Abstract

A wood preservative composition comprises a solution of a wood preserving agent in an organic solvent, includes a dye which is inherently insoluble in the organic solvent but is rendered soluble in the said solvent such that the dye is present in the composition during impregnation of wood therewith whereupon the dye becomes insoluble in the solvent. The dye does not bleed into most types of wood paint when such a paint is subsequently applied to the impregnated wood. The dye may be rendered soluble in the organic solvent either by including in the composition a solvent for the dye, which solvent is miscible with the main solvent, or by chemically modifying the dye to a form which is soluble in the organic solvent but which reverts to the insoluble form when wood is impregnated with the composition. A method of colouring wood using the composition is also provided.
