Abstract: A printing material containing a white layer and an absorption layer formed on a base material made of a resin film. The base material may be black and opaque, while the white layer contains titanium oxide. The absorption layer may contain a protein and absorbs aqueous inks. The white layer is hydrophilic and thus highly compatible with aqueous inks which have permeated the absorption layer and reached the white layer, thereby giving a vivid image. The printing material may be used in an advertising poster adhered to a windowpane of a bus, etc. by forming a number of holes in the printing material.

Abstract: A sphingoglycolipid represented by the following formula: obtained from a bacterium of the genus Sphingomonas, further from the species paucimobilis, capsulate or adhaesiva, after being washed with acetone and then extracted with alcohol or alcohol-water mixture. R1 represents a sugar portion of a single uronic acid or one to four hexoses of uronic acid, glucosamine, galactose and/or mannose; R2 represents an alkyl group which may have a cycloalkyl group, an alkenyl group or an alkynyl group; and R3 represents an alkyl group.

Abstract: A printing material 10 wherein a white layer 2 and an absorption layer 3 are formed in this order on a base material 1 made of a resin film. The base material 1 has been made black and opaque, while the white layer contains titanium oxide so as to make it white and opaque. The absorption layer 3 contains a protein and absorbs aqueous inks. Because of containing a hydrophilic and water-resistant binder resin, the white layer 2 is highly compatible with aqueous inks which have permeated the absorption layer 3 and reached the white layer 2, thereby giving a vivid image.

Abstract: A heat-resistant film includes a film substrate and a heat-resistant slip layer. The heat-resistant slip layer is disposed on one surface of the film substrate and contains a binder and a slip additive, which is a higher fatty acid metal salt composition containing a free higher fatty acid in an amount of 3 to 30 wt % and a metal salt of a higher fatty acid. With this heat-resistant film, a good heat-resistivity and slipperiness are obtained even when the slip additive is contained in the heat-resistant slip layer in relatively small amounts. The slip additive improves the solution stability of the coating composition used to form the heat-resistant slip layer. Preferably, the free higher fatty acid is stearic acid and the metal salt of higher fatty acid is aluminum stearate.

Abstract: The present application discloses an external composition for skin comprising a component obtaind by washing a bacterium of the genus Sphingomonas with acetone and then extracting the resultant with alcohol or alcohol-water mixture; an external composition for skin comprising a component extracted from a white bacterium of the genus Sphingomonas; and an external composition for skin comprising a sphingoglycolipid represented by the following formula: where, R1 represents a sugar portion consisting of a single uronic acid or one to four hexoses selected from a group consisting of uronic acid, glucosamine, galactose and mannose; R2 represents an alkyl group which may have a cycloalkyl group, an alkenyl group or an alkynyl group; and R3 represents an alkyl group; these alkyl, alkenyl and alkynyl groups being straight or branched, and substituted or unsubstituted. These external compositions for skin exhibit excellent moisturizing and skin roughnes prevention effects.

Abstract: A semiconductive rubber roller used in a printer of a photocopying machine, which is an elongated integral body consisting of a shaft of a metal, a semiconductive foamed rubber layer on and around the shaft and a semiconductive solid, i.e. non-foamed, silicone rubber layer on and around the foamed rubber layer. Unexpected improvements can be obtained in the performance and durability of the roller when the silicone rubber forming the solid silicone rubber layer contains low molecular weight organopolysiloxane molecules having a degree of polymerization not exceeding 20 in an amount not exceeding 1.0% by weight and by providing the surface of the semiconductive solid silicone rubber layer with a covering layer which may be a coating layer of a resinous coating composition or a skin layer having a modified nature by a chemical or physical treatment such as ultraviolet irradiation.

Abstract: A backprinting recording medium includes a transparent substrate, an ink-absorbing layer formed on the transparent substrate and a porous ink-permeable layer formed on the ink-absorbing layer and produced by dispersing a filler in a binder resin, wherein the binder resin constituting the ink-permeable layer has a glass transition temperature of 10° C. or higher, and a Shore D hardness at 25° C. of 40 or higher.

Abstract: It is an object of the present invention to provide a recording sheet which can produce colorful printed images of high quality without causing either problem of repelling of ink even in multicolor printing or blurring in the printed images with the lapse of time, and which can also confer high phototransmission on the printed images so that it is well suitable for a transparency for OHP. A recording sheet having an ink-receiving layer formed on at least one surface of a substrate is disclosed, wherein said ink-receiving layer is formed by applying a resin solution comprising (a) a resin containing (1) a component presenting water-solubility in its molecules and (2) a component containing a functional group forming a crosslinking point in its molecules and presenting water-solubility before a crosslinking point is formed, and (b) a water-soluble resin on the substrate, and thereafter forming a crosslinking point.

Abstract: A recording sheet has a base and a receptive layer disposed on at least one surface of the base. The receptive layer contains at least a water-absorbent copolymer and said water-resistant graft copolymer whose main chain is polyvinyl alcohol. The water-absorbent copolymer absorbs inks, and the water-resistant graft copolymer makes the receptive layer resistant to discoloration, blurring, and gloss or luster irregularities. The water-absorbent graft copolymer comprises a graft copolymer produced by grafting a vinyl monomer having a carboxyl group and a monomer having a functional group reacting with the carboxyl group. The water-absorbent copolymer comprises a copolymer of acrylic acid and vinyl alcohol. The water-resistant graft copolymer and the water-absorbent copolymer are added at a ratio in parts by weight ranging from 20/80 to 80/20, preferably, from 30/70 to 70/30.
