  • This study investigated the effects of lacquer-finishing to prevent discoloration of coloring chestnut wood coated with natural dyes from deteriorating factors such as lights (indoor, 500 lux and outdoor, 50,000~70,000 lux), acid, alkali, and heat through measurement of color difference. Lacquer-finishing coating contributed to protection of intrinsic color of the natural dyeing woods in spite of severe treatment. In particular, dyeing liquor with alkali pH played a great role in prevention of light discoloration.
