摘要： The present invention relates to a method for preparing a cationic microgel for electrodepositable coating and an electrodepositable coating composition comprising cationic microgel prepared by the same method. More specifically, the present invention relates to the method for preparing a cationic microgel for electrodepositable coating and the electrodepositable coating composition comprising cationic microgel prepared from by same method, wherein the method for preparing cationic microgel for electrodepositable coating comprises the steps of (1) preparing tertiary amine salt by reacting a tertiary amine having a hydroxy group with diisocyanate followed by neutralizing the resulting mixture with acid; and (2) dispersing the tertiary amine salt resin and polyepoxy resin polymer in a dispersion media, and then reacting the tertiary amine salt resin and polyepoxy resin polymer in the presence of diamine. The cationic microgel for electrodepositable coating exhibits excellent mechanical properties when applied to electrodepositable coating. The electrodepositable coating with the cationic microgel is excellent for edge coating and provides a good smooth coating film by inhibiting the formation of craters by adequately controlling the flowability during the hardening of the coating film.
