Isocyanin:
An isocyanide is an organic compound with the functional group -N≡C. It is the isomer of the related nitrile, hence the prefix is isocyano.

It is composed of four isoindole units linked by nitrogen atoms. H2Pc has a two-dimensional geometry and a ring system consisting of 18 π-electrons. The extensive delocalization of the π-electrons affords the molecule useful properties, lending itself to applications in dyes and pigments. Metal complexes derived from Pc2−
, the conjugate base of H2Pc, are valuable in catalysis, organic solar cells, and photodynamic therapy.]]> 2020-11-20 16:29:16 UTC https://padlet.com/anithagvgvc/dx5yax61xj9la2n/wish/945958530 Leather dyeing involves application of direct and acidic dyes, most often with mordant, in alkaline, conditions.

             Basic class of dyes find application for colouring paper but other class of dye can also be used depending upon the end uses. In the case of preparation of copy papers where there is no need to have carbon paper. Basically colour forming precursors are apply to paper which are converted into parent colours by hard pressing. In photography also certain colour forming components are suitably coupled with aromatic diamines capable of getting oxidised and these are used along with the silver halide. Even in development of black and white pictures use is made of certain diazonium components along with coupling components to develop the picture from the silver halide. Example, dyes used in paper-safranine T, auromine. 
                          The dyestuffs employed in leather industry belong to acid class, metal complex class and basic class. Polyaso and azo types of dyes find applications in dying leather. Example, chrome leather black A.
