<p>A coating composition which may be water based and which is adapted for metallic substrates is disclosed, having: (1) binder resin comprising acrylic polymer having carboxy functionality, and (2) a curing agent comprising hydroxyalkylamide, wherein the ratio of hydroxy groups in the hydroxyalkylamide to carboxy groups in the binder resin is less than 0.5:1, preferably less than 0.4 to 1, and most preferably less than 0.35:1. The composition has been found to yield films exhibiting good resistance to water at high temperatures, thereby rendering them particularly suitable for use on metal food and beverage containers that are subjected to sterilization or pasteurization processes.</p> |
