Description

PRINTABLE SHEET FOR WATER-RESISTANT INK JET BACKGROUND OF THE INVENTION The present invention is directed to an ink jet recording substrate. In particular, the present invention relates to a substrate which is at least partly water-repellable and substantially water-resistant. The present invention is further directed to a multi-layer article consisting of the ink-jettable substrate at least partially connected to a substantially non-porous material. Moreover, the present invention is directed to a method for producing the multilayer article. This application claims priority for 10 / 654,377, filed on September 3, 2003; 10 / 654,119, filed September 3, 2003, and 10 / 654,433, deposited on September 3, 2003. It is known in the art to size paper with various appressing components in order to retard or prevent the penetration of liquids into the structure. For example, him "Internal sizing" consists of introducing appressing materials in the pulp during the papermaking operation. The sizing materials are precipitated on the fibers primarily in order to control the penetration of liquids into the final dry paper. In addition, "surface sizing" involves the application of dispersions of film-forming substances, such as converted starches, gums and modified polymers, to pre-formed paper. Surface sizing imparts resistance to paper. The use of paper ready for printing with an inkjet printer that predominantly contains water-based inks can give image papers that tend to curve in the form of tubes. The use of unprimed paper may result in migration of the image through the sheet and interference with the image on the other side, if one side of the imaged sheet comes in contact with water. Various attempts have been made in the art to solve the above problems. For example, U.S. Patent 5,709,976 describes a paper substrate coated with a hydrophobic barrier material and an image receiving layer. US Pat. No. 6,140,412 shows a process for coating paper with an aqueous solution of cationic polyurethane resin. Japanese Patent (JP) 11216945 describes a process for coating paper with a composition including polyvinylpyrrolidone, an emulsion of polyurethane resin, polyvinyl alcohol and a cationic resin. In addition, U.S. Patent 6,020,058 discloses an acrylic composition and U.S. Patent 6,025,068 discloses a urethane-acrylic copolymer. US Patents 4,861,644 and 5,196,262 disclose a sheet of microporous material that includes a linear ultra-high molecular weight polyolefin matrix, a large proportion of finely divided water insoluble siliceous filler and interconnecting pores. U.S. Patent No. 6,025,068 teaches a method of coating a microporous polyolefin substrate with a coating composition that includes a binder dissolved or dispersed in a volatile aqueous liquid medium. Another coating composition for ink-jet recording materials is described in Japanese Patent (2001) JP-A-0484881. This reference describes a coating composition which includes a nonionic or anionic polyurethane and the reaction product of a mono-methyl secondary amine and epichlorohydrin. Japanese Patents (JP) 11268406 and (JP) 2000153667 describe cationic polyurethanes useful in water-tight coatings for substrates for inkjet printing.

An ink-jet recording medium that is durable, water-resistant and capable of recording accurate images when an ink-jet printing ink is applied to it is still needed.

The method includes the following steps: (a) having an ink-jettable substrate having an upper surface and a lower surface, (b) disposing of the coating composition described above and (c) applying the coating composition to at least one surface of the substrate which can be registered by an ink jet.

A variety of ink-jettable substrates known in the art can be used in the present invention. In a non-limiting embodiment, the ink-jettable substrate may include a cellulosic-based paper. U.S. Patent Nos. 4,861,644 and 5,196,262 describe microporous substrates suitable for use in the present invention.

In a non-limiting embodiment, the polyethylene can be linear high molecular weight polyethylene with an intrinsic viscosity of at least 10 deciliters / gram and the polypropylene can be high molecular weight linear polypropylene with an intrinsic viscosity of at least 5. deciliters / gram. As used herein and in the claims, "high molecular weight" refers to a weight-average molecular weight of 20,000 to 2,000,000. The intrinsic viscosity can be determined using a variety of conventional techniques. As recorded herein and in the claims, the intrinsic viscosity is determined by extrapolating to zero concentration the reduced viscosities or inherent viscosities of various diluted solutions of the polyolefin, where the solvent is distilled decahydronafatnet, to which has been added a 0.2 weight percent of 3,5-di-tert-butyl-4-hydroxyhydrocinnamic acid, neopentanotetraylester [CAS Registry No. 6683-19-. The reduced viscosities or inherent viscosities of the polyolefin are determined from the relative viscosities obtained at 135 ° C using an Ubbelohde viscometer No. 1.

