Definitions

  • the present invention relates to a printable substrate for cold and dry transfer of decorations in a rapid way, permanently, and without the use of water on new surfaces to be decorated.
  • the invention also regards the process for the production of said substrate, as well as its use in the decoration of surfaces, both glossy and opaque ones.
  • the sector of the present invention regards transferable decorations or decalcomanias printed in a small number of examples or even in a single example using especially plotters for digital printing, this not being possible with products that are pre-printed and pre-adhesivized industrially.
  • the product once printed, can be used for decorating both glossy and opaque surfaces, such as plastic, metal, and wood, but, given the characteristics of elasticity and opacity, it is particularly suitable for opaque surfaces that may even be very irregular, such as masonry walls or the like.
  • the substrate of the present invention enables fast, cold, permanent and dry transfer, i.e., without the use of water, of artistic reproductions and/or of printed decorations even of large dimension that look very similar to decorations made by hand.
  • This product is likewise suited to being decorated by hand in laboratory before applying, enabling transfer of the painting onto the surfaces in question in a very short time and thus avoiding for the possible customers all the inconvenience deriving from a decoration painted by hand directly on the wall to be decorated.
  • NWF non-woven fabric
  • the NWF is glued on the printed side onto the material to be decorated, using synthetic resins in aqueous dispersion.
  • the NWF which is by now unusable after transfer, is then removed upon soaking with water, and the transferred decorations are dried with air for some hours to enable consolidation of the water glue.
  • the present invention envisages a substrate that can be decorated by hand or printed with a quality of photographic printing higher than electrostatic printing, since, in addition to the traditional printing techniques, it can be printed also at very high resolution with plotters for digital printing with solvent, ecosolvent, and UV inks; all the decorations thus printed on said substrate can undergo dry and cold transfer onto the surfaces to be decorated.
  • this substrate can be marketed for being subsequently personalized manually or with digital plotters according to the desires of the end customer, even with decorations of large dimensions for commercial activities and ones made up of a number of parts that can be easily assembled together, this being something that cannot be obtained with other industrially pre-printed and pre-adhesivized products .
  • the base substrate of the present invention can be paper, textile (for example, cloth paper or non-woven fabric) or plastic (for example, a polyester film) , spread with suitable synthetic resins that can be decorated on the surface. Once the decorated layer has been glued and transferred onto the new surface, the base substrate can be lifted off and eliminated with a dry and cold process immediately afterwards by exerting a slight manual pulling action and without any need for the soaking operation.
  • a further advantage of the present invention as compared to the known techniques is that it is no longer necessary to carry out a final protective painting on the decoration, since, in the transfer, the colour is already protected by the layer of transparent resins that previously served as base for printing.
  • a substrate that can have different dimensions according to the production and application requirements and that consists of: a first layer (A) chosen from among paper, textile, and plastic material; a second, very thin, layer (B) of water-repellent transfer resin, preferably a silicone resin, possibly with the addition of approximately 40-50% of colloidal silica, which is spread directly over said first layer
  • the first layer (A) of material according to the present invention must be flexible to so as to be workable, printable and applicable easily on surfaces that may even be very irregular during transfer of the decorations.
  • the second layer (B) of water-repellent transfer resin which enables temporary adherence of the last third layer (C) that serves as base for printing, preventing detachment of the decorations printed or decorated thereon up to the moment of their transfer.
  • the colloidal silica or similar opacifiers possibly used by adding them to the water-repellent resin, have the sole purpose of rendering opaque (i.e., non-glossy) this second layer and especially the third layer of transparent paint subsequently spread, which serves as base for printing, which in this manner is opaque even without opacifier, in such a way that the decorations, once printed. and transferred together with the layer of paint (C) , can be adapt perfectly to the opaque surfaces of the masonry walls.
  • the third layer (C) if made up of polyurethane resin possibly mixed with other resins, enables, according to the percentage of polyurethane used, an excellent malleability of the paint, which in this way is suitable also for very irregular surfaces.
