Description of the Related Art Conventionally, in order to display a floor of a gymnasium, passage passages of a passage, luggage storage space, etc., paint is directly applied to the floor of an aisle such as a building or a colored adhesive tape is attached. Is being done. In any case, after the coating or sticking on the floor surface, the color of the floor surface appears through this and the display becomes unclear. Therefore, it is desirable to have a concealing property for the color of the floor surface.

る。In the method of directly applying the paint to the floor surface, the displayed color is clear, but there is a problem that it takes time and money to correct the application and to repair it thereafter. When a colored adhesive tape is used, if a vinyl chloride resin base material is used as the base material of the adhesive tape, it contains halogen and thus has a problem in incineration and disposal of wastes generated during repair. The one using polyester resin has a problem that the incineration temperature of waste is high, and the one using paper as a base material has low strength, so that it cannot be used on a floor on which a person walks. It is also conceivable that a colored tape is prepared by providing a transparent base material film with a pressure-sensitive adhesive layer mixed with a pigment, but it is difficult to uniformly disperse the pigment in the pressure-sensitive adhesive.

プは、透明な延伸ポリプロピレンフイルムの片面に印刷
が施され、該印刷面に金属含有白色インク層、粘着層が
この順に積層されてなることを特徴とするものである。The concealable pressure-sensitive adhesive tape of the present invention comprises a transparent stretched polypropylene film, one side of which is printed, and a metal-containing white ink layer and an adhesive layer are laminated in this order on the printed side. It is characterized by that.

電処理を施しておくのが好ましい。The OPP film is uniaxially stretched along the line direction of the manufacturing process, that is, in the longitudinal direction, and the stretching ratio is generally about 2 to 10 times. By being stretched, the tensile strength in the machine direction is increased and the tear strength in the transverse direction is also increased. The thickness of the film is 40
The range of -60 μm is preferable, and the surface to be printed is preferably subjected to corona discharge treatment.

下とすることが好ましい。In the present invention, a transparent OPP film is colored by printing on one side thereof. Printing may be performed by ordinary gravure printing, offset printing, flexographic printing, or the like. The printing ink is preferably a urethane-based ink because the ink film is flexible and cracks hardly occur. When the thickness of the printing ink is 5 μm or more, printing is difficult at the cell depth of the gravure plate, and the ink film is destroyed by the deformation of the substrate due to the difference in cohesive force between the printing ink and the substrate. There is a risk. Therefore, the thickness of the printing ink is preferably 5 μm or less.

利である。When coloring is performed by printing in this manner, for example, a plurality of colors are used for the floor surface display.
Rather than adding a pigment to P itself and coloring it, it is advantageous to produce an adhesive tape of a plurality of colors by printing with several kinds of colored inks in order to manufacture a large number of kinds with a small amount.

ｍの範囲が好ましい。The metal-containing white ink layer laminated on the printing surface is a mixture of a metal pigment such as bronze powder and aluminum paste, and a white pigment such as titanium oxide.
The hiding property of titanium oxide and the color tone and luster of the metallic pigment appear, the hiding property is further improved, and the display effect becomes remarkable.
The mixing ratio of the metal pigment and the white pigment is preferably in the range of 3: 7 to 7: 3. If the amount of the metallic pigment is more than this range, the color becomes dark, and if it is less than this range, the color becomes whitish and no metallic luster appears. The thickness of the layer is 1-5 μ
A range of m is preferred.

Further, if the amount of the above-mentioned metal pigment is less than 10% by weight of the total pigment, the effect of exerting the hiding property and gloss is poor, and if it exceeds 30% by weight, the effect of the hiding property cannot be obtained any more. It is preferably 30% by weight or less.

Depending on the printing ink, the color of the metallic pigment may be mixed with the printing ink to some extent. In such a case, the color of the printing ink can be faithfully expressed by providing the intermediate white ink layer between the printing ink and the metal-containing white ink layer. The intermediate white ink layer contains no metallic pigment, for example, contains only titanium oxide.

Evaluation of concealment property A concealable pressure-sensitive adhesive tape of Examples 1 to 3 and Comparative Example was applied to a black film obtained by printing a black ink containing 30% by weight of carbon black pigment in a solid content on an OPP film so as to have a thickness of 3 μm. And the chromaticity from the side of the test piece is measured by a chromaticity meter (a color difference meter CR-10 manufactured by Minolta Co.
0) was used and the lightness L * value was used for the measurement. According to this method, a material having a small hiding property has a large absorption of transmitted light due to the black color of the underlayer, and thus the lightness appears to be small. The results of the above measurements are shown in Table 1.
