Zusammenfassung:	A solvent-free transfer process for providing a uniformly colored interlayer sheeting having a roughened or embossed surface wherein a composite coating consisting of a layer containing finely divided solid crystalline pigment particles (12) dispersed in a resin binder and at least one non-pigmented layer (14) is transferred from a carrier film (10) to the sheeting is disclosed. Transfer of the coating is accomplished while maintaining the pigment particles in the solid crystalline phase and maintaining the roughened surface of the sheeting. Procédé de transfert sans solvant servant à produire une feuille intermédiaire de couleur uniforme présentant une surface rugueuse ou gaufrée. Le procédé permet de transférer sur la feuille, à partir d'un film de support (10), un revêtement composite comprenant une couche contenant des particules de pigment cristallin solide finement divisées (12) dispersées dans un liant à base de résine et au moins une couche non pigmentée (14). On effectue le transfert du revêtement tout en maintenant les particules de pigment dans la phase cristalline solide et en maintenant la surface rugueuse de la feuille.
