PROBLEM TO BE SOLVED: To obtain a corrosionproof coating material composition for single- coating finishing capable of forming a coating film having excellent corrosionproofness and weatherability at normal temperatures and, simultaneously, by a single-coating step in order to maintain the corrosionproofness and the beauty of a structure made of steel. SOLUTION: This corrosionproof coating material composition for single- coating finishing comprises (A) an acrylic resin, (B) an epoxy resin having at least two epoxy groups, and (C) an amine curing agent and, at the same time, the above acrylic resin (A) contains (a) a cycloalkyl group-containing unsaturated monomer as a copolymer component, and as the compounding ratios of the acrylic resin (A) and the epoxy resin (B), the component (A) is 30-70 wt.% and the component (B) is 30-70 wt.%, each based on the total amount of the solid contents of these resins.
