Definitions
- the present invention relates to a system for transferring images to substrates (transfer printing), such as textile substrates, in particular T-shirts, cups, magnetic films, mirrors or other smooth surfaces of metal, leather, ceramic, wood, Plexiglas, cardboard or plastic.
- substrates transfer printing
- the invention also relates to a corresponding method for transferring images to substrates.
- Transfer printing i. the transfer of images to substrates, such as textile documents, with the help of so-called.
- Transfer papers on soft the image to be transferred is applied in advance, under increased pressure and temperature conditions, there is often an undesirable background transmission, namely for the transmission of parts of the coating Transfer papers that are not part of the picture.
- additional work steps such as contour cutting on the transfer paper and subsequent weeding off are necessary and / or it must be worked with different temperatures in the preparation of the transfer paper and the actual transfer process.
- the present invention therefore provides a system and method for transferring images to substrates that overcome the aforementioned disadvantages.
- the system according to the invention comprising a combination of essentially two components A and B.
- Component A hereinafter also referred to as transfer sheet, has a layer structure and comprises a carrier and an at least partial toner layer arranged on one side.
- the carrier is, e.g. a film, cardboard or paper, in particular a paper having a basis weight of z. B. about 80-150, preferably about 90-100 g / m2, such as
- CONFIRMATION COPY a machine-smooth paper suitable for (color) copier or (color) laser printer.
- At least one surface of said support or paper i. at least the surface facing the toner has an anti-sticking property.
- non-stick properties are particularly achieved by creating a hydrophobic and / or oleophobic surface by means of impregnation, coating, e.g. with polymers such as polyesters, polypropylenes or fluorocarbons, silicones or refractory waxes, and / or altering the surface structure, e.g.
- Quilon products are chromium (III) -C 4 -C 8 fatty acid complexes, eg CAS 65229-24-5, CAS 15659-56-0, CAS 15242-96-3.
- a corresponding (silicone) coating has tion a separation value of about 100 cN / 20 mm, preferably about
- the surface of the support may optionally be subjected to a further surface treatment to increase the surface tension, in particular according to the invention is a plasma or corona treatment.
- a toner layer is arranged on the correspondingly equipped surface.
- the toner is applied in the form of the desired image.
- the toner layer is at least partially arranged on the surface, i. that at least parts of the surface are covered with toner depending on the geometric shape of the image. Usually, parts of the surface remain free of toner.
- the application is advantageously carried out by means of digital printing, laser printing, in particular by means of (color) copiers or (color) laser printers with commercial toners are used.
- Such toners consist of the corresponding color pigments in a plastic matrix, usually polyester with a melting range of e.g. about 80 - 120 ° C and possibly excipients.
- Suitable toners in the context of the present invention also include water-soluble or solvent-containing inks or sublimation inks, polymer inks, so-called flexo inks, screen printing inks, offset inks or the like.
- the layer thickness of the toner layer is at the usual technical values and is typically 5 to 50, preferably 5 to 20 g / m 2 (in basis weight).
- the support of component A is suitably designed so that under the pressure and temperature conditions of the transfer of the image on the Substrate, ie at temperatures of a minimum of about 100-150 ° C to a maximum of about 200-250 ° C, for example from about 100-250 ° C, especially from about 150 ° C to a maximum of about 200-250 ° C, in particular about 150 - 220 ° C, too
- Back-ground transfer in this case means that in the areas of the surface which are free of toner, parts of the possibly present coating of the carrier are transferred to the substrate.
- high melting point coating materials especially silicones or quilon products, are used which have glass transition or softening temperatures in the range of preferably above about 250 ° C.
- appropriately high-melting coating materials also allows the use of commercially available (laser) printer / copier for applying the toner layer, as far as contamination of the (laser) printer / copier caused by peeling off parts of the coating.
- component A represents a siliconized paper with toner applied thereto in the form of the desired image.
