Synthesis of new types of pyrazolo (4,3-d)-benzoxazine/quinoxaline cyanine dyes covering dimethine, mono (di)-cationic styryl, azastyryl and merocyanines were achieved by interaction of 3-methyl-l-phenyl pyrazolo (4,3-d)-benzoxazine/quinoxaline with active carbonyl components. The newly synthesized dyes were identified by spectral data.

Keywords: Heterocyclic dye series, pyrazolo (4, 3-d)-benzoxazine/quinoxaline cyanine dyes, spectral data
