Zusammenfassung:	A method of transforming a polysaccharide into a cross-linkable polysaccharide is described which comprises providing a solution comprising a solubilized polysaccharide, converting the polysaccharide into an amino-polysaccharide by replacing at least one reactive group of the polysaccharide with an amine group, thereby creating the amino- polysaccharide; and crosslinking the amino-polysaccharide with methacrylate, thereby creating a cross-linkable polysaccharide. Also described is a method of transforming a cross-linkable polysaccharide into a light cross-linkable polysaccharide. Additionally, there is described a method of transforming a light cross-linkable polysaccharide into resin. Additionally, a method of transforming a polysaccharide into a cross-linkable polysaccharide via an intermediary molecule is provided. Lastly, a method of preparing a protective coating using the cross-linkable polysaccharide is provided. L'invention concerne un procédé de transformation d'un polysaccharide en un polysaccharide réticulable, qui comprend la fourniture d'une solution comprenant un polysaccharide solubilisé, la conversion du polysaccharide en un amino-polysaccharide par remplacement d'au moins un groupe réactif du polysaccharide par un groupe amine, ce qui permet de créer l'amino-polysaccharide ; et la réticulation de l'amino-polysaccharide avec du méthacrylate, créant ainsi un polysaccharide réticulable. L'invention concerne également un procédé de transformation d'un polysaccharide réticulable en un polysaccharide réticulable à la lumière. De plus, l'invention concerne un procédé de transformation d'un polysaccharide réticulable à la lumière en résine. En outre, l'invention concerne un procédé de transformation d'un polysaccharide en un polysaccharide réticulable par l'intermédiaire d'une molécule intermédiaire. Enfin, l'invention concerne un procédé de préparation d'un revêtement protecteur à l'aide du polysaccharide réticulable.
