Abstract:
1. A transparent silicone mixture crosslinkable under the influence of light, comprising (A) at least one organosiloxane resin comprising units of the formulae I, II, III and IV in which R are saturated hydrocarbyl radicals optionally substituted by halogens, and having 1-40 carbon atoms, —OH, or a C with the proviso that at least 20 mol % of the units are selected from units of the general formulae III and IV, at least 2 of the R radicals are alkenyl radicals having 1-10 carbon atoms and at most 2% by weight of the R radicals are —OH radicals, (B) at least one polyorganosiloxane containing at least two alkenyl groups per molecule and having a chain length of the longest chain of 200 to 10,000 siloxy units, in an amount of from 10 to 90 parts by weight per 100 parts of organosiloxane resin (A), (C) at least one organosilicon compound containing at least two SiH functions per molecule and (D) as one catalyst, MeCp(PtMe
