Abstract
Description
Technical Field
[0001] The invention relates to the field of inks, in particular to a pearlescent ink and a production process thereof. Background Art
[0002] Pearlescent ink is an ink with pearlescent color effect. The pearlescent pigment used is flat particles with a particle size of 5-25μm and a thickness of 0.2-0.5μm. The particle size of the pigment used in general four-color ink is 0.02-0.08μm, and the particle size of other bright colors is 0.2-0.7μm. It can reproduce the luster and color of pearls, shells, butterflies, fish and metals in nature. It is low-priced and has excellent durability. It can also prevent scanners, extension machines and color copiers from copying. There are two main formulas for existing pearlescent inks. The first formula is 70-80% screen varnish and 20-30% pearlescent glitter. Pearlescent glitter is easy to accumulate and transfer poorly.
