Claims
- 1. A compound having the structural formula ##STR8## wherein: R represents non-tertiary C.sub.1 to C.sub.12 alkyl, C.sub.4 to C.sub.8 cycloalkyl, non-tertiary C.sub.1 to C.sub.12 alkyl substituted with halogen, non-tertiary C.sub.1 to C.sub.4 alkoxy or non-tertiary C.sub.1 to C.sub.4 alkoxycarbonyl, phenyl or phenyl substituted by one to three of non-tertiary C.sub.1 to C.sub.4 alkyl, non-tertiary C.sub.1 to C.sub.4 alkoxy, nitro, halo, phenyl, cyano, or trihalomethyl;
- R.sup.1 and R.sup.2 independently represent non-tertiary C.sub.1 to C.sub.4 alkyl, phenyl, phenyl substituted by one or two of halo, nitro, non-tertiary C.sub.1 to C.sub.4 alkyl or non-tertiary C.sub.1 to C.sub.4 alkoxy, benzyl or benzyl substituted in the benzene ring by one or two of halo, nitro, non-tertiary C.sub.1 to C.sub.4 alkyl or non-tertiary C.sub.1 to C.sub.4 alkoxy; and
- R.sup.3 represents hydrogen or non-tertiary C.sub.1 to C.sub.4 alkyl.
- 2. A 1-R-4-(N-R-CO)amino-8-dialkylamino-9-R.sup.3 -imidazophenoxazine according to claim 1 wherein R.sup.1 and R.sup.2 represent non-tertiary C.sub.1 to C.sub.4 alkyl.
- 3. 1,9-Dimethyl-4-acetamido-8-diethylaminoimidazophenoxazine according to claim 2.
- 4. 1-(4-Methoxyphenyl)-4-(4-methoxybenzamido)-8-diethylamino-9-methylimidazophenoxazine according to claim 2.
- 5. 1-Phenyl-4-benzamido-8-diethylamino-9-methylimidazophenoxazine according to claim 2.
- 6. 1-Propyl-4-butyramido-8-diethylamino-9-methylimidazophenoxazine according to claim 2.
- 7. A process for preparing a compound according to claim 1 which comprises in a first step, interacting a compound having the structural formula ##STR9## with a reducing agent to obtain the corresponding leuco compound having the structural formula ##STR10## and, in a second step, interacting the leuco compound with at least two molecular equivalents of an acylating agent having the structural formula R-CO-Z in which Z represents halo or RCOO, and R, R.sup.1, R.sup.2 and R.sup.3 have the same respective meanings given in claim 1.
- 8. A process according to claim 7 in which Z represents halo.
- 9. A process according to claim 7 in which Z represents RCOO wherein R represents non-tertiary C.sub.1 to C.sub.12 alkyl.
