Abstract
An aqueous polymer coating composition comprising at least: a vinyl polymer A having a wt average molecular wt Mw within the range of from 1,000 to 150,000 g/mol and an acid value >5 mgKOH/g; and a vinyl polymer B having a molecular wt Mw of at least 80,000 g/mol and an acid value <35 mgKOH/g; wherein I) the wt % of olefinically unsaturated monomers used to form polymer A and polymer B are in the ratio of 5:70 to 95:30 and add up to 100%; II) at least 20 wt % of at least one of polymer A and or polymer B is derived from at least one bio-renewable olefinically unsaturated monomer.
