Description

[Detailed description of the invention] The present invention relates to basic dye compositions.

Basic dyes are well known as dyes that can completely dye basic dye-dyable polyester, polyacrylonitrile fibers, and the like. Although basic dyes have excellent dyeability, they have the problem of contaminating the equipment during dyeing, and they are also used for blended fabrics, blended fabrics, etc. of polyester fibers dyeable with basic dyes and fibers dyeable with acid dyes, such as wool. When dyeing, it is necessary to use a basic dye and an acidic dye completely mixed together, and in such a case, since both dyes have an opposite ionic relationship, a problem called aggregation of the dyes occurs. .

In order to solve problems such as equipment contamination during dyeing, we have investigated the problems between water-soluble basic dyes and anionic dispersants (condensates of naphthalene sulfonic acid and formalin, sulfonated products of lignin and lignin hyperconductors, etc.). A basic dye dispersion in which a soluble dye complex salt is finely dispersed with an excess of an anionic dispersant has been proposed (Japanese Patent Publication No. 3 Ku1-7da No. 7, No. 57-qtlIo).
No., same &? -G23 da issue, etc.).

The present invention provides a basic dye composition that does not cause equipment contamination during dyeing and has excellent level dyeing properties, dyeability, etc. for blended fabrics, blended fabrics, etc. with basic dye dyeable fibers and acid dye dyeable fibers. Its purpose is to provide the following.

That is, the present invention provides a basic dye and the following general formula [1]
A basic dye composition containing an anionic surfactant represented by:

General 2m (in the formula, represents the number of kij/~koSθO, and M is
The gist is Ha%NH, which represents an alkylamine.

In the above general formula [■], when k is l, t means styrene sulfonate, but when it is - or more, it is generally produced as a mixture, and especially when the number is small, what is the restriction on the terminals? It is unknown whether there are any.

Examples of the alkylamine include methylamine, dimethylamine, diethyl, and the like.

As M, Na is preferable.

Examples of the styrene sulfonic acid polymer represented by the above general formula (1) include homopolymers of styrene sulfonate and copolymers of styrene sulfonate and styrene.

The method for producing styrene sulfonate is as follows:
After sulfonating styrene with concentrated sulfuric acid, an alkaline agent (
It can be easily obtained by neutralizing with caustic soda, aqueous ammonia, dimethylamine, etc.).

In addition, a polymer of styrene sulfonate can be easily produced by neutralizing polystyrene sulfonic acid obtained by normal radical polymerization (bulk polymerization or solution polymerization) with an alkali agent to form polystere/sulfonate. You can get a lot of money. In this case, the degree of polymerization may be adjusted by appropriately selecting the type of polymerization initiator, polymerization temperature, solvent, etc.

The range of S to J, zero-fold fluorophores can be mentioned.

If necessary, water or a hydrophilic organic solvent such as ethylene glycol, globylene glycol, methanol, etc. can be used. It is also possible to add nonionic surfactants, such as ethylene oxide adducts of β-7-tole, to stabilize the dye composition.

In the composition of the present invention, the dye and the anionic surfactant have a combined content of usually 1.2 o wt96 or more, preferably 1

It can be produced by slurrying it with water or a hydrophilic organic solvent and gradually adding an anionic surfactant while pulverizing it using a wet grinder (sand mill, ball mill, homomixer, etc.) according to a conventional method. can. Furthermore, if necessary, it can be manufactured by adding a nonionic surfactant, etc., then adjusting the pH to usually 7 to 7, adjusting the dye concentration and color tone, and then pulverizing it slightly. .
