Synthetic example 1

[0757] Synthesis of Synthesis Example 1 Intermediate (Compound 2)

[0758] In a round-bottomed flask equipped with a stirring device, 2.0 g (3.9 mmol) of rhodamine B (compound 1: manufactured by Wako Pure Chemical Industries, Ltd.) and 2.7 g (3.9 mmol) of tetrakis(pentafluorophenyl)boron were added. (IV) Lithium salt (LiFABA) (manufactured by Tosoh Finechem Co., Ltd.) and 30 ml of methylene chloride were reacted at 25° C. for 1 hour. The reaction liquid was diluted with dichloromethane, and washed with water. The solvent was distilled off from the reaction solution by concentrating under reduced pressure to obtain 4.1 g of a purple solid carboxylate (Compound 2) having tetrakis(pentafluorophenyl)boron(IV) anion (100% yield).

Abstract

A practical range of resistance to elution is not obtained in conventional colored compositions. Therefore, the present invention addresses the problem of providing a colored composition having betterelution resistance (less elution of dye) than do conventional colored compositions. The present invention pertains to a compound represented by general formula (1), and a colored composition including the compound. [In the formula, Dye represents a dye residue, R1 represents a hydrogen atom or a methyl group, Y0 represents a single bond, etc., Y1 and Y2 each independently represent -O-, etc., A1represents a specific alkylene group, etc., A2 represents an alkylene group optionally having -O- in the chain and having a group represented by general formula (2) in the chain or at an end, n represents 1 or 2 (in the formula, R1 and Y2 are the same as described above, R3 represents a group represented by general formula (2-1), etc., A3 represents a specific alkylene group, etc. [in the formula,R1, A3, and Y2 are the same as described above.].).]

Description

technical field [0001] The present invention relates to a polyfunctional polymer compound used for forming colored pixels such as a color filter, printing ink, inkjet ink, paint, and the like, and a coloring composition containing the compound. Background technique [0002] Known methods for forming color pixels in the manufacture of color filters such as liquid crystal display elements and solid-state imaging elements include a dyeing method or a dye dispersion method using a dye in a colorant, a pigment dispersion method using a pigment, and an electrodeposition method ( electrodeposition method), printing method, etc. In recent years, as characteristics of color filters, improvements in brightness and contrast are particularly required. According to the pigment dispersion method using pigments, heat resistance or light resistance is higher than that of dyes, so there is less deterioration in the heating process during panel production, and color pixels with high long-ter...
