| 摘要 |
A process for coloring wood whereby the resulting color will not change or substantially fade upon exposure to long term environmental weathering, which process comprises contacting the wood with an aqueous solution containing 0.01%-10% of an iron salt derived from a mono-, di-, or tri-carboxylic acid or a mono-, di-, or tri-carboxylic hydroxy acid containing 1-6 carbon atoms. The iron salt solution of this invention may be used to color nontreated wood as well as wood treated with known preservative compositions containing one or more heavy metals including copper, chromium, arsenic and zinc.
