Black to Deep Blue – Activated by High-Temperature Boiling

Our company has received positive feedback from a customer who recently adopted our high-temperature boiling activated thermochromic ink. The ink appears solid black at room temperature, but after being subjected to a boiling process, it reliably turns into a vivid deep blue with excellent uniformity and colorfastness.

The customer expressed strong satisfaction with the product, particularly highlighting its stable color transition and consistent performance under high-temperature, high-humidity conditions.
