Definitions

  • the invention relates to a method for transferring a decorative section of a stamping foil onto a substrate.
  • the paint package containing highly crosslinking paint systems for example, UV-crosslinking paint systems and / or paint systems with high layer thickness, ie having a thickness greater than 5 microns of the transfer layer without carrier film
  • the separation of the film composite in these cases does not take place at the edge of the application tool but in an undefined position. Due to the strong cross-linking, the formation of comparatively long or very long polymer chains occurs in the paints, whereby the physical properties of the paints are correspondingly influenced.
  • a comparatively hard and brittle paint can break undefined during embossing, with paint flakes different size can arise as unwanted contamination.
  • a comparatively soft and elastic lacquer can not or only incompletely break during embossing or tear undefined, so that in the worst case, no separation edge is formed.
  • stray remnants of the transfer layer formed as a paint package normally form, the aforementioned so-called flakes, which in the further processing of the embossed substrate lead to contamination of the machines and thus to increased cleaning effort. In extreme cases, these flakes can significantly increase the production output.
  • the CH 678835 A5 describes a layer composite with diffractive structures, from the brands are detachable, which can be applied to security documents.
  • the marks are punched out of the layer composite without violating the backing layer of the layer composite.
  • the unneeded parts of the laminate are removed from the security document before the marks are applied.
  • the mechanical stability of the composite layer is determined only by the carrier layer. Trained with the stamped marks carrier layer is rolled up before further processing on a supply roll.
  • the DE 198 13 314 A1 describes an embossing film in which on a carrier film from each other completely separate decorative sections, so-called. Patches are arranged, which can be transferred to a substrate according to the usual procedure in the processing of stamping foils. The formation of the free spaces between the patches is provided by laser radiation, which removes the decorative layer of the stamping foil around the embossing area.
  • the DE 10 2007 005 416 A1 describes an embossing foil and a security sticker formed therewith, wherein a diffractive first relief structure is formed by molding (embossing or replicating) in a replicating layer.
  • a second relief structure is molded at the same time, outside the region which is to be later embossed, the second relief structure being provided in the form of a line-shaped notch or a series of such notches substantially corresponding to an outline of the security label follows and has a notch depth which has more than half the layer thickness of the plastic and / or lacquer layer into which the molding or replication takes place.
  • the object of the present invention is to specify an improved method which combines the advantages of a stable stamping foil with the clean separation of the decorative sections from the carrier foil.
  • the methods according to the invention have the advantage that it is possible with little device complexity to provide at least one predetermined breaking point for detaching the decorative section from the transfer layer in the transfer layer of the stamping foil.
  • This is the hot embossing of stamping foils with highly crosslinking paint systems and / or paint layers high layer thickness with the clean separation of the decorative sections of the carrier film allows.
  • the rest of the embossing foil is peeled off; this is the carrier foil with the parts of the transfer layer which do not belong to the decorative section and have not been embossed onto the substrate, ie the parts of the transfer layer which are still adhering to the carrier foil are detached.
  • embossing foils in which an adhesive layer is applied either to the substrate or to the outside of a transfer layer to be transferred to the substrate, in particular partially in the form of a desired decoration or decorative section and by means of suitable drying or curing, e.g. by means of UV curing, are advantageously processed for transferring the transfer layer from the carrier film to the substrate, wherein a clean separation of the predetermined by the adhesive decor sections and the rest embossing film is formed.
  • the proposed punching of line notches is well applicable in a roll-to-roll manufacturing process.
  • punching the transfer layer is neither thermally nor chemically stressed.
  • the environment is not burdened by pollutant emissions that can occur, for example, during laser cutting.
  • pollutant emissions that can occur, for example, during laser cutting.
  • these may be combustion products of the transfer layer, for.
  • gases such as CO 2 , HCl, NO X.
  • the line-shaped notches locally reduce the thickness of the transfer layer and act as a break notches or predetermined breaking points that form high mechanical stresses in the material of the transfer layer, so that the transfer layer breaks easily in the notch area.
  • the flank angle can be in the range of 20 ° to 90 °. A flank angle of about 60 ° is preferred.
  • open notches are punched into the transfer layer, which are extending between opposite edges of the stamping foil and include the decorative portion.
  • Open notches are here understood notches that are not self-contained, d. H. have one or more start and / or end points.
  • more than one notch is punched in method step b), wherein the more than one notches form a punching area.
  • adjacent notches have a constant spacing.
  • adjacent notches may also be provided that adjacent notches have a varying distance.
