Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a safety product marked with product safety information. The safety product is printed by using a combination of a strong optically variable optical film pigment and a weak optically variable optical film pigment. The two use the same material And the manufacturing process, solve the current problem of mismatching physical and chemical properties, making the printed security products more tightly combined with different marks

Embodiment 1

[0061] Such as figure 1 As shown, the present invention provides a schematic plan view of a security product with a first mark and a second mark made by pairing [bronze / light green] strong light-changing ink and [bronze / dark green] weak light-change ink.

[0062] figure 1 Among them, the first mark and the second mark respectively contain [bronze / light green] optically variable optical film pigment and [bronze / dark green] optically variable optical film pigment. The first mark serves as the background and the second mark serves as the lion pattern. When observed at the first viewing angle, both of them show a bronze color, which can be regarded as printing with the same ink (such as figure 1 Middle and upper picture); when observed at the second viewing angle, the first mark is light green, and the second mark is dark green, which shows that there is a clear difference between the two (such as figure 1 bottom middle picture).

[0063] In Example 1, the thin pigment str...

Embodiment 2

[0074] This embodiment relates to a security product with a first mark and a second mark made by using blue / purple weak optically variable ink and blue / purple strong optically variable optical film pigment ink in pair. The first mark and the second mark respectively contain [blue / purple] optically variable optical film pigment and [blue / purple] optically variable optical film pigment. If the first mark is used as the background, the second mark is used as the characteristic pattern. When observed at the first viewing angle, both of them show blue, which can be regarded as printing with the same ink; when viewed at the second viewing angle, the first mark is purple, and the second mark is purple. Specific patterns can refer to figure 1 .

[0075] In Example 2, the thin pigment structure of the weak optical variable optical film used in the first mark is as follows:

Abstract

The invention provides a safety product marking product safety information. A printing face of the safety product is printed with marks comprising identification information. The marks include a first mark printed through weak light changing ink and a second mark printed through hard light changing ink, and the marks are observed under visible light, at the first observation angle, the first mark and the second mark display the similar or same color effect, and after the first observation angle is changed into the second observation angle, the color of the first mark changes slowly, the color of the second mark changes obviously, and the color change of the first mark and the color change of the second mark form bright contrast. The two kinds of light changing optical thin film pigments of the provided safety product adopt the homogeneous materials and the same preparation process and have the similar physicochemical properties, the binding character of the pigments is good, the metal flickering feelings on the appearance effect of the pigments are consistent in matching, the two pigments have the similar color expressiveness and the metal flickering feeling on the visual effect, and better homochromatic matching can be achieved better.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a security product marked with product safety information, in particular to a security product marked with product safety information by combining strong optically variable optical film pigments with weak optically variable optical film pigments. Background technique [0002] Optical variable optical film pigment (OVP) is a kind of pigment that shows that the color will change with different viewing angles. The use effect is manifested in the marking (such as text, pattern, packaging, etc.) printed or coated with ink formulated with this pigment. etc.) will also show different colors with different viewing angles, that is, a visual effect of "changing color with the angle". Observers can easily identify the features of the item through the color change of the printed mark. Because the characteristic of "angle-dependent color change" unique to optical variable optica...
