COATING COMPOSITION CAPABLE OF FORMING ALKALI-SOLUBLE LUBRICATING FILM SUITABLE FOR FORMING AND USE THEREOF

摘要

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 mu 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.
