Definitions
- This invention relates to pressure-sensitive record sheet material including a base record material sheet having at least on one surface a subcoating of latex material over which is coated a layer of printing-liquid-containing pressure-rupturable microcapsules. This sheet is used capsule-coated side against a sheet sensitized to react with liquid released by imaging printing pressure made against the capsule-coated sheet to yield a distinctively-colored image.
- the latex coating serves the purpose of cushioning the capsules against rupture by casual pressure occurring in handling, rolling, and stacking of the sheet material, and assists in the transfer of capsule-yielded liquid to the sensitized sheet by resisting wetting of the capsule-bearing base sheet by the liquid released from the ruptured capsules.
- This invention relates to pressure-sensitive record sheet material including a base record material sheet having at least on one surface a subcoating of latex material over which is coated a layer of printing-1iquid-containing pressure-rupturable microcapsules.
- This sheet is used capsulecoated side against a sheet sensitized to react with liquid released by imaging printing pressure made against the capsule-coated sheet to yield a distinctively-colored image.
- the latex coating serves the purpose of cushioning the capsules against ruputre by casual pressure occurring in handling, rolling, and stacking of the sheet material, and assists in the transfer of capsule-yielded liquid to the sensitized sheet by resisting wetting of the capsule-bearing base sheet by the liquid released from the ruptured capsules.
- the present invention was conceived and developed to control the handling smudge problems which exist Where a capsule-coated sheet is placed against a markreeciving sheet for winding or storage.
- the smudge is especially pronounced in a paper sheet sensitized with a small amount of acidic-reacting oil-soluble phenolic polymeric material deposited from a solution thereof that leaves, by drying, a highly-sensitive reactive surface film which merely clothes the separate paper fibers, leaving the gross paper structure porous.
- Such highly-sensitized paper is disclosed in Canadian Pat. No. 768,039, dated Sept. 26, 1967.
- the capsule-bearing sheet of this invention usually is paper of the record material class
- any record sheet material can be used as the base to which the latex subcoating may be applied.
- a ground coating of film-forming hydrophilic colloid material such as polyvinyl alcohol, may be applied and then the subcoating of liquid latex applied on top to economize on the materials which otherwise would penetrate the sheet and whose utility would thus be lost.
- the ground coating of polyvinyl alcohol may be applied from a water solution in an amount that will yield a dried weight of 1.1 pounds per ream (25 x 38 inches X 500 sheets) of paper, and the latex is applied thereover as a water dispersion to yield a dried coating weight of 0.5 pound per ream of the same dimension.
- the ground coating is not used, more of the latex material may be applied, the amounts applied being balanced to suit the economic requirements; that is to say, if the base paper sheet is of such quality that the ground coating of hydraphilic colloid is not necessary, then the optimum condition may be attained by using the latex coating by itself. This optimum condition is tested by subjecting the finished sheet to pressure contact against a receiving paper sheet sensitized with 0.25 pound per specified ream of an eligible acidic phenolic resin.
- the improvement factor test is performed first by the pressures applied by a standard typewriter to estimate the intensity of print, which is directly related to the amount of released capsule liquid that is transferred to the phenolic-sensitized sheet, and, secondly, by smudge tests including a static weight test and a frictional smudge test.
- the readings of prints made by a typewriter and of smudges produced under static and frictional load are measured as a number Typewriter, Frictional Static,
- the latex material which has proven best and easiest to work with is taken from the synthetic class comprising ethylene-vinyl acetate copolymers, polyvinyl chloride, and polyvinylidene chloride.
- hydrophilic film formers found desirable to use for ease of handling and low cost are the mentioned polyvinyl alcohol and ammonium complexes of casein.
- microcapsules found most useful in practicing the invention preferably are those single oil drop nonclustering kind that are made according to the teaching of Isidore L. Yurkowitz which is disclosed in South African Pat. No. 3,763/67, in which the preferred example is disclosed as follows:
- This example concerns the encapsulation of an oil drop having a colorless dye dissolved therein, the capsule wall being formed of a gelatin-gum arabic-polyvinyl methyl ether-maleic anhydride (PVM/MA) copolymer material.
- PVM/MA gelatin-gum arabic-polyvinyl methyl ether-maleic anhydride
- PVM/ MA Polyvinylmethylether-maleic anhydride copolymer solution.Twenty-three grams of the PVM/MA (such as Gantrez An sold by General Aniline and Film Corporation, New York, N.Y., United States of America, which has a specific viscosity of 1.0 to 1.4 in 1 percent, by weight, ethylmethylketone solution at 25 degrees centigrade, a softening point of 200 to 225 degrees centigrade, and a specific gravity of 1.37) was dissolved in 460 grams of distilled water by being stirred at a temperature of 90 degrees centigrade until the liquid was clear.
- PVM/ MA Polyvinylmethylether-maleic anhydride
- Phase separation was induced by adding, at a constant rate over ten to fifteen minutes, 13.5 milliliters of a mixture composed of 9 milliliters of solution (IV) and 4.5 milliliters of 14.7 percent, by weight, aqueous solution of acetic acid.
