Abstract

A coil coating composition consisting essentially of (A) a binder component comprising a mixture of a linear polyester resin and a branched polyester resin, having a hydroxyl value of 40 to 90, and (B) a crosslinking component selected from melamine resin, at least part of which is methyl methylolated melamine, or isocyanate compound. Said polyester resins are herein defined. The coating composition is useful in a coil coating and results in a coating with excellent properties in respect of hardness, bending processability, fastness to boiling water, weather resistance, chemical resistance, marker stain resistance and the like.
