in ethyl acetate, methyl ethyl ketone and toluene, insoluble in
water. UV absorbers is currently the most widely used light
stabilizers, this is a class capable of strong, selectively absorb
high-energy ultraviolet light, and energy conversion, in the form
of heat or radiation to harmless low energy consumption or energy
release substances. Containing a hydroxy group ortho of
benzophenone ultraviolet absorbing only below 380nm, almost no
absorption of visible light.
