Definitions
- the present invention relates to an ink transfer ribbon which (a) is a flexible one microporous support, (b) optionally one or more intermediate layers and (c) has one or more layers of a transfer color.
- Such ribbons can be found in Type impact printers and typewriters use.
- Transfer ribbons used in typewriters or similar printers usually have a microporous support made of plastic material, which with a Layer of a transfer ink is coated, which among other things oil and the Printing process on the paper transferred material can contain.
- the microporosity of the Carrier is an important prerequisite for adequate anchoring of the Color layer (s) on the carrier.
- symbols are opened Substrates printed, with the transferred symbols either permanently on the substrate stick or can be removed with the help of an adhesive tape, which corrections allowed.
- Such ribbons are usually wound or installed on spools used in ribbon cartridges in typewriter typewriters or printers.
- the Ribbon cartridges allow easy insertion of the ribbon into the machine.
- the transfer color layer is usually applied to the substrate from one Melt or from a solution in a solvent.
- US-A-3 825 470 describes a correctable transfer ribbon.
- MICR magnetic ink character recognition.
- the layer of Transfer ink can have a sponge structure, with a small one when the type is turned up Amount of color is pressed out and transferred to the substrate.
- the layer of Alternatively, transfer ink can also be detached and transferred over the entire surface.
- the layer of the transfer ink generally contains oils or oily ones Modifiers, e.g. Fatty acid alkyl esters, which after the order in the microporous carriers can migrate. This can be the case with transfer ribbons, in particular narrow-width ones, causing problems when being transported by the printer mechanism to lead. If e.g. Oil can escape from the ribbon onto the transport mechanism Presence of the oil during transport of the belt to increased tensile resistance and even cause the carrier to get caught, causing the belt to move away from the transport mechanism is no longer moved. In addition, the oil when it is on the drive wheel reached, exert a lubricant effect and cause the tape to slip, so that the tape does not continue.
- oils or oily ones Modifiers e.g. Fatty acid alkyl esters
- EP-A-0 167 932 proposes to combat oil migration through the Backing film caused problems with a backing layer.
- This back layer ensures a clean friction surface and good contact with the drive device.
- the backing layer can be a polyester, a vinyl chloride resin or a polyurethane resin as well as a filler containing silica. From the disclosure of EP-A-8-0 167 932 shows that this backing layer acts as a barrier for oil migration. A Increasing the surface roughness is not addressed. Nor does it turn EP-A-0 167 932 addresses the problems associated with electrostatic electricity. Another disadvantage is that a separate manufacturing step Back layer must be applied to the back of the carrier.
- US-A-4 675 233 describes an ink transfer material for printers which is biaxial oriented polyester film and a transfer ink layer, the biaxial oriented polyester film with a thickness of 1 to 15 ⁇ m and the rough surface Has an average roughness of 0.02 to 1 ⁇ m and a maximum height of 0.2 to 10 ⁇ m.
- polyester films are not microporous and provide a barrier layer for that Oil migration. Therefore polyester films are for use as carrier materials for Ribbons unsuitable for type printers and typewriters.
- this object is achieved by an ink transfer belt, which is characterized in that the back of the support has a surface roughness of a roughness depth R t of at least 400 nm and a mean roughness value R a of at least 40 nm.
- the roughness depth R t is the distance between the basic and reference profile of a surface profile, ie the maximum mountain-valley distance.
- the average roughness value R a is the mean absolute distance between the reference profile and the actual profile, which is also referred to as CLA (center line average), ie the arithmetic mean of the deviations of the profile from a center line.
- the "mountains” on the back of the carrier prevent the formation of a contiguous oil film, which has an undesirable tendency to adhesion Band surface of the adjacent turn or other surfaces shows.
- the mountains” also act as a spacer and prevent full area contact the back of the belt with other surfaces, which is the frictional resistance and Unwinding resistance significantly reduced.
- carrier foils for printer ink ribbons are usually produced by casting from the melt flow, using a slot nozzle as the pourer, from which the melt falls onto a cooled casting surface (drum or belt) or is poured into a water bath.
- the film properties such as porosity, tensile strength and surface roughness, depend very much on the crystallinity, the molecular weight distribution and the production conditions, which is why the selection of usable raw materials is currently very limited.
- Two suitable HDPE qualities for carrier films are, for example, M5395 / 1 from Lyondell and 6340/3 from DuPont.
- the surface roughness of these conventional carrier films varies greatly depending on the batch, but the values for R t and R a are always well below 400 and 40 nm, respectively.
