Abstract: PROBLEM TO BE SOLVED: To obtain a liquid water-based dye preparation excellent in water resistance and light resistance and desirable for the production of writing inks or printing colorants by mixing a dye with carbon black and polyethylene glycol. SOLUTION: This preparation comprises 0.1-15wt.%, based on the weight of the preparation, dye comprising 90-100wt.% dye represented by the formula (Kat is a metallic ion or an ammonium ion), 1-40wt.% carbon black having a particle size of 13-100nm, 0.1-15wt.% polyethylene glycol having an average molecular weight of 300-9,000 and the balance of water. This preparation is diluted with water or a mixture comprising water and a water-miscible organic solvent to obtain an ink. It is diluted with a 1-4C alkanol optionally together with water, and the diluted preparation is optionally mixed with a binder to obtain a colorant for a water-based alcoholic coating material or for printing.
