Abstract

The present invention provides an image transfer sheet which allows an image having a stereoscopic effect that is characteristic of UV printing to be transferred to objects of a wide variety of materials to which the image is to be transferred, particularly to the surface of a three-dimensional object including a curved surface, with such a finish that the image is directly printed, and which canbe manufactured by a minimum number of steps using a UV printer, a manufacturing method therefor, and an image transfer method using the image transfer sheet. An image transfer method, wherein an image transfer sheet is manufactured by a printing step for providing an image layer by printing ink, by a contactless printer, on the upper surface of a glue layer of a stick-on sheet obtained by peelably forming the glue layer on the upper surface of a release paper, and a pasting step for pasting, on the upper surface of the stick-on sheet on which the image layer has been provided, a transfer filmhaving a release property for the image layer and an easy adhesion property for the glue layer, and only the image layer is transferred to the surface of an object to which an image is to be transferred by a release paper removal step for peeling and removing only the release paper from the image transfer sheet, a pressure bonding step for pressure bonding the lower surface of the glue layer of the image transfer sheet from which the release paper has been removed to the object, and a film peeling step for peeling and removing the transfer film from the image transfer sheet pressure bonded tothe object.

Description

technical field

[0001] The present invention relates to an image transfer sheet for transferring an arbitrary image to an object to be transferred, a method for producing the image transfer sheet, and image transfer to an object to be transferred using the image transfer sheet method. Background technique

[0002] Techniques such as water transfer printing, thermal transfer printing, sublimation transfer printing, and dry transfer printing are well known as transfer printing for transferring an image to an object to be transferred. Among them, dry transfer is to temporarily bond the image layer on the substrate sheet, apply the adhesive on the back of the image layer, and transfer the image layer to the surface of the transfer object by pressing for bonding. ,This dry transfer printing does not leave any edges on the image during transfer, so it looks like it is directly printed on the transfer target object, and does not require post-processing with a cutter plotter or the...

Embodiment Construction

[0060] (first embodiment)

[0061] Next, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a sectional view showing an example of the image transfer sheet 1 according to the embodiment of the present invention. The image transfer sheet 1 has an image layer 13 between the transfer film 14 on the upper layer and the adhesive layer 12 on the lower layer, and the lower surface of the adhesive layer 12 is releasably bonded to the upper surface of the release paper 11 . In this embodiment, the image layer 13 is, for example, UV ink (ink) printed on the upper surface of the adhesive layer 12 by a UV printer, and the photopolymerization reaction is caused by irradiating UV during printing, and it is dried and cured into a thin film.

[0062] The material of the transfer film 14 will be described later. When the adhesive component of the adhesive layer 12 is an acrylic adhesive, a transparent acrylic resin is suitable. The adhesive ...
