Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an undercoating material composition which secures adhesion to the surface of a rust proof steel plate such as the surface of a zinc plated steel plate and its polishing workability, can form a coating film having excellent finishing after topcoating, and is particularly useful in the automotive repair field, and a repair coating method using the same. SOLUTION: The undercoating material composition comprises (A) an epoxy resin having a number average molecular weight of 5,000-30,000, (B) a pigment, (C) resin particles, and (D) a curing agent, and the content of the component (B) is 100-300 pts.wt. based on 100 pts.wt. resin solid content and, simultaneously, the component (C) is incorporated in an amount of 0.1-5 wt.%, in terms of the solid content, based on the weight of the component (B).
