Description

MATERIAL OMPUESTO IN LEAF, ADAPTED TO BE PRINTED FIELD OF THE INVENTION The present invention relates to composite materials that include a sheet or sheet, adapted to be printed with indicia, and a layer of pressure-sensitive adhesive, by which the sheet can be adhered to a substrate, and to methods for printing indications on those leaves.

BACKGROUND OF THE INVENTION The materials or papers for notes, composites, each of which comprises a sheet of paper and a narrow band of pressure-sensitive adhesive, easy to peel off, on a surface adjacent to an edge, by means of which the sheet is well known, are well known. it can be temporarily adhered to a substrate such as a document, for marking, to contain messages, or for other purposes. The blocks of those papers for notes are commonly sold by Minnesota Mining and Ref. 23081 Manufacturing Company, St. Paul, MN, under the trademark papers for "Post-it" notes. Those papers for notes have been printed with indications (for example, a message, an illustration, or a decoration), however, to date, in most cases such indications have been printed on large sheets or sheets of material from the which are formed the papers for notes, in such a way that the printing of indications in the papers for notes has been economically possible only when producing large amounts of papers for notes. U.S. Patent Application Serial No. 07 / 973,039, filed on November 9, 1992 (the entire contents thereof is hereby incorporated by reference), discloses a sheet assembly that includes sheets of paper to which Adhesive layers are adhered to, and a method for custom printing the sheet assembly and mounting or structuring it into blocks of note papers, using a copying machine. Although the sheet assembly described in that application was printed on printers of the type commonly used with personal computers or * and other types, which include laser printers, ink jet printers, and impact printers, it is not as versatile for printers. such use as may be desired, for various reasons, including that the coated sheets of the adhesive can not be easily printed on both sides as would be desirable.

DESCRIPTION OF THE INVENTION The present invention provides a composite material in foil or sheet comprising a sheet coated with pressure-sensitive adhesive, which is particularly adapted to be printed on one or both sides, in printers of the type commonly used with personal computers or of other types, and that include laser printers, ink jet printers and impact printers. Generally speaking, the sheet composite material, according to the present invention, comprises (1) a portion of the primary sheet having a first and second main, opposite surfaces, of a size adapted in such a way that it can be received by the printers (for example, 7.5 x 12 centimeters) and having a first and second opposite edges; (2) a portion of secondary sheet having first and second main surfaces, opposite, and having a first and second opposite edges, this portion of secondary sheet has a width, between its first and second edges, not greater than half of the width of the primary leaf portion between its first and second opposite edges; and (3) a layer of pressure sensitive adhesive which is firmly adhered on the first surface of one of the sheet portions, along its first edge. Composite forms in sheet form can be provided, which are easily printed on a printer. In those embodiments the first surface of the secondary leaf portion is adjacent to the first surface of the primary leaf portion, the first edges of the leaf portions, primary and secondary, are generally aligned, and the adhesive layer is It is placed between them and adhered so that it can detach, on the first surface of the leaf portion opposite to that to which it is firmly adhered. In those embodiments the secondary leaf portion may be either separated from or connected to, the primary leaf portion; the adhesive may be firmly adhered to any of the sheet portions; and the sheet portions can both have a layer of pressure sensitive adhesive, firmly adhered on their first surfaces, along their first edges, such that both portions of sheet can be printed, separated, and adhered to a substrate, through a layer of adhesive, after they have been printed. Also, those embodiments of sheet composite can be provided in a stack or block, with the sheet composite materials bonded in the stack or block by a layer of composite for the formation of blocks or notebooks which is adhered in such a way which can be peeled off, and which extends between the aligned lateral surfaces of the composite materials in sheets, stacked. Alternatively, certain embodiments of the sheet composite can be provided in a stack or block, without the use of the compound for the formation of blocks or notebooks. In these embodiments the first edges of the leaves, primary and secondary are connected along a line of weak structure, the first surfaces of the leaf portions are generally placed in a common plane, and the sheet composite can be folded easily along the path of the weak structure, to position the first surfaces of the primary and secondary leaf portions adjacent to each other, and to adhere in a detachable manner, the layer of pressure-sensitive adhesive, as length of the first surface of the opposite sheet portion, to which it is permanently adhered. Adhesive layers that are on a plurality of sheet composites, of those embodiments, can be adhered to the second, adjacent sheet material composite surfaces to form the stack or block, for example, with the adhesive layers. on the adjacent sheets at the same edge of the stack or block, or with the adhesive layers on successive sheets in the stack, on opposite sides of the stack or block. The adhesive used in the