초록
A recording material which is suitable as a pressure-sensitive or heat-sensitive copying paper or recording paper by developing a color in contact with an electron-accepting material which comprises certain fluoran derivatives containing piperidino, pyrrolidino, morpholino and cycohexylamino groups.
대표청구항
▼
A method of recording by development of color, which comprises intimately contacting at least one of fluoran derivatives of the formula, wherein R is a piperidino group, a pyrrolidino group, a morpholino group, a methylpiperidino group, a cyclohexylamino group, an N-lower alkyl-cyclohexylamino group
A method of recording by development of color, which comprises intimately contacting at least one of fluoran derivatives of the formula, wherein R is a piperidino group, a pyrrolidino group, a morpholino group, a methylpiperidino group, a cyclohexylamino group, an N-lower alkyl-cyclohexylamino group or an N-benzylcyclohexylamino group; R1 is a hydrogen atom, a lower alkyl group, a substituted or unsubstituted amino group or a halogen atom; R2 is a hydrogen atom, a lower alkyl group, a lower alkoxy group or a halogen atom; R3 is a hydrogen atom, a C1-8 alkyl group, a phenyl group, a piperidino group, a methylpiperidino group, a pyrrolidino group, a morpholino group, a group of the formula X －N�4 is a hydrogen atom, a lower alkyl group or an alkoxy group, provided that R1 and R2, and R3 and R4, may be groups represented by the formula －CH=CH－CH= CH－, and, in this case, the naphthalene ring may have a and the benzene ring C atom or a substituted or unsubstituted amino group, and the benzene ring C may have 1 to 4 halogen atoms, with an electron accepting material, thereby permitting said fluoran derivative to develop a color. provided that when R is piperidino, pyrrolidino, morpholino, cyclohexylamino or N-methylcyclohexylamino, at least one of R1, R2, R3 and R4 is a substituent other than H, lower alkyl and haloGen.
