A cut is made in the contour, the cut is whitened by diffuse reflection based on the exposure of the powder added to the masking sheet body, and further, the masking sheet body is adhered to the surface to be engraved with an adhesive layer. It is a method of removing by cutting the above-mentioned cut, and then sandblasting, characterized in that a masking sheet main body is a laminate of an upper layer and a lower layer thicker than the upper layer, and a powder for whitening the cut is added to the upper layer. A broken line may be used instead of the cut.
（実施例の説明） 以下、図面により本発明の実施例について説明する。(Description of Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

11 and a lower layer 12 which is thicker than the upper layer 11. For these upper layer 11 and lower layer 12, styrene-butadiene rubber, nitrile rubber, talc, clay, a filler such as calcium carbonate, a softener, a vulcanizing agent and the like are blended with natural rubber and the like, and particularly, a composition is used. In the upper layer 11, calcium carbonate was added to the rubber layer 10 so that the cut face described later could be whitened.
It is blended in a large amount of 50 to 500 parts by weight with respect to 0 parts by weight.

常５〜70μｍとすることが好ましい。According to the present invention, in order to engrave characters or the like on a surface to be engraved such as a stone material, first, in a factory, a masking sheet main body 1 is
A cut is made along the contour of the character to be engraved by a plotter with a blade. That is, a character or the like to be engraved is stored in a computer, a masking sheet is set on a plotter, a blade is attached to a pen of the plotter, and the computer moves the pen along the contour of the character or the like. In this case, it is desirable that the depth of the cut along the contour of the character or the like be shallower than the thickness of the masking sheet main body so that the bottom of the cut is connected. The thickness of the connected portion varies depending on the thickness and material of the masking sheet main body, but is usually preferably 5 to 70 μm.
マスキングシート本体に切れ目を入れると、前記の多
量配合した炭酸カルシウム粉末がその切り口に露出し、
乱反射が生じて切れ目が白色化する。When a cut is made in the masking sheet body, the calcium carbonate powder blended in a large amount is exposed at the cut end,
Irregular reflection occurs and the cut becomes white.

できる。The masking sheet which has been cut into the letters and the like in the factory is transferred to an engraving site, the separator is peeled off, and the masking sheet body is adhered to the surface to be engraved such as a stone, a glass plate, a metal plate, etc. by an adhesive layer. When the separator is peeled off, if the sea-island portion in the shape of a character or the like remains connected to the masking sheet main body, the masking sheet main body can be stuck to the surface to be engraved with the sea-island portion integrated.

る。After the masking sheet main body is adhered to the surface to be engraved, the cuts of the outline of the characters and the like are opened, and the characters and the like are removed from the masking sheet main body. In this case, if the shape of the character or the like is complicated, the shape of the sea-island portion of the character or the like is also complicated. Can be removed without fail, and the character can be easily removed without losing its shape.

輪郭の明確な文字等を彫刻できる。As described above, after the masking sheet main body is attached to the surface to be engraved and characters and the like are extracted, the granules are sprayed at a predetermined injection pressure. The upper layer to which calcium carbonate is added for whitening the cut is poor in elasticity and fragile, but since the lower layer is thicker, the lower layer can absorb the impact well and prevent the upper layer from breaking. Even if it breaks down, the contours of letters etc. can be maintained as they are because the lower layer is healthy,
Characters with clear contours can be engraved.
上記において、文字等の輪郭に沿い、切れ目に代えミ
シン目のような破線をいれてもよい。In the above description, a broken line such as a perforation may be provided along a contour of a character or the like instead of a break.
また、切れ目の形成には、トムソン刃を使用すること
もできる。In addition, a Thomson blade can be used to form the cut.