adhesive layer can be an easy release adhesive or an adhesive of the type that allows a sheet to be placed in one place and then in others, or it can be a pressure sensitive adhesive, difficult to peel off. If necessary, the sheet composite may include a layer of release material, on the first surface of the sheet to which the adhesive layer is adhered, so that it can be peeled off, to facilitate the separation of the sheets afterwards. that the composite material in sheets has been printed. Between the sheet portions, joined along one edge, to hold them together before and during printing, a small amount of adhesion is needed, almost immeasurable. To be sure that portions of sheets that are not bonded to one another will remain adhered to the adhesive, before and during printing, the force required to detach the sheet portions of the sheet composite prior to printing will have to be removed. be at least 3 grams per 25 millimeters adhesive width (and preferably greater than about 5 grams per 25 millimeters adhesive width) along the stripping line, when the sheet portions are separated by peeling at an angle of 90 degrees and 300 millimeters per minute. The force required to detach the leaf portions by detachment, after the sheet composite is printed on a laser printer of the type commercially designated as "LaserJet III" which is commercially available from Hewlett Packard Corporation of Palo Alto, California, shall be less than 300 grams per 25 millimeters (and preferably less than 25 grams per 25 millimeters) of adhesive width, along the stripping line, when the leaf portions are separated by peeling at an angle of 90 degrees to 300 millimeters per minute, to ensure that they can be separated easily and cleanly. The sheets may be of any conventional material (e.g., conventional bond paper, or paper coated with clay, opaque or translucent polymeric material, or carbonless paper). The adhesive used in the layers of pressure-sensitive adhesive may be a readily releasable pressure-sensitive adhesive (eg, one comprising copolymer, elastomer, sticky microspheres) in which case the opposite surface, when stacked or Covers for printing, can be free of coating for detachment; or a more aggressive, conventional pressure sensitive adhesive may be used, in which case the sheet may include a release coating, where appropriate. Suitable release or release materials for these adhesives can be selected from acrylates, urethanes, silicones, fluoropolymers, chromium complexes, and the like known in the art. A method for printing a custom printed sheet may include providing a printer of the type commonly used with personal computers or other types, such as a laser printer, an ink jet printer, or an impact printer; providing a manually operable means for forming a message in an electronic form, capable of operating the printer in such a way that the printer prints the message when it is operated, and the electronic form of the message is sent to the printer; providing one of the sheet composite materials, described above, having the first surfaces of its primary and secondary leaf portions, placed adjacently and adhered together by the layer of pressure sensitive adhesive; forming a desired message using the manually operable means; send the message electronically to the printer to make the printer work; Feed the sheet composite through the printer (that is, using either the paper feed tray or the "bypass" feed feature) so that the message is printed on the composite in sheet; and separating the secondary leaf portion from the primary leaf portion, such that the printed sheet composite can be adhered to a substrate or other sheet composite materials, printed, to form a block or notebook, using the layer of pressure sensitive adhesive. Where the sheet composite material is provided in a stack or block, the method may further include the steps necessary to remove the composite material in the sheet, from the stack or block, and, if necessary, manually fold the composite into sheet , along the path of weakness or rupture, before the feeding step, to place the first surface of the primary and secondary leaf portions, to that to which the layer of pressure-sensitive adhesive adheres along of the first surfaces of both portions of the sheet. Also, wherein the leaf portions, primary and secondary, are joined along their first edges and the adhesive layer adheres firmly to the first surface of the secondary, leaf portion; the method may further include printing a plurality of custom printed sheets, using the steps of the method set forth above; and adhering the adhesive layers that are on the secondary sheets, to the second surfaces of other secondary sheets, with the edges of the secondary sheets aligned to form a block or notebook. The sheet material and method, described above, provide a convenient and versatile approach that can be used by individuals or commercial establishments to custom print small amounts of papers for notes, labels, markers, signs, receipts, and Similar. The adhesive is covered and protected during printing, however it continues to be easily exposed, even after exposure of the sheet composite, to the pressures and temperatures involved in electrophotographic printing. The sheet composite material, printed individually, can be retained with its sheet portions adhered together until ready for use. Alternatively, the sheet portions of various printed sheet composite materials can be separated and these sheet composite materials can then be stacked to form a block or booklet. Subsequently, the sheet portions of those individually printed sheet composites can be separated, or the printed sheet composites can be separated from the block or booklet and adhered to the surface of a substrate.

