COPPER PHTHALOCYANINE BENZYL SULFONE COMPOUND AND DERIVATIVE THEREOF

摘要

A copper phthalocyanine benzyl sulfone compound and a derivative thereof and an ink-jet ink composition containing the compound. The copper phthalocyanine benzyl sulfone compound has a formula (I), wherein substituents W1, W2, W3, W4 are located at beta positions of copper phthalocyanine respectively and independently, at least one of the substituents is a W5-represented group, and the other substituents can be independently selected from SO2(CH2)mSO2X. In the substituents, X is independently selected from NR1(CH2)wOH, N((CH2)wOH)2, NR1(CH2)wSO3M, NR1(CH2)wCO3M or OM, wherein n is an integer between 0 and 2, m and w are respectively an integer between 2 and 6; R1 is H, CH3 or CH2CH3; and M is H, Li, Na, K or Mu+R2R3R4R5, where R2, R3, R4, R5 are selected from the same or different H, C1-18 alkyl, cyclohexyl, benzyl or (CH2)wOH. The copper phthalocyanine benzyl sulfone compound can provide cyan dye molecules. The cyan dye molecules are added in ink to enhance comprehensive stability of the ink, and also reduce and prevent the bronze phenomenon, thereby improving print quality.
