Decorative labels and method of their production

Method for the production of decorative labels, comprising the steps of:

• a) applying (i) an embossing film capable of transferring heat and comprising a carrier layer, a separation layer, at least one decorative layer and a melt adhesive layer that can be heat-activated in the range of 110.degree. to 230.degree. C. on (ii) a substrate comprising a separation paper, an adhesive layer and a plastic film comprising homopolymers or copolymers of ethylene having a crystallite melting point of 110.degree. to 120.degree. C., a heat of fusion of 125 to 180 J/g and a melt index of 2.0 to 3.5 g/10 min., in manner such that the melt adhesive layer of the embossing film (i) and the plastic film of the substrate (ii) face one another;
• b) first bonding the embossing film (i) and substrate (ii) over an entire area via the melt adhesive layer at a temperature of 110.degree. to 200.degree. C., under a pressure of 1.0 to 5.5 bar and for a period of 1 to 0.01 sec., and
• then embossing the combination of the embossing film (i) and substrate (ii) with a heated stamp having a stamp area bearing a certain motif and raised edges in comparison to an interior of the stamp area, said stamp acting on the carrier layer of the embossing film (i) so that
• within the stamp area, the separation layer, at least one decorative layer and melt adhesive layer of the embossing film (i) and the plastic film and adhesive layer of the substrate (ii) are fused and punched through in the area of the raised edges of the stamp;
• c) removing the carrier layer of the embossing film (i);
• and
• d) removing parts of the embossing film (i) and the plastic film and adhesive layer of the substrate (ii) lying outside confines of the stamp motif (stamp area);
• whereby a label having an unimpaired decorative motif is produced without warping of the film or blurring of the pattern.

C. (ii) a substrate comprising a separation paper, an adhesive layer and a plastic film comprising homopolymers or copolymers of ethylene having a crystallite melting point 110.degree. to 120.degree. C., heat of fusion of 125 to 180 J/g and melt index of 2.0 to 3.5 g/10 min, in a manner such that the melt adhesive layer of the embossing film (i) and the plastic film of the substrate (ii) face one another;
• b) first bonding the embossing film (i) and the substrate (ii) over an entire area via the melt adhesive layer at a temperature of 110.degree. to 200.degree. C., under a pressure of 1.0 to 5.5 bar and for a period of 1 to 0.01 sec.,
• then removing the carrier layer of the applied embossing film (i),
• applying a second embossing film (iii) with a different decoration consisting of a carrier layer, separation layer, at least one decorative layer and a melt adhesive layer which can be activated at 110.degree. to 230.degree. C. on a part of the first embossing film (i) remaining on the substrate (ii), in a manner such that the melt adhesive layer of the second embossing film (iii) faces the at least one decorative layer of the first embossing film (i),
• embossing the second embossing film (iii) upon the at least one decorative layer of the first embossing film (i) with a stamp having an area exhibiting an area-recessing, outer contour pattern with raised edges, at a temperature of 110.degree. to 230.degree. C., under a pressure of 1.0 to 7.0 bar and for a period of 3 to 0.3 sec., so that
• in an immediate area of contour patterns of the stamp, the first (i) and second (iii) embossing films are bonded to one another via the melt adhesive layer, and
• in an area of the raised edges of the stamp, the separation layers, decorative layers, and melt adhesive layers of the embossing films (i) and (iii) along with the plastic film and the adhesive layer of the substrate (ii) are fused and punched through;
• c) separating the carrier layer of the second embossing film (iii) and parts of the second embossing film (iii) that are not connected with the first embossing film (i);
• and
• d) removing parts of the first embossing film (i) and parts of the plastic film and adhesive layer of the substrate (ii) lying outside confines of the contour pattern (stamp area);
• whereby a label having an unimpaired decorative motif is produced without warping of the film or blurring of the pattern.

C. on a part of the first embossing film (i) remaining on the substrate (ii), in a manner such that the melt adhesive layer of the second embossing film (iii) faces the at least one decorative layer of the first embossing film (i),
• embossing the second embossing film (iii) upon the at least one decorative layer of the first embossing film (i) with a stamp having an area exhibiting an area-recessing, outer contour pattern with raised edges at a temperature of 110.degree. to 230.degree. C., under a pressure of 1.0 to 7.0 bar and for a period of 3 to 0.3 sec., so that
• in an immediate area of contour patterns of the stamp, the first (i) and second embossing (iii) films are bonded to one another via the melt adhesive layer, and
• in an area of the raised edges of the stamp, the separation layers, decorative layers, and melt adhesive layers of the embossing films (i) and (iii) along with the plastic film and the adhesive layer of the substrate (ii) are fused and punched through;
