Abstract
Previously, we have shown that coatings formulated
with fumed silica pigments are capable of producing glossy
inkjet media, despite the presence of these coating cracks,
caused by shrinkage of the coating layer. However, their
high cost and the inability to run them at high solids (>30%
solids) limits their commercial application. Raising the
coating solids with the addition of conventional pigments
reduces the amount of shrinkage that occurs during drying,
and thereby reduces the coating cracks, improving the final
gloss of the coating layer.
In this research, the solids of fumed silica coating
systems were increased by adding co-pigments of different
