The Interaction between Photosensitive Diazoresine and SDS/SDBS

The interaction between photosensitive diazoresine and SDS /SDBS in aqueous solutions was studied by UV spectrum. The result is confirmed that the dissolubility of diazoresine has relation to the consistency of SDS/SDBS. It is discovered that the photodecomposition rate of diazoresine in SDS/SDBS aqueous solutions is faster than in aqueous solutions, but the thermaldecomposition of diazoresine in SDS/SDBS aqueous solutions is slower than in aqueous solutions. The result shows that the photosensitivity of diazoresine is increased and the heat steadibility is increased much. In addition, all of the photodecomposition and thermaldecomposition of diazoresine in aqueous solutions are the first order reactions.
