Definitions

• the present invention relates to a method for transferring designs and patterns onto the surfaces of various objects.
• patterns There are several different ways in transferring patterns and designs (collectively called “patterns” below) onto surfaces of various objects. Since these transfer methods require predetermined continuous steps to finish, the methods are only suited for mass production which is done by manufacturers who own large scale printing machines.
• the general aim of the present invention is to solve these problems.
• the primary aim of the present invention is to provide a novel transfer method which allows the simple transfer of designs and patterns including letters, numbers, symbols, etc. (called “pattern” or “patterns”) to any desired surfaces, such as floors, walls, vehicles, elevators, ceilings, glass windows, wood, cloth, leather, paper, rubber, plastic, stone, ceramics, metals, concrete, asphalt roadways, etc. even if the surfaces are curved, uneven or have a poor surface smoothness.
• the invention solves the problem by the use of an electrostatic recording paper, and patterns to be transferred onto surfaces are executed on such a paper.
• a pattern is executed on the recording paper by various different ways including printing, color copying, hand drawing and other methods.
• the electrostatic paper with the pattern thereon is pasted on the surface of an object that receives the patterns. Then, the electrostatic paper is peeled off while being wet with a liquid such as water, a solvent, etc., leaving the pattern alone on the surface of the object.
• a transfer paper is prepared by executing a desired pattern on an electrostatic recording paper by way of printing, hand drawing, color copying, etc., and (2) the thus obtained transfer paper with a pattern layer thereon is affixed via a tackifier or adhesive agent on the surface of an object upon which the pattern is to be transferred, and then (3) the electrostatic recording paper is wet by water or another liquid and is peeled off so that only the pattern layer with the pattern thereon remains on the surface of the object.
• the surface of the thus transferred pattern layer is coated with a synthetic resin so that a protective film is formed on the pattern on the object.
• the basic material used in the present invention is a so-called "electrostatic recording paper” made and sold by numerous paper manufacturers, copy machine makers, etc.
• the electrostatic recording paper has a thickness of 30 to 60 microns, and the surface thereof is coated with a substance, such as a conductive powder, etc. which has a property of causing an adhesion of substances that carry an electrostatic charge.
• a transfer paper is first made by executing a desired pattern on the electrostatic recording paper.
• the pattern is printed, hand drawn, color copied, etc. with the use of oil-based pigments (and not water-based dyes), then the pattern is executed or applied directly to the electrostatic recording paper without performing any pretreatment.
• the transfer paper be formed by printing, hand drawing, color copying or ther methods after pretreatment.
• the pretreatment is performed by coating the electrostatic recording paper with gelatin, polyvinyl alcohol or a calcium carbonate dispersion liquid, and then the pattern is executed thereon.
• the electrostatic recording paper should be coated beforehand with a transparent binder. After this process, the pattern is applied by color copying on the surface of such a transparent coating film to produce a transfer paper.
• the tackifier or adhesive agent used in the present invention to affix the transfer paper to the surface of an object is selected in accordance with the material properties of the object and with the material properties of the pattern layer which is to be transferred. In other words, a material which causes tacky adhesion or bonding of both (the object and the transfer paper) without harming the material properties of them should be selected.
• a solvent type adhesive agent for metals is most suitable.
• a two-part epoxy adhesive or a two-part urethane adhesive as the adhesive agent.
• the tackifiers and adhesive agent which are used in the present invention can be solvent type adhesive agent or tackifiers, instant adhesive agents, emulsion type adhesive agents or tackifiers, and water-soluble adhesive agents or tackifiers.
• the tackifier or adhesive agent used in the present invention is selected, via trial applications, etc., in accordance with the material properties of the object and the pattern layer which is applied onto the surface of an object.
• the tackifier or adhesive agent selected pursuant to the above criteria is applied on the surface of an object.
• a solvent type adhesive agent may be applied on the surface of the pattern of the transfer paper instead of the object's surface.
• the object is a hard material, a two-part urethane adhesive, a two-part epoxy adhesive or an acrylic type adhesive is desirable as the adhesive agent.
• the object is a material that is weak in bonding, such as vinyl rubber, glass, iron, etc., it is desirable to first apply a binder to the object and then to use a tackifier or adhesive agent of a solvent type which can retain tackiness even after drying.
• a gold, silver or white leaf is pasted to the pattern surface of the transfer paper.
• respective colors such as red, white, etc. can be applied on the transfer paper.
• a tackifier is applied on such a color and dried, and then with the tackiness still remaining, a mold release paper is pasted to the pattern surface. The mold release paper is peeled off and then the transfer paper is affixed to the object at the site of transfer of the pattern.
• the object is a soft material, such as paper, leather, cloth, synthetic leather, etc.
