Autoxidisable aqueous coating compositions

摘要

An autoxidisable aqueous varnish composition comprising
a) film forming polymer latex binder system comprising, on a non-vol basis
i) 40-60wt% soft autoxidisable polymer particles of Fox Tg less than 5°C
ii) 60-40wt% hard polymer particles of Fox Tg at least 40°C
wherein the soft autoxidisable polymer particles comprise at least 60wt% gel
b) a carrier liquid comprising at least 50wt% water and an amount of a volatile organic material of from 0 to 2wt% when calculated on the total liquid varnish composition
c) optionally pigment at a pigment to binder weight ratio up to 0.05:1 calculated on a non-vol basis.
