Zusammenfassung:	PURPOSE:To provide a lubricating resin treated org. coated steel panel excellent in press a moldability, spot weldability and conductivity. CONSTITUTION:Chromate films are provided to both surfaces of a zinc or zinc alloy plated steel panel so that the adhesion amt. of chromium is 10-200mg/m per a single surface in terms of chromium and thermosetting compsn. layers each containing a polyol resin, a curing agent, polyethylene wax and silica as essential components are further formed on the upper surfaces of the chromate films to obtain an org. coated steel panel. The resin in the thermosetting composition is constituted by blending a polyol resin with glass transition temp. (Tg) of -30% to 30 deg.C and a polyol resin with Tg of 30-90 deg.C in a wt. ratio of 10/90-90/10 and the adhesion amt. of the thermosetting compsn. is 0.1-0.5g/m on a dry wt. basis per the single surface of the steel plate.
