Abstract

PURPOSE:To enable fine multicolor printing and enable favorable transfer even to a rugged object surface or the link, by a method wherein a silicone-coated paper is coated with an adhesive paste, the surface of the adhesive paste is coated with a separating film formed from a powder, a foil or the like of a metal or a non-metal, and printing is conducted on the surface of the separating film. CONSTITUTION:The instant transfer sheet comprises a silicone-coated paper 1, a nondrying strong adhesive paste layer 2, an aluminum powder layer 3, a print layer 4 and a released paper 5. Printing 4 is conducted on the adhesive paste layer 2 through the aluminum powder layer 3 therebetween. Therefore, during printing, an organic matter, in a printing ink does not make direct contact with the adhesive paste, so that favorable printing operation is ensured, and only the print parts can be adhered to the released paper 5. Accordingly, it is possible to easily transfer images onto a rugged surface 6 of an automobile body or the like in a desired manner, without requiring a cutting operation, removed of unrequired parts or the like.

Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention is suitable for printing on the outer surface of automobile bodies, glass surfaces, storefronts, signboard surfaces, and other surfaces on which it is difficult to directly print. The present invention relates to a sheet-like product that can easily display characters, figures, etc., which can also be produced in a similar elaborate multicolor manner, and a method for producing the same.

``Prior Art'' Conventionally, in order to make printed-like characters or figures appear on surfaces on which it is difficult to directly print, such as the outer surface of a car body, a glass surface, a storefront, a signboard surface, etc., It is known that a film layer of any color is present on the surface of silicone paper with a glue having strong adhesion properties interposed therebetween, and the surface of the film layer is covered with release paper. ,
The user prints the desired characters, figures, etc. on the surface of the film,
or fill it in, manually or mechanically cut out the characters or figures, manually remove unnecessary parts, peel off the release paper surface from the silicone paper surface, and apply a strong adhesive to the release surface. By adhering the surface to the target vehicle body surface, etc., and peeling off the release paper, desired characters, figures, etc. are made to appear on the target surface. In this case, with the known technology, the user writes or prints the desired characters, patterns, etc. on the sheet surface, and then manually cuts them out (
(When processing a large number of items of the same shape, they can be cut out mechanically.) By cutting out necessary parts such as letters or figures, necessary parts such as letters or figures are separated from other unnecessary parts, but the unnecessary parts remain on the sheet surface. However, if these are attached to a transfer surface such as a car body surface, it will not be possible to express the desired publicity value, decorative value, etc. The operation of precisely removing unnecessary parts from the sheet surface with a needle tip or the like is truly an unimaginably complicated operation, and the user must have felt the same difficulty in using the sheet. In this case, it is very easy to achieve the desired purpose if the printing is applied from the beginning with a glue having strong adhesive strength interposed on the silicone paper surface, and the printed part is peeled off with a release paper and then transferred. However, when printing directly on the adhesive layer (because the adhesive is applied to the silicone paper surface and the adhesive is non-drying), the adhesive is applied to the printing plate surface. The material may peel off and adhere, or the plate surface may become clogged.
Otherwise, there are various problems such as the printing ink not imprinting on the paper surface, resulting in an incompletely defective printed surface, or the organic solvent of the ink mixing with the paste and changing its quality, reducing the adhesive effect. Printing on paper with a glue interposed therein has drawbacks that make it almost impossible to do so, and it has not been possible to do so.

``Problems to be Solved by the Invention'' It is an object of the present invention to provide a transfer sheet that can be printed on a silicone paper surface without any problem even in the presence of a non-drying adhesive, and that can perform the resulting transfer.

``Means for solving the problem'' Apply a glue to the silicone paper surface and cover the paste surface with an isolation film such as metal or non-metal powder or foil before printing on the core. By printing on the surface of the isolation film, even precise multi-colored printing can be performed, and by peeling it off with a release paper, there is no need for difficult operations such as cutting out and removing unnecessary parts. Without this, good transfer can be achieved as desired even on irregularly shaped object surfaces with unevenness or the like.

"Embodiments and Effects" To explain in detail the attached drawings showing an example of the implementation of the present invention in Kinzo, 1 is silicon paper, 2 is a non-drying strong adhesive layer, 3 is an aluminum powder layer, 4 is a printing layer, 5 6 is a release paper, and 6 is an object such as a car body.

The instant transfer sheet of the present invention is as shown in Fig. 1, in which printing 4 is applied on a non-drying strong adhesive layer 2, but since an aluminum powder layer is interposed between them, the printing operation is easy. In this case, there is no direct contact between the organic substance in the printing ink and the paste, allowing for good printing operation and allowing only the printed part to be adhered to the release paper from the beginning.
There is no need to perform operations such as cutting out or removing unnecessary parts, etc., and when the user provides only the desired characters or figures in the manuscript and makes an annotation, it is extremely easy to transfer the desired transcription onto the car body or other uneven surfaces, etc. It can also be easily applied.

"Effects of the Invention" By using the transfer sheet of the present invention, it is possible to print well even when printed on glue, and it does not require difficult and delicate operations such as cutting out characters, patterns, etc. and removing unnecessary parts. It is extremely effective because it can very easily make characters or patterns exactly similar to those printed on surfaces such as car bodies, store fronts, signboards, etc., which are difficult to print on depending on the condition of the object. It is.
