Welcome to the world of Thermochromic & Photochromic Pigments

Welcome to our blog by AMP Pigments. Today, we’re here to describe two innovative types: thermochromic and photochromic pigments. These Pigments are used in various industries with their unique properties.

Understanding Thermochromic Pigments:

Thermochromic pigments are special compounds that change colour in response to temperature.

Uses of Thermochromic Pigments:

  • Temperature: These pigments are used in labels and packaging to indicate temperature changes.
  • Safety indicators: Thermochromic materials are used in safety applications, such as temperature-sensitive stickers on electronics to detect overheating or in thermometers to indicate body temperature.
  • Thermal mapping: Thermochromic coatings are employed for thermal mapping to monitor temperature distribution across surfaces, facilitating quality control and process optimization.

Understanding Photochromic Pigments:

Photochromic pigments undergo reversible colour changes upon exposure to light, particularly ultraviolet (UV) radiation. This light-induced transformation is reversible, meaning the pigment returns to its original color when removed from light. The mechanism involves the photoisomerization of certain molecules within the pigment.

Uses of Photochromic Pigments:

  • Photochromic lenses: Perhaps the most well-known application of photochromic pigments is in eyeglass lenses that darken in response to sunlight, providing automatic protection against harmful UV rays.

  • Sun-sensitive materials: Photochromic coatings are used in various sun-sensitive materials, such as clothing, outdoor furniture, and architectural glass, offering sun-activated color-changing effects and UV protection.

  • Security printing: Photochromic inks are employed in security printing to create tamper-evident features, such as currency or identification documents that change colour when exposed to light, preventing counterfeiting.
