PROBLEM TO BE SOLVED: To obtain a new compound having a free acid form represented by a specific formula, capable of providing good print quality even in the case of a record recorded on a sheet of ordinary paper, cable of providing a recorded image in high density, excellent in water resistance and light resistance, good in stability when being preserved for a long time, and useful for inkjet recording or the like. SOLUTION: This new compound is the one having a free acid form of formula I (R1 and R2 are each H, an acylamino, OH or the like; X is an acylamino or a 1-7C alkyl; Y is a 1-7C alkoxy; Z is H, a carboxyalkyl or an aryl; n is 0 or 1), e.g. a compound of formula II. The compound is obtained by diazotizing a nitroaniline having R1 and R2 groups, coupling an aniline having X and Y groups therewith, diazotizing the product, and coupling the diazotized product with a naphthol derivative. |
