び偽造防止効果を期待することができる。(Background of the Invention) Securities, for example, banknotes used as a wide range of distribution means, require the highest degree of public credit, and forgery and alteration prevention measures are taken to maintain the credit. It is well known that existing banknotes are provided with an identification mark for judging authenticity and ticket type by "touch" based on tactile sense, which is an effective anti-counterfeit measure, but as another method, By providing a security thread with a tactile identification function and embedding it in the paper layer, a new identification and anti-counterfeiting effect can be expected.

At the papermaking stage, a security thread partially having a convex ridge is inserted into the paper layer at a substantially fixed position so as not to be exposed on the surface of the paper layer, and the convex ridge of the security thread has a different thickness. It is clearly thicker than the paper thickness, and is a security paper that allows you to identify the raised state by simply touching the paper surface. Furthermore, by imparting a coloring agent or a luminescent agent to the convex raised portion, a kind of "blur" different from the coloring or emitting state when exposed on the front or back surface of the paper, that is, observing the paper with transmitted light or reflected light In this case, the security thread that exhibits a light color effect around the convex ridge is completely embedded in the paper layer without being exposed on the front surface or the back surface of the paper.

Also, the type of banknote can be determined by the number and position of the convex protrusions. Furthermore, by imparting a coloring agent to the convex portion of the security thread, "blurring" occurs with transmitted light or reflected light.
A light-coloring effect remarkably similar to the above is added, and the above-mentioned light-coloring effect is exhibited under ultraviolet light even by adding a luminescent agent.

Placing a pattern with a dot or bar pattern cut out on one side of the base film, injecting a high viscosity type commercially available vinyl adhesive into the cutout part corresponding to the raised portion,
The excess adhesive is squeegeeed off and solidified to obtain the partially convex raised base film of FIG. Further, in the case where convex ridges are partially provided on both sides of the base film, solidification is performed on each side by using the above-mentioned dot or bar-shaped cutout stencil and a vinyl-based adhesive. A base film is obtained which is partially raised on both sides of the base film. These base films are shredded to have a width of 1 mm, for example, to obtain a security thread having a convex ridge. Further, as an example of a method for producing the security thread of the present invention on a mass production scale, a screen printing method is applied to produce a base film having the above-mentioned convex ridges at portions corresponding to screen eyes, and this is used.
