| 摘要 |
The invention relates to a polymerisable mixture (P) containing A) monomers or oligomers (A), each of said monomers or oligomers (A) comprising at least two polymerisable functional groups which are selected from (meth)acrylate ester groups, epoxy groups and vinyl ether groups, B) liquid-crystalline monomers or oligomers (B), each of said monomers or oligomers (B) comprising at least one mesogen group having an aromatic double ring structure and just one polymerisable functional group which is selected from (meth)acrylate ester groups, epoxy groups and vinyl ether groups, and C) between 1 and less than 50 wt. %, in relation to the polymerisable mixture, of a monomer (C) comprising at least one mesogen group having an aromatic double ring structure and no groups which can react with the polymerisable functional groups of the monomers or oligomers (A) and (B). |