  • the acrylic or vinylic resins when used in the mixture, enable the paint to have a limited elasticity of return, preventing, that is, after a possible pulling action exerted on very irregular surfaces, a return thereof into the starting position, a factor that is prejudicial in the possible joining of very large decorations made up of a number of parts, since a small white line would become visible as the paint shrinks.
  • This layer of transparent paint by adhering to the surfaces that may even be very irregular, creates a particularly flexible protective film on the layer of colour once it has been transferred and renders any further protective painting needless .
  • Water-repellent transfer resins which are widely used in the industrial sector to guarantee temporary adhesion of the material that has been spread, normally range from “easy” release up to "very tight” release.
  • water-repellent transfer resins are used that have a release control that can preferably range from approximately CR40 to approximately CR60. Said value is chosen also on the basis of the characteristics of stickiness of the paint of the third layer (C) spread over the water-repellent substrate (B) and the possible additives used in the resins (opacifiers, catalyzer, surfactants, etc.).
  • Said water-repellent resin (B) and the resins constituting the paint of the third layer (C) of the present invention may be water-based or solvent-based resins, but ones insoluble in water once they are dry.
  • the substrate, on the surface of the layer (C) can be decorated manually or printed employing any technology, especially digital technology, using inks or colours that are insoluble in water once dry.
  • Forming a further subject of the present invention is a process for the production of printable substrates for decorations that can be transferred onto surfaces as has been described previously, characterized by the following industrial operations: a) the first layer of material (A) chosen from among paper, textile, and plastic, is spread with a second layer (B) of water-repellent transfer resin; and b) a further third layer (C) of transparent acrylic, vinylic, or polyurethane paint, even made up of a number of coats according to the processing technique is then spread over the water-repellent resin
  • annexed hereto is a drawing illustrating a lateral section of the substrate constituted by a first layer (A) of paper, textile, or plastic material, spread with a second layer (B) of water-repellent transfer resin and then with a third layer (C) of transparent synthetic paint .
  • a suitable pressure-sensitive self-adhesive glue preferably an acrylic, water-based, or solvent-based glue, that is no longer soluble in water once dry, which is spread either directly on the decoration or on the surface to be decorated.
  • the glue is spread manually with a paintbrush or a roller directly on the printed side (C) of the substrate. After approximately thirty minutes, the adhesivized printed surface, once it has dried and become very sticky, is protected with anti-adherent siliconed paper.
  • the printed substrate is positioned on the side protected with siliconed paper onto the surface to be decorated, stopping it at one end all along the side with adhesive tape. Then, .the substrate is rolled up as far as the point where it is blocked by the adhesive tape and, as the underlying protective siliconed paper is gradually removed, the adhesivized decorations are made to adhere by pressing them on the wall with a roller or a brush beaten on the whole surface.
  • the first layer (A) of the substrate i.e., the paper, textile, or plastic material, now overlying, may be immediately lifted, starting from one corner, and detached by exerting a slight pulling action so as to overcome the last resistance that still keeps it attached to the decoration that has by now been transferred and is protected by the now overlying layer of transparent paint (C) .
  • the self-adhesive glue for transfer the surface to be decorated is framed by masking it with adhesive tape to avoid dirtying it on the outside.
  • the glue is spread directly inside the framed surface, using a paintbrush or roller.
  • the self- adhesive glue once it has dried and become very sticky, is protected with anti-adherent siliconed paper.
  • the substrate is positioned on the printed side on the framed surface, fixing it all along one side with adhesive tape.
  • the protective siliconed paper is removed gradually from the underlying adhesivized surface, causing adhesion of the decorated layer, as it is unrolled,- by pressing it with a roller or a brush that is beaten all over its surface.
  • the first layer (A) of the substrate i.e., the now overlying paper, textile, or plastic material
  • the first layer (A) of the substrate i.e., the now overlying paper, textile, or plastic material
  • the first layer (C) of transparent paint (C) may be immediately lifted, starting from one corner, and detached by exerting a slight pulling action so as to overcome the last resistance that still keeps it attached to the decoration, which has by now been transferred and is protected by the now overlying layer of transparent paint (C) .
