The invention provides a compound for producing dye represented by a formula (I). [In formula (I), R1 represents an aliphatic hydrocarbon group having 1-8 carbon atoms or a cycloparaffin group with 5-8 carbon atoms, wherein the carbon atoms of the aliphatic hydrocarbon group can be substituted by an aromatic hydrocarbon group (the hydrogen atoms of the aromatic hydrocarbon group can also be substituted by alkyls with 1-3 carbon atoms or alkoxy with 1-3 carbon atoms); and Ar represents a group represented by a formula (i) (In formula (i), R2 represents an alkyl group with 1-3 carbon atoms, hydrogen atoms contained in the alkyl may be substituted by halogen atoms, m represents an integer from 1 to 5, when m represents 2 or more, a plurality of R2 may be same or different, and * indicates the bonding position with a nitrogen atom)].
Description
Technical field [0001] The invention involves a compound and its manufacturing method as useful as dyes. Background technique [0002] The dye is used in the fields of fibroma, LCD display device, inkjet and other fields to use reflected light or transmitted light to display color.As such dyes, Ruodan Ming B (A), which is widely known as a cricket skeleton, (A), (A), (A) (Hosada Toshiya "New Dye Chemistry", pp. 274, in May 1973 (Zhu) Technical News Hall). [0003] [0004] The traditional known as the above -mentioned compounds may not fully meet the solubility in organic solvents. Invention content [0005] The invention includes the invention recorded in the following [1] ~ [6]. [0006] [1] Form (i) represents compounds. [0007] [0008] [Form (i), [0009] R 1 Indicates a lipid ring -type hydrocarbon group with a carbon atom of 1 to 8 or a carbon atom of 5 to 8. The hydrogen atoms contained in the alipostere hydrocarbon group can be performed by the aromatic hydrocarbon...