- the phase separation step was comp eted by addition of 3 milliliters more of 14.7 percent, by weight, aqueous acetic acid and subsequent chilling in an ice bath to below 12 degrees centigrade. While the system was at a temperature below 12 degrees centigrade, 7.5 milliliters of 25 percent, by weight, aqueous glutaraldehyde (pentanedial) was added.
- the capsule product had a particle size range with a peak at 3.25 microns, 83.8 percent of the particles having diameters of 5.17 microns or less. Inspection of the capsules showed a predominance of single-core entities.
- the capsules made by the foregoing procedure, as indicated, were supplied with the colorless chromogenic materials crystal violet lactone and benzoyl leuco methylene blue and were especially made for color development on the acidic mineral attapulgite, which colors the crystal violet lactone blue by an electron donor-acceptor adsorption reaction and colors the benzoyl leuco methylene a blue color by a reaction involving first a hydrolysis fol lowed automatically by an oxidation-reduction reaction.
- the capsule-coated sheet of this invention involves the coloration of the capsule-liquid-receiving sheet by reaction of the capsule contents with acidic phenolic polymeric material which has no coloring activity with respect to benzoyl leuco methylene blue, the latter can be omitted from the capsule liquid contents of the Yurko- Witz type or replaced by an equivalent amount of crystal violet lactone.
- a 30-pounds-per-ream bond sheet of printing paper is coated in any conventional manner with a 5 percent, by weight, concentration of polyvinyl alcohol in water, the polyvinyl alcohol being of 99-100 mole percent hydrolysis, and the aqueous solution of polyvinyl alcohol is applied in amount to yield a dried coating of the specified 1.1 pounds/ream.
- concentration of polyvinyl alcohol in water the polyvinyl alcohol being of 99-100 mole percent hydrolysis
- the aqueous solution of polyvinyl alcohol is applied in amount to yield a dried coating of the specified 1.1 pounds/ream.
- wastage of latex prevails because of paper porosity
- the base coating which resists penetration of the latex, can be used to reduce the total cost of the system.
- the pounds per ream of base coat used is not a figure that is precisely relevant to the function of the base coating and may vary according to the result desired.
- the latex coating is applied as a water dispersion and preferably is of the ethylene-vinyl acetate copolymer type, for economic reasons alone, there being not much choice of one of the specified class over the others as to performance. All latex film coatings of the type specified perform the cushioning function for the capsules coated thereover, but some other latex emulsions have an undesirable efiect on the capsule walls in respect to the ability of the walls to contain liquid contents.
- the named class of latexes performed in an exemplary manner in respect to their inertness as to aifecting the retention of the capsule contents within the capsule wall material.
- latexes may be empirically tested by coating capsules over them and, when dried, trying to extract the capsule contents by a solvent such as toluene--the ineligible latexes being ascertained by the degree of capsule contents extracted.
- the ethylene-vinyl acetate copolymer results only in a rise of about four percent increase in capsule con tent extraction and, thus, is well within the limits of ten percent. Latex coatings rating lower than ten percent increase will be deemed eligible for the purpose of practicing this invention even though not specifically named.
- a latex coating having a dried weight of .5 pound per specified ream works admirably with an overcoating of the dried capsules specified.
- the capsule coating (dried) should contain about one pound per specified ream of liquid capsule contents when the capsules are made according to the Yurkowitz procedure disclosed in detail above.
- Said capsules are composed of about to percent liquid contents, of which only between three and four percent is colorless colorable material.
- the capsules are applied as a liquid slurry of capsules having about 25 percent solids, in water, of which solids 40 percent is capsules and 60 percent is protective solid particles, such as the cellulose fibers mentioned above.
- a pressure-sensitive record member comprising a base sheet of paper, a thin latex film layer on a surface of the sheet, and a layer of liquid-containing pressurerupturable microcapsules cushioned by and overlaying the latex film layer, the latex film layer protecting the microcapsules from rupture by casual forces of friction, winding, and stacking but permitting imaging pattern pressure of writing or printing instruments to cause a rupture of correspondingly pressured capsules, and at the same time aiding the transfer of liquid released from the microcapsules to a receiving sheet, and wherein the latex film layer is a dried coat of an aqueous dispersion of polymer material chosen by empirical test such that a toluene-extraction of the liquid contents of the microcapsules on the record member is no greater than ten percent higher than the toluene-extraction of the liquid contents of the microcapsules on a similar record member having no thin latex film layer thereon.
- the record member of claim 1 having a ground coating of film-forming hydrophilic colloid material between the base sheet and the thin latex film layer.
- a pressure-sensitive record member comprising a base sheet of paper, a thin latex film layer on a surface of the sheet, and a layer of liquid-containing pressurerupturable microcapsules cushioned by and overlaying the latex film layer, the latex film layer protecting the microcapsules from rupture by casual forces of friction, winding, and stacking but permitting imaging pattern pressure of writing or printing instruments to cause a rupture of correspondingly pressured capsules, and at the same time aiding the transfer of liquid released from the microcapsules to a receiving sheet, and wherein said thin latex film layer is a dried coat of an aqueous dispersion of polymer material selected from the group consisting of ethylene-vinyl acetate copolymer, polyvinyl chloride, and polyvinylidene chloride.
