Abstract
A methine compound represented by the following formula (I): ##STR1## wherein Z.sub.1 and Z.sub.2 each represent a non-metallic atomic group necessitated for forming a five-membered or six-membered, nitrogen-containing heterocyclic ring, R.sub.1 and R.sub.2 each represent an alkyl group, X represents an inorganic anion, k represents a number necessitated for adjusting the electric charge of the molecule to zero, and n represents 0 or 1; with the proviso that when n is 1, the five-membered or six-membered, nitrogen-containing heterocyclic ring formed by Z.sub.2 is cationic, k is not zero and X represents chloride ion. The compound is useful as a spectral sensitizing dye and an antitumor agent.