On a free coating base, free of printing ink, free of impregnation and pre-bonding, the pores constitute at least 35 volume percent of the microporous substrate. In alternative non-limiting embodiments, the pores can constitute at least 60 volume percent of the microporous substrate, or from 35 percent to 80 percent, or from 60 percent to 75 percent by volume of the microporous substrate . In alternative non-limiting embodiments, the siliceous particles may be in the form of ultimate particles, aggregates of ultimate particles or a combination of both. As used herein and in the claims, the term "ultimate particles" refers to discrete small particles of colloidal polymerized silicic acid units that constitute the amorphous silica. The term "aggregate", as used herein and in the claims, refers to a structure in which the latter particles condense to produce an open, but essentially continuous, structure of chains or a solid structure of substantially interconnecting pores. In one embodiment, the siliceous particles are finely divided. As used herein and in the claims, "finely divided" refers to a maximum retention of 0.01% by weight in a 40 mesh screen sieve. In another non-limiting embodiment, the siliceous particles can be substantially insoluble. As used herein and in the claims, the term "substantially insoluble" refers to amorphous silica that exhibits a solubility in reproducible equilibrium in water that can vary between 70 ppm and more than 150 ppm in water at a temperature of 25 °. C. It is believed that variations in solubility may be due to differences in particle size, in the state of internal hydration and in the presence of traces of impurities in the silica or absorbed on its surface. The solubility of the silica can also depend on the pH of the water. As the pH increases from neutral (ie, pH of 7) to alkaline (ie pH greater than 9), the solubility of the silica may also increase. (See "The Chemistry of Silica," R.K. Iler, Wiley-Intersciences, NY (1979), pp. 40-58).

In a non-limiting embodiment of the present invention, at least 90 percent by weight of the silicone particles used in the preparation of the microporous substrate can have particle sizes of 5 to 40 microns. The particle size can be determined by a variety of conventional techniques. In the present invention, a Multisizer Particle Size Analyzer (Coulter Electronics, Inc.) was used, where, before analysis by the Coulter Analyzer, the filler was stirred for 10 minutes in Isoton II electrolyte solution (Curtin Matheson Scientific, Inc.) using a four-blade propeller stirrer of 4,445 centimeters in diameter. In a non-limiting embodiment, at least 90 percent by weight of the siliceous particles can have particle sizes of 10 to 30 microns. It is believed that sizes of filler agglomerates can be reduced during the processing of the ingredients to prepare the microporous substrate. As suitable siliceous particles, a wide variety known to one skilled in the art may be included. Non-limiting examples may include, but are not limited to, silica, mica, montmorillonite, kaolinite, asbestos, talc, diatomaceous earth, vermiculite, natural and synthetic zeolites, cement, calcium silicate, silicate aluminum, sodium and aluminum silicate, aluminum polysilicate, alumina and silica gels and glass particles. In a non-limiting embodiment, silica and clay can be used as siliceous particles. In another non-limiting embodiment, precipitated silica, silica gel or fumed silica can be used. In general, silica can be prepared by combining an aqueous solution of a silicate, of soluble metal with an acid.

Polymer processing techniques are described in US Pat. W ° 4,892,779. The present invention is more particularly described in the following examples, which are intended to be merely illustrative, since numerous modifications and variations thereto will be apparent to those skilled in the art. Unless otherwise specified, all parts and percentages are by weight and all references to water are intended to be deionized water. EXAMPLES Example 1 A coating composition of the present invention was prepared by diluting in a stainless steel mixture tank under high speed mixing with a head mixer an anionic polyurethane dispersion at 61.5% by weight solids sold under the trade name WitcoBond® 234, from Crompton Corporation, Greenwich, Connecticut, at 9.22% by weight solids. In a separate feed tank, a 55% by weight solids solution of an amine polyamide reacted with epichlorohydrin, sold under the trade name CinFix NF by Stockhausen GmbH & Co. KG, Krefeld, Germany, at 5.78% by weight solids and was subsequently added to the diluted anionic polyurethane dispersion and the mixture was mixed for 15 minutes. The pH was adjusted with glacial acetic acid to 5, 0 ± 0.5. The total resin solids of the mixture were 7.5% and the viscosity of the mixture was 46 cps, measured using a Brookfield viscometer, RVT, axis No. 1, at 50 rpm and 25 ° C. Examples 2-5 A coating composition was prepared as described in Example 1 and applied to microporous Teslin® substrates. Two substrates were coated (Examples 2 and 4) using a dosing bar. A dosing bar was placed 1-2 inches above the Teslin® sheet, parallel to the top edge. A quantity of 10-20 ml of coating was introduced into a disposable plastic syringe. The coating was deposited as a strip of beads (approximately 1/8 inch wide) directly to the side of the dosing bar and touching it. The bar was brought completely through the Teslin® sheet, trying a continuous / constant speed. The resulting wet sheet was placed in a forced air oven, secured and dried at 95 ° C for 2 minutes. The dried sheet was removed from the oven and the same coating procedure was repeated on the opposite side of the sheet. The sheet was then printed and studied. For coating compositions having a total resin solids of 7.5%, the viscosity was 46 cps