DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0017] Reference will now be made in detail to presently preferred embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that modifications and variations can be made in the present invention without departing from the scope or spirit thereof. For instance, features illustrated or described as part of one embodiment may be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0018] Embodiments of the present invention include methods for the application of labels onto substrates of various shapes and sizes. Common to the embodiments of the invention is the absence of a paper or other material backing associated with the label and its application to the substrates. In the embodiments of the present invention, due to the absence of such non-transferable component normally associated with a label, there is a reduction in the amount of waste associated with the application processes. In addition, utilizing the methods of the present invention, the application of labels to substrates of various sizes and shapes, including three-dimensional substrates, may be completed more effectively as the components of the present invention may contour to the dimensions of substrate, as more fully discussed below.

[0019] Figures 1 and 2 illustrate a first embodiment of the present invention, as a label may be applied to a desired substrate without the use of a backing material. As common with the first through fourth embodiments described, the present invention utilizes a transfer mechanism that the components of the label are first applied to and then is used to transfer those components onto the desired substrate. As shown in Figures 1 and 2, a transfer mechanism 101 is deposited (Step 111) with an ink layer 102 and then a binding layer 103 is deposited (Step 112) on top of ink layer 102. Ink layer 102 and/or binding layer 103 are then dried and/or cured (Step 113) while attached to transfer mechanism 101, and ink layer 102 and binding layer 103 are then applied (Step 114) to a substrate 104 as the adhesive of binding layer 103 makes contact with substrate 104. Transfer mechanism 101 is then returned to its starting position such that the process may be repeated (Step 115).

[0020] As indicated above, transfer mechanism 101 of the present invention is utilized to house the components of the label (i.e., the ink layer and binding layer and possible other components, as discussed further below) prior to the components' application to the particular substrate. Advantageously, the transfer mechanism may be utilized again and again thereby reducing the amount of waste typically associated with such methods.

[0021] To meet the requirements of such methods, transfer mechanism 101 may be a diaphragm constructed on a moving conveyer belt or in a sheet feed system to aid in the process of the application of the necessary label components onto the substrate and then to repeat to process. In some embodiments, the conveyer belt may be continuously moving or may utilize a batch-movement process, or a semi-batch movement process, depending on the specifications of the user.

[0022] Transfer mechanism 101 may be constructed of any material or materials that allow for the various label components to be transferred on and off transfer mechanism 101 and allow for transfer mechanism 101 to maintain its shape during the application of the label components but further allow flexibility to conform to the shape of the substrate. For example, if a diaphragm is used for the construction of transfer mechanism 101, it may include a textured or matte surface to increase the ease of releasibility of the label components to the substrate. In addition, in embodiments where a diaphragm is utilized, suitable materials for the construction of the belt that provide enhanced release qualities as well as the desired flexibility may include silicone, fluorinated polymers, or low surface energy polymers including polyamide, Teflon*, polyolefin, and others. Such materials may be utilized to construct the entirety of the diaphragm or may serve as coatings on the diaphragm depending on the user's specifications. Examples of suitable silicone coated release materials include, D2 CL PET 7300A/7350A, Grade 27320 and 2SLKN and 5.0 MT PET 4400/4400 Grade 26967 from Loparex LLC in Iowa City, IA. In addition, suitable polymer examples include, acrylic-based coatings, such as R130W from Mayzo, Inc. in Suwanee, GA and polypropylene based coatings, such as HFM sheets from Avery Dennison NTP in Pasadena, CA.

[0023] To ensure the proper releasablity of the label components from transfer mechanism 101, the surface energy of transfer mechanism 101 on the side that makes contact with the label components may be between about 20 mN/m and about 40 mN/m. In some embodiments, including those where silicone is utilized in the construction of transfer mechanism 101, additional items, including corona treatment or flame treatment, may be added to transfer mechanism 101 to ensure the proper surface energy.

[0024] Ink layer 102 utilized in the methods of the present invention may include ink or graphics, and may be a mono-colored or multi-colored ink layer depending on the printed message and/or the intended pictorial design. Such designs for use in connection with the present methods include serial numbers, bar codes, trademarks, etc.

