照）。Conventionally, as a method of performing transfer printing on an object with a curved surface, prepare a thin film that has been printed on one side in advance, and swell the ink used for the printing on the printing layer of the film. Activate the printing layer by applying an activator containing a solvent that can be used to activate the printing layer, float the film on the liquid surface with the printing layer facing up, and lower the transfer object from above toward the printing layer to lower it below the liquid surface. There is known a printing method in which the film is settled, transferred to a transfer object by a liquid pressure, and after the transfer, the film is removed from the transfer object surface (for example, JP-B-60-50597, JP-B-60-5718). Reference).

コーティングむらが発生していることを見出した。The present inventors examined the cause of this problem and found that the cause was caused by uneven application of the activator to the print layer of the film, and that the film 5 was separated from the application roll (gravure cylinder) 3 in the application device. It was found that air bubbles 7 of the activator were generated in the sample, and that stripe-shaped coating unevenness was generated where the air bubbles were generated.

る。In the apparatus having the above configuration, when hot air is blown to the exit side of the nip portion between the application roll and the press roll by the hot air blowing device, the temperature of the activator between the application roll and the press roll rises, and the resin in the activator increases. , The internal energy of the solvent molecules increases, and the viscosity and surface tension decrease. Thereby, the generation of bubbles is suppressed, and the generation of coating unevenness is prevented.

なんら支障は生じない。It is thought that increasing the solvent content in the activator lowers the viscosity and prevents the formation of bubbles.
It affects the transferability, such as the dissolving power of the activator, and cannot be used for transfer printing. On the other hand, in the present invention, since only heating is performed, there is no change in the composition, and no problem occurs in transfer printing.
以下，本発明の好適な実施例を説明する。 Hereinafter, preferred embodiments of the present invention will be described.

The film 11 is pulled out from the roll 11A with its print layer facing down, and the activator is uniformly applied to the print layer by the application roll 15 and the press roll 17 of the activator application device 12. At this time, the hot air blowing device 18 blows hot air on the exit side of the nip portion between the application roll 15 and the press roll 17, that is, at a position where the film 11 is separated from the application roll 15. Therefore, the surface temperature of the application roll 15 (and the temperature of the activator between the application roll and the press roll) increases, and the viscosity and surface tension of the activator decrease. This suppresses the generation of bubbles at a position where the film 11 is separated from the application roll 15,
The occurrence of uneven coating is prevented. Here, the hot air blowing device 18
The heating temperature is not particularly limited,
The coating roll surface temperature is 18 to 25 when hot air is not sprayed.
The temperature should be about 25 to 40 ° C after the hot air is blown. A temperature at which such heating can be achieved may be appropriately selected as the hot air temperature, and is preferably, for example, about 60 to 120 ° C. The solvent in the activator used here has a high boiling point, such as butycellosolve (boiling point 171 ° C.), butyl carbitol acetate (boiling point 246 ° C.). Does not occur.

The transfer object 24 is pushed into the transfer liquid from above, and the activated printing layer is transferred to the outer surface of the transfer object 24 by liquid pressure. afterwards,
The film 11 is removed from the transfer object 24, washed with water, and dried. Thus, the transfer is completed.

いる。As described above, the present invention relates to an activator applicator including an application roll for applying an activator to a film and a press roll, wherein a hot air blowing device is provided on the exit side of the nip between the application roll and the press roll. Because the structure is designed to blow hot air, the temperature of the activator between the applicator roll and the press roll rises, which lowers the viscosity and surface tension, and suppresses the formation of bubbles at the point where the film separates from the applicator roll. This has the effect of preventing the occurrence of uneven coating. Further, since the composition and concentration of the activator itself are not changed at all, the transfer suitability is not affected, and the transfer painting apparatus having the activator application apparatus of the present invention is
This has the effect that good transfer printing can be performed.
