Patent ID: 8557888

Claim:
Polymerizable composition, comprising: (a) 0.1 to 10 wt.-% initiator according to the following Formula I: R 1 —X—O—O—[Y—O—O—] n R 2 (Formula I) in which R 1 =is H, a linear, branched or cyclic aliphatic C 1 -C 20 radical, which can contain one or more multiple bonds and/or one or more heteroatoms selected from O, S and —NR 5 —, an aromatic C 6 -C 14 radical or a combination of one such aliphatic and one such aromatic radical or has one of the meanings given for R 2 ; R 5 =is H, phenyl or C 1 -C 9 alkyl; X=is —CO— or is absent; R 2 is —CO-M, —SO 2 -M or —P(═O)(-M)(—R 3 ); R 3 =is R′, —OR′, or —OO(CO) m R′, wherein R′ is H, a linear, branched or cyclic aliphatic C 1 -C 20 radical, which can contain one or more multiple bonds and/or one or more heteroatoms selected from O, S and N, an aromatic C 6 -C 14 radical or a combination of such an aliphatic and such an aromatic radical, and m is 0 or 1; M=is —CH═CH 2 or —C(R 4 )═CH 2 ; R 4 =is a C 1 -C 10 alkyl radical or a C 3 -C 8 cycloalkyl radical, wherein these radicals can contain one or more S or O atoms, a phenyl radical or benzyl radical, wherein the named radicals can be halogenated, —F, —Cl or —Br; Y=is a bivalent, linear, branched or cyclic aliphatic C 1 -C 8 radical; and n=is 0, 1, or 2, (b) 0.01 to 10 wt.-% photoinitiatior (c) 10 to 99 wt.-% polymerizable binder, (d) 0 to 85 wt.-% filler, and (e) 0 to 30 wt.-% stabilizers and/or additives, relative in each case to the overall mass of the composition.
