Abstract
Provided is an ink comprising a compound having at least one carbonyl group and a hydrazide compound selected from the group consisting of a styrene-maleic acid resin having at least two hydrazide groups, a polyacrylic acid having at least two hydrazide groups and a compound represented by the formula ##STR1## wherein R represents (CH.sub.2).sub.n or C.sub.6 H.sub.4, where n is an integer of 0 to 10, or the formula ##STR2##
Claims14
