1. An aqueous coating composition comprising:
a) a graft acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material, the polyester material being obtainable by polymerizing:
i) a polyacid component, with
ii) a polyol component,
wherein at least one of the polyacid component and/or the polyol component comprises a monomer having an aliphatic group containing at least 15 carbon atoms;
wherein the polyester material has a gross hydroxyl value of 7 to 40 mg KOH/g;
wherein the aliphatic group-containing monomer is a dimer fatty acid; wherein 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 is grafted with the polyester material via the use of said functionality,
b) a crosslinking material.
 
20. A powder coating composition, the powder coating composition comprising:
a) a graft acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material, the polyester material being obtainable by polymerizing:
i) a polyacid component, with
ii) a polyol component,
wherein at least one of the polyacid component and/or the polyol component comprises a monomer having an aliphatic group containing at least 15 carbon atoms;
wherein the aliphatic group-containing monomer is a dimer fatty acid;
wherein 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 is grafted with the polyester material via the use of said functionality,
wherein the polyester material has a gross hydroxyl value of 5 to 50 mg KOH/g;
b) a crosslinking material.
