Abstract

The present invention provides a benzotriazole derivative compound represented by a general formula, (wherein R3 represents an alkyl group, and R4 represents an acryloyloxyalkyl group or a methacryloyloxyalkyl group), as a novel compound capable of being suitably used as a highly light-resistant ultraviolet absorber or resin composition that exhibits an ultraviolet-blocking function over a prolonged period of time and that strongly absorbs wavelengths in the ultraviolet light range of 400 nm or less while ensuring little coloration.

Claims (4)

1. A benzotriazole derivative compound represented by the following general formula (1),

wherein in general formula (1), R 3 represents an alkyl group whose carbon number is 1 to 8, and R 4 represents an acryloyl oxyalkyl group whose alkyl carbon number is 1 to 2 or an methacryloyl oxyalkyl group whose alkyl carbon number is 1 to 2.

2. An ultraviolet light absorber containing the benzotriazole derivative compound according to claim 1 .

3. An ultraviolet light absorbing resin compound wherein the benzotriazole derivative compound according to claim 1 is compounded in a resin.
