each R7 is independently vinyl or 2-propenyl; and
R12, R14, R21 and R23 are independently phenoxy which is substituted by a branched C3-C24-alkyl radical;
or the C2-C3-alkenyl-substituted compound (I) is a compound having the formula (I-B.1)

OG Complex Work Unit Chemistry
wherein
n is 2;
one of R5 and R6 is hydrogen and the other is unsubstituted phenyl, and
each R8 is phenyl substituted with one or two C2-C3-alkenyl groups;
or
one of R5 and R6 is hydrogen and the other is phenyl substituted with one or two C2-C3-alkenyl groups, and
each R8 is unsubstituted phenyl;
where the curable silicone resin mixture comprises a curable organopolysiloxane and a hydrosilylation catalyst, where the curable organopolysiloxane contains silicon bonded hydrogen atoms which can undergo a hydrosilylation reaction in the presence of the hydrosilylation catalyst.
