Transfer-printing method and printed article

Abstract

The invention provides a transfer-printing method and a printed article. The transfer-printing method includes a transfer paper preparing step, a transferring step, and a releasing step. The transferpaper preparing step involves forming an image using transfer-printing ink containing a pigment and a fixing resin by ejecting the ink onto a transfer paper base and then drying at a temperature lowerthan the cross-linking temperature of the fixing resin to obtain transfer paper. The transferring step involves transferring the image formed on the transfer paper to cloth by pressing, while heatingat a temperature higher than the cross-linking temperature of the fixing resin. The releasing step involves releasing the transfer paper from the cloth having the image fixed to it. The layer thickness of the ink layer formed on the transfer paper base is 50 nm to 500 nm, and, in the transferring step, the ink layer is transferred in the form of film to the surface of the cloth.

Description

technical field [0001] The present invention relates to a transfer printing method for transferring an image recorded on transfer paper by an inkjet recording device to a recording sheet, and to a printed matter produced by the method. Background technique [0002] Conventionally, screen printing, roll printing, and the like have been widely used as methods of printing on fabrics such as cotton, silk, and polyester. Since these printing and dyeing methods require the preparation of screen frames, engraving rollers, etc. for each pattern, they are not suitable for printing and dyeing of many varieties and low-volume production. In addition, paste and the like need to be washed away, and a large amount of waste water is discharged, which poses a problem of increasing environmental load. In contrast, the inkjet printing method does not require plate making operations such as screen frames and engraving rollers, and can change patterns and colors only by changing digital data. ...

AI Technical Summary

Problems solved by technology

[0007] However, the sublimation printing method has the following problems: it can only be applied to polyester fibers; since the sublimation dye has a small molecular weight, depending on the dye, there is a possibility of weak light fastness, color transfer and fading due to washing and heat from an iron ; and due to the high transfer temperature, the fibers are compressed during transfer, which damages the hand feeling; etc.
