fiber containing an eggshell membrane component. The fiber is produced by spinning using a solution containing the eggshell membrane component by employing an electrospinning method. A fiber assembly formed from the fiber obtained by employing the electrospinning method imitates a natural eggshell membrane, whereby sufficient air permeability is exhibited. Since the fiber assembly is also excellent in adherence to skin tissue of a human body and stypticity, the fiber assembly may be preferably used as a wound dressing or a cosmetic sheet.

Abstract: A fiber treatment agent contains components (a) and (b). A fiber treated with the fiber treatment agent and a fiber fabric including the fiber are also provided. The component (a) an insoluble egg-shell membrane fine powder with a mean particle size of 0.1 to 10 ?m while the component (b) is a synthetic resin emulsion or a synthetic resin solution.

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: There are provided a method of manufacturing an information recording medium 1 having a water-based ink absorbing layer 2 on a surface of a base material 3, and the information recording medium 1 obtained by the manufacturing method. The method includes: (1) coating the surface of the base material with a water-based ink absorbent containing a water-absorptive filler to form a coated layer 2a; (2) covering a surface of the coated layer 2a with a cover material 10; (3) irradiating the coated layer 2a with active energy beam to cure the coated layer 2a; and (4) removing the cover material 10 from the coated layer 2a.

Abstract: A cosmetic material with an excellent feeling which contains a crosslinked product of poly-?-glutamic acid and/or a crosslinked product of a poly-?-glutamic acid salt having a particle size of 0.1 to 100 ?m and an average particle size of 1 to 50 ?m, exhibits a less stickiness upon use, a good familiarity with skin or hair, a good moisture retention effect and a good moist feeling, and is improved in various feelings such as smoothness and neat feeling.

Abstract: The present invention provides a fiber processing agent used for processing a surface of a fiber, and the fiber processing agent contains a soluble eggshell membrane and a reactive organic compound having a reactive group. With the fiber processed with the fiber processing agent having the composition as described above, even when the fiber is used for a long period of time, the eggshell membrane is not removed therefrom and the properties provided by the eggshell membrane can be maintained, so that the fiber has excellent durability and can continuously provide the moisture retention, water-absorbing property, moisture-absorbing property, antistatic property, and wound-treating property.
