How is the ink resin adhesion color fastness
- 2024-03-07 17:36:33
- admin
Ink resin is the pigment carrier in the ink, is the core material of the ink, its quality is good or bad, will directly affect the performance of the ink, because the connection material to a large extent determines the viscosity of the ink, viscosity, dryness, fluidity and other properties. Color fastness The adhesion between the ink and the substrate mainly includes the chemical bond force ...

Ink resin coloring power
- 2024-03-08 17:34:54
- admin
Organic pigment is the most basic material to provide color to the ink, but as the ink attached to the surface of the substrate, the color shown to the consumer often produces more or less deviations from the color of the pigment itself. The reason is that in the ink, the pigment particles do not exist alone, but are dispersed in the connecting material medium. Microcosmic, the best wetting disper...
