Japanese Patent JP3352477
Kind Code:
B2
Abstract:
Disclosed is a cationic resin which can produce a pigment paste having high dispersion stability, an electrodeposition paint with good storage stability and a coated film with preferred corrosion resistance. The cationic pigment grinding resin for electrodeposition paint obtained by reacting a) a hydrophobic epoxy resin obtained by reaction of a bisphenol A type epoxy resin with a half-blocked isocyanate; with b) sulfide; which contains a group having specific chemical formula in one molecule, in which said bisphenol A type epoxy resin has an epoxy equivalent of 180 to 1,000, said hydrophobic epoxy resin has a solubility parameter of 10.0 to 11.0 and a conversion rate to tertiary sulfonium is 70 to 90%.
