Problems solved by technology

First, regarding magenta dyes, there is a problem that discoloration and hue changes due to ozone and light (sunlight, fluorescent lamps, etc.) are conspicuous compared with other dyes (cyan dyes, yellow dyes)
When these dyes are used alone, nozzles are less prone to clogging because of their high water solubility, but properties such as ozone resistance and light resistance are very low

Abstract

The purpose of the present invention is to provide a novel compound having a specific xanthene derivative multimeric structure, and that provides a printed item having greater ozone resistance, light resistance, and other image durability characteristics than conventional printed items. The compound is indicated by general formula (1). (In general formula (1), L indicates a divalent to tetravalent linking group. D indicates a residue having 1-5 hydrogen atoms removed from a compound indicated by general formula (2). m indicates an integer between 1 and 10. However the plurality of L can each be the same or different. n indicates an integer between 2 and 10. However, the plurality of D can each be the same or different. In general formula (2), R4-R24 each independently indicate a hydrogen atom or a substituent group, but same have at least one ionic hydrophilic group.)

Description

technical field [0001] The present invention relates to a novel compound having a multimer structure of a xanthene derivative, a coloring composition containing the compound, an ink for inkjet recording, an inkjet recording method, a color filter, and a color toner . Background technique [0002] As is well known, the inkjet recording method is a method of printing by ejecting ink droplets and attaching the droplets to a recording medium such as paper. This printing method can easily print high-resolution and high-quality images at high speed with an inexpensive device, and especially in color printing, it has been developed in recent years as a technology capable of replacing photographs as an image forming method. [0003] When forming a color image by an inkjet recording method, generally at least yellow ink, magenta ink, cyan ink and black ink are used. From the standpoints of odor and safety (eg, hazard at the time of fire extinguishing), water-based inks have convent...
