LYOTROPIC LIQUID CRYSTALLINE COMPOSITION Russian patent published in 1995 - IPC

FIELD: in electronic optical devices. SUBSTANCE: a lyotropic liquid crystalline composition having a viscosity of less 8 carbon atoms than 10 Pa·s compress a surface active agent containing less than an amount of 5-55% of a solvent such as water and/or a water-immiscible solvent or completely or partially water-immiscible solvent, a solid having a free surface area energy of 18 to 240 mH/m and a particle size of less than 75 mcm in an amount of 0.5 to 50 wt and optionally surface active agents selected from the group consisting of lower ester, fatty alcohols and mixtures thereof, a water-soluble polymer with a α value of 0.6 to 1.115 which defines winding ability and permeability for media in an amount of 1 to 40 wt as well as a mixture of non-ionic polymers an amount of 0.5 to 30 wt The total amount of water, a water-immisible solvent, a water-missible solvent or a partially water-missible organic solvent and an additional surface active agent varies from 15 to 94.5 by weight of the lyotropic liquid-crystalline composition, and this amount together with the surface active agent containing at least 8 carbon atoms form a suspension or a solution. EFFECT: improved properties of the composition. 5 cl
