Definitions

  • the invention relates to a method for transferring, in particular, colored representations to smooth documents, in that the representation is transferred to a transfer layer applied to a carrier in the copying process. Furthermore, the invention relates to a transfer layer, which is arranged on a carrier such as wood-free paper, for fixing representations transmitted in the copying process.
  • the base In order to transfer the representations, on the one hand the base must have a porous surface and on the other hand a hot or hot press is necessary in order to carry out the transfer to the base if there is considerable pressure.
  • EP 0 118 084 A1 discloses a support for decals or decals on which a water-soluble separating layer for one-sided reception of a detachable printing and / or lacquer layer is applied.
  • EP 0 380 356 A2 describes a decal or a method for transferring e.g. B. described xerographically produced images. A paper is used as the carrier which is soaked with solids in such a way that there is no porosity. The image to be transferred is applied to the carrier directly or on a plastic film applied thereon. In the former case, the picture must then be covered with a plastic film. Then there is a transfer to a porous object, the plastic film always being on the outside.
  • the present invention is based, inter alia, on the problem of developing a method of the type mentioned at the outset in such a way that any representations can be transferred to a support with a smooth, essentially non-porous surface, the transferred display being to be arranged largely scratch-resistant on the support.
  • any representations can be transferred to a support with a smooth, essentially non-porous surface, the transferred display being to be arranged largely scratch-resistant on the support.
  • there should be a simplification so that even laypersons can carry out a corresponding transfer.
  • the problem is essentially solved according to the invention in that the image is copied onto or into the transfer layer, in which pigments transferred by the copying process are fixed in position, and in that the transfer layer having the transferred representation (image) is first removed from the support by the wet process, then with the Transfer layer to the base is applied to this and then hardened.
  • a temperature range between 100.degree. C. and 200.degree. C., preferably in the range from 120.degree. C. to 160.degree. C., but in particular around 140.degree. C., is preferably selected.
  • Loosening is understood to mean a lateral pushing away from the carrier.
  • the transfer layer is also pushed onto the pad.
  • any representation that is to say personal images, newspaper clippings, drawings or the like, can preferably be transferred to the transfer layer on the carrier in a xerographic copying process in order to solve this as a cold transfer in the wet process and on a smooth, essentially non-porous base such as B. glass, porcelain, ceramic, metal, enamel or plastic, i.e. postpone, dry (remove moisture) and then harden.
  • a smooth, essentially non-porous base such as B. glass, porcelain, ceramic, metal, enamel or plastic, i.e. postpone, dry (remove moisture) and then harden.
  • the representation is copied into a layer of the transfer layer, preferably made of plexigum material, in order to fix pigments transferred by the copying process and then to enclose the pigments by the action of heat, that is to say to allow them to be sealed. This results in a high durability of the picture and a smooth surface.
  • separating layer containing dextrin and / or fatty alcohol between the transfer layer and your support, through which the transfer layer can be detached from the support when moisture is added.
  • the invention also relates to a transfer layer, which is arranged on a support such as wood-free paper of a maximum of 120 g per m 2 , for fixing representations transmitted in the copying process, the transfer layer being distinguished thereby.
  • this has a sandwich structure comprising at least two layers has that a (first) outer layer fixes pigments transferred by the copying process and encloses them when exposed to heat, and that a (second) layer arranged below the outer layer is a heat-curing adhesive layer that crosslinks with the substrate to fix the transfer layer on it .
  • the first layer consists of solvent-based Plexigum material with plasticizer.
  • the adhesive layer is based on synthetic resin.
  • the adhesive layer preferably consists of a mixture of synthetic resin with hardener additive and plexigum on solvent base with plasticizers.
  • the proportion of synthetic resin and plexiglass can be approximately the same size.
  • a separating layer which is based on dextrin or fatty alcohol can be arranged between the transfer layer and the carrier.
  • decal paper known per se can be used, which is known under the names "Meta” from Hoffmann and Engelmann or “Twincal” from Britans with a basis weight of maximum 120 g per m 2 .
  • the separating layer between the carrier and the transfer layer has dextrin and / or fatty alcohol. This allows the transfer layer to be easily detached from the carrier by means of moisture. Moisture is understood here not only to mean water, but also water vapor in order to dissolve the intermediate carrier material in this way.
  • a representation to be transferred is placed on a dry copier in order to copy the representation onto a transfer layer arranged on a carrier.
  • the transfer layer has a sandwich structure with at least one outer fixing layer and an adhesive layer covered by this.
  • the fixing layer consists of solvent-based plexigum with plasticizer. This layer is relatively soft and therefore suitable for absorbing and fixing the toner.
  • the layer thickness is approximately 0.15 mm.
  • the adhesive layer consists of an approx. 1: 1 mixture of synthetic resin with the corresponding hardener additive and solvent-based plexigum with plasticizer. This layer is designed so that it is relatively hard and brittle, but has very good cross-linking properties with the new base.
  • the layer thickness is approximately 0.05 mm.
  • the image After the image has been transferred to the transfer layer, the image is cut out along its outline and placed in lukewarm water. After about 1 minute, the transfer layer detaches from the carrier in such a way that the transfer layer having the image can be pushed away from the carrier. The free transfer layer with the The image is then pushed directly onto a base to be provided with the image, which has a smooth, essentially non-porous surface. With a rubber squeegee or a soft cloth, the moisture under and above the layer thus transferred is removed like water.
  • a chemical hardening process takes place, which is started at a temperature between 140 ° C. and 180 ° C. in the fixing unit of the copying system and without further application of heat for 4 to 6 days until the final hardening would last. This time can be shortened, however, if heat is placed in the range of approx. 140 ° C over a period of approx. 10 minutes after arranging the intermediate carrier material on the base.
