COATING COMPOSITION CONTAINING BENZOXAZINE COMPOUND

摘要

A novel method for improving the coating film smoothness and a cationic electrodeposition coating composition containing no heavy metal-based rust prevention agents such a lead compounds and capable of forming a coating film with a high corrosion resistance are provided. A coating composition forming a coating film under heating, which comprises, relative to a resin solid matter, 0.5 to 20% by weight of a compound having an N- substituted benzoxazine ring represented by the following general formula (1): in the formula, R is a hydrocarbon group having 1 to 8 carbon atoms.
