Beschreibung
Zusammenfassung:	A composite paper comprising: a paper substrate having a top surface and a bottom surface; and a coating layer on at least a portion of the top surface of the paper substrate; wherein the coating layer is formed from a composition comprising: a cellulose ester resin, and at least one organic solvent; wherein a difference between the refractive index of the paper substrate and the refractive index of the at least one cellulose ester resin is less than 0.035 L'invention concerne un papier composite comprenant : un substrat de papier ayant une surface supérieure et une surface inférieure ; et une couche de revêtement sur au moins une partie de la surface supérieure du substrat de papier ; la couche de revêtement étant formée à partir d'une composition comprenant : une résine d'ester de cellulose, et au moins un solvant organique ; une différence entre l'indice de réfraction du substrat de papier et l'indice de réfraction de la ou des résines d'ester de cellulose étant inférieure à 0,035.
