<p>p-(3-18C Alkyl)-acetophenone derivatives with hydroxy, alkoxy or acyloxy groups on the alpha-carbon atom are used as photoinitiators in radiation-curable, anti-adhesive coating materials based on radiation-curable organopolysiloxanes with (meth)acrylate ester groups. The use of radiation-curable coating materials (I) containing (A) radiation-curable organopolysiloxane(s) with (meth)acrylate ester groups and (B) a photoinitiator of the following formula, for the production of anti-adhesive paints, protective layers and coatings. (Structure, page 9) R1 = 3-18C alkyl; R2 = H or 1-4C alkyl; R3, R4 = H or 1-6C alkyl, or both may be linked to form a 5- or 6-membered carbon ring; R5 = H, alkyl or alkanoyl .</p> |
