Title: COMPOUND HAVING XANTHENE SKELETON, COLORANT COMPOSITION, INK FOR INKJET RECORDING, INKJET RECORDING METHOD, INKJET PRINTER CARTRIDGE, AND INKJET RECORDING MATERIAL
Abstract:
The purpose of the present invention is to provide: a compound which has excellent printing density and which makes it possible to form an image with excellent image fastness such as lightfastness, ozone resistance and moisture resistance; a colorant composition; an inkjet recording ink that contains the aforementioned compound and the aforementioned colorant composition; an inkjet recording method using the aforementioned inkjet recording ink; an inkjet printer cartridge; and an inkjet recording material. The compound is represented by general formula (1). In general formula (1), R1 and R2 are independently a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, and R3, R4 and R5 are independently a substituent. M represents a hydrogen atom or a counter cation. The M's may be the same or different. n3, n4 and n5 independently represent numbers between 0 and 4. If n3, n4 and n5 each represents a number greater than or equal to 2, then multiple R3's, R4's and R5's may be the same or different.
