(a) a reactive silicone compound obtained by polycondensing a diaryl silicic acid compound of Formula [1] below with a silane compound, selected under compounds of Formula [2] and Formula [2b] below in the presence of an acid or a base;wherein Ar1 and Ar2 are independently a phenyl group optionally substituted with a C1-C6 alkyl group, and X is a group which can undergo a hydrolytic condensation reaction, and wherein Ar3 is naphthyl or anthracyl substituted with at least one group having a polymerizable double bond, or wherein Ar3 is phenyl substituted with at least one group having a polymerizable double bond other than vinyl, or is phenyl substituted with at least two groups having a polymerizable double bond, and
(b) a compound having at least one polymerizable alkenyl group of Formula [3],wherein R1 is a hydrogen atom or methyl group, L is a hydrogen atom, a C1-20 aliphatic hydrocarbon residue having m-valence that is optionally substituted with a phenyl group, a C1-20 aliphatic hydrocarbon residue having m-valence that optionally contains an ether bond, or a C1-20 polyvalent alcohol residue optionally containing an ether bond, Ar4 is a monocyclic or bicyclic or tricyclic, in each case aromatic hydrocarbon residue with n+1 valences, m is 1 and n is 2; or
wherein R1 is a hydrogen atom or methyl group, L is a single bond, an oxygen atom, a C1-20 aliphatic hydrocarbon residue having m-valence that is optionally substituted with a phenyl group, a C1-20 aliphatic hydrocarbon residue having m-valence that optionally contains an ether bond, or a C1-20 polyvalent alcohol residue optionally containing an ether bond, Ar4 is a monocyclic or bicyclic or tricyclic, in each case aromatic hydrocarbon residue with n+1 valences, m is 2 or 3 and each of n is independently 1 or 2; with the proviso that when L is a single bond or an oxygen atom, m is 2. |
