Embodiment 1

[0135] 12.0 parts of a compound represented by the following formula (II-1), 60.0 parts of N-methyl-2-pyrrolidone, and 12.6 parts of piperidine (manufactured by Tokyo Chemical Industry Co., Ltd.) were mixed, and the resulting mixture was stirred at 60°C for 5 Hour. After cooling the said reaction liquid to room temperature, it added to the liquid mixture of 600 parts of water and 100 parts of 35% hydrochloric acid, and stirred at room temperature for 1 hour. The precipitated crystals were collected as suction-filtered residues and dried to obtain 12.4 parts of the compound represented by the formula (I-1). The yield was 83%.

Abstract

The invention provides a compound represented by formula(I). In the formula(I), R1 and R2 represent hydrogen atoms or alkyl groups respectively and independently, R3 represents -SO3, -SO3-M+, -CO2H or -CO2-M+. M+ represents (R11)4N+,Na+ or K+, R11 represents hydrogen atom, alkyl group or aralkyl, R4 represents alkyl group, alkoxy, hydroxy, cyanogroup or nitro, m represent an integer between 0 and 2, n represent an integer between 0 and 3, and p represent an integer between 0 and 3.

Description

technical field [0001] The present invention relates to compounds for use in dyes. Background technique [0002] Dyes are used for displaying colors using reflected light or transmitted light in fields such as fiber materials, liquid crystal display devices, inkjet, and the like. As such a dye, rhodamine B represented by the following formula (a) having a xanthene skeleton is widely known (P. 274 of "Shin Dye Chemistry" 1st edition by Toyoto Hosoda, May 1973 (Co., Ltd.) newspaper). [0003] [0004] The above-mentioned compounds conventionally known do not necessarily satisfy solubility in organic solvents sufficiently. Contents of the invention [0005] The present invention includes inventions described in the following [1] to [10]. [0006] [1] The compound for coloring compositions represented by formula (I). [0007] Formula (I): [0008] [0009] [Formula (I), [0010] R 1 and R 2 Each independently represents a hydrogen atom or an alkyl group having 1 ...