and for 10.0% solids the viscosity was 63 cps. The viscosity values were measured using a Brookfield viscometer, RVT, axis No. 1, at 50 rpm and 25 ° C. The substrates were coated (Examples 3 and 5) using a flexographic or gravure coating method to apply the coating. In this coating method, a line consisting of two coating stations, each with a forced air drying oven, was used. Each coating station consists of a coating feeding chamber, an anilox roller and a rubber application roller. The coating feeding chamber was supplied with a coating maintenance tank and a pump. Both sides of the Teslin® sheet were coated. The apparatus was equipped with an anilox roll of 7"BCM" (billions of cubic microns), the line speed was 180 fpm, the oven temperature was 105 ° C (220 ° F) and 8 passes were made by roller, which translates into four passes per surface. The coating compositions were applied with a layer weight of approximately 0.73 g / m2 (total of the front and the back). The layer weight was determined as follows: the weight of layer of "X" grams of coating (as dry solids) consumed in the coating of "Y" square meters of Teslin® is "X divided by Y" grams per square meter. Table 1 shows the characteristics of the sheets produced. TABLE 1 * BPS = shocks per surface. The resulting coated sheets were printed with a test printing pattern on an HP970 Model Inkjet Printer (Hewlett Packard Company). The color bars of the test print pattern were measured for optical density by immersion in deionized water at room temperature for a period of 15 minutes, removing from the water and leaving to air dry for one hour and measuring each color in terms of optical density. The optical density of cyan (C), magenta (M), yellow, black (K) and composite black (CMY) was measured using a MacBeth A SWER II densitometer Model RD922, manufactured by Kolimorgen Instrument Corporation, before and after soaking with Water. The results are shown in Table 2.

TABLE 2 Example 6 A solution was applied to 9.22% by weight solids of WitcoBond 234 to a Teslin® TS1000 substrate using a dosing bar as described in Examples 2-5. Immediately thereafter, a solution of 5.78% by weight of CinFix NF solids was applied in a similar manner to the substrate. The Teslin® TS1000 was then coated at 95 ° C for 2 minutes. The dried sheet was removed from the oven and the same coating procedure was repeated on the opposite side of the sheet. A test print pattern was printed on the coated Teslin® using an HP970 Ink Jet Printer as described in Examples 2-5. Based on visual inspection, the printed image showed excessive ink bleeding and poor drying properties. Example 7 A coating composition was prepared by diluting in a stainless steel mixing tank with high speed mixing with a head mixer an anionic polyurethane dispersion to 61.5% by weight solids sold under the trade name WitcoBond. ® 234, from Crompton Corporation, Green ich, Connecticut, at 9.22% by weight solids. In a separate feed tank, a 55% by weight solids solution of an amine polyamide reacted with epichlorohydrin sold under the trade name CinFix NF was diluted by Stockhausen GmbH & Co. KG, refeld, Germany, at 5.78% by weight solids. The WitcoBond 234 dispersion was added to the diluted solution of CinFix NF. The resulting suspension demonstrated an unacceptably heavy precipitate which was a Polisal of CinFix NF and WitcoBond 234. Examples 8-10 Coating compositions were prepared as in Example 1 and applied to silk fabric (0.10 Ib / square yard, 5 mils caliber), woven cotton (0.34 lb / square yard, 13.6 mils caliber) and a polypropylene / cellulose nonwoven substrate (0.14 lb / sq. Yard, 9.5 mils caliber) . For each coated material, a sheet (8.5"x 11") was attached to a support sheet of 15"x 20" x 20 mils. A dosing bar was placed 1-2 inches above the top of the sheet, parallel to the top edge. A quantity of 10-20 ml of coating was introduced into a disposable plastic syringe. The coating was deposited as a strip of beads (approximately 1/8 inch wide) directly to the side and touching the dosing bar. The bar was brought completely through the sheet at a continuous / constant speed. The resulting wet sheet was placed in a forced air oven, secured and dried at 95 ° C for 2 minutes. The dried sheet was removed from the oven and the same procedure was repeated on the opposite side of the sheet. The sheet was then attached with a ribbon to a transparency sheet to obtain rigidity and was then ready to be printed and studied. The coating compositions were applied with a layer weight of approximately 0.73 g / m2 (total front and rear). The layer weight was determined as previously described in Examples 2-5.

Examples 8-10 were printed with an inkjet printer, Model HP970 from Hewlett Packard Company, Pa-lo Alto, California, and compared with the same uncoated substrates. After printing, each sheet of the rigid transparency sheet was removed. The types of coated and uncoated printed sheets were soaked in water at room temperature for 5 days. The optical density was measured after 5 days of soaking. The optical density of cyan (C), magenta (M), yellow (Y), black (K) and composite black (CMY) was measured using a Macbeth Densitometer ANSWER II Model RD922, manufactured by Kolimorgen Instrument Corporation, before and after the soaking with water. the images recorded for the coated substrates remained intact after 15 minutes, ie, the ink did not bleed or that the optical density of the image was not significantly reduced for each sample. The uncoated sheets bled immediately and completely washed the printed image in the 15 minute soak time. The printed image on each of the coated substrates did experience bleeding from the ink after exposure to the 5-day water soak, as seen by the values of the optical density. The resulting printed images were discolored, but had good line sharpness and readable text.

