It may be readily available and may also be easily forged. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a forgery-prevention printed matter capable of preventing forgery by copying by a color copying machine and preventing forgery of the forgery-prevention printed matter itself, and a method of manufacturing the same. The purpose is to:

る。An object of the present invention is to provide a semi-transparent film, an underlayer having a black color formed on the film, and a pearl pigment in the film on the underlayer. And a coating film patterned so that the concentration of the pearl pigment in the film thickness direction is different in the pattern.

干渉光が放出されることになる。According to the present invention, a pattern of a coating film in which a pearl pigment is dispersed in a film is formed on a base structure composed of a translucent film and a base layer having a black color. Thus, by observing the pattern of the coating film at different angles, two chromatic colors can be clearly observed. Furthermore, the concentration of the pearl pigment in the thickness direction is different in the pattern of the coating film. Thereby, in a portion where the concentration of the pearl pigment in the film thickness direction is high, incident light having an incident angle is reflected by many pearl pigments, so that a large amount of reflected light is emitted in a direction exactly opposite to the incident angle. . Then, an interference light having a high light intensity, which is the interference of the many reflected lights, is emitted.

積変化を観察することができる。On the other hand, in the portion where the concentration of the pearl pigment in the film thickness direction is low, the number of pearl pigments in the film thickness direction is small, so that only interference light having low light intensity is emitted. Therefore, since the intensity of the interference light varies in the pattern of the coating film, the change in the area of the pattern of the coating film can be observed by observing at different angles.

強度、耐熱性及び耐摩擦性を向上させることができる。[0010] This makes it possible to prevent forgery of the forgery-prevention printed matter by copying with a color copying machine, and also to prevent forgery of the forgery-prevention printed matter itself. Further, since the film is used as the base material, the tensile strength, heat resistance and friction resistance of the forgery prevention printed matter can be improved as compared with the case where the base paper is used as the base material.

変化をさらに鮮明に観察することができる。In the above-described forgery-prevention printed matter, the film has a parallel light transmittance of 45% or more. In the forgery prevention printed matter, the film has a glossiness of 9% or less. According to this, since the reflection of light from the film is reduced, it is possible to more clearly observe the change in the area of the two chromatic colors and the coating film pattern.

止用印刷物自体の信頼性を向上させることができる。Further, in the above forgery prevention printed matter, the coating film contains a resin material, and the resin material contains a mixture of a polyester resin and a vinyl chloride resin. When the underlayer is made of black ink, since the coating film formed thereon contains a polyester resin and a vinyl chloride resin, the adhesion between the underlayer and the coating film can be improved. When the forgery prevention printed matter is inserted into a base paper such as securities, the coating film cannot be easily peeled off, so that falsification of the securities can be prevented. In addition, since the coating film is not easily peeled off, the reliability of the forgery prevention printed matter itself can be improved.

And forming a film pattern. According to the present invention, the pattern of the coating film is printed on the base layer by intaglio printing. Since the pattern of the coating film containing the pearl pigment is formed by intaglio printing, the film thickness can be formed thinner at the end of the pattern than at the center. That is, the concentration of the pearl pigment in the thickness direction of the pattern of the coating film can be formed lower at the end of the pattern than at the center.

A mixture of a polyester resin and vinyl chloride. This pearl pigment 6a is, as shown in FIG.
It is dispersed in the thermoplastic resin 6b. The pearl pigment 6a includes a first titanium dioxide film 10 (white) coated on the surface of the mica particles 8 and a lower titanium oxide film formed by reducing the surface of the first titanium dioxide film 10a. It is composed of a film 10b (black) and a second titanium dioxide film 10a coated on the lower titanium oxide film 10b.

That is, since the pearl pigment 6a is dispersed in the thermoplastic resin 6b, the concentration (number) of the pearl pigment 6a in the thickness direction of the coating film pattern 6 is smaller than that of the end B of the coating film pattern 6. Is lower than the central part A.

Next, the operation of the forgery prevention printed matter of the present embodiment will be described. Generally, when light enters a thin film, light is reflected from the surface and the bottom of the thin film. In the pearl pigment 6a composed of mica particles coated with titanium oxide, as shown in FIG.
When observed from the exact opposite angle to the incident angle of 6,
The incident light 16 is reflected from the surface of the second titanium dioxide film 10a and the surface of the mica particles 8 by two reflected lights 14a, 1a.
The hue of the interference light 14 interfering with 4b is observed.

