Abstract
A recording medium comprising a support having thereon a recording layer comprising an organic silver salt, a developing agent for the organic silver salt, a water-soluble binder and an antifoggant in an amount of from 10 mol % to 40 mol % based on the organic silver salt. The recording material has a long shelf life and provides a high-density image.
Claims4
A recording material comprising a support having thereon a recording layer comprising silver behenate, a developing agent for the silver behenate, a water-soluble binder and an antifoggant in an amount of from 10 mol % to 40 mol % based on said silver behenate;
- wherein the antifoggant is at least one compound selected from the group consisting of compounds represented by the following formulae (A) to (F):
- ##STR6## wherein in formula (A), Ra represents a substituted or unsubstituted aliphatic hydrocarbon group, aryl group or heterocyclic group, Y represents --CO--, --SO--, or --SO.sub.2 --, n.sub.1 represents 0 or 1, X.sub.1 and X.sub.2 each represents a halogen atom, and A represents a hydrogen atom or an electron attractive group;
- in formula (B) Rb represents a substituted or unsubstituted aliphatic hydrocarbon group, aryl group or heterocyclic group, Mb represents a hydrogen atom or a cation, and n.sub.2 represents a number selected to provide a neutral molecule;
- in formula (C), Rc represents a substituted or unsubstituted aliphatic hydrocarbon group, aryl group or heterocyclic group, Mc represents a hydrogen atom or a cation, and n.sub.3 represents a number selected to provide a neutral molecule;
- in formula (D), Rd.sub.1, Rd.sub.2, Rd.sub.3 and R.sub.4 each represents a substituted or unsubstituted aliphatic hydrocarbon group, aryl group or heterocyclic group, Md represents a cation, and n.sub.4 represents a number selected to provide a neutral molecule;
- in formula (E), Re represents a substituted or unsubstituted aliphatic hydrocarbon group, aryl group or heterocyclic group, Me represents a hydrogen atom or a cation, and n.sub.5 represents a number selected to provide a neutral molecule;
- and in formula (F), Q represents an atomic group which forms a nitrogen-containing heterocyclic group, Mf represents a hydrogen atom or a cation, and n.sub.6 represents a number selected to provide a neutral molecule.
