An object of the present invention is to provide a method for preparing a printed product in which a transfer layer of an intermediate transfer recording medium can be transfer via a transferring adhesive layer having a suitable adhesive property to either one of the transfer layer and a transfer-receiving material, and thus transferred images do not have turbulence. This objects can be achieved by providing, a method for forming a printed product through that a transfer layer bearing an image is transferred on a transfer-receiving material via a transferring adhesive layer, characterized in that the method comprises following steps. The first step is preparing an intermediate transfer recording medium comprising at least a base film and the transfer, and an adhesive layer transfer sheet comprising at least a substrate sheet and the transferring adhesive layer comprising at least an uppermost layer and a basement layer. And the second step is carrying out a first transfer step in which the transferring adhesive layer is transferred on the transfer layer bearing the image in advance, and a second transfer step in which the transfer layer on which the transferring adhesive layer is transferred, transfers on the transfer-receiving material.

The invention is directed to an information-recorded medium with easily selectable and identifiable items of information, which is virtually protected against forgery and has enhanced security against some improper use, and a method for reading such a medium. This information-recorded medium 1 includes a substrate 2 and a layer 3 with information recorded thereon by the printing of infrared absorbing ink, said layer 3 being provided on the surface of the layer 2. The printed layer 3 is provided thereon with a relief hologram-recorded layer 7 through an adhesive layer 4, said hologram-recorded layer 7 being built up of a reflecting layer 5 transparent to the infrared region and a relief hologram-formed layer 6 provided on the surface of the reflecting layer 5. For reading, the hologram-recorded layer 7 is reconstructed by visible light, while the printed layer is reconstructed by infrared light, and the medium 1 is identified on the basis of the thus reconstructed information.

摘要:
An intermediate transfer recording medium is comprised by providing a transfer portion having a receptor layer on a substrate film. The transfer portion is printed with the image and thereafter transferred on a surface of a transfer-receiving material. In the first aspect of the intermediate transfer recording medium, the transfer portion is provided with plural hologram patterns 21 with a hologram mark 22 allocated to each the hologram pattern. According to the first aspect of the invention, since an image is formed on the receptor layer through positioning process using the hologram mark and then the transfer portion is transferred to the surface of the transfer-receiving material, no joint of a print plate appears in the hologram pattern and accuracy of transfer is remarkably excellent. On the other hand, In the second aspect of the intermediate transfer recording medium, peeling strength required to peel the transfer portion from the substrate film at the time when transferring the transfer portion to the transfer-receiving material is controlled in the range of 10 to 150 gf/inch. According to the second aspect of the invention, any transfer failure such as tail-extension or chip of the transfer portion is not caused.

The reflection layer is disposed, as required, either on the same surface side of the substrate sheet as the receptor layer is disposed so as to be interposed between the substrate sheet and the receptor layer or on the opposite side of a transparent substrate sheet to the surface provided with the receptor layer. The convexo-concave pattern may comprise an interference fringe, and may be divided into plural areas. The divided convexo-concave pattern may be composed of a single or plural kinds of pattern. The receptor layer is disposed on only one surface side of the substrate sheet, and the adhesive layer and the release sheet are disposed in this order on the other surface side, as required.
摘要:
The present invention provides an intermediate transfer recording medium which is used to form an image on a transfer-receiving member and a protective layer on the image to thereby impart durability to the image perfectly and which can simply transfer the protective layer to the image with high accuracy and also provides an image forming method. In the intermediate transfer recording medium (1) of the invention, a sheet substrate (4) provided with a resin layer (5) and a transparent sheet (2) provided with a receptor layer (3) are laminated on each other such that the resin layer (5) is peelable from the transparent sheet (2), wherein a portion of the transparent sheet (2) including the receptor layer (3) is provided with half-cut treatment (6). Using the intermediate transfer recording medium (1), a transfer image is formed on the receptor layer (3) and only the image-formed portion is retransferred to the transfer-receiving member to form an image. At this time, because a portion of the transparent sheet (2) is cut at the half-cut portion (6) as the boundary, forming a structure in which the transparent sheet (2) covers the image-formed portion and the transparent sheet functions as a uniform and strong protective layer, necessary durability is imparted perfectly to the image.
