Abstract
(EN)
A multi-layer coated copy paper has an intermediate basecoat layer between the base paper layer and outer topcoat layer containing from 10% to 70% ground calcium carbonate (CaCO3), from 90% to 30% fully or partially calcined clay (Si4Al4O10(OH)n' where n$m(f)8), and from 0% to 30% satin white (3CaO-Al2O3-3CaSO4-31H2O), with a binder.
