Title:
【発明の名称】銀塩拡散転写による画像形成方法
Document Type and Number:
Japanese Patent JP2663060
Kind Code:
B2
Abstract:
A film unit for use in a silver salt diffusion transfer image-forming process is disclosed. The film unit includes a light-sensitive element, an alkaline treating element, and an image-receiving element. The light-sensitive element includes a light-sensitive silver halide emulsion layer containing a light-sensitive silver halide emulsion which contains silver bromoiodide or silver bromoiodochloride having a silver iodide content of 0.5 to 3.5 mol %, wherein silver bromoiodide having a silver iodide content of 1 to 5 mol % is formed on the surface of the silver halide grains in an amount of from 3 to 10% on a silver basis after completion of chemical sensitization. The alkaline treating element contains a water-soluble iodide in an amount of from 0.3 to 3.0 mM/l and tetrahydrophyrimidinethione in an amount of from 0.3 to 3.0 mM/l. The film unit allows rapid completion of transfer images without loss of photographing sensitivity. Pitch-black images can be obtained rapidly without the need for image stabilizing treatments. A silver salt diffusion transfer image-forming process employing the film unit is also disclosed.
