Abstract
A method for providing a dispersion of a photosensitive silver and chlorine-containing polyphosphate in the pores of a porous 96% silica glass, and a photosensitive product thus produced, are described. The method includes introducing NaCl and KH.sub.2 PO.sub.4 into the pores using at least one liquid vehicle and at least partly removing the liquid vehicle from the pores. Thereafter, AgNO.sub.3 is introduced into the NaCl and KH.sub.2 PO.sub.4 -containing pores using an liquid vehicle before heating the porous glass support to remove remaining liquid vehicle and to react the NaCl, KH.sub.2 PO.sub.4, and AgNO.sub.3 to form a photosensitive silver and chlorine-containing polyphosphate material in situ in the pores of said support.
