Abstract: The description is concerned with a liquid crystal composition of the guest-host type which contains a pleochroic dye dissolved therein. The dye molecule has an end group or end groups in the molecule represented by the general formula: ##STR1## where Ro designates a straight chain of alkyl group, in which methylene group not adjacent to the nitrogen atom may be substituted by oxygen atom or sulfer atom; R1 designates an alkyl group having a chain length different from that of the alkyl group of Ro or a group ##STR2## in R1 a methylene group not adjacent to the nitrogen atom may be substituted by oxygen atom or sulfur atom, and R2 designates hydrogen atom, alkyl group, alkoxy group, cycloalkyl group or dialkylamino group.

Abstract: WATER-SOLUBLE AZO-PYRIMIDINE DYESTUFFS OBTAINED BY COUPLING DIAZO OR TETRAZO COMPOUNDS DERIVED FROM AROMATIC MONOAMINES OR DIAMINES IN AN EQUIVALENT RATIO OF ABOUT 1:1 WITH AN OPTIONALLY SUBSTITUTED 2.4.6-TRIAMINOPYRIMIDINE COMPOUND WHICH CAN BE COUPLED IN THE 5-POSITION, OR IN AN EQUIVALENT RATIO OF 1:2 WITH IDENTICAL OR DIFFERENT 2,4,6-TRIAMINO-PYRIMIDINE COMPOUNDS OF THIS TYPE, OR WITH ONE EQUIVALENT OF SUCH A TRIAMINO-PYRIMIDINE COMPOUND AND ONE EQUIVALENT OF ANOTHER COUPLING COMPONENT AND, IN THE CASE OF COUPLING COMPONENTS CONTAINING DIAZOTIZABLE AMINO BROUPS, THE DISAZO DYESTUFFS RESULTING FROM COUPLING SUCH DIAZOTIZED AMINOAZO-PYRIMIDINE DYESTUFFS WITH ANOTHER COUPLING COMPONENT, OR DYESTUFFS OBTAINED BY COUPLING TWO EQUIVALENTS OF THE AFORESAID DIAZOTIZED MONOAMINES WITH A COUPLING COMPONENT COMPRISING TWO PYRIMIDYL NUCLEI LINKED TOGETHER VIA A HYDRAZINO BRIDGE OR VIA CERTAIN ORGANIC BRIDGE MEMBERS, THE COMPONENTS BEING SO CHOSEN THAT THE FINAL DYESTUFF CONTAINS AT LEAST ONE SALT-FORMING, WATER SOLUBILIZING GROUP WHICH DIS SOCIATES ACID IN WATER AND AT LEAST THREE RINGS PER MOLECULE, WHICH ARE NOT FUSED WITH ONE ANOTHER, AND OF WHICH PREFERABLY AT LEAST TWO ARE CARBOCYCLIC OR HETEROCYCLIC AND OF AROMATIC CHARACTER AND THE THIRD CAN BE AROMATIC, OR A PARTLY UNSATURATED OR A SATURATED ALICYCLIC RING. SAID DYE STUFFS PRODUCE POLYAMIDE DYEINGS HAVING GOOD FASTNESS TO LIGHT AND ABRASION AND EXCELLLENT WET-FASTNESS PROPERTIES AND WHEN THEY CONTAIN FIBER-REACTIVE SUBSTITUENTS, THE AZOPYRIMIDINE DYESTUFFS CAN ALSO BE USED FOR THE DYEING OF CELLULOSE FIBERS ON WHICH THEY AFFORD DYEINGS HAVING GOOD WET-FASTNESS PROPERTIES, ESPECIALLY FASTNESS TO WASHING.
