There are 2 primary warmth-delicate factors from the heating-delicate substance covering: one is a leuco dye or leuco coloring the other is really a color designer.clear imaging。 This type of thermosensitive materials can also be termed as a two-part compound variety thermosensitive taking material.
The thermal movie comprises a polyester (Family pet) motion picture basic, a thermal coating, and a protecting covering. The creation of the thermal movie is a special covering approach. A level of energy chromogenic coating as well as the defensive level, the chromogenic level is a mix of adhesive, creator, and leuco coloring (or leuco dye), and is not divided by microcapsules, along with the chemical response is within a "latent" status. If the warmth-making print out brain details the thermal coating, the designer along with the leuco coloring where the printing head printing chemically react and alter coloration to produce graphics and text message. When the thermal fabric is positioned above 70 ℃, the band lens , The warmth-vulnerable layer actually starts to modify color. The factors of its discoloration should be reviewed looking at the structure.
