Abstract
It is known that a black urushi film exposed to light loses its gloss. Homogenization process were applied to black urushi lacquer for improving light-resistance of urushi film. However the dryability became worse by this methods. Then in order to improve the dryability for black urushi lacquer enzyme, i.e. laccase, was added into lacquer. As a result, the drying speed and light-resistance were improved with a combination of homogenization and laccase addition. Consequently black lacquer for practical use was obtained.
