Abstract

PURPOSE:To enable the correction concealment for a better of a figure, etc., to be achieved by a method in which a paper base or a surface paper base has the surface coated layer containing white paint and film formable high molecular weight material, as main components, on the surface of a raw paper, and the surface of the surface coated layer has a specified opaqueness. CONSTITUTION:A concealable tacky adhesive tape is composed of a paper base 1, an adhesive layer 6 and a back surface-treating layer 7. A concealable adhesive sheet is composed of a surface paper base 2, an adhesive layer 6 and a release paper 8. The surface of the raw paper 3 of the paper base 1 and the surface-paper base 2 is coated with the coating liquid containing mainly the white paint of clay, kaolin and titanium dioxide, etc., and a binder in the rate of 2-6g/m<2>, as solid content, and thus a surface coated layer 4 is formed. As the binder, natural or synthetic film formable high molecular weight material such as starch or polyvinylalcohol used. A colored layer 5a is formed in coating by mixing a colorant with the coating liquid for the surface coated layer. Here, the opaqueness measured by opposing the surface of the surface coated layer 4 to a light source is made to be 95% or more. Thus, the tacky adhesive sheet excellent in concealing property is obtained.

As shown in FIG. 1, a surface coating layer 4 is formed on the surface of the base paper 3 by coating a coating liquid with a solid content of 2 to 6 fβ consisting mainly of a white pigment such as clay, kaori, titanium benoxide, and a binder. ing. As the binder, a natural or synthetic film-forming polymeric substance such as starch or polyvinyl alcohol is used. The colored layer 5a is formed by coating by mixing a coloring agent with the coating liquid for the surface coating layer. The high hiding power required by the present invention can be understood as the sum of the opacity of the fibers, white pigment, etc. that constitute these three layers, and the light absorption of the colorant. In Example 1, which will be described later, the present inventor set the surface coating layer to a coating amount of 3.5 f/-, and using a purple dye as a coloring agent, the coating amount of the colored layer was 3.5 f/II. The single-sided colored paper has a basis weight of 69. Ot/n? , opacity 98.7
It had a whiteness of 86 points. After bleaching and decolorizing the colored layer of this product, the opacity was measured to be 92.
%. Since the opacity of the base paper was 87.11, the above fact means that the white pigment was on both sides of the base paper at a total of 7 f/rr.
? The increase in opacity due to coating is about 5, whereas as mentioned on the same side, using a trace amount of dye called FCo and 02f/- increases the opacity by 6'lA or more. 5 effects were obtained. The opacity is determined according to JISP8 with the surface coating layer facing the light source.
138 is required to be 95- or more, and preferably 971 or more. In the present invention, a Photovolt photoelectric reflectometer model 670 was used. Incidentally, if measurements are made with the surface of the colored layer facing the light source, light absorption will occur unevenly, resulting in large errors. By selecting the hue of the colored layer, it is possible to obtain 100% color, which is comparable to conventional products using aluminum foil, but 98% or more is often used. There is no limit to the hue of the colored layer, but when the inventor prepared single-sided colored paper under certain conditions using various dyes and measured the opacity, it was found that red,
Each color of green, blue, brown, purple, and black was more than 95 times, and in particular, each color of blue, brown, purple, and black was 99 to 100 times. The colorant may be either a dye or a pigment, but it is preferable to use a dye because waste paper generated during the paper manufacturing process can be recovered and reused by bleaching and decolorizing it. The amount of colorant in the colored layer is 0.01 t/W? It is carried out in the range of ~ i, o f shi, but especially in the case of dyes 0.01 f shi ~ 0.05
A range of f/- is sufficient.

When a colored layer is applied, depending on the condition of the base paper, the colored layer may show through or ooze out, resulting in a significant decrease in whiteness. Possible means to prevent this decrease in whiteness include increasing the internal filler of the base paper, increasing the size, and increasing the air permeability, but in the present invention, the coating liquid has a high solid content. By using a gate roll type coater that performs coating with high viscosity, it is possible to substantially suppress a decrease in the whiteness of the surface coating layer. The gate roll coater has 6 parts as shown in Figure 3.
Outer roll consisting of a roll of books and rotating in the normal direction 13.
16. A coater of the type that uses an inner roll 12.15 to transfer the coating liquid between the rolls while applying nip pressure, and coats both sides of the base paper simultaneously with the final roll applicator roll 11.14. It is installed in the drying section of the paper machine.

Although the whiteness of medium-quality paper or lightweight coated medium-quality paper is not determined by commercial practice, the present invention suppresses bleeding when reversed, maintains the whiteness at least at the level of the base paper,
In addition, a paper base material having an opacity of 95 or higher can be obtained.
