Abstract
New polymethine dyes — selenonaphtheno[2,3-d]thiazole derivatives — were synthesized. It is shown that all of the synthesized dyes which have a selenonaphtheno[2,3-d]thiazole residue are more deeply colored than the corresponding 6,7-benzobenzothiazole and thionaphtheno[2,3-d] thiazole derivatives.
