Definitions
- the invention relates to a multilayer material and a method for producing the multilayer material, consisting of a heat-activable carrier film based on polyester and having a defined shrinkability, which is coated with a polymer and optionally a thermoplastic pressure sensitive adhesive and optionally a toner or ink receiving layer or a metal layer .
- Such multilayer materials are suitable for covering large areas of carrier frames in model aircraft construction and for one-person aircraft / ultralight aircraft. However, they are also suitable as image and print receiving materials for copying machines working with normal paper and are used as weather-resistant, self-adhesive labels, marking materials or in advertising.
- Colored polyester films for example made of polyethylene terephthalate, are suitable and known due to their physical and chemical properties for covering large areas of aircraft models. Such films are also due to their weather resistance and high thermal resilience one-sided application of a toner or ink receiving layer is known as an image and print receiving material for copying machines working with normal paper.
- polyester carrier films are provided with a heat-activatable, pigmented and / or colored polymer adhesive layer.
- polyester carrier films are known in which a pigmented thermosetting polymer layer is connected to the carrier film via a thermoplastic polymer layer and a further thermoplastic polymer layer is applied as an adhesive layer. Such films usually have a relatively high weight.
- Fibrous carrier materials in tissue form made of polyester with resin impregnation are also known as the material for covering base-wood frames in aircraft model construction; the resin solutions used for the impregnation can be colored by pigments and / or organic dyes.
- a disadvantage of these known technical solutions is, for example, that a decrease in the adhesive strength can be observed for those materials whose coloring is achieved by applying pigmented adhesives.
- the visual impression of the covering materials produced in this way is heavily dependent on the application and processing conditions and continuous quality is therefore not guaranteed. Due to the thermoplasticity of such adhesives, when the corners and edges are reclamped, color tearing occurs and the paint / adhesive layer escapes at the edges. Even when the adhesive layer is accidentally brought together and / or when the surface materials are corrected, Color structure will be destroyed.
- thermosetting colored layer of which is embedded between two thermoplastic polymer layers, namely the primer and adhesive the smallest holes can be formed in the colored layer.
- the curing agent for example isocyanate
- gases for example CO 2 , water
- Conventional toner layers are usually made using bicyclic alkyl, 1-12-C aliphatic alkyl or aromatic - (meth) -acrylate with up to 20% of a polar monomer or N, N-dialkyl-mono-alkylamino-alkyl- (meth) acrylate formed.
- Solutions of polymerized diol-di- (meth) -acrylate with additions of copolymerized vinyl monomer and copolymerized vinyl ester, (meth) -acrylic acid ester and / or styrene are also known.
- Transparent, aqueous toner-receiving layers made of water-soluble polymers, with polymer particles of size 1 to 15 ⁇ with additions of antistatic agents are also frequently used.
- Toner fixing layers made of polyvinyl acetal resin with a degree of acetalization of 20-40 mol% are also known.
- Also suitable for the production of transparent toner layers on polyester, for example Melinex or Hostaphan film are water-soluble cellulose polymers with non-ionic or ionic ingredients.
- glass-clear polyester films with ink-receiving layers in the composition vinylpyrrolidone, particles of a polyester, a copolymer of a 2-6-C-alkylene oxide, a polyvinyl alcohol and inert particles are known.
- Films are also made from the prior art to remove polyethylene, polypropylene and polycarbonate with a one-sided coating as an ink fixing layer, this layer consisting of emulsions / dispersions of vinyl chloride-vinyl acetate copolymer resin.
- this layer consisting of emulsions / dispersions of vinyl chloride-vinyl acetate copolymer resin.
- colloidal silicon oxide ensures that the finished material is largely non-blocking.
- a disadvantage of the films listed - depending on the field of application - is that although polyester films and nonwovens are in principle suitable as starting materials for the weather-resistant covering of aircraft models, despite the high tensile strength of such materials, there are limits to the covering size and weight-bearing capacity and their use, for example in the production for one-person aircraft, is therefore not possible.
- the materials provided with the listed toner layers are crystal clear to milky-cloudy when viewed and reproduce the copy in black on a transparent and / or milky cloudy background. Due to the transparency of the material, they have little or no advertising effect.
- the object of the present invention is to improve the use properties of heat-activatable, shrinkable, colored films based on polyethylene terephthalate.
- the polymer coating of the film according to the invention is intended firstly to improve the surface quality of the thermosetting colored layer, to increase the tensile strength of the film and to reduce the weight per unit area, and secondly to provide a colored background for the Film with simultaneous one-sided equipment of the Film with pressure sensitive adhesive be opened up new areas of application.
- the film should also be coated in such a way that it can be used in duplication techniques.
- the multilayer material according to the invention has improved usage properties during processing, as well as higher tear resistance and better weather resistance compared to conventional materials.
- the surface of the film is modified ("roughened") by chemical and physical treatment by means of electron bombardment in such a way that the connectivity of the polymer coating to the carrier film is significantly improved in contrast to conventional methods. This is expressed in that the polymer coating is better connected to the film.
- the prerequisite here, however, is that the polymer coating follows the corona treatment directly in terms of time.
- the pressure-sensitive adhesive layer is applied in the known transfer process by using pressure-sensitive adhesives based on polyacrylics, known compositions, which are applied as a solution to silicone paper and, after the solvent has evaporated, are connected to the carrier film under pressure and heat.
- the side of the carrier film facing away from the polymer coating has a transparent reactive layer.
- This layer can be a toner or ink receiving layer, preferably made of vinyl acetate, the toner layer being between 2 and 8 g / m 2 carrier film.
- This measure creates a polymer film with a compact or translucent colored background which, without impairing the text and / or image reproduction quality, serves as an image and print receiving sheet for a copying machine working with normal paper. Films of this type are also particularly suitable for advertising purposes, since they have the homogeneous color distribution already mentioned above within the polymer layer and are also very weather-resistant due to the thermoset properties of the film.
- the agent suitable for avoiding this effect is dispersed in the toner layer.
- agents can, for example, coloidal silicon dioxide or - in the case of water-soluble dispersions - instead up to max. 3% rice starch.
- the reactive layer can be a light-sensitive layer, which opens up further possible uses.
- the film is provided with a metal layer of small thickness, namely ⁇ 1 ⁇ , which preferably consists of aluminum and / or chromium, on the back for the polymer coating.
- a metal layer of small thickness namely ⁇ 1 ⁇ , which preferably consists of aluminum and / or chromium, on the back for the polymer coating.
