Use of metal chelate complex as a uv - safety means for polymer materials, inorganic, - organic hybrid polymers as well as in a process for the protection of uv - light-sensitive materials

摘要

Use of metal chelate complexes of the following formula (i) - as uv protection means in inorganic - organic hybrid polymer; Xm mln (i)whereinX is a c₁- to c₆-Alkoxy group, a c₆- to c₁₂-Aryloxy group or is halide and wherein, if m is greater than one, the individual x can be different from one another;m is an integer from 0 to 3;M for an ion of a metal selected from the group consisting of be, ca, ba, al, ga, ge, sn, pb, bi, ti, zr, co, cu, cd, ce and la is;L for a chelating ligand, which the metal ion m in a coordinated manner, wherein, if n is greater than one, the individual l can be different from one another;n is an integer from 1 to 3; and wherein(a) at least one group x as a ligand of the metal ion m and is hydrolyzed or at least one ligand l is hydrolyzable, so that the complex..