In a mixing vessel with high speed mixing with a head mixer, an anionic polyurethane dispersion at 61.5% by weight solids sold under the trademark Witcobond W-234, from Crompton Corporation, Greenwich, Connecticut, was diluted. with deionized water to a dispersion at 10.0% by weight of solids. In a separate vessel, a 55% by weight solids solution of an amine polyamide reacted with epichlorohydrin sold under the trade name CinFix NF, Stockhausen GmbH & Co. KG, Krefeld, Germany, with deionized water to a solution at 10.0% by weight solids and was then added to the diluted dispersion of anionic polyurethane. The mixture was mixed for fifteen minutes after completion of the addition. The resulting mixture contained 40 parts by weight of CinFix NF solids and 60 parts by weight of Witcobond W-234 solids. A second coating was prepared as described above, with the exception that the CinFix NF was replaced on an equivalent dry solids base with CinFix DF. Reference is made here to this second coating composition as 01 / KDF. CinFix RDF is an aqueous solution of po-li (diallyldimethylammonium chloride) at 31% solids sold by Stockhausen GmbH & Co. KG, Krefeld, Germany. CinFix RDF was diluted to 10.0% by weight solids before addition to Witcobond W-234. A third coating was prepared as described above for the composition "01", except that the CinFix NF was replaced on an equivalent dry solids base with diallyldimethylammonium chloride. Reference is made here to this third coating composition with "Ol / DADMAC". Diallyldimethylammonium chloride is marketed by Al-drich Chemical Company, of ilwaukee, WI, as a 65% solution in water. It was diluted to 10.0% by weight solids before addition to Witcobond W-234. A fourth coating was prepared as described above for composition "01", except that the CinFix NF was substituted on a dry solids base equivalent with the reaction product of equimolar amounts of di-ethylamine and epichlorohydrin at 30 ° C. % solids in water. Reference is made herein to this fourth coating composition as "01 / DEA-EPI". The reaction product was not completely miscible with water in the mixture of 30/70 parts by weight needed for 30% solids and, therefore, acidified to a pH of 5 with acetic acid to make it soluble in water for use in the coating. It was diluted to 10.0% solids before addition to Witcobond W-234. Teslin® sheets TS1000 and SP1000 were coated on both sides with each of the aforementioned coatings using a # 9 rod. The coating was applied to the front surface, dried for a period of two minutes at a temperature of 95 ° C and then applied to the back surface and dried for two minutes at 95 ° C. The finished sheets were then printed with a pattern on a Hewlett-Packard 960C printer with a setting ???? Premium Photo Paper - Glossy. "The color density of the printed color bar section of the pattern was measured using a X-Rite Model 418 Densitometer calibrated on a white slab pattern. Each sheet was immersed in a beaker with deionized water overnight (ie, 14 hours) .The sections of the water baths were then removed and allowed to air dry for a period of four hours. then measured the color density after soaking.The results are shown in the following table: Substrate coating Soak CMY C-100 M-100 Y-100 K-100"01" XS1000 No 1,31 1,23 1, 24 0,33 1,31 01"Yes. 1,33 1,16 1,20 0,92 1,33"01" SP1000 No 1.32 1.23 1.25 0.93 1.32"01" Yes 1.32 1.16 1.19 0.90 1.33"01 / RDF" TS1000 No 1.52 1.10 1, 20 0.88 1.55"01 / RDF" Yes 1.54 '1, 04 1.10 0, 84 1.55"01 / RDF" SP1000 No 1.16 0.97 1.28 0.99 1.20"01 / RDF" Yes 1,13 0,91 1,21 1,00 1,15"01 / DADMAC" TS1000 No 1, 73 1.13 1, 01 0.82 1, 80"01 / DADMAC" Yes 1.53 0.11 0.17 0.13 1.55"01 / DADMAC" SP1000 No 1.37 0.91 1, 44 1, 06 1.58"01 / DADMAC" Yes 0.26 0.14 0, 20 0.15 0.16"01 / DEA-EPI" TS1000 No 0.81 0.98 0.85 0.57 0.81"01 / DEA-EPI" Yes 0, 60 0, 66 0,36 0, 24 0, 59"01 / DEA-EPI" SP1000 No 0.75 0.92 0, 82 0, 55 0, 76"01 / DEA-EPI" Yes 0.54 0.62 0.35 0.23 0.55 The coating "01" on any of the substrates exhibited an acceptable color density and water resistance and there was no visual evidence of color bleeding. Based on the visual inspection, the printed images were dry and clear. The coating "01 / RDF" also showed acceptable color density and water resistance, showing no visual bleeding. However, based on the visual inspection, there was a slight "blotting" or blurring of the image on the SP1000 substrate. The coating "01 / DADMA.C" had a high color density before soaking, but, based on visual inspection, the inks did not dry completely on the surface and were almost completely removed from the two substrates during the soaking In addition, based on visual inspection, the images were not distinctive, significant color bleeding and the images were not clear. The "Ol / DEA-EPI" coating had a low color density on both substrates and the water resistance was low. Based on the visual inspection, there was no color