Definitions

  • the invention relates to a hot transfer film for decorating substrate surfaces, which comprises a carrier film and a decorative layer arrangement releasably connected thereto, and a method for the production thereof.
  • Such decorative films are widely used for decorative surface coating.
  • the free, provided with an adhesive layer surface of the decorative layer assembly is connected under the influence of heat and pressure with the substrate surface to be decorated, and then the carrier film, which is connected via a release or release layer to the decorative layer arrangement deducted.
  • the carrier film which consists of a polymer film carrier material with a release or release material, for example wax, coated.
  • the decorative layer arrangement adjoining the separating layer comprises a transparent protective lacquer layer, a non-continuous decorative lacquer layer, for example in the form of a grain, printed on the protective lacquer layer, a continuous lacquer layer and an adhesive layer consisting of a heat-activatable adhesive.
  • the known hot transfer films which are characterized by the use of solvents and solvent inks by a slight drying, are disadvantageous in that the coating formed on a substrate in a plurality of separate functional layers are made of a variety of thermoplastic resins and using appropriate solvents. Since each layer is structured differently, the layers are not miscible with each other. For each layer a special color is required, matched to the particular binder and thus to different solvent combinations. The manufacturing process for the paint is therefore correspondingly complex and not very flexible.
  • the invention has for its object to develop a functioning on flat and profiled substrates hot transfer film, which nevertheless meets the requirements placed on such a film in terms of processing and use properties requirements with a reduced number of layers and with reduced Manufacturing and equipment costs can be produced, and to provide a method for their preparation.
  • the basic idea of the invention consists in the formation of the decor layer arrangement of the hot transfer film based on a water-based binder in the form of acrylate or vinyl acetate dispersions consisting of a basecoat film, a decorative layer and a transfer layer into which the same waterborne colorant body in one or more layers is incorporated in the form of binder-free pigment concentrates.
  • the hot transfer film formed in this way does not require a separating layer between the basecoat film and the carrier film, since even the acrylate-based basecoat film ensures detachment of the carrier film after bonding of the hot transfer film to the substrate.
  • the acrylate or vinyl acetate binder acts in the transfer layer after heating on the substrate to be coated as a thermoplastic adhesive, so that can be dispensed with the formation of an adhesive layer.
  • the hot transfer film can thus consist of only two or three layers connected to the carrier film, namely a basecoat film and a transfer layer and optionally the decorative paint layer formed between them.
  • the so-formed hot transfer film is characterized by low manufacturing and material costs.
  • the production of the hot transfer film takes place - in a simple manner - on conventional printing machines.
  • the application of the layers on the carrier film by means of engraved printing rollers, with doctor blades or by pouring.
  • the colorless component corresponding to each layer to be applied comprises a dispersion of the acrylate or vinyl acetate binder and water and an additive of additives acting as defoamer and leveling agent.
  • an anti-scratching agent may be provided as a mechanical surface protection.
  • the dispersions contain a colorant provided for the decorative layer and the transfer layer and optionally also for the basecoat layer, ie one and the same water-based pigment paste or pigment concentrate in the desired amount and color as a decoration or to cover the substrate to be coated. Since all acrylate or vinyl acetate dispersions are water-based, their mixing with the likewise water-based pigment concentrates is readily possible. The provision of the application means required for the individual layers, since only a single diluent, namely water, and consequently a multivalent water-based pigment paste is used, very simple. For the preparation of the pigment pastes or concentrates, all known organic and inorganic pigments can be used.
  • the solids content of the acrylate or vinyl acetate binder in the dispersion is between 35 and 65%, while the proportion of additives for stabilizing the dispersion, for defoaming and as Lackverlaufsstoff can be 0.1% and 10%.
  • the manufacturing process is compared to the known methods simple and inexpensive, as for the coating conventional printing presses can be used and can be dispensed with exhaust systems for flammable and toxic gases.
  • the low number of layers, in particular the elimination of the release or release layer, and the use of one and the same water-based binder and water-based ink carrier also have a cost-effective effect on the production process and the subsequently produced hot transfer film.
  • Acrylate homopolymers or copolymers for example styrene-acrylate copolymers, methacrylate acrylate copolymers, butyl acrylate-methyl methacrylate copolymers, methyl acrylate homopolymers are used as the acrylate binder.
  • the vinyl acetate binder e.g. Ethylene-vinyl acetate copolymers or copolymers used between vinyl acetate and other conventional comonomers.