Analyzes to determine the force required to separate the leaf, secondary, portions of the leaf, primary portions, after they were adhered to each other, and before printing, were made in each sheet composite, separating the sheet portion, secondary, of the leaf portion, primary, along the line of weakness that lies between them, acquiring the leaf, primary and secondary portions, together, in the position in which they would be adhered together in the list or prepared position, as if they were still joined along the line of weakness, laminating the sheet portions, together, in the manner described in the FINAT # 2 method, joining the primary leaf portion to a platform on a test machine, using a double coated tape, with the secondary sheet portion on the side of the primary leaf portion, opposite the platform, causing the test machine to detach the sheet portion, secondary, of the leaf portion, primary, at a speed of 300 millimeters per minute, while pulling the secondary leaf away from the primary leaf, at an angle of 90 degrees with respect to the first surface of the primary leaf, and recording the force required to detach the leaf, secondary, portion of the leaf, primary portion. Analyzes to determine the force required to separate the secondary leaf portions from the primary leaf portions, after they adhered to each other, and from which they were printed, were made on each sheet composite, with their portions of leaves Adhered and laminated together, in the ready or ready position, printing indications on the primary leaf portion, using a "LaserJet III" printer commercially available from the Hewlett-Packard Corporation of Palo Alto, CA, making a cut of 0.5 millimeters from the first edges of the primary and secondary leaves, to remove the path of weakness, joining the primary leaf portion to a platform on a test machine, using a double-coated tape, with the leaf, secondary portion, on the side of the portion of sheet, primary, opposite the platform, causing the test machine to detach the secondary leaf portion of the primary leaf portion at a speed of 300 millimeters per minute, while pulling the secondary leaf, separating it from the leaf primary to a 90 degree angle of the first surface * e the primary leaf, and recording the force required to detach the secondary leaf portion of the leaf portion p rimaria. Example 1; Sheet composites were manufactured, similar in general to the sheet composite materials 10 illustrated in Figure 1, using 14 cm x 42 cm pieces of 9 kg (20 lb) bond paper commercially available under the trade designation of "Astrobright" by Wausau Papers, Wausau, WI. A release material was prepared for the coatings 26, by mixing 100 g of "Syl-Off" 7610 and 5 g of "Syl-Off" 7611 (both commercially available from Dow Corning Corp.), 50 g of zinc oxide of 3 microns, and 100 g of 2-butanone. The coverings 26 of release material were applied along 42 cm long edges of the sheets, in strips or bands 2 cm wide, by drag coating (i.e., by dragging the sheets of paper underneath). of a smooth or smooth bar) after which the coatings 26 of the lightening material were dried and cured. The adhesive to be used in the adhesive layers 24, was prepared from an organic solvent suspension (i.e., with an 8% solids content) of 10 parts of the 95% iso-octylacrylate copolymer and 5% acrylic acid, and 90 parts of sticky elastomeric copolymer microspheres, ranging in diameter from about 10 to 150 microns. The adhesive was coated or applied on a silicone treated paper, using a nozzle with a 0.2 mm hole, and dried. The adhesive, on 13 mm wide strips of the silicone-treated and adhesive-coated paper, was applied parallel and at a distance of 3 millimeters to the coatings or coatings 26 of the release material, on the paper sheets, and was laminated to the leaves, after which the strips of paper treated with silicone were removed or removed. Subsequently, the sheets were micro-perforated to form the trajectories of weakness 23. The secondary, sheet portions 17 were turned around the weak trajectories 23 to adhere the adhesive layers 24 to the coverings 26 of the release material. The resulting composite sheets 10 were cut to give dimensions of 12.2 millimeters by 20.5 millimeters and printed on their second surfaces using the laser printer, Hewlett Packard, "LaserJet III". Some of the printed, printed composite materials did not bend but were attached to substrates such as custom printed notes, while others did not bend and the second panel was separated before use as note papers. Still, others that were not bent, were aligned by manually arranging the sheets on the bottom edge, and stacked to form paper blocks for custom printed notes. The test described above was performed on the sheet composites and showed the force required to separate the leaf, secondary, portions of the leaf, primary portions, after the primary and secondary leaf portions were adhered to each other by the adhesive layer, in its ready or ready position, but before printing, was approximately 0.79 grams per centimeter (2 grams per inch), and that the force required to separate the secondary sheet portions from the portions of Primary leaf after they were printed, was approximately 2.36 grams per centimeter (6 grams per inch). Example 2: Sheet composites were manufactured, generally similar to sheet materials 40, illustrated in Figure 5, using the materials and techniques described in Example 1, except that second micro-perforations were made in the sheets, form the lines of weakness or break 42. The sheet composite