Abstract
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 <IMAGE> (I) wherein R1 represents hydrogen atom or methyl group; R2 represents hydrogen atom, a methyl group, a phenyl group which may have as substituent an alkyl group having 1 to 12 carbon atoms, CH2=CHCO-, <IMAGE> +TR <IMAGE> R3 represents CH2=CHCO-, <IMAGE> <IMAGE> <IMAGE> +TR <IMAGE> 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 R2 is the groups other than <IMAGE> +TR <IMAGE>