  • the polymeric acrylate dispersions and vinyl acetate dispersions may have partially cross-linkable end groups in the basecoat and may be treated with specific curing agents, such as e.g. be crosslinked on the basis of water-dispersible isocyanates, aziridines and epoxides.
  • aqueous wax dispersions or special organic low molecular weight, oligomeric and polymeric organic-substituted or inorganic silicon compounds are used.
  • the basecoat film can also already be dyed with a binder-free colorant, a pigment paste or pigment concentrate.
  • a defined structure can be printed directly on the carrier film, which contains a water-displacing hydrophobic pigment-like compound, for example calcium stearate, and thereby a displacement the aqueous acrylate binder and thus causes the formation of a so-called pore structure.
  • a water-displacing hydrophobic pigment-like compound for example calcium stearate
  • the decorative layer (or color layer) printed thereon after application of the basecoat layer comprises a waterborne acrylate and / or vinyl acetate homo- or copolymer binder as colorless component or blend colored with a binderless color carrier, pigment paste or pigment concentrate.
  • the transfer layer is also made of water-based acrylate and / or vinyl acetate binder, which can be mixed with the water-based pigment pastes or pigment concentrates used in the other two layers, preferably an organic pigment-based capping ink, e.g. Titanium oxide and / or iron oxide, may be colored.
  • an organic pigment-based capping ink e.g. Titanium oxide and / or iron oxide
  • the polymer particles of the water-based binder melt and form a closed paint film, in intimate adhesive connection with the Substrate surface is. A separate adhesive layer is therefore not required.
  • the drying of the water-based mixtures or layers applied to the carrier film takes place by convection drying with circulating air and heat.
  • the hot transfer foil 1 comprises a carrier foil 2 on which a base lacquer layer 3, a decorative layer 4 and a transfer layer 5 are located in the stated order.
  • the basecoat layer 3 is used in an amount of 2 to 10 g / m 2 dry weight
  • the decorative layer 4 is applied in an amount of 0.05 to 2 g / m 2 dry weight
  • the transfer layer 5 is applied in an amount of 15 to 40 g / m 2 dry weight
  • the base sheet 2 is made of a resin having a high heat resistance of about 140 to 150 ° C, and is a polyester film in the present embodiment.
  • the carrier film 2 may also consist of PET, polyamide or similar heat-resistant plastics.
  • the basecoat film 3 contains an acrylate binder, which is applied as a dispersion having a water content of 35 to 65% and with the addition of a defoamer and an anti-scratching agent and a leveling agent to achieve a smooth surface on the carrier film 2.
  • the basecoat layer 3 of water-based acrylate binder applied directly to the carrier film 2 simultaneously acts as a release layer, which later makes it possible to easily remove the carrier film.
  • the subsequent decorative layer 4 comprises, like the basecoat film 3, a binder of an acrylate or vinyl acetate dispersion applied as a dispersion with a water content of likewise 35 to 65%, the dispersions still being a water-based, ie binder-free Color carrier, namely pigment pastes or pigment concentrates, as well as additives in the form of a defoamer, a leveling agent and a dispersing aid.
  • a waste that is a serving for whitening colorless paint in the form of a dispersion in water - with the addition of leveling and dispersing agent and defoamers - present acrylate binder applied.
  • the transfer layer 5 (or primer layer) consisting of a thermoplastic acrylate binder water dispersion and a vinyl acetate binder water dispersion with defoaming and dispersing additives is applied.
  • the transfer layer 5 further contains a water-based color carrier with high hiding power in the form of a binder-free pigment paste, e.g. of titanium oxide and / or iron oxide or other opaque organic or inorganic pigments.
  • the thermoplastic binder here has at the same time an adhesive function in that it softens well above room temperature, so that after application to a substrate to be coated under pressure and heat, a firm connection between the transfer layer 5 and the substrate is created, without training additional adhesive layer.
  • aqueous acrylate dispersions with the respective blended water-based pigment pastes or pigment concentrates and additives for the basecoat film 3, the decorative layer 4 and the transfer layer 5 in the present embodiment is carried out continuously in a roller application process with engraved printing rollers with intermediate drying of the individual layers easily done with conventional printing machines.
  • Each layer essentially comprises water-based acrylate or
  • Vinyl acetate binder and is in each case miscible with the same, that is binder-free and water-based pigment concentrate and dyeable. Since water-based dispersions are applied in all cases, neither toxic nor flammable solvents can be released, so elaborate exhaust systems are not required. The manufacturing and equipment costs and the cost of the coating materials used is thus low, especially since the usual separation or release layer is not necessary and also the adhesive layer can be omitted.
