Claims
- 1. A methyne dye having the formula: ##STR54## wherein D is (--C.tbd.C--) or (.dbd.C.dbd.C.dbd.); L is a methine linkage; m and n each represent positive integers of from 1 to 3 provided that the total number of carbon atoms in the chain -- (L).sub.m-l (D) (L).sub.n-l is an even number; G is oxygen or sulfur; R.sub.3 is selected from the group consisting of alkyl, alkoxyalkyl, hydroxyalkyl, phenylalkyl, carboxyalkyl, sulfoalkyl and sulfophenylalkyl, each containing 1 to 10 carbon atoms or from the group consisting of aryl, lower alkaryl, lower alkoxyaryl and chloroaryl, each containing 6 to 20 carbon atoms; Z.sub.1 completes a nitrogen containing heterocyclic nucleus and Q.sub.1 represents the non-metallic atoms required to complete a heterocyclic nucleus of the type used in merocyanine dyes.
- 2. The methyne dye according to claim 1 wherein Z.sub.1 is selected from the group consisting of a thiazole nucleus, an oxazole nucleus, a selenazole nucleus, a thiazoline nucleus, a pyridine nucleus, a quinoline nucleus, a 3,3-dialkylindolenine nucleus and an imidazole nucleus and Q.sub.1 represents a heterocyclic nucleus containing 5 atoms in the ring, 3 of said atoms being carbon atoms, one of said atoms being a nitrogen atom, and one of said atoms being selected from the group consisting of a nitrogen atom, an oxygen atom and a sulfur atom.
- 3. A methyne dye having the formula: ##STR55## wherein m is a positive integer of from 1 to 3; R.sub.3 is selected from the group consisting of alkyl, alkoxyalkyl, hydroxyalkyl, phenylalkyl, carboxyalkyl, sulfoalkyl and sulfophenylalkyl, each containing 1 to 10 carbon atoms or from the group consisting of aryl, lower alkaryl, lower alkoxyaryl and chloroaryl, each containing 6 to 20 carbon atoms; Z.sub.1 completes a heterocyclic nucleus selected from the group consisting of a thiazole nucleus, an oxazole nucleus, a selenazole nucleus, a thiazoline nucleus, a pyridine nucleus, a quinoline nucleus, a 3,3-dialkylindolenine nucleus and an imidazole nucleus and Q.sub.1 represents a heterocyclic nucleus containing 5 atoms in the ring, 3 of said atoms being carbon atoms, one of said atoms being a nitrogen atom, and one of said atoms being selected from the group consisting of a nitrogen atom, an oxygen atom and a sulfur atom and G is oxygen or sulfur.
