A coating composition based on an acrylic resin which is useful for preparing lubricated steel products such as steel sheets or tubes is disclosed. The coating composition contains as additives a rust preventive which is a mixture of a sulfonamidecarboxylic acid and a cyclic amine and a water repellent. It exhibits improved rust-preventing properties when lubricated steel products having a coating film formed from the coating composition are stored for a prolonged period under coiled or stacked conditions.
