A coating composition capable of forming an alkali-soluble lubricating film, which contains as main components an aqueous polyurethane composition (A) and a lubricating functionality-providing agent (B) at 1-30 wt % with respect to the solid content of the aqueous polyurethane composition, having excellent press moldability and scratch resistance, as well as lubricating surface treated metal articles with excellent press moldability and scratch resistance, that are coated with the coating composition to a dry film thickness of 0.5-5 &mgr;m. The coating composition preferably further contains as a main component silica particles (C) in an amount of 1-30 wt % with respect to the solid content of the aqueous polyurethane composition.

Coating composition capable of forming alkali-soluble lubricating film suitable for forming and use thereof

A soluble lubricating surface-treated stainless steel sheet with excellent shapability for fuel tanks, comprising a substrate having on both surfaces or one surface thereof a soluble lubricating resin film. Preferably, the soluble lubricating resin film mainly comprises (A) an alkali-soluble polyurethane resin composition containing a carboxyl group or a sulfonic acid group within the molecule and having a glass transition point of 100&deg; C. or more as a dry film and (B) a lubricating function-imparting agent in an amount of from 1 to 30% by mass based on the polyurethane composition.
