Autoxidisable coating composition

An autoxidisable coating composition comprising:

• i) 10 to 60 wt % of an autoxidisable material having:
• a) a number average molecular weight <4500 g/mol;
• b) optionally 1 to 20 carbohydrate units;
• c) a fatty acid residue content of ≧60 wt %;
• and
• d) a viscosity at 100% solids in the range of from 0.05 to 5 Pa·s at 20+/−5° C. at a shear rate of 5000 s−1;
• and
• ii) 90 to 40 wt % of an autoxidisable urethanised resin which is a reaction product of at least an isocyanate, an alcohol, and an unsaturated oil or an unsaturated fatty acid, wherein the autoxidisable urethanised resin has:
• e) a number average molecular weight ≧4000 g/mol;
• f) a fatty acid residue content of ≧50 wt %;
• g) an acid value in the range of from 0 to 20 mgKOH/g resin;
• h) an isocyanate content in the range of from 1 to 35 wt % by weight of autoxidisable urethanised resin;
• and
• wherein i)+ii)=100 wt % based on total solids content of the autoxidisable coating composition.
