As shown in FIGS. 1A and 1B, the structure of the iris color mosaic pattern printed material in the first embodiment of the present invention is as follows: a transparent resin layer 4, an iris color full solid ink layer 2 and an iris color partial solid ink. An iris color solid ink layer consisting of layer 3,
The continuous fine pattern layer 1 having a light absorbing color tone such as black is laminated. In this embodiment, the solid ink layer 3 of the iris color portion has a polka dot pattern, but the pattern of the solid ink layer 3 of the iris color portion is arbitrary, and a pattern suitable for the mosaic pattern to be reproduced may be used. When the printed matter having the above structure is viewed through the transparent resin layer 4, as shown in FIG. 1B, a continuous fine pattern layer 1 and a laminated portion A of one iris color solid ink layer, and the continuous fine pattern layers 1 and 2 are formed. The layered portion B with the iris-colored solid ink layer has a color tone in which the continuous fine pattern layer 1 is colored with one iris-colored solid ink layer or a color tone composed of two iris-colored solid ink layers. Since it is visible, the continuous fine pattern layer 1 becomes an iris color mosaic pattern printed matter which is colored by being colored by the iris color solid ink layer.

The structure of the second embodiment of the present invention is, as shown in FIG. 2, a transparent resin layer 4 and an iris color solid ink layer.
3a and an iris color solid ink layer 3b, which are two layers, and a continuous fine pattern layer 1 having a light-absorbing color tone such as black. The shapes of the two color iris color solid ink layers 3a and 3b are arbitrary, and the iris color partial solid ink layers 3a and 3b are partially overprinted. It is preferable to provide the entire surface of the continuous fine pattern layer 1 with at least one solid iris color ink layer, but it is also possible to provide an iris solid ink layer where the continuous fine pattern layer 1 is partially exposed. In the above-mentioned configuration, the color tone of the iris color solid ink layer is three types of the iris color part solid ink layer 3a single color, the iris color part solid ink layer 3b single color, and the laminated color tone of the iris color part solid ink layer 3a and the iris color part solid ink layer 3b. The continuous fine pattern layer 1 is colored in the color tone. Therefore, it is possible to reproduce multicolor tones by using solid iris color inks with a small number of colors. In this embodiment, the two iris color partial solid ink layers 3a and 3b are used, but the number of colors used may be three or more and is arbitrary.

As shown in FIG. 3, the structure of the third embodiment of the present invention is such that a continuous fine pattern layer 1 having a light absorbing color tone is formed on the surface of a base material layer 5 made of paper or the like, and an iris color solid ink layer. 2 and an iris color solid ink layer consisting of the iris color partial solid ink layer 3 are formed by printing, and a transparent resin layer 4 is formed thereon.
Is formed by coating or printing. Also in the above configuration, the iris color solid ink layer 2 and the iris color partial solid ink layer 3 do not form an iris color solid ink layer, but the two iris color partial solid ink layers 3a and 3b are used as in Example 2. Then, it may be provided so as to cover the entire surface of the continuous fine pattern layer 1 having a light absorbing color tone so that there is no gap.

As shown in FIG. 4, the construction of the fourth embodiment of the present invention is an iris-colored solid ink layer comprising an iris-colored whole solid ink layer 2 and an iris-colored partial solid ink layer 3 on a transparent resin layer 4 composed of a transparent plastic film. And a continuous fine pattern layer 1 having a light-absorbing color tone, an adhesive layer 7, and a base material layer 5 made of paper or a heat-adhesive resin in this order. Also in the above configuration, the iris color solid ink layer 2 and the iris color partial solid ink layer 3 do not constitute an iris color solid ink layer, but the entire fine pattern layer 1 is formed by using the iris color solid ink layer 3 of a plurality of colors. You may form an iris solid ink layer so that it may cover.

The solid iris ink layer used in the present invention comprises
Iris-colored pearl pigment particles in which the surface of natural mica is coated with high-refractive-index metal oxides such as titanium oxide and iron oxide
It is formed by an iris color ink including 11 by a gravure printing method or the like. As shown in FIG. 5, the coloring principle of the iris-colored pearl pigment causes the light reflected at the boundary between the layer of titanium oxide having a high refractive index, the mica having a low refractive index and the surrounding medium to give an iris-colored pearl luster. By changing the film thickness of the titanium oxide coating the mica and changing the thickness d of the iris color pearl pigment particles, a specific iris color can be emphasized. Depending on the thickness of the titanium oxide layer, part of the incident light 8 (for example, the green component) is reflected, while its complementary color (red in this case) is transmitted, and from the reflected color and the transmitted light 10, which are reflected light 9 respectively. When the background has a reflective color tone such as white, the complementary color that is a transmission component is reflected back to the original by the background, and the color effect is reduced by adding to the component that is the original reflection color. Therefore, it is necessary to form the continuous fine pattern layer 1 as the background color with a light absorbing color close to black.