materials were printed using the Hewlett Packard laser printer "LaserJet III", passing the composite materials in sheet 40 through the printer, twice, to print both the portion of leaf, primary, lia, like the leaf portion, secondary, 17a. Some of the printed sheets were placed to be used as papers for custom printed notes, others were stacked in an aligned manner by partially unfolding the leaf, secondary portions, placing one sheet on top of the next, and then the sheets were separated along lines of weakness 42 to form two piles or blocks. The analyzes described above were performed on the sheet composite materials 40 and showed that the force required to separate the leaf, secondary, portions of the leaf, primary portions, after their leaf portions, primary and secondary, were adhered jointly by the adhesive layer, in its ready or ready position, but before printing, was approximately 0.79 grams per centimeter (2 grams per inch), and that the force required to separate the secondary sheet portions from the portions of primary leaf, after they were printed was approximately 2.36 grams per centimeter (6 grams per inch). Example 3: Sheet composites were made, generally similar to the sheet materials 50 illustrated in Figure 7, using the sheets of 9 kilogram (20 pounds) bond paper and the release material, described in Example 1 Adhesive layers 64 and 65 were fabricated using "Scotch" 9415, a doubly coated tape having an easy release adhesive on one side and a permanent adhesive on the other, and which is commercially available as "Scotch" 9415 from Minnesota Mining and Manufacturing Company, St. Paul, MN, by laminating the permanent side of the tape, to the sheet, and removing the coating, to expose the "low tack" adhesive. The coating 66 of the release material in the primary leaf portion 51 was coated, dried, and cured, as described in Example 1, to provide a 30 millimeter wide coating of release material, located at 57 millimeters of an edge. The layers of adhesive, 65 and 64, 12 millimeters wide, made of double coated tape, were laminated 2 millimeters and 45 millimeters from that same edge, and the coatings of the tape were removed. The release material 66, on the secondary sheet portion 57, was provided by adhering thereto a strip, 25 millimeters wide, of "Scotch" tape # 810, available from Minnesota Mining and Manufacturing Comp ^ ny, strip or band. which provided, both the release material 66 and the reinforcement for the secondary sheet portion 57. The sheets were microperforated in parallel, 34 millimeters from the edges of the paper sheets to form the trajectory of weakness 63. Other trajectories of weakness (no shown in figure 7) were made by microperforation, to divide the leaves into one-quarter sizes. The sheets were printed on both sides with a Hewlett Packard laser printer "LaserJet III". Some sheets were not folded and joined as papers for custom printed notes, others were not folded and the second panel was separated before being used. The first panel was used as a note paper, and the second panel was attached to the document, such that the tape reinforced section extended beyond the edge of the document. The analysis described above was performed on the composite materials in sheets 50 and demonstrated the strength required to separate the portions of secondary leaves from the primary leaf portions, after their primary and secondary leaf portions adhered to each other by the adhesive layer, in its ready or ready position, but before printing, it was approximately 0.79 grams per centimeter and 2.36 grams per centimeter (2 grams per inch and 6 grams per inch), respectively, for the adhesive Adhered to the material for detachment, and for the adhesive adhered to the "Scotch" tape # 810, and that the force required to separate the secondary leaf portions from the leaf, primary portions, after they were printed, was approximately "-.94 grams per centimeter and 4.72 grams per centimeter (10 and 12 grams per inch). ), respectively, for the adhesive adhered to the release material and for the adhesive adhered to the "Scotch" # 810 tape.; Sheet composites, generally similar to the composite materials in sheets 70 illustrated in Figure 8, were made using the paper and the release materials described in Example 1, the transfer tapes and the doubly coated tapes, designated commercially from respective way as "9415" and "Scotch" # 945 that are available from Minnesota Mining and Manufacturing Company. The coatings 98 of d-release material, which were 25 millimeters wide and which were located 17 millimeters from one of the edges of the sheets, were applied in the manner described in example 1. The coatings 96 of the material for detachment were applied similarly, 2 millimeters from the opposite edges of the leaves. The adhesive layers 97 were provided by laminating strips or bands 12 millimeters wide from the transfer belt "945" to 2 millimeters from the edges of the sheets. The adhesive layers 94 were provided by laminating strips of the doubly coated tapes "9415" on the sheets, 25 millimeters from their edges. The sheets were micro-perforated to form the trajectories of weakness 88 and 89. The sheet composites 70 were folded along the lines of weakness 88 and 89 to the ready or prepared position, illustrated in Figure 8. The composite materials in sheet 70 they were printed with a Hewlett Packard laser printer "LaserJet III". The leaf, secondary and tertiary portions, 77 and 82, were separated from the leaf, primary portions. The tertiary leaf portion of a sheet