Abstract
The present invention relates to a liquid-crystalline medium comprising one or more mesogenic compounds, one or more chiral compounds and one or more polymerizable mesogenic compounds wherein the medium exhibits a pitch of 0.55 [mu] m or more and a clearing point of 80 DEG C or more, and wherein, based on the total content of the medium, the content of the chiral compounds is greater than the total content of the medium, the content of the polymerizable mesogenic compounds is greater than the total content of the chiral compounds. The one or more polymerizable mesogenic compounds are present in an amount of at least 5% by weight or less. The invention further relates to a modulation material obtainable from the medium, and to a switching layer and a window element containing the material.