- the carrier of component A is a siliconized and corona-treated paper with a release value of the silicones of above
- the paper may be pre-treated prior to siliconization, such as a coating with e.g. Polyvinyl alcohol or polyethylene.
- the invention therefore also provides a siliconized and corona-treated paper having a basis weight of about 80-150 g / m 2 and a release value of the silicones of about 100-200 cN / 20 mm.
- the paper can be used especially in systems and methods for transferring images to substrates (transfer printing).
- the component B hereinafter also referred to as opaque sheet, likewise has a layer structure and comprises a support, a polymer layer arranged on one side and at least one further layer.
- the carrier is, e.g. a film, cardboard or paper, in particular a paper having a basis weight of z.
- a film, cardboard or paper in particular a paper having a basis weight of z.
- Example about 80-150, preferably about 90-100 g / m2, such as a machine-smooth, suitable for (color) copier or (color) laser printer paper.

- a wax layer which typically has a layer thickness of, for example, between the support surface and the extrusion layer, can be arranged. 10-20 g / m2.
- the extrusion layer serves as an adhesive layer on the substrate in the process of transfer of the image to the substrate. Accordingly, the extrusion layer advantageously has a glass transition or softening temperature which, when separating the support of component B in the heat above the Softening range leads to a cohesive failure in the extrusion layer, so that parts of the extrusion layer adhere to the carrier and so a thin flexible plastic layer is transferred to the substrate.
- the aforementioned separation of the support of component B in the heat takes place after the combination of component A (transfer sheet) and component B (opaque sheet), which by pressing at about 2 - 5 bar in the temperature range of at least about 130 - 150 ° C. to a maximum of about 200-250 ° C, for example from about 130-250 ° C, especially from about 150 ° C to at most about 200-250 ° C, especially from about 150-220 ° C, especially from about 150-200 ° C , Also 180 - 220X, typically for a minimum of about 15 - 20 sec. To a maximum of about 60 sec, in particular about 15 - 45 sec, preferably 15 - 30 sec done.
- the separation of the support of component B in the heat typically takes place in the range of about 0-15 seconds after the pressing process.
- the extrusion layer therefore advantageously has glass transition or softening temperatures in the range of about 60-80 ° C.
- the further layer serves as a background layer for the toner layer of component A. Accordingly, the further layer is advantageously opaque and is referred to below as an opaque layer.
- the opaque layer may be a metal coating applied, for example, by means of a transfer metallization or transfer metallization familiar to the person skilled in the art, in which case a thin (eg 0.05 gm 2 ) metal layer (eg aluminum) is applied to a coated film by means of a vacuum is laminated to the substrate. After a controlled drying process, the carrier film is removed, the metallization remains on the substrate.
- a primer or lacquer may be applied to the metal coating which is optionally corona treated to increase toner adhesion.
- the opaque layer is preferably a white layer.
- the white layer contains 25-75% of a white pigment, for example titanium dioxide, chalk, barium sulfate, zinc sulfide, zinc sulfate or kaolin, preferably titanium dioxide, 75-25% of a plastic binder, which may be a polyolefin, polyolefin copolymer or polyurethane, with reference to the above list referenced by possible substances.
- a white pigment for example titanium dioxide, chalk, barium sulfate, zinc sulfide, zinc sulfate or kaolin, preferably titanium dioxide, 75-25% of a plastic binder, which may be a polyolefin, polyolefin copolymer or polyurethane, with reference to the above list referenced by possible substances.
- the white layer additionally contains an inorganic crystalline substance, in particular silicic acid but also calcium carbonate or benzonite.
- the content of the inorganic crystalline substance is typically about 10 to 30% based on the dry amount of the white layer.
- the opaque layer is advantageously less elastic and possibly has a certain brittleness.
- the layer thickness of the opaque layer is about 2 to 15 g / m 2, preferably 4 to 12 g / m 2, especially 2 to 8 g / m 2, especially 3 to 5 g / m 2.
- the opaque layer advantageously has glass transition or softening temperatures in the range of about 160-180 ° C.
