[Formula] represents a group, and X 1 represents an alkyl group or an alkoxy group. ) The tricyanovinyl compound represented by
It is a novel compound that is valuable as a dye, pigment, or an intermediate thereof. The compound represented by the above general formula [] is, for example,
Structural formula below [] (In the formula, A and X 1 have the same meanings as in the above general formula [].) It is produced by heating the compound represented by the formula with tetracyanoethylene in an organic solvent. Specific examples of X 1 in the general formula [] include alkyl groups such as methyl group, ethyl group, linear or branched propyl group, butyl group, pentyl group, heptyl group, and octyl group; Examples include alkoxy groups such as methoxy, propoxy, butoxy, and octoxy groups. The compounds of the present invention are novel red and blue pigments, and are not only useful as coloring agents for various synthetic fibers, plastics, and other materials, but are also extremely valuable as intermediates for various dyes and pigments. In particular, this compound has an excellent affinity for hydrophobic materials compared to known tricyanovinyl compounds, and is useful for coloring low-molecular materials such as liquid crystals, synthetic resins such as polystyrene and polyacrylic acid esters, and polyester synthetic fibers. Suitable for dyeing. Next, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited to the following Examples. Example 1 Structural formula below Dissolve 3.65 g of the compound shown in 20 ml of N,N-dimethylformamide (DMF) and add 1.28 g of tetracyanoethylene. This solution is stirred at 70-80°C for 1 hour. Then, after cooling to room temperature, add 60ml of water.
dilute with water to precipitate crystals. The obtained crystals were filtered, washed with water, dried, and purified by column chromatography to obtain the following structural formula. A dye shown in was obtained. This dye is 155.5℃~156.3
The melting point was shown in °C. 100 g of polyester fiber was immersed in a dyeing bath in which 0.5 g of this product was dispersed in 3 water containing 1 g of naphthalene sulfonic acid-formaldehyde condensate and 2 g of higher alcohol sulfate, dyed at 130°C for 60 minutes, then soaped, washed with water and After drying, a vivid blue dyed cloth was obtained. Furthermore, when polystyrene resin was colored using this product, a polystyrene resin plate colored bright blue was obtained. Example 2 The following structural formula used in Example 1 Instead of the compound represented by the following structural formula The following structural formula was prepared in the same manner as in Example 1 except for using compound 3.68 represented by A dye shown in was obtained. This dye is 131.0℃~131.5
The melting point was shown in °C. 100 g of polyester fiber was immersed in a dyeing bath in which 0.5 g of this product was dispersed in 3 water containing 1 g of naphthalene sulfonic acid-formaldehyde condensate and 2 g of higher alcohol sulfate, dyed at 130°C for 60 minutes, then soaped and washed with water. After drying and drying, a vivid purple dyed cloth was obtained. When this product was blended with polystyrene resin and injection molded using a conventional method, a bright purple colored polystyrene resin plate was obtained. Example 3 The following structural formula used in Example 1 Instead of the compound represented by the following structural formula Except for using 3.52g of the compound shown in
By the same operation method as in Example 1, the following structural formula A dye shown in was obtained. This dye is 85.5℃~86.5℃
It showed a melting point of 100 g of polyester fiber is immersed in a dyeing bath in which 0.5 g of this product is dispersed in 3 water containing 1 g of naphthalene sulfonic acid-formaldehyde condensate and 2 g of higher alcohol sulfate, dyed at 130°C for 60 minutes, then soaped and water dyed. After drying, a bright magenta dyed fabric was obtained.
When polystyrene resin was colored using this product, a polystyrene resin plate colored in a bright mangenta color was obtained. Example 4 Table 1 shows the tricyanovinyl compound of the present invention and its maximum absorption wavelength.