  • the distance between two adjacent notches may increase outwardly from a central notch, i. H. the notches directly adjacent to the middle notch have a certain distance to this and further, subsequent notches have a greater distance to these notches.
  • the spacing between adjacent notches has any desired values, that is to say that no symmetry is sufficient as previously described.
  • the punching area may have a width of 0.5 to 2.5 mm, preferably a width of 2 mm. It is ensured with a register accuracy of ⁇ 1 mm, that the decor section is punched register accurate.
  • the notches have a mean width of 0.05 mm to 0.5 mm.
  • notches completely cut through the transfer layer, but terminate in front of the surface of the carrier film facing the transfer layer.
  • the notches sever the transfer layer between 20% and 100%. This ensures that the carrier film is not damaged, so that the carrier film has its full strength even after punching. It has been shown that the intended residue-free separation occurs when the notches cut through the transfer layer in depth by at least 20%.
  • Fig. 1 shows a section of a usable in the roll-to-roll process embossing film 1 with a carrier film 11 and a transfer layer 13, between which a release layer 12 is arranged.
  • an adhesive layer 14 is arranged, which may be, for example, a hot melt adhesive layer, which is thermally activated, or also a cold adhesive layer, which is activated by high-energy radiation act.
  • the transfer layer 13 is a paint package of one or more highly crosslinked paints, for example, a UV-crosslinked paint and optionally from other layers, such as more Coating layers and / or metallic layers and / or a transfer layer with a high layer thickness, ie with a layer thickness greater than 5 microns, especially greater than 10 microns.
  • Hard and brittle transfer layers can form unclean and / or inaccurate separation edges during embossing. In imprints of this type, stray remnants of the transfer layer are frequently formed, so-called flakes, which in the further processing of the embossed substrate lead to contamination of the machines and thus to increased cleaning effort.
  • line-shaped pointed notches 15 with a V-shaped cross section are introduced into the embossing foil 1 from the side of the adhesive layer 14, the depth of which is selected so that the notches 15 on the surface facing the transfer layer 13 the carrier film 11 ends.
  • the flank angle is in the in Fig. 1 illustrated embodiment about 60 °.
  • the carrier film 11 is therefore not damaged by the punching process and has full strength in all areas.
  • These notches act as predetermined breaking points for the transfer layer, because in the notch area high voltages are formed in the notched material.
  • two line-shaped notches 15 are arranged side by side, forming a punching area 15s.
  • the punching area 15s may preferably have a width of 0.5 to 2.5 mm.
  • the punching area 15s delimits a decorative section 16 formed in the transfer layer 13 and in the adhesive layer 14.
  • a boundary line delimiting the decorative section 16 16s is drawn, wherein the punching area 15s outside the Decor section 16 is located.
  • the boundary line 16s can be found in the in Fig.
  • the boundary line 16s delimits the decor section 16 from the remainder of the transfer layer 13, wherein this remaining, adjacent to the decor section 16 transfer layer 13 may be formed, for example, transparent or translucent.
  • the stamping foil 1 alternatively and as for example below in Fig. 5b shown, an endless design without a defined outer edge or outer boundary of a decor or decorative section 16, then a boundary line 16s is not or only partially available.
  • the punching area 15s can lie within the decorative sections 16 not exactly demarcated prior to the punching and / or the decorative sections 16 within the endless design are only defined by inserting the notches 15 in a punching area 15s.
  • Fig. 2 shows the stamping foil 1 Fig. 1 with a modified formation of the notches 15.
  • six line-shaped notches 15 are provided, which protrude only about 20% in the transfer layer 13.
  • the line-shaped notches 15 form as in the above in Fig. 1 described embodiment, the punching area 15s.
  • the two outer notches 15a are exemplarily spaced apart, the four inner notches 15b are formed without spacing between adjacent notches.
  • the two outer notches and the four inner notches each form a group with the same arrangement.
  • the number of notches 15 in the punching area 15s can also be varied.
  • the width of the punching portion 15s may preferably be about 2 mm.
  • the width of the punching portion 15s may preferably be about 2 mm.
  • Fig. 3 shows embodiments of closed dies, ie punching forms, the closed line-shaped notches 15. As the examples show, very different shapes can be formed, so that the design of the decorative sections 16 to be transferred is subject to almost no restrictions.

  • the Fig. 5a shows embodiments of open punching forms, wherein the decorative portion is bounded in each case by at least two spaced-apart line-shaped notches or punching areas. Assuming that the decorative portion to be embossed occupies the entire width of the embossing foil, two line-shaped notches or punching areas are necessary in order to emboss the decorative portion. For example, each of the punch areas may include 2 to 40 line notches.
