Compound and process for poducing dye

Abstract

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)].
