Abstract: NEW MATERIAL:A 4-substituted carbonylcoumarin compound of formula I, wherein R1 and R2 are each H, alkyl, alkoxyalkyl, etc.; R3 is H, alkyl, alkoxyalkyl, etc.; R4 and R5 are each H, alkyl, alkoxyalkyl, etc.; X is H, alkyl or cycloalkyl; and Y is H, alkylcarbonyl, alkoxycarbonyl, etc. USE:A photopolymerizable resin composition comprising a photosensitive resin, a photopolymerization initiator, and a photosensitizer, wherein a 4-substituted carbonylcoumarin compound of formula I is used as the photosensitizer. A resin composition which gives a photosensitive coating film excellent in sensitivity and long-term stability can thus be obtained. PREPARATION:A 4-substituted aminosalicylaldehyde of formula II is made to react with a cyanomethyl-substituted derivative to give a compound of formula III, which is boiled in dilute hydrochloric acid to give a compound of formula IV. The compound of formula IV is then reacted with NaCN, and bromine is added thereto to give a cyano compound of formula V. The cyano compound is heated in the presence of sulfuric acid to give an objective compound of formula I.

Abstract: PURPOSE:To control sublimable transfer amount of dye and to facilitate gradation recording by altering energy to be applied to a heat sensitive head at the time of heat transfer by using specific anthraquinone cyan dye. CONSTITUTION:The quantity of sublimation starting heat has no correlation directly to molecular weight itself, but relates to mutual action among colorant molecules and to mutual action between dye molecules and ink binder resin. Even if the molecular weight of the dye is slightly increased, the dye having satisfactory solubility to ink solvent and lower melting point is desired, and the dye having mutual action to the binder resin for ink to be small in the degree not lose preservation stability after a ribbon is manufactured is most desirable. Dye represented by a formula (I) exceeds 400 of molecular weight, but obtains relatively desirable sublimating speed. In the formula, R1 is alkoxycarbonylalkyl group, alkylcarbonylalkyl group having normal chain or branch, R2 is hydrogen atom, lower alkyl group, alkoxy group, alkenyl group, trifluoromethyl group, having normal chain or branch, halogen atom.

Abstract: PURPOSE:To facilitate gradational recording and provide suitability for full-color recording, by using a specified anthrequinone cyan coloring matter, and controlling the quantity of the coloring matter transferred through sublimation by regulating the energy supplied to a thermal head at the time of thermal transfer. CONSTITUTION:An anthraquinone coloring matter for sublimation transfer recording of the formula, produced by esterifying a 1-substd. amino-4- bromoanthraquinone-2-carboxylic acid through an acid chloride and condensing the resultant ester with an aniline acid by the conventional method is mixed with a resin, a solvent or the like to prepare a recording ink, which is applied to e base to obtain a transfer sheet. The sheet is superposed on a recording material, and heat and pressure are applied by a thermal recording head from the back side of the sheet, whereby the coloring matter on the sheet is transferred onto the recording material. In the formula, each of R1 and R2, which may be the same or independent from each other, is a straight chain or branched lower alkyl, cycloalkyl, alkenyl, aryl, aralkyl or alkoxyalkyl, and each of R3, R4 and R5, which are the same or independent from each other, is hydrogen, a straight chain or branched lower alkyl, alkoxyl or alkenyl.

Abstract: PURPOSE:To obtain a stable magenta color by incorporating specified 2 kinds of dyes alone or in a mixture. CONSTITUTION:A binder resin contains the yellowish red dye of formula I and the bluish red dye of formula II alone or in a mixture to form the magenta color. An amount of each dye for the magenta color toner is, preferably, about 0.1-10wt.%. In formulae I and II, X is O or S, each of R1-R3 is alkyl, alkoxy, alkoxyalkoxy, hydroxy, or halogen, thus permitting a fog-free sharp magenta color image to be obtained.
