Abstract: PURPOSE:To enhance the melting miscibility, picture sharpness and preservable stability of the toner compsn. by using a specific anthraquinone dyestuff. CONSTITUTION:The anthraquinone dye expressed by the formula I is incorporated into the color toner for developing electrostatic charge images. In the formula, R1 denotes H, alkyl, etc.; R2 denotes H, alkyl, etc.; R3 to R5 denote H, alkyl, etc. The cyan color toner is produced by melting and kneading, for example, the dyestuff expressed by the formula II with a binder (e.g. styrene/ acrylate copolymer), then pulverizing and classifying the mixture. The developer is formed by adding a charge control agent, etc., to the above-mentioned toner. The formation of the compsn. for cyan color sublimation transfer recording by dispersing the dyestuff of the formula II into the binder resin is preferable as well.

Abstract: PURPOSE:To make a sublimating transfer amount of a dye controllable to facilitate a gradation recording by using a specific anthraquinone cyan dye, and changing an energy to bed applied to a thermal head at the time of thermal transfer. CONSTITUTION:As a cyan sublimating transfer recording dye, a compound shown by a general formula (I) is used. In this construction, all requirements, such as heat resistance, light resistance, sublimating speed, hue, and ribbon stability, can be met. But, in the formula, R1 represents either straight-chain or branched lower alkyl group, cycloalkyl group, alkenyl group, aryl group, aralkyl group, and alkoxyalkyl group; and R2, R3, R4 represent hydrogen atom, either straight-chain or branched lower alkyl group, alkoxy group, and alkenyl group with the exception that all of them are the same, any of them is a hydrogen atom and the other two are the same, or two of them are hydrogen atoms.

Abstract: PURPOSE:To obtain excellent heat resistance, light resistance, sublimation rate, hue and ribbon stability, by using a specified anthraquinone coloring matter for sublimation transfer recording. CONSTITUTION:In producing a thermal transfer recording ink by mixing a coloring matter with an appropriate resin, an appropriate solvent or the like, an anthraquinone coloring matter for sublimation transfer recording of formula I is used as the coloring matter. In the formula, R is a straight chain or branched alkyl, cycloalkyl, alkenyl, aryl, aralkyl or alkoxyalkyl, the two Rs being identical. The anthraquinone coloring matter is capable of being controlled in the quantity thereof transferred through sublimation by regulating the energy supplied to a thermal head at the time of thermal transfer, so that the coloring matter enables easy tone recording, and is suitable for full-color recording.

Abstract: PURPOSE:To obtain a recording superior in preservation characteristic and enhanced in color depth, by using a specific compound as a Cyan dye for sublimation transfer recording. CONSTITUTION:An anthraquinone dye for sublimation transfer recording is shown by a formula (I). In the formula, X represents -CSO- or -COS-, R represents lower alkyl, cycloalkyl, alkenyl, aryl, or aralkyl, which can be either straight-chain or branched. The dye shown by the formula (I) can be easily produced by using the following two methods before reduction: 1-amino-4- nitroanthraquinone-2-carboxylic acid as a material is caused to directly react with a mercaptan through an acid chloride, or alternatively to react with an alcohol, a phenol, etc., to be turned into an ester once, and then an oxygen atom in the ester is substituted with a sulfur atom by a hydrogen sulfide. A thermal transfer recording ink is produced using the dye by mixing the dye with appropriate resin, solvent, etc. As a heat transfer method, the obtained ink is applied to an appropriate base to produce a transfer sheet.

Abstract: PURPOSE: To carry out the dyeing good in dyeing reproducibility and level dyeing properties by controlling the temperature, pH and time so as to afford a prescribed value or below of the ratio of reduction in weight-average molecular weight in dyeing an aliphatic polyester fiber with a disperse dye. CONSTITUTION: A polylactic acid, a copolymer of lactic acid and other hydroxycarboxylic acids, an aliphatic polyester prepared by condensing an aliphatic polyhydric alcohol with an aliphatic polybasic acid or an aliphatic copolyester obtained by condensing the polylactic acid with an aliphatic polyhydric alcohol and an aliphatic polybasic acid, etc., preferably a polymer consisting essentially of polybutylene succinate is melt spun and the resultant fiber is then drawn and heat-set to form an aliphatic polyester fiber. The dyeing is carried out by controlling the dyeing temperature within the range of 70-120 deg.C, preferably 80-100 deg.C, pH within the range of 4-9 and the dyeing time within the range of 30-120min so as to suppress the ratio of reduction in weight-average molecular weight before and after the dyeing to

Abstract: PURPOSE:To obtain a bright and transparent yellow or orange color image without fog and to obtain a copy having good light resistance by using a dye of specified compsn. for a piece-dying color toner. CONSTITUTION:The dye for a piece-dying color toner is expressed by formula, and the dye is used for the color toner. In formula, aromatic rings A and C are phenyl groups which may have substituents, an aromatic ring B is a phenylene group which may have substituents, and these substituents may couple to form naphthalene rings or quinoline rings. The color toner is obtd. by dyeing a toner resin by using the yellow or orange color dye expressed by formula and a nonion or anion dispersant. As for the auxiliaries, a nonion or anion dispersant is used. The dispersant to be used to dye the piece-dyeing color toner must be colorless or slightly colored because if the dispersant itself is colored, decoloration is not completely performed although a water-washing process or the like is included.

Abstract: PURPOSE:To obtain a bright and transparent yellow color picture image without fog and to obtain a copy having good light resistance by using a dye of specified compsn. for a post-dying yellow color toner. CONSTITUTION:The dye for a piece-dying yellow color toner is expressed by formula, and this dye is used for the color toner. In formula, R1 is a hydrogen atom or alkyl group, R2 is a hydrogen atom, alkyl group which may have substituents, cycloalkyl group, allyl group, or phenyl group which may have substituents, and Ar is a phenyl group which may have substituent. The dye can be produced by a well-known method. As for a dyeing assistant, a noion or anion dispersant is used. Further, as for the dispersant to be used to dye the post-dyeing color toner, the dispersant must be colorless or slightly colored because if the dispersant itself is colored, decoloration is not completely performed although a water-washing process or the like is included.
