FIELD: organic chemistry. SUBSTANCE: organic dyes capable of forming lyotropic liquid crystalline phase are used as dyes for dichroic light polarizers. The present invention describes new dyes which are sulfonic acids of polycyclic dyes or mixtures thereof capable of forming lyotropic liquid crystalline phase. Dichroic light polarizers based on said dyes have improved polarization characteristics (Kd is more than 15). The present invention also describes 14 structures of new dyes. EFFECT: improved properties of the organic dyes. 1 tbl
