Abstract
The present invention relates to a new coating method of a material intended for inkjet printing enabling high coating speeds while reducing or eliminating coating faults. The coating method of a material intended for forming images by inkjet printing comprises heating a composition intended to form the ink-receiving layer, the composition comprising at least one polysaccharide, polyvinyl alcohol, guar gum and inorganic particles having neutral or positive surface charge; treating a support by corona discharge; coating the composition directly on the treated support, using a coating machine in which the support runs; cooling the resulting coated, treated support to obtain the thermoreversible gelation of the composition; and drying the coated, treated support.

A coating method of a material intended for forming images by inkjet printing comprising:
- a) heating a composition intended to form the ink-receiving layer, said composition comprising at least one polysaccharide, polyvinyl alcohol, guar gum and inorganic particles having neutral or positive surface charge;
- b) treating a support by corona discharge;
- c) coating said composition directly on said treated support, using a coating machine in which the support runs;
- d) cooling the resulting coated, treated support to obtain the thermoreversible gelation of said composition;
- and
- e) drying said coated, treated support.
A coating method of a material intended for forming images by inkjet printing comprising:
- a) heating a composition intended to form an ink-receiving layer, said composition comprising at least one carrageenan, polyvinyl alcohol, guar gum and inorganic particles having neutral or positive surface charge;
- b) treating a support by corona discharge;
- c) coating said composition directly on said treated support, using a coating machine in which the support runs;
- d) cooling the resulting material to obtain the thermoreversible gelation of the composition;
- and
- e) drying the material.
