Polyamines as Coupling Components. Chrysoidines are obtained by coupling dia-zonium salts of aniline, toluidines, or mixtures thereof to polyamine coupling components such as 1,3-phenylenediamine, 2,4- or 2,6- toluylenediamine, or mixtures of these diamines. These dyes confer muted yellow to orange shades to paper, leather, and polyacrylonitrile fibers. When they are mixed with malachite green and fuchsin, medium-fast black shades are obtained on polyacrylonitriles. A mixture of chrysoidine with Crystal Violet or Victoria Pure Blue is used to adjust the color of nigrosine hectograph inks [1]. 

Technical Observations. Michler s ketone and its homologs are important starting materials for the preparation of valuable triphenylmethane dyes such as Victoria blue B and Victoria pure blue BO. 

Victoria pure blue BO is prepared in a similar way from the tetraethyl ketone and ethyl-o-naphthylamine. 

Transorber (I) of the current invention was also epoxidized and grafted onto thiol-/3-cyclodextrin. Thereafter, the Victoria Pure Blue inclusion complex was prepared. 

Strictly the name Victoria pure blue BO applies to the choride salt.

Padday [74] advises the avoidance of dyes which may be adsoibed in a dual manner and, indeed, any dyes which may form covalent bonds with the surface, since they may be liable to selective adsorption on particular sites. They recommend the use of methylene blue BP, brilliant basic red B, crystal violet BP, victoria pure lake blue BO, orange II or solway ultra-blue. The two BP dyes can be used as bought, the rest need some pretreatment. 

Victoria blue B base cannot be crystallised. In a pure state it forms a brick-red powder M.P. 95°.