• a single-liquid type acrylic or urethane water-soluble adhesive agent or tackifier is used because such an agent does not cause a loss of the softness.
• a two-part epoxy adhesive, a two-part urethane adhesive or a two-part acrylic adhesive is applied on the surface of the object to smooth the surface.
• the tackifier or adhesive agent is applied, and then soapy water is applied thereon.
• the transfer paper can move freely when it is pasted to the surface of an object, thus allowing an easy affixing to a desired position.
• the affixing is completed when the soapy water is dried, and the transfer process can go to the next step.
• the transfer paper be applied via an instant adhesive agent by letting the dry be delayed for two to ten minutes so that the air and liquid are removed between the object and the transfer paper before the instant adhesive agent is completely dried.
• the transfer paper After the pattern on the transfer paper has been pasted on the surface of the object, the transfer paper is wet with water or some other liquid and then peeled away. In other words, the transfer paper is wet with water, etc., on its back surface (i. e., the surface with no pattern) and is peeled off so that the pattern layer with the pattern thereon only remains as a transferred pattern on the surface of the object.
• a synthetic resin is applied on the surface of the pattern layer so that a protective film is formed.
• the film can improve the durability of the transferred pattern.
• the protective film is a lipophilic synthetic resin coating layer. If the pattern layer is an oil-based layer, it is desirable to use a hydrophilic synthetic resin coating layer to form the protective film.
• the pattern is obtained from a water-based ink, a solvent type urethane resin, acrylic resin, fluororesin, etc. is used to form the protective film.
• a solvent type urethane resin, acrylic resin, fluororesin, etc. is used to form the protective film.
• discoloration is prevented and wear resistance can be increased.
• wear resistance can be increased.
• the durability of the pattern is improved.
• the protective film is formed by changing the synthetic resin solvent in accordance with the materials such as pigments, toners, coloring materials (e.g. oil paints, water colors), and color copy type materials for the patterns to be transferred so that the durability is improved, the pattern is reinforced, discoloration is prevented, and a beautiful finish is obtained.
• materials such as pigments, toners, coloring materials (e.g. oil paints, water colors), and color copy type materials for the patterns to be transferred so that the durability is improved, the pattern is reinforced, discoloration is prevented, and a beautiful finish is obtained.
• the pattern is transferred to a soft object, it is preferable to use a soft urethane resin or acrylic resin so that the "feeling" or texture of such a soft material is not lost.
• ultraviolet absorbing agents When more effective prevention of discoloration is desired, ultraviolet absorbing agents, fluororesins, etc. are used.
• patterns can be transferred to all types of objects.
• any desired designs and patterns can be transferred to the inside surfaces of completed buildings, to the inside surfaces of elevators and vehicles, to all types of materials in all types of locations, outside walls, fences, roadways, ceramic materials, glass windows, wood, leather, cloth, paper, rubber, concrete, plastics, metals, stone, etc., and also to spherical surfaces and curved surfaces.
• the method of the present invention is simple and can be used to hide seams and joints.
• multiple transfer can be possible by transferring one design or pattern onto another.
• a figure of a soccer player in a game was formed on an electrostatic recording paper of 50 microns thickness (manufactured by Fuji Xerox K.K.) using a pigment type color copier. No pretreatment was performed thereon. Thus, a 300 mm x 500 mm transfer paper with the succor player pattern layer thereon was obtained.
• the object or the transfer-receiving material was a concrete block of the same size (300 mm x 500 mm) as the transfer paper.
• the concrete block was coated at a rate of 20 g/m2 with a concrete sealer (manufactured by Nippon Paint K.K.) which has a 50 % solid content.
• the concrete sealer was used as an alkali-blocking agent.
• casein of aqueous solution with 35 % solid content (manufactured by Kyowa Kasei K.K.) was applied twice on the concrete sealer by a brush at a rate of approximately 60 g/m2 (when wet) as an adhesive agent.
• the casein was dried by a hot air draft, and the transfer paper was pasted on this concrete block. When pasted, the pattern surface of the transfer paper is brought so as to be in contact with the surface of the concrete block.
• the transfer paper was impregnated with water.
• the water is applied on the surface which is the opposite side from the pattern surface so as to wet it, and then the transfer paper was peeled off.
• the pattern on the pattern layer representing the soccer player in a game was thus transferred onto the surface of the concrete block.
• the surface of the pattern of the soccer player was then coated at a rate of 30 g/m2 (when wet) with a water-based polyurethane resin preparation containing a solid content of 32 % ("Neodeluxe UW" manufactured by Otani Toryo K.K.), and the coating was dried, thus forming a protective film.
• the concrete block had small indentations and projections on its surface, but they did not affect the transfer process at all.
• Embodiment 2 The same electrostatic recording paper used in Embodiment 1 was used. In this Embodiment 2, a pretreatment was performed on the recording paper.
