Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a sublimation transfer printing method, and more specifically, a resist dyeing ink composition containing stannous chloride is used to resist dye a part of the ink composition, and , relates to a method for sublimation transfer printing of other parts.

<Prior art> It is well known that some disperse dyes include dyes that sublimate, vaporize, or melt when heated. Ink containing these dyes is printed on a base sheet such as paper, and then layered on a fabric to be dyed. This dye sublimes by heating.

There are also methods for dyeing cloth by vaporization or melt transfer.
It is well known as the sublimation transfer printing method.

It is also known that some of these sublimable disperse dyes lose their thermal transferability due to stannous chloride, while others do not.
Publication No. 310 prints this di-tin chloride or the like on a transfer sheet to lose the thermal transfer properties of certain sublimable disperse dyes and to perform resist dyeing.

This invention relates to a method of coloring a resist ink composition by mixing another sublimable disperse dye together with stannous chloride, that is, a colored resist dyeing method.

By the way, the resisting effect of stannous chloride is due to the fact that stannous chloride reduces the dye, but at this time hydrogen chloride is generated, which damages the transfer paper, dyed fabric, and transfer equipment, and also damages the transfer process in the first place. It has been confirmed through research by the present inventors that at high temperatures (180 to 230 U), stannous chloride releases hydrogen chloride and easily loses its reducing power (and a sufficient resisting effect cannot be obtained).

Problems to be Solved〉 The present invention was made under the circumstances as described above.
To provide a method that can perform good resist dyeing using stannous chloride without damaging transfer paper, cloth to be dyed, and a transfer device, and can also perform sublimation transfer printing of other parts well.

Means for Solving the Problems> That is, the present invention provides transfer paper printed with an ink containing a sublimable disperse dye that is reduced by stannous chloride, organic bentonite, and amines. Partially printed with a resist ink composition containing
A sublimation transfer printing method is provided, which is characterized in that a portion other than the portion printed with the resist ink composition is dyed by heating.

In the present invention, examples of sublimable disperse dyes reduced by stannous chloride include C,1,DisperseY

C011, Disperse Red 1, C, I
, Disperse Blue 106, etc.

Methods for producing transfer paper by printing on a substrate such as paper with ink containing such a dye are well known, and for example, gravure printing can be used.

Furthermore, the organic bentonite referred to in the present invention refers to one in which an organic amine is substituted with bentonite, and examples of such amines include trimethyloctadecyl ammonium chloride.

Further, the amines that are mixed into the resist ink composition together with stannous chloride and organic bentonite include, for example, ethylenediamine.

In addition, other additives to the resist ink composition include binders such as guar gum, solvents, metal soaps, etc. From the viewpoint of resist dyeing effects, it is desirable to add metal soaps.

Furthermore, when colored resist dyeing is desired, a sublimable disperse dye that is not reduced by stannous chloride can be added and mixed into the resist ink composition. Examples of such sublimable disperse dyes include C, I, Disperse Yellow
99, C, 1, Disperse Orange 3
2, C, I, DisperseRed 91,
C, 1, Disperse Red 92, C0I
, DisperseViolet 26, C11,D
Isperse Blue 56 etc. can be exemplified.

Screen printing is preferable for printing this resist ink composition on a fabric to be dyed, and as the fabric to be dyed, fibers that can be dyed with disperse dyes, such as polyester woven or knitted fabrics, can be used. Further, the transfer is performed in the same manner as the conventionally well-known sublimation transfer printing method (by heating at about 180 to 260C).

Effect> The reason why the resist ink composition according to the present invention is excellent in its resist dyeing effect is as follows.

1) Organic bentonite and metal soap absorb oily substances such as disperse dyes that migrate during transfer and organic solvents generated from printing ink on transfer paper, producing solid or gel-like substances. This prevents dye penetration and is essential for stannous chloride to exert its reducing power.

2) Organic bentonite and amines capture hydrogen chloride generated from stannous chloride, and also supply hydrogen chloride to the stannous chloride, which has lost its reducing power by generating hydrogen chloride, thereby giving it additional reducing power. Surprisingly, organic bentonite and amines prevent stannous chloride from losing its reducing power at high temperatures.

In this way, organic bentonite exhibits the double resisting effect of preventing dye penetration and preventing loss of reducing power of stannous chloride, and as a result, effective and good resisting is possible.
