Abstract
A composition suitable for application as a layer on a heat-developable image-pattern recording material to enhance the developability and stability thereof, comprising a silver salt of a benzotriazole, a reducing agent, a binder, at least one compound having the following Formula [I]: ##STR1## wherein R.sub.1 represents a hydrogen, an amino radical, or a substituted or unsubstituted alkyl, alkenyl or aryl radical; R.sub.2 represents a hydrogen, an amino alkyl, alkenyl or aryl radical is disclosed. The disclosed composition has improved developability.
Claims8
A heat-developable image-pattern recording material of enhanced developability and stability having on a support a heat-developable image-pattern recording layer containing
- (a) a silver salt of a benzotriazole,
- (b) a reducing agent,
- (c) a binder and
- (d) at least one compound having the following Formula:
- ##STR10## wherein R.sub.1 represents a hydrogen, an amino radical, or a substituted or unsubstituted alkyl, alkenyl or aryl radical;
- R.sub.2 represents a hydrogen, an amino, alkyl, alkenyl or aryl radical.
A heat-developable image-pattern recording material according to clai m 1 wherein an amount used in the layer of (a) is 0.5-50 mg of silver converted per dm.sup.2, of (b) is 0.05-10 moles per mole of silver salt of benzotriazole and of (c) is 0.001-10 moles per mole of silver salt of benzotriazole.
