PURPOSE:To obtain the titled composition exhibiting excellent corrosionproof performance even at a thin coating film thickness and useful for the corrosionproof of steel structure, etc., by using mica flake as pigment and compounding to a tar epoxy resin paint. CONSTITUTION:The objective composition can be produced by compounding (A) a tar epoxy resin paint containing an epoxy resin (e.g. epoxypolyol resin having an OH equivalent of 80-300), a hardener and bitumen as film-forming components with (B) preferably 5-30vol.% mica flake (preferably having a flake diameter of 20-200mum and a thickness of 0.1-10mum) as a pigment.