bleeding and the images were clear, but they appeared pale. Example 12 A coated Teslin® sheet was placed on top of a 20 inch x 25 inch sheet of 0.10 inch polyvinyl chloride ("PVC") supplied by Empire Plastics. The PVC sheet was cut in the long grain direction. Beneath the PVC layer was a second layer of PVC of 20 inches x 25 inches x 10 mils, cut in the short grain direction. Under the short direction layer of the 10 mil PVC grain was a 20 inch x 25 inch x 2 mil sheet of Klockner ZE84 PVC cut in the long grain direction. A 21-inch x 26-inch sheet of transparent 2-mil polyester was placed over the Teslin® sheet to act as a release coating. This construction was placed between two polished stainless steel plates. • 21"x 26" x 30 mil. An identical coated Polyester / Teslin® sheet / PVC / PVC / PVC sheet was placed on top of a stainless steel plate of the existing construction. A polished metal plate was placed on the exposed polyester release coating. The pattern was repeated ten times more, in such a way that there were twelve multilayer folds pre-pressed in the stack. The resulting stack was placed between cushions cushions. The cushion pads are a combination of polyamide fiber and mechanical rubber, manufactured and supplied by Yamauchi Corporation, designed to more evenly distribute temperature and pressure during thermal lamination. The resulting stacking plus cushion pads were placed between two non-polished non-corrosive metal plates of 125 mils slightly larger. All this construction, which is referred to as a book, was put on a TMP lamination press, pre-heated to 300 ° F. The composite construction was laminated by compression at a pressure of 203 psi. The entire book was kept in this condition until the middle folds of the book reached a temperature of 261 ° F. The plates were then cooled, while they were still under the press, long enough to allow the same central folds to reach 100 ° F. After removing them from the press, the twelve composite sheets were all removed from the book. The twelve composite sheets were all topically treated with static protection on the PVC surface. The twelve finished composite sheets all had a good integrity; any attempt at delamination destroyed the Teslin® layer, which showed a good adhesive bond and no seams between the Teslin® and the PVC. ISO7910 ID-1 cards were punched using a PMC high die machine with the Teslin® surface facing the die cutting blade. The finished cards of each composite sheet had good integrity and a good flat "lat". The resulting cards were slightly blocked and did not demonstrate the required sliding performance. Example 13 The Wikoff SCW coating composition was applied 4890, manufactured and supplied by Wikoff Industries, 300 feet from a ZE84 2 mil PVC lockner sheet using a flexographic or gravure coating method. A single coating station was fixed with a 6 cm anilox roller and a non-textured rubber application roller. The coating feeding chamber was supplied from a coating maintenance tank and a pump. The continuous roll stock was spun through the equipment in such a way that the coated sheet was passed through a drying oven, with the coated surface facing the hot air source. The line speed was 200 fpm, the oven temperature was 105 ° C (220 ° F) and a single coating pass was applied. The coating composition was applied with a coating weight of approximately 6.1 mg / square inch. The resulting coated roll was converted to 20"x 25" sheets along the grain. Example 14 The 2 mil coated PVC sheet prepared as described in Example 13 was made into cards using the following procedure. A coated Tes-lin® sheet was placed on top of a 20 inch x 25 inch sheet of 0.10 inch polyvinyl chloride (PVC) supplied by Empire Plastics. The PVC sheet was cut in the long grain direction. Below the PVC layer was a second layer of PVC of 20 inches x 25 inches x 10 mils, cut in the short grain direction. Below the layer in the short direction of the 10-mil PVC grain was the 20-inch x 25-inch x 2-mil PVC sheet coated cut in the long grain direction, placed with the coated surface facing the other side of the grain. 10 mil PVC layer adjacent. A 21-inch x 26-inch sheet of transparent 2-mil polyester was placed over the Teslin® sheet to act as a release coating. This construction was placed between two polished 21"x 26" x 30 mil stainless steel plates. An identical top layer of treated Teslin® polyester / PVC / PVC / PVC sheet was placed on top of a stainless steel plate of the existing construction. A polished metal plate was placed over the exposed polyester release coating. The pattern was repeated ten times more, in such a way that there were twelve multilayer layers pre-pressed in the stack. The resulting stack was placed between cushions cushions. The cushion pads are a combination of polyamide fiber and mechanical rubber, manufactured and supplied by Ya-mauchi Corporation, designed to distribute more