3-substituted carbonyloxy-7-disubstituted amino-10-substituted carbonylphenothiazines |
| abstract |
3-(R-Carbonyloxy)-7-(N-R1-N-R2-amino)-10-(RCO)-phenothiazines useful as color formers, particularly in electrochromic recording systems, are prepared by the interaction of the corresponding 7-(N-R1-N-R2-amino)phenothiazin-3-one with a reducing agent to obtain the corresponding leuco compound and subsequently interacting the leuco compound with about two molecular proportions of an acylating agent. |
