Abstract
Suspension agent for synthetic resin powders comprising an aqueous emulsion wherein there is contained, in a concentration of about 1-7.5 percent by weight: (A) a mixture of about 95-40 molar percent of an aminoamide of the general formula ##STR1## wherein R represents a saturated or unsaturated hydrocarbon group having 13-19 carbon atoms, n represents an integer of between 2 and 6, and R.sub.1 and R.sub.2 represent alkyl groups having 1-3 carbon atoms; and (B) about 5-60 molar percent of a fatty acid or mineral acid salt of this aminoamide.
