Example Embodiment

[0102] (Embodiment 1)

[0103] Next, the first embodiment of the transfer method according to the present invention will be described.

[0104] FIG. 5 is a flowchart showing the processing procedure of the transfer method.

[0105] A general description of the first transfer method by hydraulic pressure according to the present embodiment is as follows. That is, the transfer film 101 composed of the substrate 102 and the coating film layer 105 is floated on the water surface of the transfer tank 11 (S401), the substrate 102 is dissolved or swelled (S402), and the transfer film 101 is coated The activator activates the transfer film 101 (S403), and the object to be transferred is placed on the top of the transfer film 101 and immersed in the transfer tank to transfer the coating layer 105 to the object to be transferred (S404). The substrate 102 is washed off with water (S405), the transfer target body on which the coating film layer 105 has been transferred is dried, and the coati...

[0120] (Embodiment 2)

[0121] Next, the transfer method according to other embodiments will be described.

[0122] The schematic process of the transfer method of this embodiment is the same as that of the above embodiment. As shown in FIG. 5, the transfer film 101 composed of the substrate 102 and the coating film layer 105 is floated on the water surface of the transfer tank 11 (S401) , Dissolve or swell the substrate 102 (S402), apply an activator on the transfer film 101 to activate the transfer film 101 (S403), place the transferred body on the transfer film 101 and immerse it on the transfer film 101. In the printing tank, the coating film layer 105 is transferred to the transfer object (S404), the substrate 102 is washed with water (S405), and the transfer object on which the coating film layer 105 has been transferred is dried, and the transfer is hardened. Coating film on the transferred body (S406). This concludes the transfer process.

Example Embodiment

[0145] (Example 1)

[0146] Hereinafter, more specific examples than the transfer method according to the present invention will be described.

[0147] First, as the transfer film 101, a transfer film in which the surface protective layer 103 was formed by the following process was prepared. The substrate 102 was made of a polyvinyl alcohol resin film (polyvinyl alcohol resin film) with a thickness of 40 μm. The coating method (roller coating) is applied to the coating agent made of the mixture, and then dried with hot air at 80°C to form a surface protective layer 103 of about 30μm made of ionizing radiation curable resin. The above-mentioned mixture refers to acrylic A mixture of 100 parts by weight of acryl urethane-based oligomer, 15 parts by weight of acryl monomer, and 20 parts by weight of isopropyl alcohol.

[0148] Next, the transfer process will be described.

[0149] First, as shown in Fig. 9(a), the transfer tank 11 is filled with water W with a water temperature of 30...

Abstract

A coating film that upon transfer, excels in adherence and image clarity, being free from appearance defects, such as grain defect, surface rupture, pattern break and distortion. There is provided a method of transferring, comprising the steps of floating transfer sheet (101) on the water surface of transfer bath (11), applying activator (14) onto the transfer sheet (101), dipping transfer recipient (15) in the transfer bath from above the transfer sheet (101) to thereby effect transferring of the transfer sheet (101), further washing away substrate (102) with water, drying the transfer recipient (15) with coating film (105) transferred, and hardening the coating film (105), wherein in the step of applying the activator (14) onto the transfer sheet (101) to thereby attain activation, the activator is emitted through nozzle head (3) equipped with multiple nozzles to which a pressure of 0.008 to 0.040 MPa is applied, and the nozzle head (3) is traveled above the transfer sheet (101).

Description

technical field [0001] The present invention relates to a transfer method for forming a coating film layer by transferring hydraulic pressure on the surface of various molded objects, etc., and a liquid coating device used in the method. Background technique [0002] As a conventional transfer method technology, the following hydraulic transfer method has been proposed. The hydraulic transfer method includes a process in which a transfer film having a coating film layer formed on a water-soluble film floats on the water surface to be dissolved or swells when it absorbs water. The process of coating the activator on the transfer film for activation, the process of immersing the transferred body from the top of the transfer film into the transfer tank to transfer the transfer film, and the process of washing the water-soluble film with water, so that the transferred coated The step of drying the transfer target of the film, and the step of hardening the coating film transferre...
