摘要： PURPOSE:To impart antistatic property to thermal stencil paper, to eliminate the adverse effect on a thermal head due to a conductive agent at the time of plate making and to obtain the thermal stencil paper excellent in stability with the elapse of time and feed properties by adding the conductive agent to a porous support. CONSTITUTION:Thermal stencil paper is formed by laminating a thermoplastic resin film layer to one surface of a porous support through an adhesive layer and the porous support contains a conductive agent. By adding the conductive agent to the porous support, antistatic capacity is imparted to the thermal stencil paper and the adverse effect on a thermal head due to the conductive agent at the time of plate making is eliminated and the thermal stencil paper excellent in stability with the elapse of time and feed properties can be obtained. By the presence of the antistatic agent, the hydrophilicity of the porous support and the retentivity of printing ink are enhanced and, as a result, printed matter of high quality reduced in density irregularity is obtained. By forming the adhesive layer from an adhesive consisting of a polyurethane resin and monofunctional and/or polyfunctional (meth)acrylate, the thermal stencil paper excellent in image quality and printing durability can be obtained.

摘要： PURPOSE:To obtain the hard coat film excellent in scratch resistance and abrasion resistance by a method in which a film is coated with the resin composition containing respectively specified amounts of the urethane compound into which the diol having a specified molecular weight and the compound having polymerizable unsaturated group are introduced, and the monomer having radical polymerizable unsaturated group, and then electron beam is applied to said film. CONSTITUTION:50-400pts.wt. of the monomer having at least one radical polymerizable unsaturated group in one molecular is added to 100pts.wt. of urethane acrylate oligomer obtained by combining diisocyanate and the diol having hydroxyl groups on both terminals and 200-3,000 of weight average molecular weight with the acrylate compound having two hydroxyl group and one or more radical polymerizable unsaturated group. Thus resin composition is generated. After the upper surface of a substrate film 1 has been coated with the coating liquid 3 of the resin composition by using a coating device 2, mirror surface-material 4 is laminated on the substrate film 1 by directing the surface of mirror state to said film 1.

摘要： PURPOSE:To inexpensively and easily obtain base paper capable of preventing sticking to a thermal head and developing excellent printing durability at the time of printing, by forming a resin layer from a polymerization product of a thermoplastic resin containing an addition polymerizable monomer. CONSTITUTION:In thermal stencil paper wherein a thermoplastic resin layer 2 is laminated to one surface of a support 1, the resin layer 2 is composed of a polymerization product of a thermoplastic resin containing an addition prolymerizable monomer. The thermoplastic resin layer 2 containing the addition polymerizable monomer is formed to the surface of a surface smooth film 3 and the porous support 1 is laminated to the surface of the resin layer 2 and, after the polymerization of the monomer, the surface smooth film 3 is released to prepare thermal stencil paper. The addition polymerizable monomer is pref. used in a ratio of about 5-30pts.wt. per 100pts.wt. of the thermoplastic resin and, when the amount of the monomer is below the range of about 5-30pts.wt., it is difficult to achieve the purpose and, when said amount exceeds said range, the thermal perforation of the resin layer is lowered. The support can be sufficiently bonded to the thermoplastic resin layer and the sticking to the thermal head is prevented by adding a surfactant to make it possible to omit the formation of a sticking preventing layer.

摘要： PROBLEM TO BE SOLVED: To prevent foreign substance from adhering to transparent base surface through static electricity, and prevent harming of transparency by scratches generated through friction, by constructing a film from transparent base film, a transparent conductive layer provided on the base film, and a hard coated layer provided on the transparent conductive layer. SOLUTION: An antistatic hard coated film 5 is composed of transparent base film 1, a transparent conductive layer 2 provided on the base film 1, and a hard coated layer 3 provided on the transparent conductive layer 2. The surface resistivity of the transparent conductive layer 2 is 10 Ω/(square) or lower. If the surface resistivity of the transparent conductive layer 2 is over 10 Ω/(square), good antistatic effect is not developed. The hard coated layer 3 is composed of an anisotropic conductive layer, and is formed on the transparent conductive layer 2 by applying a layer, which has excellent resistance to marring, and does not greatly harm conductivity. Reactive hardening resin composition, which strongly bonds to the transparent conductive layer 2, can be used.

摘要： PROBLEM TO BE SOLVED: To cost effectively obtain an antireflection film of which the low- refractive index layer has an excellent adhesion property to a high refractive index hard coating layer without using costly and intricate equipment, etc., by forming the high-refractive index hard coating layer of the antireflection film as a specific gel film. SOLUTION: The high-refractive index layer of the antireflection film constituted by laminating the hard coating layer 2 having a high refractive index and the low-refractive index layer 3 on a transparent base material film 1 is composed of the gel film which is formed from a sol liquid contg. the oxide sol of titanium or tantalum and a reactive org. silicon compd. in a liquid medium and has a refractive index of >=1.65. Any films are usable as the transparent base material film, insofar as the films have transparency. Uniaxially or biaxially stretched polyester is used adequately in terms of excellent transparency and heat resistance and absence of optical anisotropy. The metal oxide sol of the titanium or tantalum is preferably formed by hydrolyzing the respective metal alkoxides.

摘要： PURPOSE: To provide a high battery characteristic by enhancing utilization efficiency of an active material. CONSTITUTION: In an electrode plate constituted by forming a powdery active material and an applying layer formed by containing a conductive material and a binding agent in a collector unit, an active material grain has a rigid frame-shaped structure formed with a stratified crack. A slurry-state active material-contained mixture, formed by mixing a powdery active material and a powdery conductive material and binding agent in a prescribed solvent, is prepared to apply this active material-contained mixture to the collector unit. Next the solvent is removed from this object, to form an active material- contained mixture coating on the collector unit. Relating to an active material, pressure processing is applied before preparing the active material-contained mixture or after forming the coating, to form a fine stratified crack in a surface of the active material grain.
