Abstract:
The visible absorption
spectra of two reactive dyes based on the copper phthalocyanine chromophore have been investigated as a function of
concentration, temperature, pH, ionic strength, and solvent. The persistence of isosbestic points indicates that an equilibrium
exists, over the concentration range investigated, between two forms of the dye only, namely dimer and monomer. The addition of urea exerts a relatively small
disaggregating influence on this equilibrium. On the other hand decrease in dielectric constant substantially changes the equilibrium in favour of the
monomeric species.
