摘要： Novel quinophthalone compounds, which are represented by the following formula (1): ##STR1## R.sub.1 -R.sub.5 each independently represents a hydrogen or halogen atom or a hydroxy, linear or branched alkyl, substituted or unsubstituted cycloalkyl, halogenated alkyl, alkoxyalkyl, alkoxy, nitro, amino, alkylamino, carboxyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, alkylcarbonylamino, alkylcarbonyloxy or cyano group; R.sub.6 -R.sub.17 each independently represents a hydrogen or halogen atom or a hydroxyl, alkyl, halogenated alkyl, alkoxy, nitro, amino, alkylamino, carboxyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, alkylcarbonyloxy or cyano group; m and n each stands for 0 or 1; and A represents a substituent, are yellow orange dyestuffs suitable for polarizing films. Polarizing films containing at least one of the compounds in a hydrophobic resin are excellent in polarizing performance, heat-resistant dimensional stability, moist heat resistance and the like and are extremely useful for liquid crystal display devices.