[0025] The present methods may utilize a variety of commercially available inks for use in ink layer 102 including UV-curable, latex, water-based, nonpolar, solvent-based, pigments, dyes, solvent-based with polar functionality, Eco-solvent, hot-solvent, solventless, 100% solid and others. Examples of these inks include Sun Sheen (a product of Sun Chemical, Inc. of Santa Fe Springs, CA identified as an alcohol dilutable polyamide ink), Suntex MP (a product of Sun Chemical, Inc. identified as a solvent-based ink formulated for surface printing acrylic coated substrates, PVDC coated substrates and polyolefin films), X-Cel (a product of Water Ink Technologies, Inc. of Lincolnton, NC identified as a water-based film ink for printing film substrates), Uvilith AR-109 Rubine Red (a product of Daw Ink, Inc. of Commerce, CA identified as a UV ink) and CLA91598F (a product of Sun Chemical, Inc. identified as a multibond black solvent-based ink).

[0026] Ink layer 102 may range, in some embodiments, from about 0.5 to about 10 microns. In further embodiments, the thickness of ink layer 102 may range from about 1 to about 5 microns, and in other embodiments, the thickness of ink layer 102 may be about 3 microns.

[0027] The application of ink layer 102 to transfer mechanism 101 may be accomplished by various methods known in the art, including inkjet printing, screen printing, or coating. In one embodiment of the invention, the ink layer may be deposited through raster graphics or bitmap imaging, which is sometimes referred to in the printing and prepress industries as contone or contone printing. In some embodiments where inkjet printing is used, a thermal inkjet printer or piezo inkjet printer may be utilized to apply ink layer 102 to transfer mechanism 101. In such embodiments, the ink of ink layer 102 utilized in the method should be of a suitable viscosity when passing through the printhead of such printers to ensure an accurate and durable image. For example, in such embodiments, thermal inks may include a viscosity of between about 3 and about 5 mPa/s at 25 °C, while piezo inkjet fluids may include a viscosity in the range of about 1 to about 30 mPa/s at 25 °C.

[0028] Binding layer 103 may be constructed of inkjettable adhesives to meet the demands of the method utilized. For example, binding layer 103 may be constructed of monomers, including those of acrylic, epoxy, silicone, vinyl, and olefinic based chemistries. In some embodiments, oligomers or short chain polymers may be utilized in connection with binding layer 103. Short chain polymers that may be beneficial in connection with binding layer 103 refers to polymers where number average molecular weight (Mn) is less than the entanglement molecular weight (Me) for the respective monomeric systems. In addition, to allow such materials to consistently jet through an inkjet nozzle, the materials utilized as binding layer 103 may include a viscosity range between about 5 to about 50 cps..

[0029] In embodiments of the invention where inkjettable adhesives are utilized in connection with binding layer 103, such adhesives may be prepared using any known methods in the art including, emulsion, solvent or solvent-less polymerization techniques, where such inkjettable adhesives may be processed using a solvent, water or a heated nozzle. The user's specifications may dictate the necessary methods utilized for such preparation and processing.

[0030] In some embodiments, the inkjettable adhesives utilized in connection with binding layer 103 may be based on a two-component adhesive system where a first component is jetted through a first nozzle and a crosslinking or curing agent (second component) is jetted through a second nozzle onto the first component. In such embodiments, the viscosity of both components may be maintained at a level to ensure adequate room temperature mixing through diffusion. Suitable first and second component pairs include epoxy oligomers & resins and amine oligomers; epoxy oligomers & resins and acid catalysts; epoxy oligomers and basic catalysts; and oligomers with isocyante functional groups and alchohols, catalysts, or moisture.

[0031] In additional embodiments of the present invention utilizing the two component adhesive, one component of the two components may be coated/printed/fabricated onto the desired surface/media using additional non-jettable technique, including gravure printing, screen printing, casting, spin coating, die-coating etc. In further embodiments of the invention that utilize the two component adhesive, one of the two components may be situated in ink layer 102 to provide the same effect.

[0032] In addition to those adhesives mentioned above, pressure sensitive adhesives (PSA) may be utilized in connection with binding layer 103. PSAs are a class of adhesives characterized by low Tg and may be applied to a given surface at room temperature with the application of a small amount of pressure. Pressure sensitive adhesives are tacky at room temperature and are known to adhere to a wide variety of high and low energy surfaces.

