摘要

2070409 9106035 PCTABS00005 Light sensitive recording media such as a silver halide photographic emulsion (10) or an optical recording disk or plate (50a or 50b). The photographic emulsion comprises a colloid or gel (12), and a multitude of silver halide particles (14) dispersed in that colloid. Each of these particles (16) includes at least a core (16a) surrounded by a shell (16b), one of the core and shell includes a silver halide (20c), and the other of the core and shell includes a dielectric (20a). The optical recording disk or plate comprises a solid, light reflecting or light transmitting substrate (52), a colloid (56) applied onto the substrate, and a multitude of particles (54), dispersed in that colloid. Each of these particles includes a core surrounded by a shell, and at least one of the core and shell consists essentially of a metal (20b).
