A method is provided for producing a unique printable multi-layer composite structural material (10B), and in turn a unique scratch-resistant, self- laminated printed material (10A). A printable multi-layer composite structural material is formed which includes a first underlying substrate (11) capable of being transported through a printing device, a second layer (16) formed on the first layer which is flowable when heated to at least its melting point and being fusible below its melting point, and a third layer (22) formed on the second layer which is printable. The third layer is also permeable so that when the second layer is in a flowable state it permeates through and about said third layer. The printable multi-layer composite structural material is capable of forming a scratch-resistant, self-laminated printed material by (a) printing a predetermined image (26) onto the third layer, (b) heating the second layer until it is in a flowable state and permeates through and about the third layer and about the predetermined image, and (c) fusing the flowable second layer by lowering its temperature below its melting point thereby encapsulating said third layer and the predetermined image.

L'invention concerne un procédé permettant de produire un matériau (10B) structurel composite multicouche imprimable unique, permettant d'obtenir à son tour un imprimé (10A) auto-stratifié résistant aux rayures. Un matériau structurel composite multicouche imprimable est constitué d'un premier substrat (11) sous-jacent capable de passer dans un dispositif d'impression, d'une seconde couche (16), formée sur la première, liquéfiable lorsqu'on la chauffe à une température au moins équivalente à son point de fusion, et fusible aux températures inférieures à son point de fusion, et d'une troisième couche (22) imprimable formée sur la seconde couche. Cette troisième couche est également perméable de manière que lorsque la seconde couche est à l'état liquide, elle passe à travers et autour de la troisième couche. Le matériau structurel composite multicouche imprimable peut constituer un imprimé auto-stratifié résistant aux rayures conformément au procédé suivant, à savoir (a) imprimer une image (26) prédéterminée sur la troisième couche, (b) chauffer la seconde couche jusqu'à ce qu'elle devienne liquide et qu'elle passe à travers et autour de la troisième couche et autour de l'image prédéterminée, et (c) faire fondre la seconde couche liquéfiable en abaissant sa température au-dessous de son point de fusion, ce qui permet d'encapsuler la troisième couche et l'image prédéterminée.