[0033] Suitable PSAs that may be used in connection with binding layer 103 include monomers, for example, 2-Ethylhexyl acrylate, Butyl acrylate that are copolymerized with certain polar monomers including acrylic acid, N-vinyl pyrrolidone or 2- Hydroxy ethyl acrylate. The polymer may then be further crosslinked using known crosslinkers and an energy source to yield a desired balance of tack and shear properties.

[0034] In some embodiments, the molecular weight of the polymer utilized may be in excess of ten times the entanglement molecular weight to allow sufficient chain interactions that allow for proper viscoelastic properties of such polymers. In some embodiments, oligomers or short chain polymers that may be used in connection with a PSA of the present invention may be assembled into a polymer of sufficiently high molecular weight using a self assembly process. Such process may be completed by attaching hydrogen bonding moieties to the oligomeric chains. Suitable hydrogen bonding moieties include vinyl pyrrolidone and acrylic acid, amine functionalized chains and acrylic acid, and other hydrogen bond donors and hydrogen bond acceptors. In further embodiments, hydrogen bonding solvents such as methanol, ethanol or tetrahydrofuran may be utilized. In addition, the combination when processed at a temperature above 75°C, such hydrogen bonds will cease to exist leading to a lower viscosity and once jetted, the chains will assemble into a higher molecular weight polymer, suitable for use in the present invention, due to the aid of hydrogen bonding.

[0035] As described in prior embodiments a desired two or more component adhesive could also be realized by incorporating one of the components onto the surface or media to be printed (jetted) on. As an example, an acid activated system can be achieved either by incorporating the acid sensitive polymer in the media and catalyst in the jettable pack or vice-a-versa to have the same end-effect. Examples of media and surfaces may include glass, paper, PET, PE, Aluminum etc. Additionally, one component of the two component system may be coated/printed/fabricated onto the desired surface/media using additional non-jettable technique. Examples of such techniques would include gravure printing, screen printing, casting, spin coating, die-coating etc.

[0036] In some embodiments, the adhesives utilized in binding layer 103 may include additives to provide enhanced properties. For example, in some embodiments, additives comprising wetting agents, surfactants, inorganic fillers, colorants, viscosity modifiers, optical brighteners and/or others may be added. The user's specifications will dictate the necessary components utilized.

[0037] As discussed above, the present method may further utilize a drying and/or curing step for any or all of the label component layers. Any such methods known in the art may be utilized to complete the drying and/or curing step depending on the particular materials utilized for ink layer 102 and binding layer 103. For example, if the ink utilized for ink layer 102 is UV-curable, then a UV curing process would be utilized in the curing step. In some embodiments, if both drying and curing is utilized, drying through heating may be completed first and then curing may be completed through any known curing process, including heating or radiation (IR/UV), where such radiation curing may involve using a free radical photoinitiator, photo-acid based photcatalytic or a combination curing pack.

[0038] Figures 3 and 4 illustrate a second embodiment of the present invention, where a printable release layer is utilized. The printable release layer, depending on the embodiment, may act as a release or a protective layer as more fully explained below. In the second embodiment of the present invention, transfer mechanism 501 is deposited (Step 511) with a printable release layer 502, which acts to aid in the release of the other label components from transfer mechanism 501. Following the addition of printable release layer 502, an ink layer 503 is deposited (Step 512) onto printable release layer 502. A binding layer 504 is then applied (Step 513) to ink layer 503. The layers 502, 503, and 504 may then be dried and/or cured (Step 514) as necessary. Following curing, ink layer 503 and binding layer 504 are then transferred (Step 515) to substrate 505, while printable release layer 502 remains on transfer mechanism 501 as it provides qualities to release layers 503 and 504. In such embodiments, prior to the repeat of the process, transfer mechanism 501 may be cleaned (Step 516) with a suitable material as discussed below. Following the cleaning of transfer mechanism 501, the process may be repeated (Step 517). In such embodiments of the present invention, depending on the particular item utilized as printable release layer 502, an initial deposit of printable release layer 502 may only be necessary at the outset, whereas in other embodiments, printable release layer 502 may be applied each time.

[0039] Transfer mechanism 501, ink layer 503, and binding layer 504, of the second embodiment may be the same as those described above with respect to the first embodiment.

[0040] As indicated above, printable release layer 502 of the second embodiment acts as a release material to aid in the transfer of ink layer 503 and binding layer 504 from transfer mechanism 501 to substrate 505. Accordingly, printable release layer 502 may be constructed of materials that provide such releasability, similar to those described with respect to transfer mechanism 101 in the first embodiment.

