Reversible temperature rise color changing ink

1.Color Change Introduction：Reversible temperature rise color changing ink is a type of thermosensitive color changing ink or thermosensitive color changing ink that undergoes color changes due to temperature changes, and this color change is reversible. It is divided into three types: temperature rise color developing ink, temperature rise color fading ink, and temperature rise color conversion ink.The temperature-increasing color-developing ink has no color at 40°C or below. When the temperature rises above 40°C, the color begins to gradually appear; the temperature-increasing color-developing ink has color below 40°C. When the temperature rises above 40°C, The color begins to gradually disappear; the temperature-changing color ink is one color below 40°C, and when the temperature rises above 40°C, the color begins to gradually change to another color.

2.Printable substrate：Thermochromic ink can be printed on substrates such as paper, plastic, film, metal, glass and ceramics。

3.Application areas：Used in tobacco and alcohol, medicines, food, cosmetics, electronic products, glass products, textiles, children's toys, securities bills, etc.
