Definitions

• the present invention relates to a pressure-sensitive recording and transfer material which in a first sheet has a coating comprising one of components (A) and (B) or a solvent for these components and in a second sheet the other component or both components (A). and (B) and contains an electron attractive and color developing material as component (C), wherein (A) a polycyclic compound of the formula is what X is a monocyclic or polycyclic aromatic or heteroaromatic radical, Y is a substituent that can be split off as an anion Q2 -CH2-, -CO-, -CS- or -SO2- and R is hydrogen, C1-C12-alkyl, C5-C10-cycloalkyl, aryl, such as phenyl or aralkyl, such as benzyl and the ring A is an aromatic or heterocyclic radical with 6 ring atoms, which may have an aromatic fused ring, both the ring A and the fused ring can be substituted and (B) represents an organic condensation
• Components (A), (B) and (C) come into contact with each other by pressure and leave records on the developer sheet.
• the color is produced in accordance with the type of components (A) and (B), which represent the electron donor and form the chromogenic part.
• the color formation is caused by component (C).
• you can the desired colors, such as yellow, orange, red, violet, blue, green, gray, black or mixed colors are generated.
