Abstract
The present invention relates to a process for manufacturing coated substrates by providing a substrate, providing at least one mineral material, providing a polysaccharide material comprising one or more polysaccharides, coating the substrate with the at least one mineral material, and coating the resulting pre-coat layer of mineral material with the gel comprising one or more polysaccharides, as well as the coated substrate obtained by this process and its use.
Claims46
A process for manufacturing a coated substrate comprising the steps of:
- a) providing a substrate;
- b) providing at least one mineral material comprising calcium carbonate;
- c) providing a polysaccharide material comprising one or more polysaccharides;
- d) coating the substrate with the at least one mineral material to obtain a pre-coat layer containing from 2 gm−2 to 50 gm−2 of mineral material;
- and
- e) coating the pre-coat layer of mineral material with the polysaccharide material comprising one or more polysaccharides to obtain a coated substrate.
The coated substrate according to 42, that is coated paper.