evenly temperature and pressure during thermal lamination. The resulting stack plus cushion pads was then placed between two non-polished, non-corrosive metal plates of .125 mils slightly larger. The whole of this construction, which is referred to as a book, was put on a TMP lamination press, preheated to 300 ° F. The composite construction was laminated by compression at a pressure of 203 psi. The entire book was kept in these conditions until the middle layers of the book reached a temperature of 261 ° F. The plates were then cooled, while they were still under the press, long enough to allow the same central layers to reach 100 ° F. After removing them from the press, the twelve composite sheets were all removed from the book. The twelve finished composite sheets all had a good integrity; any attempt at delamination destroyed the layer of Teslin®, which demonstrated a good adhesive bond and seamless between Teslin® and PVC. ISO7910 ID-1 cards were punched out from each of the 20-inch x 25-inch x 30.5-mil laminates. The finished cards of each composite sheet had good integrity and a good flat lat. The resulting cards demonstrated non-blocking behavior and required slip performance Friction force test method A card was fixed to a smooth flat base A second card was placed on top of the base card, with an offset of ½ inch over the longitudinal edge. The second card was attached to a force gauge through a cable and a pulley system. The cali-brador of force was attached to the moving arm of an instrument. A symmetrical weight was placed on the second card with the trailing edge of the weight centered and leveled with the trailing edge of the second card. The pair of cards was placed one (1) minute before the traction. The upper card was slid over the lower card approximately 1.5 inches and the maximum tensile force measured in the force gauge was recorded. The procedure was repeated five (5) times, each time with a different pair of cards. The mean, standard deviation and% coefficient of variation of the six measurements were calculated and given.

Sliding performance of cards Example 15 A coated Teslin® sheet was placed on top of a 20 inch x 25 inch liner of 0.10 inch polyvinyl chloride (PVC) supplied by Empire Plastics. The PVC sheet was cut in the long grain direction. Below the PVC layer was a second layer of PVC of 20 inches x 25 inches x 10 mils, cut in the short grain direction. Below the layer in the short direction of the 10-mil PVC grain was a 20-inch x 25-inch x 2-mil PVC sheet of Klockner ZE84 cut in the long grain direction. A 21-inch x 26-inch sheet of transparent 2-mil polyester was placed over the Teslin® sheet to act as a release liner. This construction was placed between two polished 21"x 26" x 30 mil stainless steel plates. An identical upper layer of polyester / treated Teslin® sheet / PVC / PVC / PVC was placed on top of a stainless steel plate of the existing construction. A polished metal plate was placed over the exposed polyester release coating. The pattern was repeated ten times more, in such a way that there were twelve multilayer layers pre-pressed in the stack. The resulting stack was placed between cushions cushions. The cushion pads are a combination of polyamide fiber and mechanical rubber, manufactured and supplied by Ya-mauchi Corporation, designed to more evenly distribute temperature and pressure during thermal lamination. The resulting stack plus buffer cushions were then placed between two non-polished, non-corrosive metal plates of 125 mils slightly larger. The whole of this construction, which is referred to as a book, was put on a TMP lamination press, preheated to 300 ° F. The composite construction was laminated by compression at a pressure of 203 psi. The entire book was kept in these conditions until the middle layers of the book reached a temperature of 261 ° F. The plates were then cooled, while they were still under the press, during the time sufficient to allow the same central layers to reach 100 ° F. After removing them from the press, the twelve composite sheets were all removed from the book. The twelve composite sheets were all topically treated with static protection on the PVC surface. The twelve finished composite blades all had a good integrity; any delamination attempt destroyed the Tes-lin® layer, which showed a good adhesive bond between the Teslin® and the PVC. ISO7910 ID-1 cards were punched out from each of the 20-inch x 25-inch x 30.5-mil laminates. The finished cards of each composite sheet had good integrity and a good flat lat. The resulting cards demonstrated non-blocking behavior and required slip performance. These cards were blocked, however, when placed in a stack of 100 cards after exposure to 24 hours, 85% RH, 55 ° C, under 1 kg load. Any attempt at delamination destroyed the Teslin® layer, which showed a good adhesive bond and no seams between the Teslin® and the PVC.

