Patent ID: 7767727

Claim:
An autoxidisable architectural coating composition suitable for application to surfaces at ambient temperatures and in natural daylight which composition contains an autoxidisable binder polymer and a promoter system for promoting autoxidation of the autoxidisable binder polymer wherein the system comprises a) less than 0.01 wt % of cobalt ions based on the weight of the autoxidisable binder polymer in the coating composition, b) from 0.001 to 0.06 wt % (based on the weight of autoxidisable binder polymer in the coating composition) of metal ions other than cobalt ions being metal ions which promote surface autoxidation, c) 2,2-dimethoxy-1,2-diphenylethan-1-one and wherein the binder polymer is free of moieties derived from isocyanate functional ethylenically unsaturated compounds.
