摘要 |
<p>UV light absorbing material (I) comprises a silica-matrix and covalently bound acrylamide (A) residues. UV light absorbing material of formula (I) comprises a silica-matrix and covalently bound acrylamide (A) residues. An independent claim is included for the preparation of (I) comprising preparing a nanodispersion sol by cohydrolysis of trialkoxysilane (IIa) of formula (Si(OR)3-R1>-N(R2>)-C(=O)-CR3>=CH-Ar1>-R4>) and gelling the obtained nanodispersion sol. R : 1-18C alkyl; R1>1-6C hydrocarbon; R2>H or 1-18C alkyl; R3>H or alkyl, halo, CN, acyl, carbalkoxy or carboxylic acid amide; Ar1>mono or polycyclic aromatic ring system (optionally containing hetero-cyclic rings, substituted by R4>), preferably phenyl (substituted by R4>); and R4>alkyl, alkoxy or OH.
