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

Abstract: An Infra Red-reflective architectural paint composition comprising: i. red iron oxide pigment ii. phthalocyanine blue pigment iii. titanium dioxide and optionally yellow iron oxide wherein the composition is free of Infra Red-absorptive black pigments, Infra Red-transparent black pigments and Infra Red-reflective black pigments, has a lightness value, L*, when dry, of from 38 to 88 and the weight ratio of i:ii is from 3:1 to 15:1.
