    • A azomethine yellow dye compound of general formula (I): General formula (I) wherein R1 and R2 each independently represent a hydrogen atom or a substituent; R3 represents a substituent; m indicates an integer from 0 to 3; when m is 2 or greater, R3's may be the same or different and may be mutually bonded to form a condensed ring; R3 may be bonded to R1 or R2 to form a condensed ring; R4 represents an aryl group or a heterocyclic group; R5 and R6 each independently represent a hydrogen atom or a substituent; R7 represents a substituent; n indicates an integer from 0 to 4; when n is 2 or greater, R7's may be the same or different and the may be mutually bonded to form a condensed ring; R7 may be bonded to R5 or R6 to form a condensed ring; and R5 and R6 may be bonded to each other to form a ring.
    • 通式(I)的偶氮甲碱黄染料化合物:通式(I)其中R 1和R 2各自独立地表示氢原子或取代基; R3表示取代基; m表示0〜3的整数, 当m为2或更大时,R 3可以相同或不同并且可以相互结合形成稠环; R 3可以与R 1或R 2结合形成稠环; R4表示芳基或杂环基; R5和R6各自独立地表示氢原子或取代基; R7表示取代基; n表示0〜4的整数, 当n为2或更大时,R 7可以相同或不同,并且可以相互键合形成稠环; R7可以键合到R5或R6以形成稠环; 并且R 5和R 6可以彼此键合形成环。
