Definitions

  • Transparent recording sheets are generally prepared by the application, on a transparent film base, of various recording processes, such as handwriting with a pen, reproducing by electronic photography, heat transfer by flashlight (thermographic practice), or printing by a printer (hereinafter referred to as the means of printing).
  • the fixing ability depends for its quality on the multiplying effect of the drying ability of the ink used and the ink-absorbing ability of the recording material surface.
  • the film surface is therefor treated to raise the ink-absorbing ability, for which purpose the surface is, for example, provided with a coat having fine holes.
  • Application of this method involves the problem of causing the film to be less transparent.
  • the representative forms of printers in the means of printing include the ink jet type or the impact type which latter includes wire dot printers or type printers.
  • the printing function is greatly affected by the physical properties of inks.
  • inks composed largely of low-boiling solvents cannot be used for ink ribbons of the impact application type because the inks need to be retained in an undried state almost permanently. Therefore, the solvents which are included in the composition of inks used for the means of printing must be high-boiling. Consequently, the inks themselves are extremely poor in drying ability.
  • any recording effected on the surface of a conventional transparent film with such inks proves extremely poor in taking capacity and hardly usable for commercial applications.
  • the remarkably increased use of CAD systems, word processors, etc. has given rise to strong wishes for transparent recording media by the means of printing and to corresponding requirements for transparent materials capable of recording with these means of printing.
  • the present invention offers transparent recording sheets which, by the means of printing such as word processors, employing inks whose composition includes high-boiling solvents, are capable of printing characters, figures, etc., with a good fixing ability while retaining an excellent transparency.
  • excellent performance in particular, is the color transparent recording sheet multicolor-printed with an ink ribbon whose ink composition includes a coloring agent; the sheet, for example, becomes a projection original of highly excellent performance when lit with an overhead projector.
  • the method according to the present invention for preparing an ink receptive transparent recording sheet to be used as printing films, overhead films and the like comprising providing at least one side of a transparent base sheet material with a transparent surface coat which consists of natural resin derivatives, high polymer derivatives or copolymer resins, and which dissolves or swells with a high-boiling solvent contained in an ink when applied to the recording sheet, wherein the solubility in the high-boiling ink solvent of the resin of the coating is higher than that of the resin contained in the ink.
  • the solubility in high-boiling solvents, of resins contained in the inks has been made lower than that of resins contained in the surface coats of transparent recording sheets.
  • the object of the present invention can be accomplished without qualifying or limiting the high-boiling-solvent and surface-coat materials.
  • solvents indicated by HO(C n H 2n O) m H (m being an integer of 2 to 7, n of 2 or 3) or HO(CpH40)a(C3H60)bH(7 a a + b 2, a and b being integers ⁇ 1) have been selected as high-boiling solvents to be contained in the inks, and surface coats formed on the transparent recording sheets which coats dissolve or swell upon contact with said solvents.
  • the high-boiling solvents indicated by the general formulas HO(C n H 2 n 0) m H or HO(C 2 H 4 0) a (CsHsO) b H (7s;a + b ⁇ 2; a, b each being integerss 1) are highly excellent solvents to supersede non- drying oils, including mineral oils, oleic acid, etc.; the inks composed by using these solvents claim excellent physical properties as special inks (e.g. inks for ink ribbons) in the means of printing, including the ink jet process or the impact process.
  • the coating materials in the present invention it is possible to use natural resins, such as shellac, resins which swell or dissolve in the high-boiling solvents mentioned before, such as cellulose acetate, cellulose nitrate, polyvinyl alcohol, and ployacrylamide, high polymer derivatives denatured through partial introduction of polar radicals, such as -COO-NH 4 + , -COO-M + , -NH 4 .HCI, and -OH, so that they may be caused to swell or dissolve in the high-boiling solvents mentioned before, or copolymer resins whose compositions include at least the monomers which constitute resins swelling or dissolving in the above-mentioned high-boiling solvents, and derivatives of such resins.
  • natural resins such as shellac
  • resins which swell or dissolve in the high-boiling solvents mentioned before such as cellulose acetate, cellulose nitrate, polyvinyl alcohol, and
  • transparent base materials used in the present invention mention may be made of transparent synthetic resin film, transparent paper, etc.; the higher their transparency, the better, and they should preferably have a total luminous transmittance of over 90%.
