water reactive ink


Hydrochromic ink is a smart ink that changes colour in response to moisture. It is typically white when dry but becomes translucent when exposed to water. This colour change occurs because the ink contains pigment molecules that react to changes in the water content of the surrounding environment.

In the case of hydrochromic ink, the pigment molecules are hydrophilic or "water-loving." When the ink is exposed to moisture, these pigment molecules absorb the water molecules and swell in size, causing the ink to become more translucent or transparent. This reaction has been designed to be reversible, meaning the ink will return to its original colour once it dries out.

If you require irreversible inks or inks for flexographic or offset printing, we are happy to create a custom order for you in our lab.

Hydrochromic Ink is a versatile substance that can be used in various fields. In the world of art, it can be incorporated into paintings and installations to create dynamic and interactive effects as the artwork interacts with water or other liquids. When it comes to design, hydrochromic ink can be used to create unique and eye-catching patterns on fabrics and products. In education, it can be used to create engaging experiments that teach students about the properties of liquids and how they affect the ink.

Hydrochromic ink can also be used in engineering to develop sensors that can detect the presence of fluids. Finally, in fashion, it can be used to create garments which transform entirely when exposed to water, providing a new level of creativity in clothing design. Additionally, it can be used in the packaging industry to create packaging materials that indicate when a product has been exposed to water or moisture, making it easier to identify damaged items.
