| abstract | PURPOSE:To offer a pressure-sensitive or thermosensitive recording paper, which forms a black color, excellent in water-and light-resistance, by forming a coloring layer containing a specified fluoran dervative as an electron-donating coupler on a support. CONSTITUTION:A fluoran derivative represented by formula IV is obtained by reacting 1mol of a compound represented by formula I (where R1 and R2 are H, 1-6C alkyl, alkenyl, alkoxyalkyl, benzyl or cyclohexyl, R1 and/or R2 may form a saturated ring with N; X is H or halonge; m is 1-4), 1mol of a compound represented by formula II (where R1' and R2' are the same as R1 and R2, respectively; Y is X; n is 1-4) and 1mol of a phenol derivative represented by formula III (where R3-5 are H or methyl; R6 and R7 are H, methyl or etheyl). This fluoran derivative is applied as an electron-donating coupler onto a support to produce a pressure-sensitive or thermosensitive recording paper in a conventional manner. |
