Water-based Irreversible Temperature Rise Color Changing Ink

1.Color Change Introduction：Water-based irreversible temperature-changing ink is a kind of heat-sensitive color-changing ink or thermochromic ink, which changes color due to temperature changes. This color change is completely irreversible. It is divided into two types: water-based irreversible temperature-increasing color-developing ink and water-based irreversible temperature-increasing color-changing ink.。Water-based irreversible temperature-increasing color-developing ink is colorless below a certain temperature. When the temperature rises above this specific temperature, the color begins to gradually appear, and then is completely irreversible; water-based irreversible temperature-increasing color-changing ink is a kind of water-based irreversible temperature-increasing color-changing ink below a certain temperature. Color, when the temperature rises above this certain temperature, the color begins to gradually change to another color, and then becomes completely irreversible.

2.Printable substrate：Water-based irreversible temperature-changing color-changing 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.

 4.printing method：Mainly used for screen printing, gravure printing and flexographic printing.

 5.Drying method：All are water-based, volatile and dry.

 6.Color variety：The temperature ranges from 70℃ to 130℃, and the colors are diverse and rich. For example, irreversible heating will show yellow, and irreversible heating will turn green to-