- the opaque layer may also be a combination of metallized coating and white layer.
- component B comprises a transparent layer disposed over the opaque layer.
- the transparent layer suppresses a mixing of the toner with the opaque layer and thus serves to further increase the color brilliance.
- the transparent layer consists of plastics, which have a certain affinity to the toner dyes, that is to record them in their matrix and on the other hand do not give it off again during washing.
- additives such as silica or cellulose esters or other known processing aids can be added.
- plastics are polyesters, polyurethanes, polyacrylates and other compounds, for example homopolymers or copolymers of vinyl acetate, vinyl alcohol, vinyl chloride, vinylidene chloride, methyl and / or ethylacrylic acid or methacrylic acid, maleic acid compounds, styrene and the like
- cellulose esters and cellulose ethers such as ethyl cellulose, benzyl cellulose, cellulose propionates or acetates or butyrates or also polyesters of terephthalic acid or polyamides such as nylon or perlon.
- the layer thickness of the transparent layer is about 2 to 15 g / m 2, preferably 4 to 12 g / m 2, especially 2 to 8 g / m 2, especially 3 to 5 g / m 2.
- the component A (transfer sheet) and the component B (opaque sheet) of the system according to the invention are first joined together under pressure and temperature.
- This is expediently carried out by pressing at about 2 to 5 bar in the temperature range from a minimum of about 130 to 150 ° C. to a maximum of about 200 to 250 ° C., for example from about 130 to 250 ° C., especially from about 50 ° C. to a maximum of about 200 - 250 ° C, especially from about 150 - 220 ° C, especially from about 150 - 200 ° C, typically for a minimum of about 15 - 20 sec. To a maximum of about 60 sec, in particular about 15 - 45 sec, preferably 15 - 30 sec.
- the non-stick properties of the component A ensure that only a connection between the toner layer of the component A and the opaque layer of the component B, or the optionally arranged above transparent layer takes place, but not between the toner-free areas of the component A and the opaque layer of component B, or the optionally arranged above transparent layer.
- the cohesive fracture may also be present in the optional wax layer or in a blend region of opaque layer and extrusion layer or extrusion layer and optional wax layer respectively. Accordingly, the structure of the obtained sandwich structure may vary.
- the system according to the invention is ready for the transfer of the image to a substrate by applying the sandwich structure with the remaining extrusion layer to the substrate and the process being particularly advantageous under pressure and temperature conditions analogous to the printing process. and temperature conditions of the compound of component A and component B.
- This is therefore preferably carried out by pressing at about 2-5 bar in the temperature range of a minimum of about 100-150 ° C to a maximum of about 200-250 ° C, for example from about 100-250 ° C, especially from about 150 ° C to a maximum of about 200-250 ° C, especially from about 150-220 ° C, especially from about 50-200 ° C, also 180-220 ° C, typically for minimal about 15-20 seconds up to a maximum of about 60 seconds, in particular about 15-45 seconds, preferably 15-30 seconds.
- the carrier of component A is then separated or withdrawn in the cold state.
- cold state means below the glass transition or softening temperatures of the layers, preferably in the region of room temperature.
- the system according to the invention preferably consists of a combination of components A and B.
- the method of the invention for transferring images to substrates comprises
- the separation of the support of component B in the heat advantageously above the softening range of the extrusion layer of component B, typically in the range of about 0-15 sec.
- At least about 100-150 ° C to at most about 200-250 ° C for example from about 100-250 ° C, especially from about 150 ° C to at most about 200-250 ° C, especially from about 150-220 ° C, especially about
- the process according to the invention can be carried out with customary devices, so-called transfer presses.
- the step of connecting component A and B and transferring the image to the substrate can be carried out under the same pressure and temperature conditions, which requires particularly simple and rapid process control, since no additional cooling and / or heating phases are necessary , Accordingly, it is advantageous to make no changes to the settings of the transfer press used. Unless otherwise stated or necessarily different from the context, percentages are based on weight, in case of doubt on the total weight of the mixture.