The coating composition is given in a descriptive format: Description of the coating: 40 active parts of CinFix RDF 30 active parts of PPG WC-71-2134 30 active parts of itcobond W240 · 12.5% total mixing solids. Example 16 A coating of Wikoff SCW 4890, manufactured and supplied by Wikoff Industries, was applied to 3,660 feet of Magne-tic Stripe Master Roll of 2 mils caliber, manufactured and supplied by JCP, using a flexographic / gravure coating method. A single coating station was equipped with a 5 bcm anilox roller and a non-textured rubber application roller. It was supplied to the coating feed chamber from a coating holding tank and a pump. The continuous stock of the roller was spun through the equipment in such a way that the surface containing the magnetic strip tape received the coating. The coated sheet was also passed through a drying oven, with the coated surface facing the hot air source. The speed of the line was 300 feet per minute, the oven temperature was 105 ° C (220 ° F) and a single coating pass was applied. A soft air curtain was directed towards the continuous coated sheet just before the winding station to eliminate creases and wrinkles. The coating was applied with a layer weight of approximately 5 mg / square inch. The resulting coated roll was converted into 25"x 20" sheets in the short grain direction. Example 17 The 2 mil coated Magnetic Strip Master Sheet prepared as described in Example 16 on cards was made using the following procedure. A sheet of coated Teslin® was placed on top of a 20 inch x 25 inch sheet of 0.10 inch polyvinyl chloride (PVC) supplied by Empire Plastics. The PVC sheet was cut in the long grain direction. Below the PVC layer was a second layer of 20 inches x 25 inches x 10 mils of PVC, cut along the grain. Below the layer along the 10-mil PVC grain was the 20-inch x 25-inch x 2-mil Magnetic Strip Master Sheet cut in the short grain direction, placed with the coated surface facing away from the grain. adjacent layer of PVC of 10 mils. A 21-inch x 26-inch sheet of transparent 2-mil polyester was placed on the Teslin® sheet to act as a release coating. This construction was placed between two 21"x 26" x 30 mil polished stainless steel metal plates. An identical coated Polyester / Teslin® sheet / PVC / PVC / Master Magnetic Strip Sheet was placed on top of a stainless steel plate of the existing construction. A polished metal plate was placed on top of the exposed polyester release liner. The pattern was repeated ten times more, in such a way that there were twelve multilayer folds pre-pressed in the stack. The resulting stack was placed between cushions cushions. The cushion pads are a combination of polyamide fiber and mechanical rubber, manufactured and supplied by Yamauchi Corporation, designed to more evenly distribute temperature and pressure during thermal lamination. The resulting stack plus cushion pads was then placed between two slightly polished, non-corroded, non-corrosive metal plates of 125 μl. All this construction, referred to as a book, was put on a TMP lamination press, preheated to a temperature of 300 ° F. The composite construction was laminated by compression at a pressure of 203 psi. The entire book was kept in these conditions until the layers in the middle of the book reached a temperature of 261 ° F. While it was still hot, the pressure of all the books was released for one minute and the pressure was then reintroduced. The plates were then cooled for sufficient time to allow the same central layers to reach 100 ° F. After removing them from the press, the twelve composite sheets were all removed from the book. The Mylar release liner was removed from the Teslin® sheet. The surface of the magnetic strip showed defects resulting from the printing of the Wikoff coating on the lamination plate. The twelve finished composite sheets had good integrity; any attempt at delamination resulted in the destruction of the Teslin® layer, which demonstrated a good adhesive bond and essentially no seams between the Teslin® and the PVC. 1SO7910 ID-1 cards were punched out from each of the composite sheets of 20 inches x 25 inches x 30.5 mils. The finished cards of each composite sheet had good integrity and a good flat lat. The cards proved to demonstrate non-blocking behavior and required slip performance. Example 18 - Thermal Lamination A sheet of TS 1000 (available from PPG Industries, Incorporated, under the trade name Teslin), which measured 8.5 x 11 inches, was cut from a master roll. The Teslin sheet was cut using four (4) passes per side. The coating composition used to coat the Teslin was prepared by first diluting an anionic polyurethane with 31% solids, sold under the trademark WitcoBond 234 (from Crompton Corporation, Greenwich, Connecti-cut), at 12.3% solids in a stainless steel mixing tank under high speed mixing with a head mixer. In a separate feed tank, a solution of 55% solids of a reacted polyamide amine with dimethylamine and epichlorohydrin (available under the trade name CinFix NF, from Stockhausen GmbH &Co., KG, Krefeld, Germany) was diluted. ) at 7.7% solids and was then added to the diluted dispersion of anionic polyurethane at a ratio of 50/50 by volume and the mixture was mixed for 15 minutes. The pH was adjusted to 5.0 +/- 0.5. The total resin solids of the mixture was 10%. The coating composition was applied to the Teslin sheet (10 mils thick) using flexographic re-dressing