Abstract: PROBLEM TO BE SOLVED: To obtain a good ink absorption property, water resistivity, and moisture proof making the ratio of glossiness of yellow, cyan, and magenta after printing relative to the glossiness of an ink receptacle layer before printing in JIS 88741, larger than a specific value. SOLUTION: The relation between the glossiness G1 of a receptacle layer before printing and the glossiness G2 of yellow, cyan, and magenta after printing is preferably to be G2/G1>=0.5 (preferably 0.6), and if it is less than 0.5, the coloring property (glossiness) of printing pictures tends to lower. In addition, each glossiness G2 of yellow, cyan, and magenta after printing is preferable to be 50% or more, and more preferably, to be 55% or more. Furthermore, the relation between the thickness d1 of a lower layer consisting mainly of a cationic copolymer and cross-linked polyalkylene oxide resin and the thickness d2 of an upper layer consisting mainly of hydrophilic polymeric resin is preferable to be d1>=d2, and as d2 exceeds d1, water resistiveness or moisture preventiveness becomes low.

Abstract: PROBLEM TO BE SOLVED: To make snow and soil be easily removable and to reduce damage, etc., of a ski board at a low temperature to make the ski board be excellent in sliding on snow, soilproof, easily washing, and weather resistance by forming an adhesive layer on a fluororesin film. SOLUTION: This protective film for a ski board is made by laminating an adhesive layer 2 on a fluororesin film 1. The reason why the fluororesin film is used is because the film has proper flexibility to make the film be easily and quickly adhered on a ski board and is hard to be adhered by snow and ice at a low temperature to slip them off. By using the fluororesin film 1 with those features as a protective film for a ski board, the serviceability and the application performance are made excellent by far. As the fluororesin film 1, undrawn ETFE film of a copolymer of tetrafluoroethylene and ethylene is especially effective by mechanical strength and flexibility. The thickness of the fluororesin film 1 is not limited, but 0.5-500 μm is preferable.

Abstract: PROBLEM TO BE SOLVED: To provide a recording sheet excellent in silicone oil and ink absorbabiity, toner fixing properties, printability and water resistance by coating the single surface of a plastic film with a recording layer based on a crosslinked polyalkylene oxide resin, colloidal silica, a hydrophilic polymeric resin and a fluorine type surfactant. SOLUTION: This recording sheet is constituted by coating at least the single surface of a plastic film with a recording layer based on a crosslinked polyalkylene oxide resin, colloidal silica, a hydrophilic polymeric resin and a fluorine type surfactant. As a recording layer coating method, there is no limit but a known method such as a gravure coating method, a reverse coating method, a die coating method or a bar coating method can be adapted. If necessary, by executing known surface treatment such as corona discharge treatment or primer treatment within air or other atmosphere before coating, coating properties are improved and the recording layer can be strongly formed on the film.

Abstract: PURPOSE:To easily read characters or marks even after a processing without being affected by the processing by a method wherein a printing is done on one surface of a base material made of a heat-resistant, water-resistant and chemical-resistant synthetic resin, and on the opposite surface to the printed surface, an heat-resistant, water-resistant and chemical-resistant adhesive is applied. CONSTITUTION:A polyester film is used as a base film, and on one surface of the film, a printing is applied. Then, in a diluted solvent of toluene/ethyl acetate, a composition, for which 60 pts.wt. of a solid component of a thermally crosslinkable acrylic resin is blended with 40 pts.wt. per solid component of titanium oxide, which is a whitening pigment, is evenly diffused, and a coating agent with a concentration of 10wt.% is prepared. Then, the coating agent is applied onto the base film by the gravure coating method, and the coated layer is dried to complete a film for a printing-receiving layer. By this method, a label with excellent heat-resistance, water-resistance and chemical-resistance can be obtained, and the label is not dyed or discolored in the process of dying of a cloth.

Abstract: PROBLEM TO BE SOLVED: To make an easy adhesion film excellent in adhesion between layers, suitability for thermal lamination of PVC, etc., by constituting a macromolecular binding agent out of modified polyester resin containing a vinyl group or of the modified polyester resin containing the vinyl group and chlorinated olefin resin. SOLUTION: An easy adhesion film is formed by providing a receptive layer containing a macromolecular binding agent, a crosslinking agent and a lubricant on one surface of a base at least. Although polyester, acrylic, polyurethane resins and the like can be used for the macromolecular binding agent, copolymer polyester resin obtained by grafting a compound having an unsaturated bond, or the copolymer polyester resin obtained by grafting the compound having the unsaturated bond, and chlorinated olefin resin obtained by chlorinating polyolefin, are used among them. The copolymer polyester resin obtained by grafting the compound having the unsaturated bond is obtained by grafting the compound having the unsaturated bond onto polyester resin containing a polar group.

Abstract: PROBLEM TO BE SOLVED: To obtain a superior ink absorption property, water resistiveness, and moisture proof by containing a cross-linked polyalkyleneoxide resin in the ink receptacle layer, and making a solubility rate in one minute of water immersion into a specific percent age or lower in a recording sheet having an ink receptacle layer provided, at least, on one surface of a base material. SOLUTION: The solubility rate of an ink receptacle layer in one minute of water immersion is required to be 50% or lower and, more preferably, to be 40% or lower and, further preferably, to be 20%. When the solubility rate exceeds 50%, print images tend to flow. Also, the receptacle layer is preferable to have a lower layer consisting mainly of a cationic copolymer and polyalkylene oxide resin and an upper layer consisting mainly of hydrophilic polymeric resin for the enhancement of a coloring property (glossiness), and the relation is preferably to be d1>=d2 between the thickness d1 of the lower layer consisting mainly of a cationic copolymer and polyalkylene oxide resin and the thickness d2 of the upper layer consisting mainly of hydrophilic resin. When d2 comes beyond d1, the water resistiveness or moisture proof lowers.