[0041] When a printable release layer is present, it may have a single layer or a multilayered structure. The thickness of the printable release layer may be in the range of about 12.5 to about 125 microns, and in one embodiment from about 25 to about 75 microns. Examples of printable release layers that may be used in connection with the present invention are described in U.S. Pat. No. 6,106,982, the entirety of which is incorporated by reference.

[0042] Printable release layer 502 may comprise polyolefins, thermoplastic polymers of ethylene and propylene, polyesters, polyurethanes, polyacryls, polymethacryls, epoxy, vinyl acetate homopolymers, co- or terpolymers, ionomers, antioxidants, inorganic colloidal silica or alumina binder, and mixtures thereof. To ensure the proper releasablity of ink layer 503 and binding layer 504 from printable release layer 502, the surface energy of printable release layer that makes contact with ink layer 503 may be between about 20 mN/m and about 35 mN/m. In some embodiments, including those where silicone is utilized in the construction of printable release layer 502, additional items, including corona treatment or flame treatment, may be added to printable release layer 502 to ensure the proper surface energy.

[0043] As indicated above, following the transfer of ink layer 503 and binding layer 504 onto substrate 505, transfer mechanism 501 is cleaned. Such cleaning process may remove excess ink and/or adhesive that remains on transfer mechanism 501 following the transfer to the substrate. The cleaning process may be necessary to ensure that a new print layer that is deposited during the present method is not affected by components that may still be on transfer mechanism 501, thereby altering the aesthetic or functional qualities of ink layer 503. Any known method for cleaning transfer mechanism 501 may be utilized, for example, an adhesive plate may be used to make contact with transfer mechanism 501 and remove any undesired remaining components.

[0044] Figures 5 and 6 illustrate a third embodiment of the present invention. In the third embodiment, printable release layer 702 may be released from transfer mechanism 701 and onto the desired substrate 705 to provide a protective barrier to the ink and adhesive. During the application process, transfer mechanism is deposited (Step 711) with printable release layer 702. Following the application of printable release layer 702, ink layer 703 is deposited (Step 712) onto printable release layer 702. Then, binding layer 704 is deposited (Step 713) onto ink layer 703, where the layers 702, 703, and 704 may be dried and/or cured (Step 714) depending on the particular items utilized. After curing, layers 702, 703, and 704 may be applied (Step 715) to the substrate 705, and then the process may be repeated (Step 716). The third embodiment allows for the cleaning step of the above-described embodiment to be omitted. Such reduction in method steps likely reduces the costs of production of labels for application to substrates.

[0045] As indicated above, printable release layer 702 may provide desirable properties to the other label components before and after the label components are affixed to a substrate. The presence of a transparent printable release layer over the ink layer 703 may, in some embodiments provide additional properties such as antistatic properties stiffness and/or weatherability, and printable release layer 702 may protect ink layer 703 from, e.g., weather, sun, abrasion, moisture, water, etc. Printable release layer 702 may enhance the properties of the underlying ink layer 703 to provide a glossier and richer image. Printable release layer 702 may also be designed to be abrasion resistant, radiation resistant (e.g, UV), chemically resistant and/or thermally resistant thereby protecting the label components and, particularly ink layer 703 from degradation from such causes. Printable release layer 702 may also contain antistatic agents, or anti-block agents to provide for easier handling when the labels are being applied to containers at high speeds.

[0046] Printable release layer 702 may further contain UV light absorbers and/or other light stabilizers. Among the UV light absorbers that may be useful are the hindered amine absorbers available from Ciba Specialty Chemical Co. of Basel, Switzerland under the trade designations Tinuvin 111, Tinuvin 123, (bis-(l-octyloxy-2,2,6,6-tetramethyl-4-piperidinyl) sebacate; Tinuvin 622, (a dimethyl succinate polymer with 4-hydroxy-2,2,6,6-tetramethyl-l-piperidniethanol); Tinuvin 770 (bis-(2,2,6,6-tetramethyl-4-piperidinyl)-sebacate); and Tinuvin 783. Additional light stabilizers include the hindered amine light stabilizers available from Ciba Specialty Chemical Co. under the trade designation "Chemassorb", especially Chemassorb 119 and Chemassorb 944. The concentration of the UV light absorber and/or light stabilizer is in the range of up to about 2.5% by weight, and in one embodiment about 0.05% to about 1% by weight.

