Hydrophilic coloring agent for recording image, aqueous coloring composition for recording image, method and system for recording image

Image-recording, hydrophilic colorants represented by the below-described formula (1) are disclosed. These colorants can be provided as colorants capable of forming images excellent in print quality such as chroma, gloss, density, light fastness and abrasion fastness, and also as hydrophilic colorants capable of affording inks excellent in physical properties such as long-term storability and press stability. [ organic pigment ] ˆ’ [ linking group ] €ƒ€ƒ€ƒ ˆ’ [ hydrophilic compound ] wherein the [organic pigment] is a hydrophobic pigment having no hydrophilic group by itself, the [linking group] is a group linking the [organic pigment] and the [hydrophilic compound] with each other and blocking an effect of the [hydrophilic compound] on the [organic pigment], and the [hydrophilic compound] is an anionic, cationic and/or nonionic, hydrophilic compound.