Due to the thickness of the high-refractive-index metal oxide such as titanium oxide coating the particles of mica, one of the wavelengths of visible light interferes to develop an iris color. The color developed varies depending on the thickness d of the iris-colored pearl pigment particles made of mica coated with titanium oxide. For example, when the thickness d of the iris color pearl pigment particles is 40 to 60 mμ, it is silver, 60 to 80
Yellow for mμ, red for 80-100 mμ, 1
An iris color of blue is produced in the case of 00 to 140 mμ and a green iris color is produced in the case of 120 to 160 mμ. By setting the thickness of the iris color pearl pigment particles as described above, silver or pearl color, yellow or gold color, red, blue and green iris color inks can be obtained.

The composition of the iris color ink for forming the iris color solid ink layer is 10 to 10 in the ink vehicle.
The above-mentioned pearlescent pigments such as pearlescent, yellow, red, blue and green are added in an amount of 20% by weight.
The particle size of the iris color pearl pigment particles 11 is preferably in the range of 5 to 25 .mu. By doing so, when printing with a gravure printing machine, the stability of the ink on the printing machine is improved and fluctuations in the printing color can be prevented. The color tone of the iris color ink used for forming the iris color solid ink layer is pearl color, yellow, red, blue, green and the like, and these color tones are used in combination.

The pattern shape of the continuous fine pattern layer 1 is arbitrary as long as it is a fine pattern composed of a continuous pattern, but in order to emphasize the iris color pearl effect, a combination of parallel or parallel straight line groups and curved line groups is used. An irregular shape with no directionality is suitable. The line interval or line thickness may be arbitrarily set within the printable range according to the purpose, but is 10 to 50.
0 micron is suitable. Since the continuous fine pattern layer 1 needs to absorb light, it is printed with black or a dark color ink close to black. By printing the continuous fine pattern layer 1 using a dark color ink, only the light of a specific wavelength is reflected by the iris color solid ink layer provided on the continuous fine pattern layer 1, and at the same time, the iris solid ink layer is formed. Since the transmitted light is not absorbed and reflected by the continuous fine pattern layer 1, the iris color pearl effect is emphasized.

As the transparent resin layer 4, it is preferable to use a resin having excellent transparency and abrasion resistance on the surface. When a plastic film is used, a biaxially stretched polyethylene terephthalate film or a biaxially stretched polypropylene film is used. A film with excellent transparency, rigidity, strength, and dimensional stability, such as polyvinyl chloride resin, acrylic resin, urethane resin, polyamide resin, etc., is suitable for forming by coating, printing, etc. it can.

The base material layer 5 is an opaque base material composed of thin paper, paper such as paperboard, synthetic paper, colored plastic, aluminum foil, or a laminate thereof, or polyethylene, polypropylene, ethylene-vinyl acetate copolymer. A heat-adhesive resin such as the above can be used. When the former base material is used as the base material layer 5, it is suitable for applications such as boxes and labels, and when the latter base material is used, it is suitable for packaging bags and the like. As the adhesive layer 7, a urethane-based adhesive is used when the base material layer 5 is a non-absorbent base material such as synthetic paper, plastic, aluminum foil, and the base material layer 5 is made of paper. In the case of a flexible substrate, an adhesive such as emulsion type can be used.

The method for producing an iris-colored mosaic pattern print according to the present invention uses a transparent resin layer 4 made of a plastic film such as a biaxially stretched polyethylene terephthalate film, and one side thereof is subjected to gravure printing, silk screen printing or the like to produce an iris-colored solid ink. Layer and continuous fine pattern layer 1 or, if necessary, further laminating a base material layer 5 such as paper, aluminum foil, plastic sheet or the like on the surface of the continuous fine pattern layer 1 with an adhesive layer 7 interposed therebetween. In the same manner as above, the continuous fine pattern layer 1 and the solid iris ink layer are provided on the surface of the base material layer 5 made of paper or the like, and the surface of the solid iris ink layer is transparent by roll coating, gravure printing, silk screen printing, etc. It is manufactured by a method of forming the resin layer 4 and smoothing the surface.

The iris-colored mosaic pattern print of the present invention is suitable for high-quality printing, tamper-proof printing, and precision printing. As a specific usage form, it can be used as a packaging bag, a packaging paper box, a display label, a display board, a plastic card, etc., on which the iris color mosaic pattern printing is entirely or partially provided.
