The photofading behaviour of thiazine dyes in sensitized acrylamide systeminduced by He Ne laser has been investigated.It is found that the photofading reactionof dyes is related to the structure of dyes and amines
and the concentrations of dyes
amines and monomer
In different concentrations of reactants
the photofading reactionof methylene blue is conformed to the first order reaction
Relation of thepolymerization rate( R)to the photofading rate(Rf)is rather complex
In someconditions
they are in coincidence with the equation of R_p∝R ̄1/2.
