Some experimental studies are presented on the compensated mixture cholesteryl chloride + cholesteryl laurate (65:35 wt yo) to which the pleochroic dye xylenazo-P-naphtol is added in two ratios: 1 : 100 and 1 : 200 by weight. The colour electro-optic effect, the dynamic scattering, and the pulsing electrohydrodynamic instabilities are studied. On the temperature-critical electric field diagram experimental conditions are indicated under which these effects may occur.cMecbm xonecTepnn KnopHAe + XonecTepm naypaTe (65:35 wt yo) K K O T O~O~~ 6bmo RccnenosaHbI usemo s n e~~p o o n~~s e c~~f i 3 @ @ e~~, AMHaMmecKoe paccemame H nynb-kl3JIomeHbI HeIEOTopbIe 3KCllepMMeHTaJlbHbIe HCCJle~OBaHHR HaA KoMIIeHCHpOBaHHbIfi IIpllAaBneHO KCEIJIeHa30-P-Ha@TOJIb B ABYX OTHOIIIeHHRX 1 :loo M 1 :200 IIO BeCy.
