Abstract
There is described an aqueous coating composition, the aqueous coating composition comprising an acrylic polyester resin, obtainable by grafting an acrylic polymer and a polyester material, the polyester material being obtainable by polymerizing: (i) a polyacid component, with (ii) a polyol component. At least one of the polyacid component and/or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. The coating composition further containing a crosslinking material, wherein the crosslinking material comprises material according to formula (I); as shown in claim; wherein Ris selected from aryl (such as Cto Caryl), or aralkyl (such as Cto Caralkyl); Rto Rare each independently hydrogen, alkyl (such as Cto Calkyl), aryl (such as Cto Caryl), aralkyl (such as Cto Caralkyl) or —CHROR; wherein Rand Rare each independently hydrogen, alkyl (such as Cto Calkyl), aryl (such as Cto Caryl), aralkyl (such as Cto Caralkyl), alkoxyalkyl (such as Cto Calkoxyalkyl) or an alkaryl (such as Cto Calkaryl); wherein at least one of Rto R, is —CHROR, suitably all of Rto R, are —CHROR.
