<p>PURPOSE:To provide the above compsn. free of clogging and excellent in ejectability, image sharpness, water resistance, light resistance and shelf stability, by using a specific water-soluble dye having a high molecular extinction coefficient and an excellent solubility in a wetting agent. CONSTITUTION:0.5-20wt.% water-soluble dye of the formula (wherein R1-2 is H, acyl, sulfonyl, or a substd. 1,3,5-triazine; and M is H, Li, K, Na, quaternary ammonium, or an org. amine) having a high molecular extinction coefficient and an excellent solubility in a wetting agent is blended with 5-80wt.% water- soluble org. solvent as a wetting agent such as diethylene glycol or polyethylene glycol, a preservative mildew-proofing agent (e.g., sodium dehydroacetate), a pH modifier (e.g., diethanolamine), a chelating reagent (e.g., sodium ethylenediaminetetraacetate), a rust-proofing agent (e.g., sodium thiosulfate), etc. according to need.</p> |