technology, which included two coating stations containing forced air drying ovens. Each coating station consisted of a coating feeding chamber, anilox roller and rubber roller. It was supplied to the coating feeding chamber from a coating maintenance tank and a pump. Only one coating station was used in the preparation of this material. The apparatus was equipped with an anilox roller of 7 bcm (trillion cubic microns), the line speed was 180 fpm (feet per minute) and the oven temperature was 105 ° C (220 ° F). Eight (8) passes per roll were made, corresponding to four (4) passes per surface. A printing test was then made on the sheet using an HP1220C color ink jet printer. The printed sheet was laminated using the following test method of lamination peel strength. The 8.5 x 11 inch sheet of Teslin was covered with a Sealtran 3/2 laminate film of 8.5 x 11 inches. A 2 x 11 inch strip of 20 Ib strand paper was placed along the center line (in the 11 inch direction) on the Teslin. The film to be studied was cut to 8.5 inches by 11 inches and placed directly on top of the aforementioned structure. The laminated sheet was cut into a piece of 4.25 inches by 11 inches. Strips (1 inch by 4.25 inches) were then cut using a JDC Precision Sample Cutter (Thwing Albert Instruments). Each strip was placed in a "lamination pocket" coated with silicone. The pocket was fed through a pocket laminator large enough to accommodate the pocket. The rolling roll temperature varied between 275 and 300 ° F (120-135 ° C). The laminated samples were then stored at room temperature for at least 24 hours before the debonding test. The lamination film was peeled back from the Teslin and placed in the upper jaw of a tensile meter. The lower portion was placed in the lower jaw of the traction meter. A barking of 180 ° was performed at 0.5 inch / minute with a sample rate of 4.0 pt / second. The results of the test showed that the initial resistance to barking was 9.6 pounds / inch and demonstrated that the resulting substrate retained its integrity after soaking in water for 24 hours.Example 19 In preparing a coating composition of the present invention, a 31% polydimethyldiallylammonium chloride sold under the trade name CinFix RDF, Stockhausen GmbH & Co. KG, Krefeld, Germany, 10% deionized water in a stainless steel or polyethylene mixing vessel with gentle agitation.

A coated Teslin sheet was placed on top of a 20-inch x 25-inch sheet of 0.10-inch polyvinyl chloride (PVC) supplied by Empire Plastics. The PVC sheet was cut in the long grain direction. Below the PVC layer was a second layer of 20 inches x 25 inches x 10 mils of PVC, cut in the short grain direction. Below the 10-mil PVC layer cut in the short grain direction, there was a 20-inch x 25-inch x 2-mil PVC sheet cut in the long grain direction. A 21-inch x 26-inch sheet of 2-mil clear polyester was placed on the Teslin sheet to act as a release liner. This construction was placed between two 21"x 26" x 30 mil polished stainless steel metal plates. An identical coated Polyester / Teslin foil / PVC / PVC / PVC sheet was placed on top of a stainless steel plate of the existing construction. A polished metal plate was placed on top of the exposed polyester release liner. The pattern was repeated ten times in such a way that there were twelve multilayer layers pre-pressed in the stack. The resulting stack was placed between cushions cushions. The cushion pads are a combination of polyamide fiber and mechanical rubber, manufactured and supplied by Yamauchi Corporation, designed to more evenly distribute temperature and pressure during thermal lamination. The resulting stack plus cushion pads were then placed between two 125 mil unpolished non-corrosive metal plates. All this construction, referred to as a book, was put on a TMP lamination press, preheated to 300 ° F. The composite construction was laminated by compression at a pressure of 203 psi for 18 minutes at a temperature of 300 ° F. While they were still under pressure, the plates were cooled to less than 100 ° F, which took approximately 19 minutes. After removing them from the press, all twelve composite sheets of the book were removed. All twelve finished composite sheets had good integrity; any attempt at delamination destroyed the Teslin layer, which showed a good adhesive bond and no seams between the Teslin and the PVC. ISO7910 ID-1 cards were punched out from each of the 20-inch x 25-inch x 30.5-millimeter composite sheets. The finished cards of each composite sheet had good integrity and a good flat lat. Any attempt at delamination destroyed the Teslin layer, which showed a good adhesive bond and no seams between the Teslin and the PVC. This previous example was also carried out using Teslin SP1000, which produced the same results as the Teslin TS1000. Example 23 Composite sheets manufactured according to Example 19 were soaked individually in deionized water for 15 minutes and then allowed to air dry for 24 hours. ISO7910 ID-1 cards were punched out from each of the composite sheets of 20 inches x 25 inches x 30.5 mils. The finished cards of each composite sheet had good integrity and a good flat lat. Any attempt of delamination destroyed the Teslin layer, which shows a good adhesive bond between the Teslin and the PVC. The resulting conditioned cards demonstrated easier separation of a stack and sliding characteristics compared to the non-conditioned version.