  • these tranparent base materials have a thickness selected according to their intended uses; as a rule they preferably should be 25 ⁇ m to 180 ⁇ m thick for recording characters or figures by the means of printing.
  • the resign ingredients A and B need to be a simplex component; they may be a mixture of two or more resin ingredients, or other surface-active agents, such as penetrants, or plasticizers, may be added.
  • resin ingredients A and B when, for example, aromatic hydrocarbons, including triethyl benzene and aromatic naphtha, are used for high-boiling solvents, styrene resins and chlorinated paraffins are desirable choices since they are highly soluble.
  • cellulose base resins including cellulose acetate, cellulose butyrate, cellulose acetate butyrate, and nitrocellulose are desirable for the resin ingredient B.
  • the resin ingredients A and B can be selected by taking separate advantage of the fact that the solubility of these cellulose-base resins in cellosolve-base or ester-acetate-base solvents varies with differences in molecular weight or in the degree of esterification.
  • nitrocellulose resins When nitrocellulose resins are to be used, for example, their difference in solubility due to molecular weight is utilized to select nitrocellulose resins of 1/2- to 1/4-second viscosity for the resin ingredient A and those of 1/8- to 1/64-second viscosity for the resin ingredient B. Also, when polyethylene glycol base high-boiling solvents are to be used, then poly vinyl alcohol, polyacrylamide, and other comparable resins, or acrylic resins, can be used for the resin ingredient B by transforming them into more soluble resins with the introduction of polar radicals, such as -COO-NH 4 + , -COO-M + , -NH 4 -HC1, and -OH.
  • polar radicals such as -COO-NH 4 + , -COO-M + , -NH 4 -HC1, and -OH.
  • an ink composition 1-1 for ink ribbons the following substances were mixed, and using a red ink dispersed with a 3-roll mill, an ink ribbon with a controlled ink deposition rate of 15 g/m 2 was prepared:
  • an organic-solvent-base paint composed of the following was prepared as a surface coating composition S-1 for a biaxially-extended polyester film of 100llm thickness, applied to one side of the film, and dried, thereby producing a transparent recording sheet with a coating thickness of 3 ⁇ m and a total luminous transmittance of 93%:
  • This recording sheet was printed with a wire dot printer, using the ink ribbon prepared before; the ink completely took in about 5 seconds after printing, and prints were obtained which gave no ink erasure even when rubbed with the finger or something.
  • the printed sheet was lit with an overhead projector, and a distinct red image projection obtained.
  • sheets of untreated 100 ⁇ m biaxially-extended polyester film were equally printed with the ink ribbon used in the invention and conventional ink ribbon; the sheets proved quite unserviceable as the ink readily came off the printed surface when rubbed with the finger or something, at the end of 5 minutes when the former ribbon was used and even at the end of a week when the latter ribbon was used.
  • Example 1 The following ink composition 1-2 was used to prepare an ink ribbon corresponding to Example 1:
  • an organic solvent base paint of the following surface coating composition S-2 was applied with a wire bar to one side of a 100 ⁇ m biaxially-extended polyester resin film preprimed for increased adherence, and dried, thus preparing a transparent recording sheet with a coating thickness of 4 ⁇ m and a total luminous transmittance of 92%:
  • This recording sheet was printed with a wire dot printer, using said ink ribbon; the ink completely took in about 10 seconds after printing, and prints were obtained which gave no ink erasure even when rubbed with the finger or something.
  • the printed sheet was lit with an overhead projector, and a distinct blue image projection obtained.
  • the transparent recording sheets obtained in the above Examples 3 and 4 were printed with a wire dot printer, using an ink ribbon charged with an ink of the following composition 1-3 so as to provide a deposition rate of 15 g/m 2 ; both sheets showed a highly excellent fixing ability of characters or figures, and when lit with an overhead projector, gave distinct blue images:
  • the transparent recording sheets of the invention have proved to offer an unimpaired transparency and also an excellent fixing ability of printed ink.
  • a transparent recording sheet was obtained by depositing a coat (formed by a wire bar process so as to be 7 ⁇ m thick) of the following composition S-5 on a preprimed side of a 100 ⁇ m thick biaxially-extended polyester film.
  • Example 5 and Example 2 may be compared in terms of apparent drying time as shown in the table below, which tells how quick is the drying speed of printing on the transparent recording sheets specified in the invention.
