In this regard the accepted mechanism suggests that the dye cations bind to adjacent sites of the polymer forming a single individual compound, which is considered to arise from electrostatic interaction among neighboring dye molecules and fixed sites on polymer as a result of which they suffer effective aggregation resulting in hypochromic and hypsochromic spectral shifts in the absorption band of the dye [26].
