Abstract
The invention concerns a method for modification of the surface of a body, especially a film-shaped body, wherein a fiber-containing substance comprising nano-sized polysaccharide fiber particles is dispersed in a medium essentially composed of water and a polar solvent to form a suspension. The suspension is applied on the surface by a printing method. According to the invention, the viscosity of the suspension is adjusted to a range that is suitable for the printing method by adjusting the fiber concentration of the suspension. The invention concerns also a composition disposable onto the surface of a body, such as a film-shaped body, by a non-contact inkjet printing method. According to the invention, the composition comprises nanocellulose fibers suspended in a medium essentially composed of water and a polar solvent, miscible with water, wherein the concentration of nanocellulose fibers is 0.5 to 1.5%, preferably 0.5 to 1%, most preferably about 0.7% of said composition.
