Water Fastness of Screen Printed Pearl Luster Pigments based on Synthetic and Natural Mica on Polyvinyl Chloride Foil and Rich Mineral Paper

Abstract

The present study attempts to examine water fastness of screen printed pearl luster
pigments based on synthetic and natural mica on polyvinyl chloride foil and Rich
Mineral Paper. Three types of pearl luster pigments were used, each different from
the other in composition, interference colour and particle size: one pigment based
on synthetic mica (Pigment 1) and two pigments based on natural mica (Pigment
2 and Pigment 3). Pearl luster pigments were applied to the printing base (PVC
transparent base) in 15wt.% concentration and printed by means of screen printing
technique. The test of water fastness was made on prints, where the samples
were soaked in distilled water for 6 and 12 days. It was established that this water
treatment did not have any significant impact on the durability of screen printed
pearl luster pigments. The pigments could demonstrate slightly better water fastness
after being printed on Rich Mineral Paper.
