Zusammenfassung:	PURPOSE:To provide a water-soluble rust-preventive paint composed of PVA and a small amount of alpha-nitroso-beta-naphthol, having excellent oil-resistance, heat-resistance and hot-oil resistance and applicable to an oil-immersed electrical apparatus, etc. CONSTITUTION:The objective paint can be produced by compounding (A) 100 pts.(wt.) of PVA with (B) 1-10pts. of alpha-nitroso-beta-naphthol and (C) preferably 300-800pts. of ion-exchanged water. The paint may be further compounded with (D) preferably 25-35pts. of carbon black or titanium dioxide fine powder, (E) preferably 1-3pts. of ultrafine silica anhydride particles (e.g. having particle diameter of about 0.012mu) and (F) preferably 10-20pts. of a hardly water-soluble metal oxide (e.g. silica gel) or inorganic salt (e.g. calcium carbonate).
