Abstract
The present invention relates to a weather-resistant composition comprising a bisbenzotriazolylphenol compound represented by the general formula (1): [wherein A represents an alkylene group, and R1 and R2 represent a group (B): (in which R3 and R4 represent an alkyl group)], a meth)acrylate compound, and a curing agent; a coating material containing the weather-resistant composition as a main component; and a molded article. The composition can form a coating film which is not impaired in mechanical strength, exhibits excellent weather resistance, metal ion resistance and transparency for a prolonged period, and is less likely to cause surface cracks.
