Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a sublimation transfer ink consisting of a sublimation dye, a binder, a solvent, and an additive to imprint a desired pattern onto a transfer paper base such as paper or a synthetic resin film. create and
The present invention relates to a sublimation transfer method, which involves bringing the transfer paper and the object to be transferred into close contact with each other and heating them to sublimate the sublimable dye, thereby forming a desired pattern on the object to be transferred.

The sublimation transfer method is a transfer method that has been known as a method for forming patterns on cloth, paper, film, etc. For example, as disclosed in Japanese Patent Publication No. 39-18793, sublimation dyes such as triphenyl Dyes such as methane dye bases, disperse dyes, smoke dyes, organic solvent soluble dyes, and oxidation dyes are used as pigments, and as binders, they are light and heavy and are difficult to dye with sublimable dyes, and the melting point or softening point of the sublimable dyes. Using a binder with a higher melting point or softening point, such as sizing for textile printing, and using water or a suitable organic solvent as the solvent, appropriate amounts of the sublimable dye, binder, and solvent are kneaded in a ball mill or the like. Prepare an ink, use this ink to form a desired pattern on a transfer paper base such as paper or synthetic resin film using an appropriate printing method to make a transfer paper, and then combine the thus obtained transfer paper with the cover. The transfer paper is overlapped with the transfer paper, heated, and pressure is applied as necessary to sublimate the sublimable dye contained in the transfer paper.
This is a method in which the sublimated vapor is solidified on the object to be transferred to create a pattern on the object.

Furthermore, as an improved method of this type of method,
As disclosed in No. 21602, there is also a method of using a transfer paper in which a sublimable dye-containing ink layer is formed on a transfer paper base, and a heat-sensitive adhesive containing a thermoplastic resin as a main component is applied thereon.

In addition to the known sublimation transfer method, the present invention uses one or more sublimable blue dyes that have a fast sublimation transfer speed and one or two or more sublimable blue dyes that have a slow sublimation transfer speed. The present invention relates to a new transfer method in which transfer is performed using a sublimable mixed blue dye obtained by mixing.

Conventionally, a temperature range of 190 to 200°C has been generally adopted as a suitable transfer temperature condition, but known sublimation blue dyes include blue dyes with a fast transfer speed that complete sublimation transfer at 190°C or less. Only blue dyes that undergo sublimation transfer at temperatures above 210° C. and have a slow transfer rate have been found.

However, the former sublimation dye, which has a fast sublimation transfer speed, has extremely poor light resistance of the transferred design applied to the transferred object, and when the latter sublimation dye, which has a slow sublimation transfer speed, is used, it is difficult to change the transfer temperature. Since high temperatures must be employed, there are drawbacks such as having an adverse effect on the material of the object to be transferred, and, for example, significantly impairing the feel of the polyester fiber used as the object to be transferred.

As mentioned above, among the various dyes currently used for sublimation transfer, there are no blue-based dyes that have a fast sublimation transfer speed and good fastness, even among domestic and foreign dye manufacturers. In the field of sublimation transfer, the green and sepia colors that are used in the sublimation transfer field suffer from blurred hues and specks due to even slight temperature and pressure fluctuations in the transfer machine.

As a result of various studies to solve these problems, the inventors of the present invention have found that blue dyes, which originally have a fast sublimation transfer speed but poor light fastness, have been replaced with blue dyes that have a slow sublimation transfer speed but have poor fastness. By mixing good blue dyes, dyes that originally have a slow sublimation transfer speed can be used.

The present inventors have discovered that it can be used as a dye that has a fast sublimation transfer rate and excellent fastness, and has completed the present invention.

The blue sublimable dye obtained by the method of the present invention has a fast sublimation transfer speed and excellent light resistance, and can be fully used as a blended dye. This solves problems such as blurring of hues and specs of patterns in series and sepia series, and has an extremely large contribution to the improvement of technology in this field.

The dyes with high sublimation transfer speed used in the present invention include:
It is a derivative of anthraquinone, and is a dye represented by the general formula having an alkylamino group such as a methylamino group or an ethylamino group at the 1 and 4 positions.For example, 1,4-bis-methylaminoanthraquinone, Examples include bis-ethylaminoanthraquinone, 1,4-bispropylaminoanthraquinone, etc. Dyes with slow sublimation transfer speeds include amino and hydroxy derivatives of anthraquinone, such as 1°5-dihydroxy-2- Promo 4,8
-diaminoanthraquinone, 1-dimethylamino-4,
Examples include 8-dihydroxy-5-aminoanthraquinone.

In the present invention, the sublimation transfer speed is said to be high when the sublimation speed of the dye (the temperature at which the dye sublimates and exhibits its original hue and density on the transfer material) is approximately 190°C or less; The slow transfer speed means that the sublimation speed of the dye is approximately 2
Means a temperature of 10°C or higher.

Examples will be shown below to specifically illustrate the present invention.

By using 1,4-bis-ethylaminoanthraquinone, the temperature at which 1,5-dihydroxy-2-promo-4,8-diaminoanthraquinone reached its full concentration was about 210°C, whereas conventional 1,5-dihydroxy-2-promo 4,8-diaminoanthraquinone alone was used. However, the transfer temperature was lowered to 195 to 200°C, and phenomena such as color blurring of the design were significantly improved even with slight temperature fluctuations caused by the conventional transfer machine, and the fastness was also good.
