| titleOfInvention | Thermal recording or pressure-sensitive recording sheet based on fluoran compound |
| abstract | PURPOSE: To provide a thermal recording or pressure-sensitive recording sheet, which has excellent color density, color-forming sensitivity, and shelf stability in an undeveloped state, by using a specified fluoran compd. as a color former. n CONSTITUTION: A thermal recording or pressure-sensitive recording sheet based on a fluoran compd. of formula I [wherein R 1 is H; 8C or lower alkyl, cycloalkyl, alkenyl, alkoxyalkyl or alkoxyalkoxyalkyl; ethyl substituted with Cl, Br, OH or phenoxy group at the β-position; phenyl or benzyl which may be substituted with Cl, Br, methyl or methoxy group with the proviso that at least one of R 1 is always a group other than H; R 2 is H, Cl, methyl; R 3 is a group of formula II III (R 4 is 8C or lower alkyl; phenyl which may be substituted with Cl, Br, methyl or methoxy) or a group of formula IV (wherein R 5 is R 1 or a group of formula V); the group of formula VI is a benzene or naphthalene nucleus] as a color former. n COPYRIGHT: (C)1984,JPO&Japio |
