Problems solved by technology

[0019] In this way, there is a problem that air bubbles cannot be eliminated
[0020] Furthermore, there is also such a problem that in the conventional method of preventing air bubbles, cleaning must be carried out, and the amount of activator actually required exceeds the amount of activator used for printing.

Embodiment approach 1

[0103] Next, Embodiment 1 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] The first transfer method by hydraulic pressure according to the present embodiment will be briefly described as follows. That is, the transfer film 101 composed of the base material 102 and the coating layer 105 is floated on the water surface of the transfer tank 11 (S401), the base material 102 is dissolved or swelled (S402), and the transfer film 101 is coated. The activator activates the transfer film 101 (S403), puts the transferred body on the transfer film 101 and dips it in the transfer tank, so that the coating film layer 105 is transferred to the transferred body (S404), The base material 102 is washed away with water (S405), the transferred body on which the coating film layer 105 is transferred is dried, and the coating film transferred on the transferred body is cur...

Embodiment approach 2

[0121] Next, a transfer method according to another embodiment will be described.

[0122] The general process of the transfer method of this embodiment is the same as that of the above-mentioned embodiment. As shown in FIG. , dissolve or swell the base material 102 (S402), apply an activator on the transfer film 101 to activate the transfer film 101 (S403), put the transferred body on the transfer film 101 and dip it in the transfer film 101 In the printing tank, the coating layer 105 is transferred onto the transferred body (S404), the substrate 102 is washed away with water (S405), the transferred body with the coating layer 105 is dried, and the hardened transfer is Coating film on the object to be transferred (S406). The above completes the transfer process.

[0123] Here, the activation step (S403) of the transfer film 101 in this embodiment will be described in detail.

Embodiment 1

[0146] More specific examples of the transfer method according to the present invention will be described below.

[0147] First, as the transfer film 101, a transfer film in which the surface protection layer 103 was formed by the following steps was prepared. On one side of the base material 102 composed of a polyvinyl alcohol resin film (polyvinyl alcohol resin film) with a thickness of 40 μm, the transfer film was rolled with a roller. The coating method (roller coating) applies a coating agent made of a mixture, and then dries it with hot air at 80°C to form a surface protection layer 103 of about 30 μm made of an ionizing radiation-curable resin. The above-mentioned mixture refers to acrylic acid. A mixture of 100 parts by weight of acryl urethane 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 ), 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...
