摘要:A thermal recording material comprises a support and a thermal recording layer formed thereon, the thermal recording layer containing an electron-donating dye precursor and an electron-receiving developer that causes said dye precursor to develop a color, wherein said thermal recording layer contains vapor-phase synthesis silica, preferably, the vapor-phase synthesis silica has a specific surface area, measured by a BET method, of 50 to 200 m 2 /g and further is doped with aluminum oxide, and the thermal recording layer further contains the above vapor-phase synthesis silica and a diphenyl sulfones-bridged type compound, and the thermal recording material is excellent in anti-sticking property and image stability.

摘要:The invention relates to an ultrahigh contrast photographic material comprising a support bearing a silver halide emulsion layer, containing a hydrazide nucleating agent in the emulsion layer or a hydrophilic colloid layer, characterised in that the nucleating agent of formula (I) comprises (a) two nicotinamide moieties, which may be the same or different, which are linked by a linking group, and (b) a hydrazide moiety linked to only one of the nicotinamide moieties. The nucleator of formula (I) may be in combination with a nucleator of formula (II) which comprises a dimeric molecule comprising two monomers linked by a linking group, each monomer of which (a) may be the same or different and (b) comprises a hydrazide moiety and a nicotinamide moiety.The photographic material provides unexpectedly good nucleation in the absence of, or with reduced amounts of, booster and in a developer whose pH is variable, and further with lower chemical spread and pepper fog. When the synthesis provides both a compound of formula (I) and (II), the products can be used directly without a separation step, providing a cost advantage.
