Abstract:
A benzophenoxazine compound according to structural formula (I): ##STR13## alone or in combination with a counter ion thereof, wherein: R.sup.1, when taken alone, is selected from the group consisting of hydrogen, halogen, (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R', or when taken together with R.sup.2 is (C.sub.5 -C.sub.14) aryleno or (C.sub.5 -C.sub.14) aryleno substituted with one or more of the same or different W groups;R.sup.2, when taken alone, is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R', or when taken together with R.sup.1 is (C.sub.5 -C.sub.14) aryleno or (C.sub.5 -C.sub.14) aryleno substituted with one or more of the same or different W groups;R.sup.3, when taken alone, is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl and (C.sub.5 -C.sub.14) aryl, or when taken together with R.sup.3' is (C.sub.2 -C.sub.8) alkyldiyl or (C.sub.2 -C.sub.6) alkyleno;R.sup.3', when taken alone, is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl and (C.sub.5 -C.sub.14) aryl or when taken together with R.sup.3 is (C.sub.2 -C.sub.8) alkyldiyl or (C.sub.2 -C.sub.6) alkyleno;R.sup.4 is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R';R.sup.6 is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R';R.sup.7 is an aliphatic cationic chain comprising a total of about 4 to 20 non-hydrogen atoms and from 1 to 4 heteroatomic groups which are positively charred at a pH in the range of about pH 6 to pH 9;R.sup.11, when taken alone, is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R', or when taken together with R.sup.12 is (C.sub.5 -C.sub.14) aryleno or (C.sub.5 -C.sub.14) aryleno substituted with one or more of the same or different W groups;R.sup.12, when taken alone, is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R', or when taken together with R.sup.11 or R.sup.13 is (C.sub.5 -C.sub.14) aryleno or (C.sub.5 -C.sub.14) aryleno substituted with one or more of the same or different W groups;R.sup.13, when taken alone, is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R', or when taken together with R.sup.12 or R.sup.14 is (C.sub.5 -C.sub.14) aryleno or (C.sub.5 -C.sub.14) aryleno substituted with one or more of the same or different W groups;R.sup.14, when taken alone, is selected from the group consisting of hydrogen, (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R', or when taken together with R.sup.13 is (C.sub.5 -C.sub.14) aryleno or (C.sub.5 -C.sub.14) aryleno substituted with one or more of the same or different W groups;each W is independently selected from the group consisting of (C.sub.1 -C.sub.6) alkyl, --OR', --SR', --NR'R', --CN, --NO.sub.2 and --C(O)R'; andeach R' is independently hydrogen or (C.sub.1 -C.sub.6) alkyl.
