Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
141 words
A photosensitive imaging system suitable for producing an image in response to electromagnetic radiation, consisting essentially of a molecularly intimate admixture of at least one basic, aromatic amine, an organic acid having a pKa of from about 0.1 to 3.5, and an oxidizer for the basic aromatic amine, said oxidizer consisting essentially of a polymer polynitrate ester, the aromatic amine comprising a compound of the following formula: ##STR6## wherein R is an aromatic nucleus substituted either directly or by nitrogen or oxygen bonds with members of the group of hydrogen, halogen, alkyl, aryl and alkaryl groups, and X and Y are selected from the group of hydrogen, hydroxyl, provided that X and Y are not both hydroxyl, alkyl, aryl and alkaryl groups, such that said aromatic amine is relatively basic, such basicity not being substantially nullified by salt or amide formation.
