BENZOTRIAZOLE DERIVATIVE COMPOUND AND THE USE THEREOF

Abstract

The present invention provides a benzotriazole derivative compound represented by a general formula,

##STR00001##

(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

1. A benzotriazole derivative compound represented by the following general formula (1). ##STR00016## in the wherein in general formula (1), R.sub.3 represents an alkyl group whose carbon number is 1 to 8, and R.sub.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.
