Abstract
Discoloration of water-based coatings due to uneven leaching of chromophoric substances, such as natural tannins and applied stains, is eliminated by contacting the surface with a water soluble anti-leachate compound selected from the group consisting of carboxylic acid salts, mono/polyfunctional amines and amine derivatives and their acid addition salts.
