Wipeable inkjet dye

Abstract

A wipeable inkjet dye comprises dye A as shown in a formula (I), dye B as shown in a formula (II), dye C as shown in a formula (III), and dye D as shown in a formula (IV), wherein each of R1 and R2 isindependent ethyl or methoxyethyl; and each of R3 and R4 is independent C1-C4 alkyl. Each of R3 and R4 is independent methyl or ethyl. The dye is mainly prepared from the dye A, the dye B, the dye C,and the dye D, wherein each of R1 and R2 is ethyl and each of R3 and R4 is methyl. As an option, the weight percent content is as follows: the dye A is 1-90%, the dye B is 1-50%, the dye C is 1-60%,and the dye D is 1-80%. Compared with the prior art, the wipeable inkjet dye disclosed in the invention has the beneficial effect of high wipeable capability.

Description

technical field [0001] The invention belongs to the field of inkjet dyes, in particular to a wipeable inkjet dye. Background technique [0002] As a representative of the modern dye industry, inkjet dyes have developed rapidly in recent years. At present, the dyeing properties of inkjet dyes are not very compatible, and the hydrophilicity and lipophilicity between them are quite different, and the directness and water solubility of fibers are quite different. Precipitation will cause stains, and the affinity to fibers is also quite different, which is easy to cause color flowers, resulting in a low rate of genuine products after dyeing. To some extent, the application of reactive dyes is limited. [0003] In addition, the inkjet dyes used for outdoor walls are still somewhat lacking in wiping ability, and it is often time-consuming and labor-intensive to clean the inkjet walls. Therefore, the present invention continuously improves its functions and formulas according to m...

Problems solved by technology

At present, the dyeing properties of inkjet dyes are not very compatible, and the hydrophilicity and lipophilicity between them are quite different, and the directness and water solubility of fibers are quite different. Precipitation will cause stains, and the affinity for fibers is also quite different, which is easy to cause color flowers, resulting in a low rate of genuine products after dyeing.

To some extent, the application of reactive dyes is limited

[0003] In addition, the inkjet dyes used for outdoor walls are still somewhat lacking in wiping ability, and it is often time-consuming and labor-intensive to clean the inkjet walls. Therefore, the present invention continuously improves its functions and formulas according to market needs. , provides a wipeable inkjet dye
