Colloidal metal-containing Urushi lacquer and Urushi lacquered article

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.
