| titleOfInvention | Novel 2-hydroxy-3-naphthoic acid amide derivative and utilization thereof for diazo copying material |
| abstract | NEW MATERIAL:A compound of formula I (R 1 and R 2 are H or lower alkoxyl but not H at the same time). n EXAMPLE: 2-Hydroxy-3-naphthoic acid-O-ethoxybenzylamide. n USE: Useful as a blue color coupling component in diazo copying materials, having improved color fastness to light, and scarcely oxidized with time. n PREPARATION: 2-Hydroxy-3-naphthoic acid chloride of formula II is reacted with an amine derivative of formula III in a solvent, e.g. ethanol or dioxane, in the presence of an acid neutralizing agent, e.g. sodium hydroxide or potassium carbonate, at 80W90°C for 3W8hr to give the compound of formula I . The reaction is carried out using 1W2.5mol, based on one mole compound of formula I , compound of formula III. n COPYRIGHT: (C)1984,JPO&Japio |
