| titleOfInvention | Thermographic recording material with improved image density and/or image gradation upon thermal development |
| abstract | A recording material exclusive of a thermal bleachable dye comprising a support and a thermosensitive element comprising an organic silver salt, an organic reducing agent therefor in thermal working relationship therewith and a binder, characterized in that the recording material is exclusive further contains non-halide-ion-containing arylonium compound exclusive of compounds according to formula (I): <CHEM> wherein La is a valence bond or a divalent or trivalent linking group, L2 is an alkylene group, each of Ra and Rb is a hydrogen atom or monovalent substituent group, M1 is an onium ion, Ra and Rb may form a ring taken together and D is an electron donative group of atoms, with the proviso that where D is a hydrazino group which is not a part of a semicarbazido group, no oxo group is substituted to the carbon atom which is directly attached to a nitrogen atom of the hydrazine; and a recording process therefor. |
