[0193]

[0194] 4.93 g (0.03 mol) of 3-amino-5-tert-butyl-2H-pyrazole-4-carbonitrile were dissolved in a mixture of acetic acid (6 ml), propionic acid (10 ml) and concentrated hydrochloric acid (10 ml), and It was cooled to 0 °C. To this solution, 2.07 g (0.03 mol) of sodium nitrite was added dropwise at an internal temperature of 5°C or lower. Then stir for 15 min at an internal temperature of 0-5°C. Overlapping solutions are thus prepared. Separately, 5.34 g (0.03 mol) of 6-tert-butyl-3-methyl-1H-pyrazole[5.1-c][1.2.4]triazole were dispersed in 90 ml of acetonitrile, which was then cooled to an internal temperature of 5°C. Into the obtained dispersion liquid, the previously prepared overlapping solution was added dropwise at an internal temperature of 5°C or lower. Then it was stirred at 5° C. for 1 h and at room temperature for 30 min, and 100 ml of water was added dropwise theret...

Abstract

The present invention relates to an azo dye represented by a formula (1), a colored composition, a heat-sensitive transfer recording ink sheet, a heat-sensitive transfer recording method and a color filter, wherein R<11> represents a monovalent substituent, R<12> represents a hydrogen atom or a monovalent substituent, Ar<1> represents a specific heterocyclic group such as a group such as a group shown below, and X represents atoms necessary to form a ring; wherein, in the heterocyclic group, R<61> to R<63> each independently represents a hydrogen atom or a substituent.

Description

technical field [0001] The present invention relates to a special novel azo dye and a coloring composition including the azo dye, a thermal transfer recording ink sheet, a thermal transfer recording method, a color toner, an ink for inkjet, and a color Color filters, all of which contain this azo dye. Background technique [0002] In recent years, especially materials for forming color images have been mainly used as image recording materials. More specifically, recording materials for inkjet systems, recording materials for thermal transfer systems, recording materials for electrophotographic systems, silver halide photosensitive materials for transfer systems, printing inks, stylus pens, etc. have been commonly used. Color filters are used in image capture devices such as CCDs in photographic equipment, and displays such as LCDs and PDPs to record and reproduce color images. [0003] In these color image recording materials and color filters, ternary color colorants (dye...
