Description

Thermochromic article

This creation is about a temperature-sensitive color-changing article, in particular, a structure that can simplify the printing process, make the printing process easier, and reduce the amount of thermochromic ink used to reduce the cost of the temperature-sensitive color-changing article.

In order to increase the interest or functionality of goods, to attract consumers' purchases, there are a variety of products on the market (such as: cups, clothes, shoes, storage boxes/bags, ...) that will be printed on the surface with a thermochromic ink. The thermochromic pattern, the thermochromic pattern will change color due to temperature changes.

As shown in the first and second embodiments, the conventional thermochromic article includes an article body 10, and the surface of the article body 10 is provided with a bottom layer 20 patterned by a graphic design. The color layer 20 is overprinted to cover a thermochromic layer 30; wherein: the article body 10 (as shown in Figures 1 and 2) has a surface on which the base layer 20 and the thermochromic layer 30 are printed. In the embodiment shown in Figures 1 and 2, the article body 10 is illustrated by a mug; however, the article body 10 is not limited to a mug, but also a garment, a shoe, a storage box (bag) or Other goods.

The undercoat layer 20 (shown in Figures 1 and 2) is an ink prepared by a non-temperature sensitive coloring material and is provided on the surface of the article body 10 by printing.

The thermochromic layer 30 (as shown in Figures 1 and 2) is a thermochromic material The prepared ink is overprinted on the undercoat layer 20 after the undercoat layer 20 has dried up, and after the thermochromic layer 30 is dried, a product having a thermochromic pattern on the surface is obtained.

Before the color-changing layer 30 is not discolored, the color of the pattern printed on the surface of the article body 10 is the color of the ink of the thermochromic layer 30, and when the thermochromic layer 30 is heated and discolored, it will be converted into a colorless transparent shape. It is revealed that the ink of the undercoat layer 20 has both a color and a color change effect.

For example, the color of the ink of the bottom color layer 20 is red, the color of the color change ink of the thermochromic layer 30 is blue, the color temperature of the thermochromic layer 30 is 35 ° C, and the temperature of the thermochromic layer 30 is not changed. Before, the graphic visual color printed on the surface of the article body 10 is blue. When the temperature changes to 35 ° C set by the thermochromic layer 30, the thermochromic layer 30 will change from blue to colorless and transparent. The red color of the underlying layer 20, in turn, achieves a color changing effect.

With the above configuration, the conventional thermochromic article can improve the taste or functionality of the article; however, since the base layer 20 and the thermochromic layer 30 must be successively printed on the surface of the article body 10, and must wait during the printing process. After the underlying layer 20 is dried, the thermochromic layer 30 can be overlaid on the underlying layer 20, so the printing process is quite time consuming; at the same time, the underlying layer 20 and the thermochromic layer 30 must be separately plated, and the plate is to be added. Cost, especially in the overprinting process, the printing area must be accurately aligned, which will increase the difficulty of the printing process; further, before the thermochromic layer 30 is not temperature-sensitive, to ensure that the thermochromic layer 30 can cover the hidden bottom The color layer 20 prevents the under color layer 20 from interfering with the color of the thermochromic layer 30, and the thermochromic layer 30 is usually formulated at a higher addition ratio, and even needs to be repeatedly printed twice to completely cover the underlying layer 20, and is increased. The amount of thermochromic ink used.

The purpose of this creation is to improve the lack of the above-mentioned conventional thermochromic articles, to provide a process that can simplify the printing process, make the printing process easier, and reduce the temperature change. The amount of color ink used to reduce the cost of the thermochromic article construction.

In order to achieve the above object, the temperature-sensitive color-changing article of the present invention comprises an object body, and the surface of the object body is provided with a thermo-sensitive color-changing layer patterned by a graphic design; wherein the thermochromic layer is non-temperature-sensitive The ink obtained by blending the color-changing raw material and the thermochromic raw material is further disposed on the surface of the article body by printing, or the thermochromic layer is blended by two thermosensitive materials of different colors and different color-changing temperatures. The ink is then printed on the surface of the article body.

With the above configuration, it is possible to provide a thermochromic article which can simplify the printing process, make the printing process easier, and reduce the amount of thermochromic ink used to reduce the cost.

