[0009] Other and further objects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
Summary of the Invention

[0010] The present invention discloses a method to transfer an image from a support to a substrate comprising the following steps: provide a substrate, provide an image on an image support, apply a layer of epoxy on said substrate and allow said epoxy to cure partially or completely, apply said image on said substrate and preferably remove said image support from said epoxy.

[0011] The present invention allows a user to transfer an image from a support to a wide variety of substrates. In fact, this method may be used on any substrate on which epoxy may be used. For example, it may be ceramic, flooring tiles, mural tiles, porcelain, glass, wood, plastic, cement, stone, leather, minerals, rubber, textiles, concrete, metals, organic fibres, mineral fibres, vegetal fibres, ceramic, board or form composition, glass, cork, acetyl films (rolls), paper, clay, anti-adhesive molds, membranes, UV film, etc.. .Any materials having a 3D texture and from which the epoxy may be removed may act as a an image support. In the particular field of flooring, the substrate may be the subfloor or the membranes that are used for different uses such as acoustic membrane, isolating membrane, anti-crack membrane, etc.. .The main advantage of epoxy is the high File number: 11185-001 Revision: as amended Date: August 19, 2014 resistance to abrasion and water which are the main causes of damage and erosion.
Furthermore, this method allows the transfer of the texture of the image.

[0012] It is to be noted that, in the present document, the term "image"
refers not only to photographs, lithographs and printed material but also to any other composition of pigments and/or elements having a color and/or texture that may be absorbed and/or reproduced on a layer of epoxy. For example, an image may be composed by the elements of the non-limiting following list: dry ink, metallic ink, paint, pigments, rubber, metallic or organic powder, organic (mineral or vegetal) fibres, organic and mineral powders and crystals and other products having phosphorescent, reflective and/or luminescent properties. Finally, the image support does not have to be saturated by the pigments and/or elements.

[0013] The image may come from a wide variety of supports and forms with or without texture, as shown in the following non limiting examples; paper, photograph, newspaper, paperboard, textured paperboard, painting, paint canvas, fabric, leather, mineral, rubber, concrete, metal, organic fibres, wood, tiles, ceramic, board or foam compositions, glass, porcelain, cork, acetate films, clay, anti-adhesive mold, membrane, plastic, UV films. The image support may have protective properties that need a further treatment.
such as a baking or a curing to have the protective properties. The substrate and the elements composing the image are then chosen with an adequate resistance to the temperature of the baking or the curing of the protective layer.

[0014] The layer of epoxy may be applied between two image supports and in this case one of the image supports on which the layer of epoxy is applied acts as a substrate. It is thus possible to have a sheet like piece of epoxy on which both sides have a transferred image and/or texture.

[0015] In one embodiment, the method to transfer the image is applied to flat pattern or none complex geometry. The substrate on which the image will be transferred is coated with epoxy. The thickness of the layer will depend on the desired end result and whether File number: 11185-001 Revision: as amended Date: August 19, 2014 a texture is to be transferred or not. When the layer of epoxy is partially or completely cured, the image support is applied on the layer of epoxy, the image side facing the epoxy. Pressure is preferably applied to the image support to insure proper image and/or texture transfer. This can be achieved with a pressure applied on the image support manually, by a mechanical process, de-bubbling process or any other suitable means.

[0016] In another embodiment, the method may be used for complex geometry objects.
In such an embodiment, the epoxyis allowed to cure partially or completely.
The curing may be endothermic or exothermic as a need to accelerated curing with an external source like heat, microwave or UV light, autoclave, or any other suitable means.
Depending of the desired result and of the material of the image support, the latter may be removed or not. The image support may be left on the layer of epoxy for aesthetical reasons of if the image support has protective properties. The image support may be removed using an appropriate method depending of the image support. It is to be noted that further treatments may be done on the image to change or improve its final appearance properties. For example, a surface layer of epoxy or other material may be added to improve the resistance to abrasion or degradation. A shining technique method appropriated to product can be used to achieve esthetic appearances. Topcoat layer may be translucide, transparent colored for added esthetical goal.

[0017] Typically, the image support may be removed by pulling it. In the case of paper and similar products, such as dissoluble material, minerals, material having fibrous or crystalline properties, or, material made with combinations of fibers or crystalline, organic and minerals composites, water is applied and the surface is manually or mechanically brushed to remove some or all the residual fibres.

[0018] Many forms of epoxy may be used to transfer images and textures, for example, epoxy resins, epoxy foam bonding gels. Acrylic resins may also be used for this application. Furthermore, additives may be added to changes the physical or aesthetical properties. The resins or the foams may be colored and/or translucide.

[0019] Another aspect of the present invention is to allow the use of the image support to become a substrate. From that substrate, the image support may be subsequently removed from epoxy to leave a cavity. Such cavity may be later filled by elements or objects to procure desired characteristics.

[0020] Another aspect of the present invention is the use of dissolvable image supports.
Such image support may bring a shape and texture to the object, either smooth or plane, with an image composition or textured with a textured image composition.
Furthermore, it has the advantage of use of repeatable production of singular pattern obtain from a master cast.

File number: 11185-001 Revision: as amended Date: August 19, 2014 Detailed Description of the Preferred Embodiment

[0027] A novel method to transfer images on a substrate will be described hereinafter.
Although the invention is described in terms of specific illustrative embodiment(s), it is to be understood that the embodiment(s) described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.

[0028] Figure 1 shows a schematic representation of the layers applied on the substrate 110. A thin layer of epoxy 120 is disposed on the substrate 110 and the image support 130 is disposed on the layer of epoxy 120.

[0029] In Figure 2, the method to transfer images on a substrate is illustrated. First, a layer of epoxy 240 is applied on the substrate 210. Then, the image support 250 is disposed on the layer of epoxy 240 following the direction of the arrows. The image side 260 of the image support 250 is placed in contact with the layer of epoxy 240.
Pressure to assure intimate contact is applied as needed.

[0030] The method to transfer a texture is shown in Figure 4. A layer of epoxy 400 is applied on the substrate 410. Then, the image support 420 having a texture is pressed against the layer of epoxy 400. The texture is transferred in the layer of epoxy 430. The surface layer of image support 420 may also comprise the properties of layer 260, as shown in Figure 2. The image support layer 420 may act as the substrate on which a layer of epoxy 400 is applied. As shown in Figure 4c), the epoxy 430 is shown in a state where the image support 420 is removed.

[0031] The flow chart of Figure 3 shows the steps of the present invention.
For the first step 310, prepare a substrate surface, the surface may be any surface on which epoxy will adhere. The next step 330 is to apply a layer of epoxy on the substrate surface or on a mold surface. Indeed, epoxy may be used in a resin form, a foam bonding gel form or any other suitable form for this application. Furthermore, the resin or the foam bonding gel File number: 11185-001 Revision: as amended Date: August 19, 2014 may be translucent or opaque and even colored with the addition of pigments.
When the resin or the foam bonding gel is partially cured or completely cured 350, the image is applied on the substrate surface through the image support 360. The curing of the layer of epoxy may be accelerated by providing proper conditions through an external source. The support may be a paper sheet, a photograph, a painting, a fabric or any other suitable support. Finally, when the epoxy is partially or completely cured, the image support is removed 380. A facultative step 390 is to apply a finishing coat to get a particular effect (brilliance, mate, etc...) or to get a better protection.

[0032] In Figure 5, an image is transferred from an image support 525 to a layer of epoxy 520 which is applied in a cavity 515 of a hockey puck 510. A protective layer may be added to protect the image and the image support itself may be the protective layer.
