摘要： PURPOSE:To enhance sensitivity and to reduce image fog by forming an electric charge generating layer containing a phthalocyanine compound and a charge transfer layer containing a specified hydrazone compound in a photosensitive layer to be formed on a conductive supporting body. CONSTITUTION:The electrophotographic sensitive body is provided with the charge generating layer of 0.01-5mmu film thickness containing the phthalocyanine compound and the charge transfer layer containing one of the hydrazone compounds represented by formula I in which each of R1-R4 is optionally substituted alkyl or aryl group; R5 is H, halogen atom, optionally substituted alkyl, alkoxy, optionally substituted aryloxy, such acyl, or substituted amino group; and (m) is an integer of 1-4, thus permitting the obtained photosensitive body to be superior in sensitivity and to form an image small in fog.

摘要： PURPOSE:To obtain a thermal recording sheet having excellent picture storability and a purple-colorable hue by providing a color-forming layer containing a specific aromatic isocyanate and a specific imino compound for a supporter. CONSTITUTION:A color-forming layer contianing an aromatic isocyanate of the formula (I) as a color-forming agent and an imino compound of the formula (II) is provided to a supporter. In the formula (II), X is a halogen atom, (n) is an integer of 0-4, and A is C=0 or C=NH. As the supporter used, besides papers to be used in general, synthetic resin films, laminate papers, nonwoven fabrics, etc., may be used according to purposes. The color-forming layer is formed by dispersing a color-forming agent in an aqueous solution and/or aque ous dispersion of adequate binder, coating the solution or dispersion on the supporter, and drying it.

摘要： PURPOSE:To form a colored or color-formed image excellent in the chemical resistance and the photoresistance by using a specified body to be colored. CONSTITUTION:A colored image is formed on a body to be colored by causing a contact reaction between an imino compound (a color forming agent A) as shown by the formula I and and an aromatic amino compound or a hydrazine compound (a color forming agent B) by heating. In the color formation mechanism, an azomethine color formation by a reaction between imino group >C=N of an imino compound as specified, amino group -NH2 of an amino compound or -NHNH2 group of a hydrazine compound is achieved very easily by the supply of heat energy. The formation of various colors such as red, orange, yellow and black is possible by selecting the color forming agent A and the color forming agent B properly. The photoresistance of a colored matter thus obtained is very excellent.

摘要： PURPOSE:To make it impossible to forge bills, by adding a coloring agent and a color developer to a binder contg. a compd. to be polymerized and hardened by light, and a photopolymn. initiator, causing reaction coloration by pressing or heating it, and projection light to harden and fix the colored material. CONSTITUTION:An acidic color developer, such as bisphenol, and a colorless dye or the like for reacting with acid and coloring are microencapsulated, respectively, separated from each other. Such >=2 components which develop color when they contact with each other and react, and each 1s separately dispersed together with a compd. to be hardened by photopolymn., such as trimethylolpropane acrylate, and a photopolymn. initiator, such as benzoin methyl ether into a thermoplastic resin, such as polystyrene. Two sheets are coated with each of these 2 dispersions, and the coated faces are brought into contact, or one sheet is coated with them in 2 layers to form a thermosensitive or pressure sensitive coloring material. This material is reacted to develope by writing letters or the like with a thermal heat or a ball pen on the material, and then, it is exposed to light of a high pressure mercury arc lamp or the like to harden it, thus permitting fixation of a colored material suitable for an unforgeable record, such as bills or bonds, to be executed because said 2 components of the coloring agent and the color developer cannot be moved by heating or pressing again afte the hardening.
