Reaction Steps

Component D: A mixture of 5-bromo-4-hydroxy-6-methyl-1,3,3a,7-tetraazaindene, water, and 2.5N NaOH was placed in a beaker and heated to 50° C. to dissolve the materials and form Compound TAI-1. A mixture of boric acid and the indicated thermal solvent was dissolved in water by heating at 50° C. The solution was cooled to room temperature and a portion of deionized lime-processed gelatin was added to the solution to be hydrated for 30 minutes. The mixture was heated to 40° C. for 10 minutes to melt the gelatin. A portion of a dispersion of 6.5 μm polystyrene beads in gelatin was placed in another beaker and heated to 40° C. for 10 minutes to melt the gelatin. The two gelatin containing subcomponents were combined and the mixture was added a 4% active aqueous solution of ZONYL® FS-300 surfactant and a portion of the Compound TAI-1 solution described above.
