しインキから成るすかし画像。 A watermark image comprising a watermark ink having the same hue as the base material and containing a matting agent and a surface modifier selected from pulp powder, cellulose powder, synthetic resin fiber powder, and paper powder.
該基材と異なる色相のすかしインキから成る
有色画像。 A colored image made of watermark ink of a different hue from the base material.
以下、図面を参照にして本考案を詳細に説明す

る）、合わせて隠蔽効果を高める（インキの不透
明度を高める）ための調整剤である。 Watermark image 3 is formed using a watermark ink made by kneading a matting agent and a surface modifier in a vehicle to have the same hue as base material 2, and its existence is only visible when observed under transmitted light. can now be confirmed. The matting agent and surface modifier contained in the watermark ink and the fluorescent watermark ink described below bring the surface condition of the watermark image 3 closer to that of the substrate 2 (the watermark image 3 and the fluorescent watermark ink) It is an adjusting agent for making the watermark images 4a, 4b and the base material 2 indistinguishable) and for enhancing the hiding effect (increasing the opacity of the ink).

使用した場合、すかし画像３の厚さ及びすかし画
像３表面の光散乱能と凹凸感を増加できるため、
すかし画像３の隠蔽力及び基材２表面との同一化
がより促進される。 Specific examples of the matting agent include substances that can roughen the surface of the watermark image 3, such as fine powders such as inorganic substances and pigments, or fine microparticles. Among these, foamed capsules, which are made by covering the surface of a chemical or physical foaming agent with a resin film, have good wettability with the vehicle in the ink because the surface is covered with a resin film, without impairing the printability of the ink. Moreover, it is excellent because it makes the surface of the ink film matte. In addition, when a foaming agent is used as a matting agent, the thickness of the watermark image 3 and the light scattering ability and unevenness of the surface of the watermark image 3 can be increased.
The concealing power of the watermark image 3 and its matching with the surface of the base material 2 are further promoted.

使用すればよい。 In addition, the surface modifier is a conditioner added to the ink to bring the surface condition of the watermark image 3 closer to that of the base material 2, making it difficult to see the presence of the image when observed under reflected light irradiation. Yes, pulp powder,
Selected from cellulose powder, synthetic resin fiber powder, and paper powder. This surface improving agent needs to be selected according to the type of base material 2. For example, when using natural fiber paper as the base material 2, pulp powder or cellulose powder is used as the surface modifier, and when using synthetic paper as the base material 2, synthetic resin fiber powder or synthetic paper is used as the surface modifier. Paper powder formed into a shape may be used as a surface modifier.
すかしインキはこのような組成であるため、こ
のインキによつて形成してあるすかし画像３は透
過光照射下でのみその存在が確認でき、あたかも
基材２中にすかし画像が漉入られているように感
じられる。 Since the watermark ink has such a composition, the existence of the watermark image 3 formed with this ink can be confirmed only under irradiation with transmitted light, and it is as if the watermark image has been filtered into the base material 2. I feel like I'm being held back.

可能となる。 On the other hand, the fluorescent watermark images 4a and 4b are formed with fluorescent watermark ink, and like the watermark image 3, their presence can be confirmed only under irradiation with transmitted light. In this fluorescent watermarking ink, the aforementioned matting agent and surface modifier are added for the same purpose, and a fluorescent substance is also added.
The hue was adjusted to be the same as that of base material 2.
Therefore, the watermark image 3 and the fluorescent watermark images 4a and 4b cannot be distinguished under incandescent bulbs, fluorescent lamps, or sunlight, and can only be distinguished when irradiated with radiation that causes the fluorescent substance to emit light. becomes. In FIG. 1, different fluorescent substances are present in each of the fluorescent watermark images 4a and 4b. If this is done, the colors of each fluorescent watermark image 4a, 4b will be different even if the same radiation is irradiated, or the colors of each fluorescent watermark image 4a, 4b will be different only when different types of radiation are irradiated. This makes it possible to confirm.
また、本考案の画像形成体１においては、前記
した構成の各すかし画像を基材２上でより目だち
にくくする目的で、基材２とは色相の異なる通常
のインキから成る地紋や細紋等の有色画像５を前
記各すかし画像と組合せて形成しておく。 In addition, in the image forming body 1 of the present invention, in order to make each of the watermark images having the above-described structure less noticeable on the base material 2, a ground pattern or background pattern made of ordinary ink having a different hue from the base material 2 is used. A colored image 5 such as a fine pattern is formed in combination with each of the watermark images.
前記した各画像は手書きや平版印刷方式、凸版
印刷方式、凹版印刷等の印刷方式により形成すれ
ばよく、形成方法は特に限定されない。 Each of the above-mentioned images may be formed by handwriting or by a printing method such as a planographic printing method, a letterpress printing method, or an intaglio printing method, and the forming method is not particularly limited.
第２図は叙上のような構成の画像形成体１０中

合せとして観察される。 FIG. 2A shows the state of an image observed when the image forming body 10 is irradiated with sunlight, incandescent light, or the like. Under these conditions only a colored image 15 consisting of normal printing ink is perceptible. FIG. 2B shows the state when the image forming body 10 is observed through sunlight or incandescent light, and shows the colored image 1.
5 along with the word "PRINT" are recognized.
FIG. 2C shows the state of each image observed when the image forming body 10 is irradiated with ultraviolet light while being exposed to sunlight or incandescent light. Under this condition, the fluorescent watermarks 14a and 14b develop different hues,
Under the conditions shown in FIG. 2B, what was observed as one type of watermark image is now observed as a combination of three different types of watermark images.
本考案は以上のような構成なので次のような効
果を有する。 Since the present invention has the above configuration, it has the following effects.
すかし画像はすかしインキで、螢光すかし画
像は螢光すかしインキで形成してあるため、螢
光物質を発光させる放射線を照射したときのみ
各すかし画像を区別することが可能となる。 Since the watermark image is formed with watermark ink and the fluorescent watermark image is formed with fluorescent watermark ink, it is possible to distinguish each watermark image only when the radiation that causes the fluorescent material to emit light is irradiated. Become.
各すかし画像をすかしインキで形成するた
め、すかし画像を階調豊にしかも位置精度良好
に表現できる。 Since each watermark image is formed using watermark ink, the watermark image can be expressed with rich gradation and excellent positional accuracy.
基材上で観察される画像は、透過光で観察す

察する場合でそれぞれ異なり、改ざんや偽造が
従来のすかしインキによる画像に比べて非常に
困難となる。 The image observed on the substrate differs depending on whether it is observed using transmitted light, reflected light, or even when it is observed using transmitted light while irradiating radiation that causes a luminescent substance to emit light, and falsification and forgery have traditionally been difficult. This is extremely difficult compared to images made with watermark ink.
