摘要： Staining and discoloration of painted wood surfaces, as a result of bleeding into the top or finish coat of soluble coloring matter and tannins naturally present in the wood, is prevented by coating or impregnating the wood with a basic aluminum compound, particularly with a water soluble basic aluminum halide or derivative thereof. The basic aluminum compound may be applied in aqueous solution or non-pigmented emulsion for prefinishing building lumber, or applied in the form of a pigmented emulsion as a primer coat.The present invention relates to novel methods and compositions for application to the surfaces of woods, particularly to stain-susceptible woods, to prevent their staining or discoloring as a result of tannin and tocopherol or other waste-soluble coloring matter present in the raw wood, bleeding or migrating into a subsequently applied preservative or decorative paint film.
