Problems solved by technology

[0009] However, sublimation transfer dyeing by the inkjet method has the following problems: the organic solvent that constitutes one of the components of the ink is volatilized by the heat when the dye is transferred, polluting the working environment, etc.
[0019] However, in sublimation transfer dyeing methods, it is generally difficult to balance the suppression of blank area contamination and the dyeing concentration, and it is considered that there is a trade-off relationship between the two
Therefore, a sublimation transfer dyeing method that has a high dyeing concentration and sufficiently suppresses contamination of blank areas has not yet been found

Embodiment 1

[0127] (Process 1)

[0128] Use a Henschel mixer to mix Almatex CPR-390 (96 parts), CI Disperse Blue 359 (14 parts), FCA-1001-NS (2 parts), and carnauba wax C1 (3 parts) at a rotation speed of 30 m / s. After 10 minutes of preliminary mixing, melt-kneading was performed using a twin-screw extruder. The obtained molten kneaded product was pulverized and classified using a pulverizer and classifier, thereby obtaining toner mother particles having a volume average particle diameter of 7.7 μm.

[0129] (Process 2)

[0130] The toner mother particles (100 parts), RX50 (1 part), R812 (1 part), and SW-100 (1 part) obtained in Example 1 (Step 1) were added to the Henschel mixer, and the Stirring was performed for 10 minutes at a rotation speed per second, and the cyan toner of Example 1 of the present invention was obtained.

Embodiment 2

[0132] (Process 1)

[0133] Except for setting the volume average particle diameter to 9.7 μm, the toner mother particles were obtained in the same manner as in Example 1 (Step 1).

[0134] (Process 2)

[0135] In place of the toner mother particles (100 parts) obtained in Example 1 (Step 1), the toner mother particles (100 parts) obtained in Example 2 (Step 1) were used, and the same as in Example 1 (Step 2). ) In the same manner, the cyan toner of the present invention of Example 2 was obtained.

Embodiment 3

[0137] (Process 1)

[0138] Instead of FCA-1001-NS (2 parts) used in Example 1 (Step 1), BONTRON was used RTM Except E-84 (2 parts), and the volume average particle size was 7.8 μm, the toner mother particles were obtained in the same manner as in Example 1 (Step 1).

[0139] (Process 2)

[0140] In place of the toner mother particles (100 parts) obtained in Example 1 (Step 1), the toner mother particles (100 parts) obtained in Example 3 (Step 1) were used, and otherwise the same as in Example 1 (Step 2). ) In the same manner, the cyan toner of the present invention of Example 3 was obtained.

Abstract

[Problem] To provide: a sublimation transfer printing method of a dry developing system, particularly a dry nonmagnetic developing system, still particularly a dry nonmagnetic one -component developing system, said sublimation transfer printing method being capable of achieving a high color depth and inhibiting the staining of non-image areas of a printed product; a printed product obtained by the printing method; an intermediate recording medium which is to be used in the printing method; and a toner. [Solution] A sublimation transfer printing method which comprises adhering a toner to an intermediate recording medium according to an electro- photographic process, and transferring the dye contained in the toner adhered to the intermediate recording medium to an object to be printed through the sublimation of the dye, wherein: the toner comprises a styrene-acryl resin, a sublimable dye and an external additive as essential components; and the external additive contains strontium titanate as an essential component. According to the sublimation transfer printing method, a high-quality printed product which has a high color depth and the non-image areas of which are not stained can be provided.

Description

Technical field [0001] The present invention relates to a sublimation transfer dyeing method for dyeing a dyed object using an intermediate recording medium to which a toner for sublimation transfer is adhered, a dyed product obtained by the dyeing method, a toner used in the dyeing method, and the use of This method of sublimation transfer dyeing is a method for suppressing contamination of the blank area. Background technique [0002] Electrophotographic dyeing methods for hydrophobic fibers represented by polyester cloth or hydrophobic resins represented by PET film can be roughly divided into two main types. [0003] That is, the following two methods: the direct method, after the toner is directly applied to the dyed object, and the dye contained in the toner is dyed by heat treatment; the sublimation transfer method, the toner is applied to the intermediate recording such as paper After the medium, the toner-imparting surface of the intermediate recording medium is superimpo...
