A colored curable composition including: at least one selected from the group consisting of a compound represented by the following Formula (1a) and a tautomer thereof; and at least one polymerizable compound, wherein R11, R12, R13, R14, R15, and R16 each independently represent a hydrogen atom or a monovalent substituent; and R11 and R12, and R15 and R16 independently may bond to each other in each pair to form a ring.

By condensation of squaric acid (1) with 2-(dialkylamino)-substituted thiazoles 8 a novel type of heterocyclic-substituted squaraines of the general structure 9 was prepared in moderate yield mostly.The squaraines 9 obtained are sparingly soluble in the most organic solvents and exhibit, in these solvents, narrow absorption bands in the visible range at about 620-700 nm.In dispersed form, the absorption bands of the squaraines 9 are, however, broadened and shifted into the NIR region at about 900 nm.These unique properties of the new squaraines 9 suggest the use of these dyes as spectral sensitizers for laser-driven data recording or data storage media. - Key Words: Squaraines/ Squaric acid/ Thiazoles/ Sensitizers

Compounds of the general formula I STR1 where R is unsubstituted or substituted alkyl, alkenyl, aryl or hetaryl and R1 and R2 independently of one another are each unsubstituted or substituted alkyl or aryl, or, together with the nitrogen, form a heterocyclic ring, are prepared by a process wherein a compound of the general formula II STR2 is reacted with a water-soluble monohaloacetate in an aqueous alkaline medium. They are very useful coupling components for the preparation of azo dyes.

Reaction of 1-alkynyl thiocyanates RCC-S-CN (1) with alcohols, phenol or thiols or secondary aliphatic amines in the presence of anhydrous zinc chloride or boron trifluoride diethyl etherate gives mixtures of 2,4-disubstituted 1,3-thiazoles (2), thiocarbonyl compounds (3) (thiono esters, dithio esters or thioamides) and 2-alkylidene-1,3-dithioles (4).In all cases, the 1,3-thiazoles can be obtained in good yields if the proper reaction conditions are applied.Interaction between 1 and lithium dialkylamides LiNR'2 gives the compounds RCC-S-NR'2 (5) (attack on sulfur).With alkoxides R'O1-, the primary attack is on CN: the in termediacy alkynethiolate RCC-S1- subsequently reacts with the alkyl cyanate R'OCN to afford 1-alkynyl sulfides RCC-SR'(6)