composite was adhered to a cabinet through the adhesive layer 97, and a photograph was adhered to the adhesive layer 94. The analysis described above was performed on the sheet composite materials 70 and demonstrated the force required to separate the leaf, secondary, portions of the leaf, primary portions, after the leaf, primary, and secondary portions, they were adhered to each other, by the adhesive layer, in their ready or ready position, but before printing, it was approximately 0.79 grams per centimeter and 2.36 grams per centimeter (2 and 6 grams per square inch respectively) , for the adhesives 94 and 97, and that the force required to separate the leaf, secondary, portions of the leaf, primary portions, after they were printed, was approximately 2.36 and 5.12 grams per centimeter (6 and 13 grams) per inch) respectively, for adhesives 94 and 97. Example 5: Sheet composites were manufactured, generally similar to sheet composite materials 100, illustrated in Figure 9, from of the sheets described in example 3, cutting the microperforation of the edge of the sheets to form two separate sheets 101 and 107. Those sheet composite materials, 100, were printed and put to use as a note paper and as a supplementary signaling . The analysis described above was carried out on sheet material 100 and showed essentially the same values reported previously in Example 3. Example 6; A stack or block of sheet composite materials, similar to those illustrated in Figure 2, was made from sheet composite materials 10 of the type described in Example 1, by applying coating 27 of release material, to its second surfaces 14 and 19. The material for the coating or for release was prepared in accordance with what is described in US Patent No. 5,154,962 (Mertens, et. al.), example 41, except that the material was made in reactors of 208 liters (55 gallons) and the chemical composition was 47.0% methyl acrylate, 36.5% n-vinylpyrrolinone, 5.3% acrylic acid, and 31.3% silicone macromer. Coatings 27 of release material were applied to 10 of the composite materials in sheets 10., using a smooth roller, and dried. The sheet composites were stacked to form the block as illustrated. The block was then placed in a dispenser, generally of the type illustrated in US Patent No. 4,986,440, from which the sheets were conveniently dispensed or supplied and could be used either as a note paper without printing, or could bend along the line of weakness or break 23, print and then use. Example 7: Sheet composites were made, generally similar to the composite materials in sheets 10 illustrated in Figure 1, using a paper coated with 27.2 kilogram (60 pounds) clay. The release material, for the coatings 26, was prepared by mixing 95 parts of "Syl-Off" 7610 and 5 parts of "Syl-Off" 7611 (both commercially available from Dow Corning Corp.), diluted to 10% of solids in 2-butanone. The release material overlays 26 were applied as in Example 1. The adhesive for use in the adhesive layers 24 was provided by the "Scotch" adhesive transfer tape 924. Subsequently, the sheets were micro-perforated to form the trajectories of the adhesive. Weakness 23. The secondary, sheet portions, 17, were turned or folded around the weakened trajectories 23 to adhere the adhesive layers 24 to the overlays 26 of the release material. The resultant sheet 10 composites were printed on their second surfaces using the Hewlett Packard laser printer "LaserJet III". Some of the printed sheet composite materials were folded and bonded to substrates that included brick walls, as signs. The separation of the leaf portions caused some delamination of the paper and caused the paper to curl or ripple. The analysis described above was performed on the sheet composites, and showed that the force required to separate the leaf, secondary, portions of the leaf, primary portions, after the primary and secondary leaf portions had been adhered to others by the adhesive layer, in its ready and prepared position, but before being printed, it was approximately 29.5 grams per centimeter (75 grams per inch), and that the force required to separate the secondary sheet portions of the primary leaf portions after they were printed was approximately 110.24 grams per centimeter (280 grams per inch). The present invention has been described with reference to various modalities thereof. It will be apparent to those skilled in the art that many changes can be made in the described embodiments, without departing from the scope of the present invention. For example, the trajectories of weakness between the leaf portions can be provided in many ways other than the perforations that will join the edges of the leaf portions together, and which allow the leaf portions to pivot or rotate relative to each other. along the trajectories of weakness, while providing sufficient integrity such that the sheets do not separate along that line, while printing, and if desired can be cut or peeled off along the line of weakness . Those forms include weakening a sheet of material, cutting, or marking the sheet with chemical treatments, and the like, and where two sheets are used to form the leaf portions, glueing their adjacent edges together, or joining their adjacent edges in a row. length of tape coated with adhesive or similar. Thus the scope of this present invention should not be limited to the structures and methods described in this application, but only by the structures and methods described by the claims and equivalents thereof. It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
