ABSTRACT:
An object of the present invention is to impart excellent gloss to an Urushi coating, improve drying properties, improve light fastness, and provide an environmentally responsible high-class lacquered article such as a ‘Byakudan’ (white sandalwood) coating or a ‘Tamamushi’ (iridescent) coating. This object has been accomplished by an Urushi lacquer comprising a naturally occurring raw Urushi or a refined Urushi, and metal colloid particles. As the metal colloid particles, precious metal colloid particles may preferably be used.
