<p>PURPOSE:To provide a pigment compsn. which has high gloss, gravure printability and excellent stability with time and transparency, by blending a higher fatty acid-modified silicone oil with a pigment in a specified ratio. CONSTITUTION:0.01-1wt% higher fatty acid-modified silicone oil is blended with a pigment. Examples of pigments are org. pigments such as azo pigment, condensed azo pigment and phthalocyanine pigment and inorg. pigments such as carbon black, titanium oxide, chrome yellow and zinc oxide. Examples of the higher fatty acid-modified silicone oils are silicon oil modified with higher fatty acids such as palmitic or stearic acid. When the amount of the oil is less than 0.01wt%, little effect can be obtd., while the amount exceeds 1wt%, there are disadvantages that the tinting power and degree of color development are reduced and the fitness as the ink is lost.</p> |
