Definitions

  • the invention relates to a multilayer, flexible transfer tape with an auxiliary carrier and a pressure-sensitive adhesive layer, a binder-containing transfer layer being present between the auxiliary carrier and the pressure-sensitive adhesive layer, which has a stronger adhesion to the pressure-sensitive adhesive layer than to the auxiliary carrier.
  • various possibilities have been known according to which pigmented liquid systems can be used to cover incorrect written representations.
  • white pigmented dispersions containing a volatile organic solvent are applied with a brush to correct characters and the like. Evaporation of the volatile organic solvent leads to environmental pollution. You must wait a relatively long time before the evaporation is complete and a new overwrite is possible. Applying the correction dispersions with a brush usually does not provide an even top coat.
  • GB-A-1 036 743 describes a multilayer transfer sheet which has a color-releasing layer between a base layer with a plastic binder and a cover layer with a binder made of plastic and / or waxes. Ethyl cellulose can be incorporated into the color-releasing layer. Such a transfer sheet should be usable in writing programs.
  • the invention was based on the object of further developing the transfer belt mentioned at the outset so that the binder-containing transfer layer can be applied cleanly and with sharp edges to the area or area to be covered (also over a large area) and can be used in a rolled-up form in a hand-held device for simple, fast and uniform use Application to the respective substrate is possible, with stringing of the pressure-sensitive adhesive layer should be excluded when tearing.
  • the binder-containing transfer layer contains 0.5 to 5% by weight of a soluble cellulose derivative as a tear-off aid.
  • the auxiliary carrier of the flexible transfer belt according to the invention preferably consists of a plastic film, as is used for the carriers of typewriter ribbons, e.g. made of polyethylene terephthalate, polypropylene, polyethylene, polyvinyl chloride, polycarbonate. Silicone-coated paper has also proven to be suitable as an auxiliary carrier.
  • the silicone coating leads to a reduction in the adhesive tension between the binder-containing transfer layer and the auxiliary carrier.
  • the silicone coating can also be replaced by other non-stick agents, such as polytetrafluoroethylene.
  • the auxiliary carrier preferably has a thickness of 10 to 60 ⁇ m, in particular 15 to 55 ⁇ m, the cover layer a thickness of 5 to 40 ⁇ m, in particular 15 to 25 ⁇ m, and the pressure-sensitive adhesive layer a thickness of 1 to 8 ⁇ m, in particular 2 to 5 ⁇ m.
  • a thickness ratio of the pressure-sensitive adhesive layer to the transfer layer of 1: 4 to 1:12, in particular 1: 8 to 1:10, is expediently chosen.
  • the pressure sensitive adhesive layer can consist of commercially available pressure sensitive adhesives. These are materials that are elastic and permanently adhesive self-adhesive compositions with high adhesive forces and that adhere immediately to the various surfaces even under low pressure at room temperature. They are preferably in aqueous solution applied to the transfer layer already on the auxiliary carrier, since the already formed binder-containing transfer layer is not dissolved again. Among pressure-sensitive adhesives of this type, those based on acrylate are particularly advantageous.
  • the starting materials can be viscous solutions or dispersions based on rubber, polyacrylates, polyvinyl ethers or polyvinyl isobutylene. Materials based on polyacrylates are preferred.
  • the pressure-sensitive adhesive material to be applied which is regularly present in an aqueous medium, preferably contains wetting agents or surfactants (sold under the trade name Byk W).
  • the above-mentioned solutions or dispersions of the pressure sensitive adhesive for forming the pressure sensitive adhesive layer are preferably applied to the transfer layer in an amount of 1 to 5 g / m2, very particularly preferably in an amount of 2 to 4 g / m2.
  • the type of plasticizer used should also be considered when choosing the respective binder for forming the transfer layer.
  • a plasticizer should be used which, when the transfer layer is applied to the surface to be corrected or to be covered, does not penetrate through the normally thin pressure-sensitive adhesive layer and comes into contact with the area to be corrected or the colorants located there, and this is more troublesome Way, coloring the transfer layer.
  • common plasticizers such as silicone, castor and mineral oil are suitable for this.
  • plasticizers preferred in other areas of application such as phthalic acid esters and oleic alcohol, are not equally suitable.
  • a so-called ⁇ varnish agent '' can be incorporated into the binder-containing transfer layer, which may migrate or make insoluble colorants so that they do not migrate into the applied transfer layer and color it again.
