Abstract
Asymmetrical bis benzotriazoles of the formula I
where G2′ is perfluoroalkyl of 1 to 12 carbon atoms, preferably CF3, and where G2 does not contain said group are red-shifted and due to the asymmetry are particularly soluble and useful in a host of applications including automotive coatings, thermoplastics and especially in adhesive compositions, themselves useful in solar panels and other laminate structures.
