Abstract

PURPOSE: To provide the titled ink which has good solubility, shade and brightness and in which water resistance and light resistance are improved, containing water, a polyhydric alcohol or polyhydric alcohol ester and a water-soluble dye prepd. by incorporating a direct dye into an acid dye.
CONSTITUTION: In an ink contg. a basic component consisting of a water-soluble dye, a polyhydric alcohol or a polyhydric alcohol ester and water, a dye prepd. by incorporating at least 20% direct dye having a solubility of at least 2% into an acid dye is used as the water-soluble dye. For example, in a red ink, a yellow or an orange direct dye is blended with a Magenta or violet acid dye. When the ink contg. the above mixt. of the direct dye and the acid dye is injected through a nozzle and printed on a recording sheet, a dye state is formed in which each dye is alternately arranged on the recording sheet microscopically. Thus, the dyeing power of the acid dye is promoted by the relatively strong dyeing power of the direct dye.
