Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
A heat-development-type image recording material comprising on a support a heat-development-type image recording layer containing (a) an organic silver salt, (b) a reducing agent, (c) a binder, and (d) at least one compound of following formula [I]: ##STR9## wherein R 1 represents a hydrogen atom, a hydroxy radical or a substituted or unsubstituted alkyl, alkenyl, aryl or alkoxy radical; Y represents a sulfonyl or a carbonyl radical; and X represents a sulfur atom or ═N--R 2 wherein R 2 is a hydrogen atom, an amino radical or a substituted or unsubstituted alkyl, aryl or alkenyl radical.
Claim 2
Dependent Claim
96 words
A heat-development-type image recording material comprising on a support a heat-development-type image recording layer containing (a) an organic silver salt, (b) a reducing agent, (c) a binder, and (d) at least one compound of following formula [I]: ##STR9## wherein R 1 represents a hydrogen atom, a hydroxy radical or a substituted or unsubstituted alkyl, alkenyl, aryl or alkoxy radical; Y represents a sulfonyl or a carbonyl radical; and X represents a sulfur atom or ═N--R 2 wherein R 2 is a hydrogen atom, an amino radical or a substituted or unsubstituted alkyl, aryl or alkenyl radical.
Claim 3
Dependent Claim
19 words
