Abstract
There is provided a desensitizer used in a quick-drying desensitizing ink for no-carbon copy paper, which is a compound represented by the formula ##STR1## wherein R.sup.1 represents hydrogen atom or methyl group; R.sup.2 represents hydrogen atom, a methyl group, a phenyl group which may have as substituent an alkyl group having 1 to 12 carbon atoms, CH.sub.2 .dbd.CHCO--, ##STR2## R.sup.3 represents CH.sub.2 .dbd.CHCO--, ##STR3## and l and m are integers of 1 or greater than 1, l+m being not greater than 46, and p is zero or an integer of 1, provided that when p is 1 zero R.sup.2 is the groups other than ##STR4##
Claims7
No-carbon paper containing a pigment and a desensitizer which is a compound represented by the formula ##STR53## wherein R.sup.1 represents a hydrogen atom or methyl group;
