    摘要： A photographic element is disclosed comprised of a support and, coated on the support, at least one radiation-sensitive layer. The radiation-sensitive layer contains silver halide grains including a spectral sensitizer adsorbed on the surface thereof and, intimately admixed therewith, silver halide grains free of surface spectral sensitization and having a particle size in the range of 0.15 to 0.8 micron in diameter. The photographic element exhibits improved speed without a concurrent increase in graininess.

    摘要： An optical information recording medium is disclosed which comprises a pair of substrates at least one of which has a recording layer on one side thereof and which are placed opposingly to each other so that said recording layer is positioned on the inside and are bonded to each other by adhesive layer(s) with or without spacer(s) therebetween to form a sealed structure, wherein said adhesive layer is composed of a cured adhesive material formed from (a) an epoxy resin, (b) a photolyzable organosilicon compound and (c) an aluminum complex compound, said photolyzable organosilicon compound being a silicon compound having at least one phenyl group which has at least one fluorine atom and at least one o-nitrobenzyloxy group which may have a substituent. The said photolyzable oganosilicon compound may be replaced by a mixture of (b-1) a silicon compound having at least one phenyl group having at least one fluorine atom and at least one o-nitrobenzyloxy group which may have a substituent, and (b-2) a silicon compound having at least one phenyl group having no substituents and at least one o-nitrobenzyloxy group which may have a substituent.
