Investigations Concerning Sensitization of Silver Free Information Recording Materials with Azo Dyes and Polyhalogen CompoundsRecording materials mentioned in the title are sensitive to the visible region of light. The reason therefore is an energy transfer from the azo dye to the polyhalogen compounds, preferentially CBr4. It's possible to separate the absorption spectra of azo compounds used in this work into two gaussian functions, which relates to n,π*- and π,π*-transitions. Only the excitation of the n,π*-transition causes sensitization. A mechanisms of sensitization is proposed.