- R t is 400 to 5000 nm and R a is 40 to 500 nm, in particular R t is 600 to 2500 nm and R a is 70 to 250 nm. R t is at least 650 nm and R a is at least 80 nm.
- FIGS. 1 and 2 The effect of different roughness depths or a different mean roughness value of the carrier on the drive torque of an ink ribbon cassette is shown in the attached FIGS. 1 and 2.
- R t and R a were varied by varying the particle size and concentration of the filler of an ink ribbon carrier produced as described below. It can clearly be seen that the required torque decreases with increasing R t or R a .
- R t and R a were determined using a form TALYSURF series 2 laser device (from RANK TAYLOR HOBSON Inc.). The roughness was determined in accordance with BS 1134.
- the required surface roughness of the microporous support is preferred by using a particulate filler e.g. in extrusion a thermoplastic is incorporated into the carrier film.
- suitable Filling materials include calcium carbonate, diatomaceous earth, clays, glass, Hollow glass particles, aluminum silicates, gypsum, magnesium carbonate, talc, calcite, fibers, Lime, mica, amorphous silica, other silicates, etc.
- a particularly preferred The filler is micronized PTFE, e.g. by MICRO POWDERS Inc., USA, at the name FLUO HTG is available. It has a softening point of over 316 ° C and remains in the melted thermoplastic at around 260 ° C Get particles.
- the filler preferably has a relatively low abrasiveness in order to not subject the extrusion nozzle to excessive wear.
- the filler should also at the melting temperature of the thermoplastic plastic of the carrier film be stable.
- Thermoplastic is a thermoplastic for the carrier film Suitable plastics that are microporous in a thin layer. Of these are polyolefins preferred, especially polyethylene (HDPE, LDPE, LLDPE) and polypropylene, ethylene-propylene propolymer as well as mixtures thereof.
- the quality of the film starting material and the exact play Manufacturing conditions of the film are not critical.
- the film can be used for any Methods, e.g. by melt casting on a cooled drum, melt casting in one Water bath, injection molding with subsequent stretching or blowing.
- Typical melting temperatures for polyethylene are about 80 to 150 ° C, especially about 105 to 140 ° C.
- the cooled drum is usually at a temperature of 10 to 35 ° C or the water bath at a temperature of 50 to 70 ° C.
- a particular particle size distribution of the filler is preferably observed.
- the average particle size of the filler is preferably between 0.5 and 15 am, especially between 2 and 8 ⁇ m. Smaller particle sizes achieve the desired Effect not optimal.
- the use concentration is preferably between 500 and 100000 ppm, in particular between 1000 and 10000 ppm.
- the carrier film is usually in a thickness of 6 to 30 ⁇ m, in particular 8 to 16 ⁇ m, extruded.
- no further layer (s) are (are) on the back of the support. arranged.
- Preferred color transfer ribbons have at least one transfer color layer which 10 to 35% by weight of a binder, in particular in the form of a polyamide resin, 30 up to 55% by weight of mineral oil and / or fatty acid esters and 25 to 35% by weight of one Color material selected from pigments and in the other ink components insoluble organic dyes.
- the transfer color layer can also Waxes, especially synthetic waxes, contain.
- the wording of the Transfer color layer is in dissolved / dispersed form in a volatile solvent deposited on the carrier.
- a suitable solvent is a mixture of Isopropyl alcohol and toluene. The solvent is then evaporated, for example by transferring heated air.
- This example explains the production of a carrier for an inventive one Transfer ribbon made of polyethylene / filler.
- HDPE granules (grade M 5395/1 from Lyondell) were extruded with 5000 ppm calcium carbonate (Snowcal 40 from Croxten & Garry) to form a film with a thickness of 12 ⁇ m.
- the filler was added as a separately made concentrate (20% filler in HDPE) at a concentration of 2.5% to the main stream of HDPE during the extrusion process.
- This example illustrates the production of a carrier of an inventive Transfer ribbon made of polypropylene / filler.
- Polypropylene granules (Hostalen PPU 1080 F from Hoechst, Germany) were extruded with 6000 ppm of silica (Tamsil 10, particle size 0.4 to 6 ⁇ m, from Lawrence Industries) into a film with a thickness of 12 ⁇ m.
- the filler was again added as a separately prepared concentrate (15% filler in LLDPE) at a concentration of 4%.
- the carrier films obtained in the preceding examples were coated with a coating composition according to formulation A (correctable ink) or B (MICR ink) and the solvent was evaporated off.
- the transfer ribbons obtained showed excellent printing behavior and ran with minimal effort in ribbon cartridges.
