Spectral sensitization of a mercurous acrylate emulsion was studied by using various sensitizers; nitro compounds, cyanines, phthaleins, oxonols, acridines, phenazines and other sensitizers. Sensitivity measurements of the above 28 compounds showed that only acridine yellow was effective to extend the spectral sensitivity of the intrinsic emulsion from 340 nm to 600 m. Visible spectrum and adsorption isotherm suggested that acridine yellow adsorbed on the mercurous acrylate, as is the case with J-aggregate of cyanines on silver halides, formed the closely packed aggregates of molecules which conferred the distinguished effect on the spectral sensitization.
