Abstract
Abstract The present invention relates to an ink for ink-jetting containing at least a coloring material, water soluble organic solvent and water, comprising: 0.01-5.0% by weight of alkylene oxide adduct of acetylene glycol, represented by the formula (A): ##STR1## (in which R 1 -R 4 , are respectively an lower alkyl group; l is an integer of 2 or 3; and m and n are respectively an integer of 1 or more); 6.0-14.0% by weight of a compound selected from the group consisting of a polyalcohol having three hydroxy groups, alkylene glycols represented by the formula (B): HO(C.sub.x H.sub.2x O).sub.y H (B) (in which x and y is respectively an integer, provided that x is 2 or more and x and y have a relation of 2≦X×y≦6), and a mixture thereof; 4.0-10.0% by weight of a lower alkyl ether of alkylene glycol represented by the formula (C): HO(C.sub.p H.sub.2p O).sub.q R (C) (in which R is a lower alkyl group, p and q is respectively an integer, provided that p is 2 or more and p and q have a relation of 2≦p×q≦6), or a mixture thereof, 2.0-8.0% by weight of polyalkylene glycol having a molecular weight of 150-600; and water, % by weight being based on total weight of the ink.