  • Suitable varnishing agents include tannin and tannin derivatives.
  • lacquering agents as are known from the technical field of inks and inks, can be used. They should preferably be present in the binder-containing transfer layer in an amount of 0.5 to 5% by weight, in particular 1.5 to 3.5% by weight. The value of 2 to 2.5% by weight is very particularly preferred.
  • the binder chosen in each case for forming the transfer layer is preferably transferred into a solution or used as a dispersion in the presence of a polymer dispersion.
  • the choice of solvent depends on the type of binder used.
  • Low to medium-boiling organic solvents from the group of alcohols, such as ethanol, isopropanol and butanol, the ketones, such as acetone and methyl ethyl ketone, the esters, such as methyl and ethyl acetate, the aromatic hydrocarbons such as toluene and the aliphatic hydrocarbons, such as, are preferably used Petrol in the boiling range of 70 to 140 ° C, alone or in a mixture, as well as water, alone or in a mixture with low-boiling, water-soluble organic solvents.
  • the concentration of the binder in the solution or dispersion is not essential to the invention.
  • this solution or dispersion is preferably applied to the auxiliary carrier in an amount of 15 to 25 g / m2 and very particularly preferably between 18 and 22 g / m2.
  • the term “colorant” is to be understood as far as possible. It is supposed to be the collective name for all coloring substances, so that this includes dyes and pigments, the latter also having a filler character. Dyes are to be understood as meaning those colorants which are soluble in water, organic solvents or binders and which are opposed by the insoluble pigments. The coloring can be present immediately, but can only appear through fluorescence. The latter applies, for example, to fluorescent fluorescent colors. If the transfer belt according to the invention is used for the correction of characters and pictorial representations and the like, the binder-containing transfer layer contains in particular white pigments, such as titanium white, precipitated chalk, clay or colloidal silicas.
  • inorganic pigments such as chrome yellow, ocher, iron oxide red, cobalt blue, ultramarine, Berlin blue, or organic pigments such as alkali blue, phthalocyanines, azo dyes, anthraquinones, metal complex pigments as well as carbon blacks and iron oxide black are used as colorants , used.
  • organic pigments such as alkali blue, phthalocyanines, azo dyes, anthraquinones, metal complex pigments as well as carbon blacks and iron oxide black are used as colorants , used.
  • fluorescent dyes are: Blaze Orange T 15 from Dayglo, Maxilonbrillantflavin 10 GFF from Ciba Geigy, pyranine from Bayer AG and Basonyl-Red 540 from BASF.
  • the optimum covering function of the transfer belt according to the invention in particular that of the transfer layer containing the binder, can be controlled by the pigment content.
  • the optimal pigment content depends on various factors, such as the type of binder chosen, the pigment itself and the other additives incorporated. A particularly critical value or critical range cannot be specified.
  • the binder / pigment relationship could give a weight ratio of 1: 1 to 1:12, in particular 1: 3 to 1: 8 and very particularly between 1: 4 to 1: 7.
  • An essential component of the binder-containing transfer layer of the transfer belt according to the invention is a ⁇ tear-off aid ''. Only when such a tear-off aid is used is it ensured that when the transfer layer is applied to a substrate a clean tear-off takes place. Surprisingly, it has been shown that a relatively limited group of compounds has the desirable properties as a tear aid in the context of the invention, namely soluble cellulose derivatives.
  • Particularly preferred cellulose derivatives are the cellulose ethers soluble in organic solvents and / or water, such as methyl, ethyl, hydroxyethyl, ethylhydroxyethyl and carboxymethyl celluloses, cellulose esters such as cellulose acetate acetobutyrate and propionate.
  • a variety of other soluble cellulose derivatives are suitable which have the desired effects. It appears that the basic cellulose structure in the soluble cellulose derivative is important, while the groups introduced, such as the ethyl group, etc., result in the derivative formed being soluble in the solvent chosen in each case.
  • the amount of the tear-off aid incorporated in the transfer layer is 0.5 to 5% by weight, in particular 1.5 to 3.5% by weight.
  • the range of 2 to 2.5% by weight is particularly preferred.
  • the quantitative ratio of demolition aid to binder could also be used as the basis for forming the transfer layer.
  • the ratio of demolition aid to binder could be given as 1: 2 to 1:20, the range from 1: 4 to 1:10 being preferred.
  • these further additives can be incorporated.
