摘要： A protective agent for hair dyes to prevent fading of the dye because of the action of sunlight or other factors. This agent is a reaction product of either acrylonitrile or a mixture of acrylonitrile-benzophenone and an oxy-substituted benzophenone with phenacetin. The proportion of the two reactants may vary from about 3:1 to about 200:1 parts by weight of the acrylonitrile or acrylonitrile-benzophenone mixture relative to the phenacetin.
