Zusammenfassung:	The present invention relates to lignin-containing compositions comprising: 0 to 50 percent by weight of lignin; 0 to 50 percent by weight of a liquid C2-C4polyol; and 10 to 50 percent by weight of an acrylic resin; wherein the percentages by weight are expressed relative to the total dry weight of the composition, and wherein the total dry weight of the composition amounts to 100 percent. The present invention further relates to processes for sealing joints or coating surfaces using such a composition. Moreover, the present invention relates to joints sealed and surfaces coated using such a composition, as well as vehicles comprising such sealed joints and coated surfaces. La présente invention concerne des compositions contenant de la lignine comprenant : de 0 à 50 % en poids de lignine ; de 0 à 50 % en poids d'un polyol en C2-C4 liquide ; et 10 à 50 pour cent en poids d'une résine acrylique ; les pourcentages pondéraux étant exprimés par rapport au poids sec total de la composition, et le poids sec total de la composition s'élevant à 100 pour cent. La présente invention concerne en outre des procédés pour joints d'étanchéité ou surfaces de revêtement employant une telle composition. De plus, la présente invention concerne des joints étanchéifiés et des surfaces revêtues à l'aide d'une telle composition, ainsi que des véhicules comprenant ces joints étanchéifiés et ces surfaces revêtues.