In order to understand more clearly the technical means and structure of the creation to achieve the purpose, please follow the feasible examples shown in Figures 3 and 4, as detailed below: as shown in Figures 3 and 4, The article is provided with a temperature-sensitive color-changing article, and includes an article body 40. The surface of the article body 40 is printed with a thermographic color-changing layer 50 patterned by an artist design; wherein: the article body 40 (as shown in Figures 3 and 4) , the surface of which can provide a thermochromic layer 50 printing. In the embodiment shown in Figures 3 and 4, the article body 40 is illustrated by a mug; however, the article body 40 is not limited to a mug, but also a garment, a shoe, a storage box (bag) or Other goods.

The thermochromic layer 50 (shown in Figures 3 and 4) is an ink obtained by blending a non-temperature sensitive coloring material and a thermochromic material, and is further provided on the surface of the article body 40 by printing. The raw materials and thermochromic pigments are of different colors.

Before the color-changing layer 50 is not discolored, its color is the color of the non-temperature-sensitive color-changing material and the thermo-chromic material of two different colors, and the color-changing material is discolored to colorless and transparent. In the case of the shape, the thermochromic layer 50 will only exhibit the color of the non-temperature-sensitive color-changing material, thereby achieving a color-changing effect.

For example, suppose that the non-temperature-sensitive color-changing raw material is red, the thermo-sensitive color-changing raw material is blue, and the color-changing temperature of the thermo-sensitive color-changing raw material is set to 35 ° C, and the red non-temperature-sensitive color-changing raw material is blended with the blue thermo-sensitive color-changing raw material. The ink is purple, so the thermochromic layer 50 printed on the surface of the article body 40 is purple. When the temperature is changed to 35 ° C set by the thermochromic material, the thermochromic material will be converted into a colorless and transparent shape. The thermochromic layer 50 will only exhibit red color of the non-temperature sensitive coloring material, thereby achieving a color changing effect.

The thermochromic layer 50 is another possible embodiment. The ink is made up of two thermochromic materials of different colors and different color-changing temperatures, and is disposed on the surface of the article body 40 by printing.

Before the color-changing layer 50 is not discolored, its color is the color of the thermochromic materials of two different colors, and when one of the thermochromic materials changes color to a colorless and transparent shape, the feeling The thermochromic layer 50 will only exhibit the color of another thermochromic material. Moreover, when the other thermochromic material changes color to a colorless and transparent shape, the other thermochromic layer 50 will disappear as if it is invisible, thereby achieving a color changing effect.

For example, suppose that one thermochromic material is red, the color temperature of the red thermochromic material is set to 70 ° C, and the other thermochromic material is blue, and the color temperature of the blue thermochromic material is set to At 35 ° C, since the ink of the red thermochromic material and the blue thermochromic material is purple, the thermochromic layer 50 printed on the surface of the article body 40 is purple, and the temperature changes to the blue thermochromic material. At 35 °C, the blue thermochromic material will be converted into a colorless transparent shape. At this time, the thermochromic layer 50 will only show the red color of another thermochromic material, and when the temperature changes to the red thermochromic material. At the set temperature of 70 ° C, the red thermochromic material will be converted into a colorless transparent shape, and at this time, the thermochromic layer 50 will disappear as invisible, thereby achieving a color changing effect.

The above thermochromic materials are all reversible. In other words, as long as the temperature is lowered below the color change temperature set by the thermochromic material, the color can be restored to the existing color.

Further, the present invention can print the thermochromic layer 50 on the surface of the article body 40 by screen printing or pad printing.

As can be seen from the above description and the embodiment shown in the drawings, since the present invention directly prints the thermochromic layer 50 on the surface of the article body 40, the conventional method must be omitted to print the undertone layer 20, and then the thermochromic layer 30 is overprinted. The process can simplify the printing process, save the plate making cost, make the printing process easier, and reduce the production cost, and the color of the base layer 20 without the conventional method can interfere with the color temperature of the thermochromic layer 30, thereby saving the temperature. Change the amount of ink used, and reduce the cost of raw materials. Therefore, this creation does have significant progress, and its construction is indeed unprecedented. Cheng has already complied with the new patent requirements, filed a patent application according to law, and prayed for a patent. To the sense of virtue.
