COATING COMPOSITION AND LUBRICATED METAL SHEETS

摘要

The present invention provides a coating composition comprising a methacrylic resin prepared by copolymerization of styrene or a substituted styrene (A), a methacrylic ester obtained from an alcohol having at least two carbon atoms and methacrylic acid (B), and an olefinic compound having at least one carboxylic group (C), in which the molar ratio thereof is 1 : (0.05 to 44.5) : (0.12 to 13), and also provides a lubricated metal sheet to which the coating composition is applied. The lubricated metal sheet has superior characteristics of dissolution of the film in an alkaline solution, chemical processing, paint dryness, blocking resistance, corrosion resistance, stability of coating composition, and press formability (powdering resistance and galling resistance).
