多くの特性が損なわれ、特定の用途のみしか使用できず
汎用性が失われる結果となっている。In order to improve this washing fastness, measures such as changing the resin leakage in the composition or changing the dye type have been taken, but while washing fastness is improved, many other characteristics This results in a loss of versatility as it can only be used for specific purposes.
本発明は斯る問題点を解決し、インキのもつ他の特性を
損うことなく洗濯堅牢性を向上できる油性インキの提供
を目的とする。The present invention aims to solve these problems and provide an oil-based ink that can improve washing fastness without impairing other properties of the ink.

特徴とする油性インキを提供するものである。(Another Means to Solve the Problems) In order to achieve the above object, the present invention provides an oil-based ink containing a basic dye or a dye obtained by making a basic dye oil-solubilized in an oil-based ink containing 0.1 to 10% by weight of tannin. The present invention provides an oil-based ink characterized by containing an acid.

るものである。(Function) Basic dyes are generally suitable for dyeing animal fibers, but
It is not suitable for dyeing vegetable fibers and is rarely used alone, but rather in combination with a dyeing aid such as tannic acid. This method utilizes the phenomenon that when tannic acid binds to a basic dye, a lake dye is produced and stabilized inside or on the surface of the fiber. The present invention is an application of the principle of basic knowledge, and even when an organic solvent in which tannic acid is soluble and a basic dye or an oil-soluble dye of a basic dye are mixed, the effect of tannic acid is large and the washing fastness is improved. This will lead to improved results.
