Abstract

Photocrosslinkable, mesogenic mixtures, especially for optical or electro-optical devices, exhibit improved properties when, in addition to containing two or more liquid-crystalline monomers each having at least two terminal polymerizable groups, they contain at least one non-liquid-crystalline monomer having no or, at most, one alicyclic or aromatic structural unit and having at least one terminal polymerizable group.
