Abstract

PURPOSE: An ink jet recording ink with improved anticlogging properties, which is prepared by the addition of N-methyl-2-pyrrolidone together with glycerin, to a water-soluble direct dye.
CONSTITUTION: An ink, comprising 0.5W9wt% of a water-soluble direct dye, 7W 45wt% of glycerin and 1W6wt% of N-methyl-2-pyrrolidone. In view of the color tone, phyrical properties, etc. of the ink, part of said glycerin may be replaced by a polyhydric alcohol or its derivative, such as ethylene glycol, diethylene glycol, or mono-, di- or triethylene glycol alkyl ether. Less than 0.5wt% of said dye is ineffective for the development of necessary color tone and contrast, but more than 9wt% causes clogging in a spray nozzle. Less than 1wt% of N-methyl-2-pyrrolidone is ineffective, but more than 6wt% has an adverse influence on the physical property of the ink, etc.
