| 摘要 |
Bichromophoric methine and azamethine transfer dyes have the formula Z2-Z1-LY1-Y2 where L is a bridge member which does not permit any conjugation of pi -electrons between Z1 and Y1, Y1 and Z1 are each independently of the other aminophenylene, which may be benzofused, or heterocyclyl and Y2 and Z2 are each independently of the other benzoquinoeiminyl, which may be benzofused, or heterocyclyl.
