DPS (Diphenyl Sulfone) Sensitizer

Sensitizer for thermal paper formulations.
Enhances developer reactivity, image density and print stability in thermal recording systems.

High-Performance Sensitizer for Thermal Paper Applications

DPS (Diphenyl Sulfone) functions as a sensitizer in thermal paper coating formulations. By improving the reactivity between developers and colour formers, DPS enhances image density, sharpness and response speed in thermal imaging systems. It contributes to reliable print performance under a variety of operating and storage conditions.

As a non-developer auxiliary, DPS plays an essential role in balancing activation temperature, print sensitivity and background stability in both top-coated and non-top-coated thermal papers.

NAGASE supplies DPS worldwide with technical support, regulatory documentation and logistics expertise for thermal paper manufacturers.

Applications

DPS is applied as a sensitizer to optimize performance in thermal paper systems.
