Abstract
The present invention is directed to a method for coating a sheet-like cellulose containing material by applying a composition comprising at least one glucan (G), which has a β(beta)-1,3-glycosidically linked main chain and at least one side group having a β(beta)-1,6-glycosidic bond to the main chain, particularly Schizophyllan, and at least one solvent (S), particularly a ionic liquid, on the surface of the sheet-like material.

A method for coating a sheet-like cellulose containing material comprising applying a composition, comprising at least one glucan (G), which has a β(beta)-1,3-5 glycosidically linked main chain and at least one side group, having a β(beta)-1,6-glycosidic bond to the main chain, and at least one solvent (S), onto the surface of the sheet-like material.
A composition comprising:
- i) at least one glucan (G), which has β(beta)-1,3-glycosidically linked main chain and at least one side group having a (i(beta)-1,6-glycosidic bond to the main chain;
- ii) at least one ionic liquid;
- and
- iii) optionally at least one further additive (A).
A coated, sheet-like cellulose containing material comprising a coating layer, which comprises at least one glucan, which has a P(beta)-1,3-glycosidically linked main chain and at least one side group having a f3(beta)-1,6-glycosidic bond to the main chain.
