摘要： PROBLEM TO BE SOLVED: To obtain a coloring composition having good dispersibility and good gloss by incorporating a binder containing a rosin resin having amide groups and/or imide groups, a wax, and a colorant. SOLUTION: There are provided a coloring composition comprising 2-40 wt.% binder containing a rosin resin having amide groups and/or imide groups, 50-80 wt.% wax such as paraffin wax, microcrystalline wax or polyethylene wax, and 5-25 wt.% colorant and a hot melt composition containing the same. The rosin resin is obtained by treating a rosin, a carboxylic-acid-modified rosin, or the like with an amidating agent and/or an imidizing agent such as ammonia or a prim. or sec. amino-containing compound. The colorant used is a black pigment such as carbon black or graphite, an acetoacetic acid aryl amide-type monoazo yellow pigment, or the like.

摘要： PROBLEM TO BE SOLVED: To obtain the subject composition excellent in a printing quality, good in a record-retaining performance, excellent in metal corrosion prevention and useful for an ink jet printing method by including an azine-based coloring agent and a phosphorous compound for preventing metal corrosion. SOLUTION: This ink composition for an ink jet printing method comprising heating an ink solid at room temperature and subsequently jetting the melted ink on a recording medium to form recording dots contains (A) an azine-based coloring agent (preferably a nigrosine dye) and (B) a metal corrosion-preventing phosphorous compound (e.g. triisodecyl phosphite). The component A preferably contains in an amount of 0.5-5 wt.%, and the component B preferably contains in an amount of >=3 wt.%, especially 0.05-1 wt.%. Carnauba wax is preferably added to the vehicle of the objective composition. A vegetable wax, a higher fatty acid or the like is preferably further added in addition to the carnauba wax. The melt viscosity of the ink on printing is preferably controlled to 5-15 mPa.s, and the viscosity of the ink at room temperature is also preferably controlled to 10,000 mPa.s.

摘要： PROBLEM TO BE SOLVED: To obtain an ink composition having such excellent flow stability and low viscosity as to permit ink drops to be injected from fine nozzles by mixing a pigment with an alcohol-type wax having a hydroxyl value in a specified range to form a composition showing a melt viscosity in a specified range at the time of use. SOLUTION: An alcohol type wax having a hydroxyl value of 20-150 is used. The melt viscosity at the time of use is 5-30 mPa.s. The alcohol type wax is selected from among saturated linear alcohol-based alcohol type waxes and alcohol type waxes prepared by the oxidation of a starting material such as a paraffin wax, microcrystalline wax or petrolatum. The alcohol type wax is particularly desirably a 25-55C saturated linear alcohol and is desirably contained in an amount of at least 20 wt.% based on the composition.