  • These can be agents for improving the covering power, such as, in particular, aluminum silicate, tinting agents, such as, for example, carbon black, or the already mentioned lacquering agent, in particular for basic dyes in the form of, for example, gallic acid derivatives, e.g. Printan from Ciba Geigy.
  • the materials of the individual layers of the transfer belt according to the invention described above generally meet the basic requirement that the adhesive tension (defined by the work of adhesion according to Dupre's equation, Lit .: KL Wolf “Physics and Chemistry of Interfaces", Springer Verlag 1957, p 164) between the pressure-sensitive adhesive layer and the transfer layer is larger than that between the auxiliary carrier and the transfer layer. If this is not the case in individual cases, then a suitable non-stick layer would have to be applied to the auxiliary carrier in order to meet this basic requirement. In such cases, a further requirement is regularly met, according to which the transfer layer formed on the substrate is non-adhesive to other materials that come into contact with it, in particular paper.
  • the following adhesive tension ratios for the successful use of the transfer tape according to the invention can be specified, the symbol "S" representing the adhesive tension ratio between the different materials, so S1 paper / adhesive layer, S2 transfer layer / adhesive layer, S3 transfer layer / auxiliary carrier, S4 transfer layer / paper and S5 pressure-sensitive adhesive layer / auxiliary carrier and, if possible, to comply with the following requirements: S1 greater than S3, S2 greater than S3 ⁇ S5 very much smaller than S2 and S5 smaller than S3.
  • the free surface of the transfer layer applied to a substrate, in particular paper should shows no adherence to the outside, ie S dh is then zero or strives towards zero. In other words, this means that the applied transfer layer should be non-stick when touched by hand or paper.
  • the advantageous method for producing the transfer belt according to the invention is characterized in that a suitable plastic solution, which contains the tear-off aid mentioned, according to customary application technologies, e.g. a squeegee is applied to an auxiliary support in the form of a flexible film, the solvent is evaporated at elevated temperature, an aqueous dispersion containing a pressure sensitive adhesive is applied to the formed transfer layer containing binder and then the water using conventional squeegees, for example with a squeegee or a roller coater is evaporated.
  • a suitable plastic solution which contains the tear-off aid mentioned, according to customary application technologies, e.g. a squeegee is applied to an auxiliary support in the form of a flexible film, the solvent is evaporated at elevated temperature, an aqueous dispersion containing a pressure sensitive adhesive is applied to the formed transfer layer containing binder and then the water using conventional squeegees, for example with a squeegee or a roller
  • the user takes the housing in his hand and uses the application foot to press the outer (removable) tape layer running over its end edge against the substrate to which it is to be transferred (e.g. a printed sheet of paper to make corrections ).
  • the user moves the device relative to the substrate and transfers z.
  • the transmission tape according to the invention is particularly distinguished as a correction means in the office, school and household for covering faulty characters, markings and graphic representations and rewriting.
  • Another use of the transfer belt can be the strikingly colored marking of areas, fonts and / or characters.
  • the transfer belt then carries a transfer layer containing a colored pigment.
  • Another use is to highlight text passages, characters or pictorial representations.
  • the transfer layer is preferably transparent and colored with a colorant that fluoresces in daylight.
  • the transmission tape according to the invention can be easily, quickly and evenly z.
  • B. Apply top layers containing in particular colorants to substrates. If the transfer layer of the transfer tape according to the invention is transparent, for example does not contain any covering pigments, then it can be used for the mere covering without color effect and preservation of characters that are otherwise sensitive to the effects of air and the like.
  • the following dispersion is first produced to form the colorant-containing transfer layer: Solvent-soluble polyurethane (Permuthane U 4924) (25% in isopropyl alcohol / toluene, mixing ratio 1: 1) 19.0 parts by weight Isopropanol 10.0 " toluene 35.0 " Printan G 1.0 " Ethyl cellulose N7 (tear aid) 1.0 " Titanium dioxide (Kronos RN34) 29.0 " Aluminum silicate P820 5.0 " (Means to improve opacity) soot (Printex 140V) (tinting agent) 0.01 " 100.01 parts by weight
  • the PSA was applied with a doctor knife in a thickness of 2 g / m2. Then the water portion was evaporated at about 100 ° C by passing hot air over it.
  • the transfer tape obtained was particularly suitable for covering characters written on paper. It led to the quick and even application of an immediately rewritable cover strip. The application was carried out using a commercially available hand roller.
