Zusammenfassung:A film-forming binder polymer for a coating composition such as a paint, varnish or woodstain where the polymer is modified by the presence of bonded moieties derived from plant gum, particularly plant fibre gum obtainable fro m plant fibre, especially corn fibre gum and more particularly moieties derive d from proteo-xylans and/or furanose. The modified binder polymer minimises th e need to use coalescing solvents without producing poor dried paint coatings which fail the scrub resistance tests also improves the opacity of the dried coating composition.
