<p>A paint based on a saturated polyester comprises 5-50 % of an amino-resin such as an alkylated melamine resin, and 1-20 % of an aluminium organic compound, percentages being by weight on the weight of the polyester, preferably in a volatile liquid medium. The aluminium organic compound may comprise alkoxy or ethylacetoacetate groups. When used to coat metal e.g. aluminium sheet, the paints have improved long-term weathering properties.</p> |