[0047] In some embodiments, printable release layer 702 may also contain an antioxidant. Any antioxidant useful in making thermoplastic films may be used. These include the hindered phenols and the organo phosphites. Examples include those available from Ciba Specialty Chemical Co. under the trade designations Irganox 1010, Irganox 1076 or Irgafos 168. The concentration of the antioxidant in the thermoplastic film composition may be in the range of up to about 2.5% by weight, and in one embodiment about 0.05% to about 1% by weight.

[0048] In the embodiment illustrated in Figures 7 and 8, the invention utilizes a flood technique that allows for the addition of an excess of a printable release layer 902 onto a transfer mechanism 901. In the embodiment, transfer mechanism 901 is deposited (Step 911) with a printable release layer 902. As indicated above, printable release layer 902 provides an amount of printable release layer material to sufficiently cover transfer mechanism. Following the addition of printable release layer 902, ink layer 903 is deposited (Step 912) onto printable release layer 902. In addition, binding layer 904 is deposited (Step 913) onto ink layer 903. In some embodiments, an ink layer and a binding layer may not completely cover a printable release layer. As indicated above, this may be done to ensure that an ink layer and a binding layer are sufficiently covered when the label is transferred to a substrate. In instances when a printable release layer is only applied to a portion of transfer mechanism, it may not sufficiently transfer to a substrate, thereby leaving the label with less than ideal protective qualities as desired.

[0049] Following the addition of layers 902, 903, and 904, the layers may be dried and/or cured (Step 914) as necessary. The layers 902, 903, and 904 may then be transferred (Step 915) to substrate 905. In addition, due to the remaining printable release layer following Step 915, transfer mechanism 901 may be cleaned (Step 916) prior to the repeat of the process (Step 917).

[0050] By way of further example, unlike the earlier described embodiments, a fifth embodiment may utilize a transfer sheet that may be dissolved by water or a solvent. For each transfer, a transfer sheet, which may be picked up from a stack of such sheets, ink layer and binding layer may be deposited onto the surface of the transfer sheet, ink layer and binding layer may be optionally cured, and ink layer and binding layer may be transferred to the substrates. In one embodiment of the invention, the transfer sheet may be made of water soluble or solvent soluble materials. Upon finishing of the transfer process, the transfer sheet may be washed away by the dissolving solvent or water. The transfer sheet may be transferred with the ink layer and binding layer onto the substrate before being washed away, or the transfer sheet may stay behind on a transport mechanism, such as a belt or diaphragm. Water soluble materials suitable for use as the transfer sheet include rice paper, polyvinyl alcohol (PVAc), ethylene vinyl alcohol (EVOH), starch and its derivatives, cellulose and its derivatives such as cellulose ethers, ethylcellulose polymers and other soluble materials.

[0051] In this exemplary fifth embodiment, a transfer sheet may be transferred to meet with a substrate on a moving belt. Due to the washing process, the moving belt may be constructed of a diaphragm with a plurality of orifices where heat may exit to aid in the washing process. In other embodiments, the moving belt may be constructed of a diaphragm without orifices, but that can be heated and wetted by known methods to also aid in the washing process.

[0052] In some embodiments, the ink layer and the binding layer may be formulated into one single layer. This formulation may contain colorants and also adhesive components. The ink and binding layer may be first deposited onto the transfer mechanism, optionally dried and or cured, and then applied to a substrate to be labeled.

[0053] In some embodiments of the invention, the components of the various ink layers, binding layers and printable release layers described above may be combined into a single layer. In such embodiments, the combination of all materials together may limit the amount of stages necessary for the creation of the labels.

[0054] These and other modifications and variations to the present invention may be practiced by those of ordinary skill in the art, without departing from the spirit and scope of the present invention, which is more particularly set forth in the appended claims. In addition, it should be understood that aspects of the various embodiments may be interchanged in whole or in part. Furthermore, those of ordinary skill in the art will appreciate that the foregoing description is by way of example only, and is not intended to limit the invention so further described in such appended claims. Therefore, the spirit and scope of the appended claims should not be limited to the description of the versions contained therein.
