In photosensitive materials for processing with heat, a combination of a bis-beta-naphthol reducing agent with a 1,3dihydroxybenzene reducing agent, such as 2,4dihydroxybenzaldehyde or 2,4-dihydroxybenzophenone, provides surprisingly increased relative speed, maximum density and exposure latitude. This combination of reducing agents can be used in photosensitive and thermosensitive materials for processing with heat. These materials can contain addenda commonly employed in photosensitive materials such as activatortoning agents, stabilizers or stabilizer precursors, sensitizing dyes and the like. |
