Reaction products in which polyethers are grown from substituted phenol-containing Mannich bases have been found to be effective ashless dispersants and detergents for fuels and lubricants. The reaction products of the invention are obtained by (1) reacting phenol or a C1 to about a C40 alkylphenol with a suitable primary or secondary amine and a C1 to about a C30 aldehyde, thereafter (2) reacting the resultant intermediate product of (1) with an alkali metal or alkali metal salt thereof, and then (3) reacting the product of (2) with a C2 to about a C8 alkylene epoxide or mixtures thereof to produce a polyether-substituted Mannich base.
Disclosed herein is an ink-jet ink comprising in combination at least one compound selected from nitrogen compounds consisting of secondary amines and derivatives thereof, tertiary amines and derivative thereof, and complexes thereof and having at least one group selected from the group consisting of alkyl groups, a carboxyl group and the salts thereof, and a sulfonic group and the salts thereof, and a cyclic phosphate in a liquid medium in which a dye is dissolved or dispersed.
