Light Resistance of Natural Dye-colored Veneer and Clear Coated Cylindrical Laminated Veneer Lumber

In order to develop the end use of cylindrical laminated veneer lumber (LVL) such as wooden crafts, the light resistance properties of natural dye-colored and finished cylindrical LVL was investigated. The study results were as follows; The cross section of LVL showed the high-er light resistance than its tangential section, and the light resistance also increased with surface coated. On the other hand, LVL specimen were colored by 9 natural dyes of amur cork-tree etc., and the natural and apparent hue harmonized with wood was found after coating and light resistance test. Particularly, The dyes extracted from amur cork-tree, persimon and sappan wood showed orange color, reddish brown and red color respectively, giving an accenting effect to original wood color.
