Problems solved by technology

Most azo dyes have poor light fastness on fibers, and are prone to photooxidation or photoreduction reactions under ultraviolet radiation in sunlight, resulting in the breaking of the azo bonds of the dyes, fading and discoloration of dyed fibers, and affecting the service life of textiles.
There are differences in the light fastness of the two dyes in Acid Black ATT. C.I. Acid Orange 7 (grade 5) with poor light fastness after light fades more than C.I. Acid Black 1 (grade 7), resulting in blackness of dyed fibers decline, and discoloration occurs

Embodiment Construction

[0030] The present invention is further described below in conjunction with specific embodiment, but protection scope of the present invention is not limited thereto:

[0031] The preparation method of the compound described in embodiment 1, formula 3, carries out the following steps successively:

[0032] 1), in the o-nitroaniline (I) of 0.03mol, add the concentrated hydrochloric acid (the hydrochloric acid that mass concentration is 36%) and 30ml water of 12ml, above-mentioned reaction solution is joined in the reactor, after stirring at room temperature 40min, will The temperature of the system is lowered to 0-5°C, and then an aqueous solution of sodium nitrite (sodium nitrite mass concentration is 20%) is added dropwise to the reactor, and the molar ratio of sodium nitrite to the diazo component (that is, o-nitroaniline) is 1.1:1; react for 2hr (at this time, the starch potassium iodide test paper turns blue within 2s, showing excessive sodium nitrite), and finally remove ...

Abstract

The invention discloses a highly sun-proof type acid black dye composition. The composition is prepared from the following components in parts by weight: 7 parts of a component A, 3 parts of a component B, 1-6 parts of a component C, wherein the component A is C.I.acid black 1, the component is C.I.acid orange 7, and the component C is any one of Cibafast W, 2-hydroxyl-4-methoxy-5-sulfoacid diphenyl ketone, and an ultraviolet light absorber V. The mixing synergism principle of the component A, the component B and the component C is utilized; and the obtained black dye composition has a good dyeing rate and good sun-proof firmness, and is very suitable for dyeing and printing process of protein fibres.

Description

technical field [0001] The invention relates to a high lightfast acid black dye composition. Background technique [0002] Acid Black ATT is a mixture of two azo dyes, C.I. Acid Black 1 and C.I. Acid Orange 7 (mass ratio of C.I. Acid Black 1: C.I. Acid Orange 7: 7:3), commonly used in hair dyeing, paper, electrochemical aluminum, soap , wood, biology, leather, medicine, cosmetics, and can also be used to make ink. Most azo dyes have poor light fastness on fibers, and are prone to photooxidation or photoreduction reactions under ultraviolet radiation in sunlight, resulting in the breaking of the azo bonds of the dyes, fading and discoloration of dyed fibers, and affecting the service life of textiles. There are differences in the light fastness of the two dyes in Acid Black ATT. C.I. Acid Orange 7 (grade 5) with poor light fastness after light fades more than C.I. Acid Black 1 (grade 7), resulting in blackness of dyed fibers drop, and discoloration occurs. Because black dy...
