Selenium - arsenic -
The present invention relates to a water-based printing ink composition for preventing copying by an electrophotographic copying machine using a selenium-based photoreceptor such as antimony or a phthalocyanine-based photoreceptor.
（従来の技術）
電子写真方式の複写機は、近年益々普及しつつ
あるが、これに伴つて秘密文書などの漏洩、ある

されることが弊害となつてきている。(Prior Art) Electrophotographic copying machines have become more and more popular in recent years, but with this comes the disadvantage that confidential documents can be leaked, and banknotes and securities can be easily forged or altered. I'm getting used to it.

のできるシステムは開発されていなかつた。 In order to eliminate these harmful effects, methods using components that are transparent to visible light and develop color when exposed to light from a copying machine, such as impregnation with leuco bodies, photochromic substances, etc., or coatings containing these substances, are recommended. A method of applying a composition, a method of utilizing a metamery effect, a method of using a fluorescent dye, etc. are known. However, leuco bodies, fluorescent dyes, etc. have the disadvantage of poor weather resistance and deteriorate over time, and even if other methods are used, it is impossible to completely copy normal printed matter that is printed in dark colors on white paper. No system had been developed that could prevent it.
これらの欠点を改良するものとして、油性の結

あつた。 However, since this method uses an oil-based binder, it is difficult to write on printed documents or paper coated with this anti-copying method with writing instruments such as pencils, oil-based writing inks, water-based writing inks, and especially water-based writing inks. Even when I tried to write something like this, the problem was that I couldn't write properly because the letters would break off when I flicked them.
