Embodiment 1

[0035] structured as figure 1 A material with temperature-sensitivity change and optical angle-dependent color difference is shown, including temperature-changing material and optical angle-dependent color-dependent material, forming a layered structure, and the basic structure is a temperature-changing material layer and an optical angle-dependent color-dependent material layer Alternately. The preparation method is as follows:

[0036] 1) Deposit, coat, ink, spray, coat, and fill a layer of temperature-changing material on one side of the material;

[0037] 2) Then deposit, coat, ink, spray, coat, and fill a layer of color-dependent material on the same side or the other side to obtain a material with temperature-sensitive change and optical color-dependent color.

Embodiment 2

[0039] structured as figure 2 The shown material with temperature-sensing change and optical angle-dependent color change includes temperature-changing material and optical angle-dependent color-dependent material to form a mixed structure. The preparation method is as follows: the temperature-changing material and optical angle-dependent color-dependent material are combined The color materials are mixed evenly, and a mixed structure is formed through adsorption, coating, ink making, spraying, coating, filling, etc., to obtain materials with temperature-sensitive changes and optical angle-dependent changes.

Embodiment 3

[0041] structured as image 3 A material with temperature-sensing change and optical angle-dependent color difference is shown. The temperature-changing material is used as the film structure of the optical functional layer in the film structure, and has a typical optically variable material structure-core structure: respectively, temperature In addition to the core structure, the variable material layer / medium layer / temperature-changing material layer or reflective layer / medium layer / temperature-changing material layer can also be modified with several other layers as a protective or optical function layer.

Abstract

The invention discloses a material with temperature-sensing-changing and optically-angle-variable color. The material comprises: a layered structure comprising a temperature-varying material and an optically-angle-variable material; or a mixed structure formed by the temperature-varying material and the optically-angle-variable material; or a film system structure, in which the temperature changematerial serves as an optical function layer. The color effect of the material varies with temperature and angle, including but not limited to brightness, hue, and angle-depended color variation. Theproduct widens the color gamut of the optically variable pigment, enriches the color display effect of the optically variable pigment, and has multiple anti-counterfeiting and novel characteristics.

Description

Technical field: [0001] The invention relates to the technical field of optical anti-counterfeiting, in particular to a material with temperature-sensitive change and optical angle-dependent color difference and a preparation method thereof. Background technique: [0002] Thermochromic materials refer to materials with thermochromic properties. Thermochromism, that is, certain substances can undergo color changes due to structural changes at specific ambient temperatures, also known as "thermochromism" or "thermochromism". There are many uses of heat-sensitive color-changing materials. At present, its scope of use is mainly in printing, paint, toys, anti-counterfeiting, textile and clothing, and daily necessities. [0003] Generally, there are three types of heat-sensitive color-changing materials: microcapsule type, heavy metal double salt complex type and liquid crystal type. The former is prepared by an electron transfer type organic or inorganic compound system. Electr...
