Abstract
A process for producing a phenothiazinium compound comprising the step of: reacting phenothiazine, in the presence of a halogen, with at least one amine selected from the group consisting of: wherein Z is CH2, O, S, SO2, NH, NCH3, NC2H5, NCH2CH2OH or NCOCH3, and R1 and R2 are each independently linear or branched CnH2nY.
