Abstract
Silver halide photographic materials providing wash-off relief images and having excellent shelf life comprising a support having formed thereon at least a silver halide photosensitive emulsion layer and said silver halide emulsion layer or another hydrophilic colloid layer containing a polyhydroxy-spiro-bis-chroman tanning developing agent and a gallic acid alkyl ester is disclosed with a process forming relief images.
Claims10
A silver halide photographic material comprising a support having thereon a photosensitive silver halide photographic emulsion layer, said photosensitive silver halide emulsion layer or another hydrophilic colloid layer on said support containing a compound of the formula (I) and a compound of the formula (II):
- ##STR5## wherein R represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms and R' represents an alkyl group having 1 to 10 carbon atoms.
A process for forming relief images which comprises imagewise exposing a silver halide photographic material comprising a support having thereon at least a photosensitive silver halide photographic emulsion layer and at least one of said photosensitive silver halide emulsion layer or another hydrophilic colloid layer on said support containing a compound of the formula (I):
- ##STR6## wherein R represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, and a compound of the formula (II):
- ##STR7## wherein R' represents an alkyl group having 1 to 10 carbon atoms, and developing said imagewise exposed material with an alkaline aqueous solution.
