〈産業上の利用分野〉
本発明は写真を貼つたタイルの製造方法に関

る。DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a method for manufacturing tiles with photographs pasted thereon, and more particularly to a method for coating pasted photographs with a resin.
〈本発明が解決しようとする問題点〉
この技術では、例えば300μm程度の写真のよう
に厚く硬いものは特に端部がめくれ易いためにき
れいに貼り難く、又写真の厚さがニスの重ね塗り
にもかかわらず段差となつて残る。更にニスの重
ね塗り、つまり塗装仕上げには塗布と乾燥を数10
回繰返す必要があるから手間と時間がかかり、非
能率的であり、厚塗りにはおのずと限度がある。<Problems to be Solved by the Present Invention> With this technique, it is difficult to attach a thick and hard object such as a photograph of about 300 μm because the edges tend to peel off easily, and the thickness of the photograph makes it difficult to apply multiple coats of varnish. Nevertheless, a step remains. Furthermore, multiple coats of varnish, that is, coating and drying several times, are required for the paint finish.
Since it has to be repeated several times, it is laborious and time-consuming, and is inefficient, and there is a natural limit to how thickly it can be applied.
本発明の目的はこれらの欠点をすべて解消し、
しかも平滑な表面仕上げをもつ装飾タイルの製造
方法を提供することにある。 The purpose of the present invention is to eliminate all these drawbacks and
Moreover, it is an object of the present invention to provide a method for manufacturing decorative tiles having a smooth surface finish.

タイルが得られる。<Means for Solving the Problems> In the method of manufacturing a decorative tile with a photograph pasted according to the present invention, a photograph is pasted on a flat plate that has good adhesion with a photocurable resin, and then a transparent photocurable resin is applied thereon. paint. Next, the transparent sheet, which has little expansion and contraction due to temperature and is easily separated from the cured photocurable resin, is covered, the air bubbles between the flat plate and the sheet are defoamed under pressure, and the sheet is exposed to an electron beam while the sheet is attached. Alternatively, the photocurable resin is cured by irradiation with ultraviolet rays, and then the sheet is peeled off. In this way, a decorative tile is obtained in which the pasted photo is completely covered with transparent resin and the surface is smooth.

塗り重ねを行うことも出来る。<Example> After gluing a photograph 3, which is smaller than the flat plate, with adhesive 2 to a flat plate 1, which has good adhesion with a photocurable resin, a transparent photocurable resin 4 is applied to the flat plate over the photograph, and then The transparent sheet 5 can be covered. This sheet 5 is made of a material that has little expansion and contraction due to temperature and is easily separated from the photocurable resin after curing. After covering the applied resin with a transparent sheet, pressure is applied, for example by rolling, to defoam any air bubbles trapped between the sheet and the flat plate, and then electron beams or ultraviolet rays are irradiated to harden the resin. In this way, a smooth resin layer with no steps can be created at the edges of Photo 3.
In the present invention, since a transparent sheet is used, it is possible to easily determine whether or not air bubbles exist between the flat plate and the sheet, and there is no need to block electron beams or ultraviolet rays. As a sheet material, it has little expansion and contraction due to temperature. For example, polyethylene terephthalate is used. Therefore, even when the photocurable resin is cured by irradiation, the photo is not peeled off, but rather the photocurable resin layer can be formed while the photo is pressed down, and the edges of the photo are not peeled off. It never turns over. Furthermore, in the step of removing air bubbles from the sheet, the uncured resin between the photograph and the sheet becomes thinner, so that the internal stress caused by shrinkage during curing does not become large.
This also helps prevent the edges of the photo from turning over. If it is necessary to add depth to the resin, additional coats can be applied.

でもきれいな仕上げが出来る。<Effects of the Invention> According to the present invention, since a sheet is used and pressure is applied from above, an extremely smooth finish can be achieved without using a flow coater or the like.
Also, since dust does not adhere to the finished surface before the resin hardens, a clean finish can be achieved even in non-clean rooms.
