摘要

Novel colouring techniques by using biobased materials were studied. The orange or reddish orange colourant is obtained from (+)-catechin by an enzymatic reaction using tyrosinase. Human hair can be dyed orange or reddish orange by the colourant. The colourant does not cause reactions on skin such as erythema or oedema. The fastness to washing or light for hair dyed by it is high enough. The wool fabrics can be dyed by the treatment with (+)-catechin and the irradiation with ultraviolet light. The fastness to washing for the dyed wool is high enough. Woods are coloured with biobased materials by plasma radiation. The colours are very fast to rubbing.
