Active amine/Amine synergist

Active amine is an acrylate photosensitization accelerator containing a tertiary amine structure, which can have a photosensitive synergistic effect with the hydrogen abstraction photoinitiator benzophenone, and can increase its photocuring rate in colored ink systems.

Under the condition of the same amount of pigment added, the amount of photoinitiator can be reduced, and vice versa, the ratio of pigment/filler in the formula can be increased, and the hiding power and tinting power of the ink can be improved.
