Abstract: PURPOSE:To enhance heat-resistance, light-resistance, sublimation speed, hue, ribbon stability, and the like, by using an anthraquinone dye of Cyan shown by a specific formula as a dye for sublimation-transfer recording. CONSTITUTION:An anthraquinone dye for sublimation-transfer recording is synthesized by employing a normal method in which 1,5-dichloro-4,8- dihydroxyanthraquinone as a raw material is condensed with anilines. This anthraquinone dye is shown by a formula I (a benzene nucleus A represents one or more alkyl, alkoxy, hydroxyl, trifluoromethyl, alkoxyalkyl, hydroxyalkyl, carbonyl, carboxy, and phenyl groups, which may be the same or independent). This dye is enhanced in solubility to organic solvent and dispersibility to water and capable of easily preparing a high-density ink.

Abstract: PURPOSE:To obtain an image of a sharp yellow color free from fog and good light resistance by incorporating a specified pyridone type dye in a binder resin. CONSTITUTION:The binder resin contains one of the pyridone type dye represented by formula I in which each of R1 and R2 is H, halogen, alkyl, or alkoxy; and R3 is alkyl, alkoxyalkyl, or aralkyl. The addition amount of said dye is controlled in accordance with the electrostatic chargeability of the binder resin, or those of a colorant and additives auxiliary added, compatibility with the resin, dispersion process, and the like, but in general it is preferred to use the dye in an amount of 0.1-10wt.%.

Abstract: PURPOSE:To provide the title coloring matter excellent in fastness, giving good dyeability and color developability in carrying out, in particular, recording through sublimation transfer by heating with thermal head, consisting of an anthraquinone-based red coloring matter. CONSTITUTION:The objective anthraquinone-based red coloring matter for heat-sensitive sublimation transfer of the formula (R and R are each H, 1-4C alkyl, 1-4C alkoxy, or halogen, but when either R or R is H, the other is not H). This coloring matter is incorporated with a resin (e.g. rosin-, phenol-base one) and a solvent (e.g. an alcohol, cellosolve, ketone) to prepare a recording ink, a condenser paper or glassine paper being coated with this ink to form a transfer sheet. The use of this transfer sheet will avoid thermal decomposition during transfer recording, leading to extremely highly reliable record storage because of excellent light resistance of said sheet.

Abstract: PURPOSE:To enable control of the quantity of a coloring matter transferred through sublimation at the time of thermal transfer and facilitate easy gradational recording, by synthesizing a 1,4-diamino-2-phenoxyanthraquinone magenta coloring matter of a specified general formula. CONSTITUTION:1,4-Diemino-2-chloroanthraquinone is brought into reaction with a meta-substd. phenol of formula I (R is an alkyl, alkoxyl, hydroxyl or halogen) in a polar organic solvent, such as sulfolane, in the presence of a base. By the reaction, a magenta coloring matter for thermal sublimation transfer of formula II (R is is the same as that in formula I) can be obtained. A thermal transfer recording ink can be prepared by use of the coloring matter by mixing the coloring matter with an appropriate resin, solvent or the like.

Abstract: PURPOSE:To obtain a colored liquid crystal material or a colored organic polymeric material having high solvent stability, high compatibility with binder and high stability against heat and light by coloring the liquid crystal material or the organic polymeric material with a quinophthalone compound having a specified chemical structure. CONSTITUTION:A quinophthalone compound (hereinbelow referred to as a colorant) represented by the formula (wherein R1 is a H, 8 C or lower (branched) alkyl or cycloalkyl; R2 is H, a halogen, a (substituted) alkoxy, alkylthio or (substituted) arylthio; R3 is H or am (un)substituted heterocyclic ring having at least two N, O or S atoms) is used. To produce a liquid crystal composition by using this colorant, the colorant is dissolved in a suitable liquid crystal compound and is sealed in a liquid crystal cell of a thickness of about 10mum pretreated so as to be homogeneously oriented. The amount of the colorant added is about 1.0-3.0-wt.%. To color a resin, the colorant is dissolved in a suitable synthetic resin, and the mixture is molded into any desired shape. A suitable dyeing bath may be used. The amount of the colorant added is 0.01-5wt.%.

Abstract: PURPOSE:To prepare an ink compsn. for thermal transfer recording having a high sublimation speed by compounding an yellow sublimable dye represented by a specific general formula, a binder resin and an org. solvent and/or water. CONSTITUTION:A phthalimide compd. represented by formula I (wherein R1 is H, an alkyl group, a cycloalkyl group, an alkoxyalkyl group or a halogenoalkyl group) is diazotized and subsequently coupled with a pyridone compd. represented by formula II (wherein R2 is same to R1 of the formula I) to synthesize a dye for thermal transfer recording represented by formula III (wherein R1 and R2 are same as the formulae I, II). This dye for thermal transfer recording and a binder resin are dispersed in an org. solvent and/or water to prepare an ink compsn. which is, in turn, applied to one surface of a base material sheet and dried to form a dye support layer to obtain a transfer sheet. As a concrete example of a resin for preparing the ink compsn., a rosin or phenol type oily resin is designated.