渉光１４を得ることができる。That is, the optical path difference between the reflected lights 14a, 14b, that is, the first and second titanium dioxide films 10, 10a
The interference light 14 of any color can be obtained by controlling the total thickness t of the first and second titanium oxide films 12. For example, when the geometric film thickness of the film thickness t (the film thickness obtained by dividing the optical film thickness by the refractive index) is 40 to 60 nm and silver, 6
Yellow at 0-80 nm, red at 80-100 nm, 120
It is possible to obtain blue interference light 14 at ~ 140 nm and green interference light 14 at 140-160 nm.

０として外部に放出される。The hue of the transmitted light 18 that does not become the interference light 14 and the hue of the interference light 14 generally have a complementary color relationship, that is,
There is a relationship that when the interference light 14 and the transmitted light 18 are combined, they become white light. Here, the film thickness t is set to, for example, the interference light 14.
When the interference light 14 has a red-purple color as a film thickness that exhibits red-purple color, the transmitted light 18 has a green hue that is a complementary color of red-purple. The transmitted light 18 transmitted through the pearl pigment 6a is scattered by the underlayer 4 and transmitted again through the pearl pigment 6a, and the scattered light 2 having a complementary color of the hue of the interference light 14, that is, a greenish color.
It is released to the outside as 0.

が得られ、干渉光１４の干渉色が強調される。At this time, since the reflected lights 14a and 14b and the scattered light 20 from the underlayer 4 have a complementary color relationship, if the light intensity of the scattered light 20 is too strong, the scattered light 20 is neutralized with the reflected lights 14a and 14b and is sharp. It becomes difficult to observe two chromatic colors. However, in the present embodiment, since the underlying structure is composed of the translucent film 2 and the underlying layer 4 having a black color, the scattered light 20 having an appropriate light intensity that does not neutralize the interference light 14 is used.
Is obtained, and the interference color of the interference light 14 is emphasized.

When observed from the front of the coating film pattern 6, for example, a green hue, which is a complementary color of magenta, can be observed.
In this manner, by observing the forgery prevention printed matter of the present embodiment at different angles, two chromatic colors can be observed.

だけである。As shown in FIGS. 2A and 2B, the thickness of the coating film pattern 6 is formed such that the center portion A is thicker than the end portion B. That is, since the pearl pigments 6a are dispersed in the coating film pattern 6, the concentration (number) of the pearl pigments in the thickness direction of the coating film pattern 6 is higher at the center A than at the end B. . Therefore, the incident light 16 incident on the coating film pattern 6 at an incident angle becomes many reflected lights 14a and 14b at the central portion A where many pearl pigments 6a are present, and is high in the direction of the angle directly opposite to the angle of the incident light 16. It will be emitted as interference light 14 of light intensity. However, since the end portion B has little or no pearl pigment 6a, only the interference light 14 having a low light intensity is emitted in the same direction.

That is, the scattered light 20 having the same light intensity is emitted from within the coating film pattern 6. Therefore, when the coating film pattern 6 having such a structure is observed from the angle of E in FIG. 2C, the coating layer pattern 6a is observed with the entire width C shown in FIG. When observed from the angle F, only the region where the concentration of the pearl pigment 6a in the coating layer pattern is high and the light intensity is high, that is, only the width D in FIG. 1 is observed.

あることが好ましい。Therefore, when the translucent film 2 is changed to another base material which easily reflects light, or when the underlayer 4 which exhibits white color is used.
Is used, since the reflection of light from the film 2 and the underlayer 4 is too strong and the interference light 14 and the scattered light 20 are canceled out, the chromatic color of two colors and the change in the area of the coating film pattern 6 are clearly observed. It becomes difficult to do. In this sense,
The transmissivity of the parallel light of the translucent film 2 is JISK7
It is preferable that the value measured by the measurement method of 105 is 45% or more. In the case where the transmittance of the parallel light of the film 2 is less than 45%, for example, when a colorless and transparent film is used, even if the black underlying layer 4 is present thereon, the reflection of light from the film increases. It is not preferable because it is difficult to clearly observe the change in the chromatic colors of two colors and the area of the coating film pattern 6. The gloss of the film 2 is
The value measured by the measurement method of JIS K7105 is preferably 9% or less.
