What are the characteristics of temperature change ink

Temperature change ink known as thermochromic ink , showing temperature sensitive ink or ink . Temperature change ink into three categories: the display a specific color temperature , the color disappears upon heating becomes colorless glow in the dark immediately restore the original color , because reversible change process , referred to as " inversion variable message color ink " ; Show colorless at room temperature, after heating into another color , then restore the original cooling colorless , photoluminescent films the change process reversible , referred to as" inversion hair color ink " ; ink display color at room temperature , after heating into another color , because the reversible change process referred to as " inversion variable color ink transfer ". 

The organic photochromic material

Our organic photochromic materials began in the 1980s . Nankai University graduation certificate security seal , is the oldest university diploma gravels for driveway application security is the first application of this technology in the security identification technology. Then the technology have been used in garment decoration , inks , paints, plastics , and other fields , to produce color clothing, color sandals, color plastic , color glasses , etc. ; covert military camouflage material also successfully Photoluminescent pigment, such as gradient color chameleon camouflage applications have mature, discolored material, especially by consumers in the clothing industry .
