摘要： PURPOSE:To obtain a print having a high grade by forming a transparent coating layer mainly comprising amorhpous silica and/or kaolin, mean grain size of which is brought to specific values or less respectively, and adhesives onto the surface of a transparent synthetic resin sheet. CONSTITUTION:A transparent coating layer mainly comprising amorphous silica or kaolin is formed onto the surface of a transparent synthetic resin sheet, and a printed layer is shaped onto the coating layer so as to able to appreciate through the sheet. Amorphous silica having mean grain size of 0.5mum or less and/or kaolin having mean grain size of 0.5mum or less is used as a pigment employed for the coating layer. When mean grain size is larger than 0.5mum, transmitted light is scattered remarkably, and desired transparency is not acquired. An ionizing radiation cured resin composition such as polyvinyl alcohol having excellent transparency or modified polyvinyl alcohol and/or unsaturated polyester is favorable as an adhesive component for the transparent coating layer.

摘要： PURPOSE:To extremely reduce a lowering of whiteness and recording density even during preservation under a high temp. condition by using 3-di(n-butyl) amino-6-methyl-7-phenylaminofluorane as a basic dye and also using 4- hydroxy-4'-isopropoxydiphenylsulfone and/or 4,4'-dihydroxydiphenylsulfone as a coupler. CONSTITUTION:A specific basic dye and a specific coupler are used in combination. The use ratio of both of them is desirably set so that the coupler is 100-500 pts.wt., pref. 150-300 pts.wt. per 100 pts.wt. of the basic dye. As the basic dye, 3-di(n-butyl)amino-6-methyl-7-phenylaminofluorane is used and, as the coupler, 4-hydroxy-4'-isopropoxydiphenylsulfone and/or 4,4'-dihydroxydiphenylsulfone is used. By this method, even when a heat-meltable substance is used together as a sensitizer, a lowering of whiteness due to developed color fog at high temp. is extremely reduced.

摘要： PURPOSE:To obtain a favorable thermal recording material free from the occurrence of unevenness of recording density caused by irregularities on a cloth surface by a method wherein a substrate is a woven cloth made of a yarn having a fiber diameter of a specific value or less, and a thermal recording layer is provided on the substrate. CONSTITUTION:A substrate of a thermal recording material is a woven cloth made of a yarn having a fiber diameter of 200mum or less, and a thermal recording layer is provided either or both surfaces of the substrate. The use of a yarn having a fiber diameter more than 200mum forms irregularities on the surface of the woven cloth and results in deterioration of printing quality. If a large amount of an undercoat layer is applied for preventing said deterioration, the intrinsic flexibility of a woven cloth is lost. A smaller fiber diameter realizes a higher image quality, but the use of a yarn of a very small fiber diameter results in a high cost. Thus, a yarn of the order of 5-100mum is most preferably used. For holding the uniformity of a recorded image or preventing a creeping of a coated layer and a pin hole, it is preferable that two or more primary yarns having a fiber diameter of 100mum or less are twisted to make a secondary yarn, and a woven cloth using the secondary yarns arranged in parallel as warps and/or woods is used as the substrate.

摘要： PURPOSE:To conduct a fine grinding by a sand mill with an improved efficiency by incorporating a specific polyvinyl alcohol and at least one of methyl celluloses in a water dispersion of an organic solid substance. CONSTITUTION:In the wet fine grinding of a water dispersion of an organic solid substance by a sand mill, a polyvinyl alcohol which forms a 0.1% water solution at 20 deg.C having a surface tension of 63dyne/cm or less and has a polymerization degree of 500 or more and at least one of methyl celluloses are incorporated in said organic solid substance water dispersion. The specific polyvinyl alcohol is preferably added in the range of 0.2 - 10pts.wt. per 100pts.wt. of the organic solid substance, and especially the addition amount ranging 1.0 - 5pts.wt. is preferable. On the other hand, the methyl celluloses to be used in combination is desirably added in the range of 0.05 - 50pts.wt. per 1pts.wt. of the specific polyvinyl alcohol, and particularly the addition amount ranging 0.5 - 5pts.wt. is suitable.

摘要： PURPOSE:To enable stable recording free of a fogging or blocking phenomenon by incorporating hyaluronic acid or a salt thereof in at least one of the layers constituting a recording material. CONSTITUTION:Hyaluronic acid or a salt thereof is incorporated in at least one of layers constituting a recording material, in a thermal recording material which comprises a recording layer comprising a colorless or light-colored basic dye and a color reaction agent for developing the basic dye into a color when being heated. Of the hyaluronic acid (or the salt thereof), one which has a molecular weight of 2X10 to 8X10 , most preferably 3.5X10 to 2X10 , is free of possibility of thinking of a coating liquid containing the hyaluronic acid, and provides an excellent antistatic effect, so that it can be used preferably. It is particularly effective for the hyaluronic acid or salt thereof to be incorporated in a backing layer of a support. The amount of the hyaluronic acid (or salt thereof) used is generally 0.1-5g/m , preferably 0.2-2g/m .

摘要： PURPOSE:To prevent the adhesion of refuse to a head by providing a thermal recoding layer comprising a specified heat-fusible substance, a wax, a lubricant, an oil-absorptive pigment and a color reaction agent on a support to form a thermal recording material. CONSTITUTION:In addition to a colorless or light-colored basic dye and a color reaction agent capable of coloration upon contact with the dye, a heat-fusible substance showing a weight loss of at least 5% at 200 deg.C under the temperature rise rate condition of 20K/min, wax, a lubricant and an oil-absorptive pigment having an oil absorption of at least 85cc/100g are dispersed by an agitating and grinding machine such as a ball mill and a sand mill by using water as a dispersant to prepare a coating liquid. The coating liquid is applied to a support, and is dried to provide a thermal recording layer, thereby obtaining a thermal recording material. The wax is preferably used in an amount of 3-100pts.wt. per 100pts.wt. of the heat-fusible substance.
