<p>NEW MATERIAL:The compound of formula I (Y is H, methyl, methoxy, acetylamino, nitro, etc.; X is acetyl, benzoyl, p-toluenesulfonyl, or 4-chloro-6-hydroxy- 1,3,5-triazin-2-yl; M<1>-M<3> are alkali metal, ammonium or amine group). EXAMPLE:The compound of formula II. USE:A dye, especially a recording agent for ink jet recording liquid. It has proper viscosity and surface tension, and gives a recorded image having high density and excellent water resistance, light resistance, abrasion resistance and resolution without causing the clogging of a fine orifice. PROCESS:The objective dye can be prepared by diazotizing the amine of formula IIIwith sodium nitrite, etc. in a dilute mineral acid such as hydrochloric acid, sulfuric acid, etc., and coupling the resultant diazo compound with the naphthol compound of formula IV.</p> |
