摘要： PURPOSE:To improve the storage stability of recording, a developed color phase and sensitivity by providing a color forming layer containing specific aromatic isocyanate and a specific imino compd. as color formers on a support. CONSTITUTION:Aromatic isocyanate represented by formula I and an imino compd. represented by formula II are dispersed in a medium not dissolving both compds along with a binder such as polyvinyl alcohol to be mixed or ground to prepare a dispersion. This dispersion is applied to a support such as paper or a plastic film and dried to form a thermal layer to obtain a thermal recording sheet. As a concrete example of aromatic isocyanate represented by the formula I, 4',4''-diisocyanate-2,5-dimethoxytriphenylamine is designated. As a concrete example of the imino compd. represented by the formula II, 3-iminoisoindolin-1-one or 3-imino-4,5,6,7-tetrachloroisoindolin-1-one is designated.

摘要： PURPOSE:To manufacture a high-quality printing in which a clear image free from a blur and collapse is reproduced, by a method wherein a platen comprised of the nontransferrable quality of the material to a heat-sensitive recording layer is provided into an image forming device. CONSTITUTION:A film of a transfer body to be fed through a transfer body roll 1 is led to an image forming part which is constituted of a platen roll 2 and thermal printing head 3, information which is to be printed is applied to the head 3 by a normal way while contacting the roll 2 with a heat-sensitive recording layer of a film surface and contacting the rear with the head 3 and the roll is turned while aligning with output and an image is formed by moving the film in an auxiliary scanning direction. Then the image is reproduced on the surface of paper by leading an image transfer part constituted of a pressure- contacting roll 5 while the paper to be fed through a transferred body roll 4 is being confronted with the heat-sensitive recording layer of the film surface. Since the roll 2 is comprised of the nontransferrable quality of the material to a heat-sensitive recording layer, the image to the heat-sensitive recording layer has excellent resolving properties.

摘要： PURPOSE:To color a wide range of materials, e.g. glass, by bringing a compound containing an imino group into contact with a blocked isocyanate and isocyanate generator under heating, and forming a colored substance in the vehicular phase. CONSTITUTION:(A) A compound containing one or more imino groups of formulaI{A is O,NH or (OR)n[R is lower alkyl; (n) is 1 or 2]; Z is aromatic or heterocyclic ring capable of forming a conjugated system with formula II}, e.g. 3-iminoisoindolin-1-one, (B) a blocked isocyanate of formula III[R1 is aromatic compound residue; R' is isocyanate blocked compound residue having active hydrogen atoms; (m) is an integer 1-4]and/or (C) an isocyanate generator are dispersed in a vehicle, and the resultant dispersion is applied to a substrate to form a coloring phase thereon. The resultant formed coloring phase is then heated by a heating element, etc. to color and produce an image.

摘要： PURPOSE:To simply and economically obtain an isoindolinone pigment in high purity having fresh color tone by heating an isoindolinone in the presence of hydrophobic organic solvent, water and alkaline(earth)metal hydroxide. CONSTITUTION:A compound represented by the formula, wherein X is a halogen atom, n 1-4, and R aromatic diamine residue or heterocyclic diamine residue, is heated at 70-120 deg.C, preferably at 80-105 deg.C, in the coexistence of hydrophobic organic solvent and water in the presence of alkaline(earth)metal hydroxide. After heating, organic solvent is removed therefrom by steam distillation or the like, filtration and rinsing are repeated, or nutralized by acid as required, to thereby remove alkali content and water-soluble impurities, etc. and purified fine isoindolinone is recovered.
