Disclosed is a novel amino-polyether-modified epoxy for an electrodeposition paint. The amino-polyether-modified epoxy compound is obtained by reacting amino polyether represented by a formula as follow, wherein m is an integer of 5 or more, R is hydrogen, methyl group or ethyl group, and n is 2 or 3, with polyglycidyl ether having a molecular weight of 1,000 to 7,000 and an epoxy equivalent of 500 to 3,500, wherein an equivalent ratio of a primary amino group of the amino polyether to an epoxy group of the polyglycidyl ether is controlled within the range of 0.52 to 1.0. |
