<p>PURPOSE:To obtain the title ink causing no image restoration due to water, excellent in various printabilities, improved in desensitization effect, etc., by incorporating a specific active hydrogen-contg. polyamine with a reaction product formed by adding both ethylene oxide and butylene oxide to the active hydrogens in the amino group. CONSTITUTION:The objective ink can be obtained by incorporating (A) an active hydrogen-contg. polyamine of the formula H2N-R1-NH2 (R1 is branched 3-12C alkylene), formula I or II (R2-R4 are each 1-20C alkyl; n and m are each 1-12) with (B) a reaction product formed by adding <100wt.% (pref. 20-80wt.%) of ethylene oxide to the active hydrogens in the amino group followed by adding 4-70mol of butylene oxide to 1mol of the resulting adduct.</p> |
