  • Patent number: 10919868
    Abstract: Provided are benzotriazole derivative compounds of the general formula that are novel compounds capable of strongly absorbing light in the ultraviolet range, particularly 300-330 nm, while strongly absorbing light in the visible light short-wavelength range up to around 450 nm and being used suitably as a light absorber having high light fastness with a light-blocking function over an extended period of time. Preferably, R1 is a hydrogen atom or alkyl group, R2 is a C1-8 alkyl group, R3 is a hydrogen atom, alkyl group, acryloyloxyalkyl group, or methacryloyloxyalkyl group.
