    摘要: In formula (I), each R1, R2 and R3 is independently —OR4, R4 being independently hydrogen or a C1 to C24 hydrocarbyl group optionally containing heteroatoms, or C1 to C24 hydrocarbyl groups optionally containing heteroatoms; n is 2, 3, 4 or 5; o is 2, 3, 4 or 5; p is 2, 3, 4 or 5; with the proviso that at least one of R1 and at least one of R2 and at least one of R3 is —OR4. A coating is obtained by applying the coating composition to a substrate for protecting the substrate against UV/Vis-radiation or for stabilizing the substrate against the deleterious influence of UV/Vis-radiation.
