Paragraph 0024; 0025; 0029, (2017/08/27)
The invention discloses an active yellow dye compound containing a naphthalene structure. The structural formula of the compound is represented by the formula (I). The activity of two fluorine atoms of the compound is high, the compound can be taken as a dye with two active groups, the compound can be used to prepare a dye with a high fixation rate, and the dye does not contain any absorbable organic halogen, meets the requirements of the European AOX law, and has a good color fastness.
Active yellow-dye compound containing fluorine and preparation method thereof
-
Paragraph 0026; 0027, (2017/08/27)
The invention discloses an active yellow-dye compound containing fluorine. The structural formula of the compound is shown as a general formula (I). The active yellow-dye compound has the advantages that the activity of two fluorine atoms is also high, so that the active yellow-dye compound can be seen as a double-active-group dye, and is higher in color fixation rate; the dye does not contain absorbable organic halogen, and conforms to European AOX regulations.
