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.

Abstract: PROBLEM TO BE SOLVED: To obtain a toner having an improved pulverizing behavior by incorporating at least one of a part having a specified steel ball indentation hardness and a perfectly tactic polyalkylene wax. SOLUTION: This toner contains 10-95wt.% at least one kind of resin binder, 0.01-40wt.% at least one of a part having a number average mol.wt. of 2,000-12,000 and at least 800 bar steel ball indent hardness and perfectly tactic polyalkylene wax and 0.1-10wt.% colorant or further contains other components if necessary. The resin binder is styrene-alkyl methacrylate resin or styreneacrylic acid resin, e.g. styrene-butyl methacrylate resin contg. 50-90wt.%, preferably 70-85wt.% styrene and 10-50wt.%, preferably 15-30wt.% butyl methacrylate. The polyalkylene wax is polypropylene wax.

Abstract: The novel carriers consist of steel cores which have an iron oxide- containing coating of the formula (FeO)x . Fe2O3 where x = 0.1 - 1. The carriers are stable and effective over long cycle times (6 .10 prints). … The carriers are obtained by treating steel cores (steel spheres) with defined small amounts of sulphuric acid of defined concentration, partial oxidation of the treated cores and drying at 60-150 DEG C at
