Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
A positive-working imaging composition comprising a polymer binder and a sensitizer effective, when exposed to activating radiation, to provide alkali solubility to said composition, characterized in that said sensitizer comprises a quinone having the structural formula: ##STR26## wherein Q is ##STR27## R 1 is H, halo, akyl, alkoxy, aryl, aralkyl, alkaryl, cyano, or a heterocyclic ring, R 2 and R 3 are individually H, aryl, alkaryl, ##STR28## where each Ar is individually aryl, aralkyl, or alkaryl or together R 2 and R 3 comprise the number of carbon atoms that complete 1 or 2 fused carbocyclic rings, R 4 and R 5 are individually alkyl, alkaryl, aralkyl, aryl, or together R 4 and R 5 comprise the number of atoms that complete a heterocyclic ring, Z is ═0 or ═NSO 2 --Ar, where Ar is defined above, R 6 and R 7 are individually H, alkyl, aryl, alkaryl, aralkyl, --OH, or together R 6 and R 7 comprise the atoms that complete a carbocyclic or heterocyclic ring.
Claim 2
Dependent Claim
167 words
A positive-working imaging composition comprising a polymer binder and a sensitizer effective, when exposed to activating radiation, to provide alkali solubility to said composition, characterized in that said sensitizer comprises a quinone having the structural formula: ##STR26## wherein Q is ##STR27## R 1 is H, halo, akyl, alkoxy, aryl, aralkyl, alkaryl, cyano, or a heterocyclic ring, R 2 and R 3 are individually H, aryl, alkaryl, ##STR28## where each Ar is individually aryl, aralkyl, or alkaryl or together R 2 and R 3 comprise the number of carbon atoms that complete 1 or 2 fused carbocyclic rings, R 4 and R 5 are individually alkyl, alkaryl, aralkyl, aryl, or together R 4 and R 5 comprise the number of atoms that complete a heterocyclic ring, Z is ═0 or ═NSO 2 --Ar, where Ar is defined above, R 6 and R 7 are individually H, alkyl, aryl, alkaryl, aralkyl, --OH, or together R 6 and R 7 comprise the atoms that complete a carbocyclic or heterocyclic ring.
