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 transferred in the copying process.
• 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 base with a smooth, essentially non-porous surface, the transferred display being intended to be arranged largely scratch-resistant on the base.
• any representations can be transferred to a base with a smooth, essentially non-porous surface, the transferred display being intended to be arranged largely scratch-resistant on the base.
• 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 transfer layer having the transferred representation (image) is solved by the carrier in a wet process, applied to the base and then exposed to heat.
• a temperature range between 100 ° C. and 200 ° C., preferably in the range from 120 ° C. to 160 ° C., but in particular around 140 ° C., is preferably selected.
• Loosening is understood to mean a lateral pushing away from the carrier.
• the transfer layer is also pushed onto the support.
• 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 not to a smooth, essentially not porous support such as B. glass, porcelain, ceramic, metal, enamel or plastic apply, ie postpone, dry (remove moisture) and then harden.
• a smooth, essentially not porous support such as B. glass, porcelain, ceramic, metal, enamel or plastic apply, ie postpone, dry (remove moisture) and then harden.
• the representation is preferably copied into a layer of the transfer layer having a perspex 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 have them quasi-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 the carrier, through which the transfer layer can be detached from the carrier when moisture is added.
• the invention also relates to a transfer layer which is detachably arranged on a support such as wood-free paper, for fixing representations transferred in the copying process, the transfer layer being characterized in that it has a sandwich structure with at least two layers in that an outer (first) layer of pigments transferred by the copying process is fixed in position and encloses when exposed to heat, and that a (second) layer arranged below the outer layer is a heat-curing adhesive layer which crosslinks with the substrate to fix the transfer layer on the base.
• the first layer consists of solvent-based plexiglass 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 can be arranged between the transfer layer and the carrier, which is based on dextrin or fatty alcohol.
• Decal paper known per se which is known under the designations "Meta” from Hoffmann and Engelmann or “Twincal” from Britans with a weight per unit area of maximum 120 g per m 2 , can be used as a carrier such as wood-free paper.
• 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 final curing would continue. 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.
