Definitions

  • the present invention relates to heads for use in inkjet printing, and more particularly to heads for use in inkjet printing, having improved resistance to inks containing acetylene glycol, glycol ether or the like.
  • a printing head for use in an ink jet printing method comprises an orifice from which a printing ink is jetted; an ink channel, connected to the orifice, having a portion at which energy is applied to a printing ink so that the ink can be jetted; and an ink container in which a printing ink to be supplied to the ink channel is stored.
  • a method for producing such a head for use in inkjet printing a method in which an ink channel is formed by providing a minute groove in a substrate made of glass, a metal or the like by means of, for instance, cutting or etching, and by attaching thereto another substrate.
  • An object of the present invention is to provide a printing head comprising an activation-energy-ray-hardening resin, having resistance to highly efficient ink compositions containing acetylene glycol or the like.
  • a printing head for use in ink jet printing comprising an ink-jetting nozzle and an ink channel connected to the ink-jetting nozzle,
  • a printing head for use in inkjet printing comprising an ink-jetting nozzle and an ink channel connected to the ink-jetting nozzle,
  • a printing head for use in ink jet printing comprising an ink-jetting nozzle and an ink channel connected to the ink-jetting nozzle,
  • the present invention also provides a method for producing any one of the above printing heads, comprising the steps of:
  • an activation-energy-ray-hardening resin means a resin having a property that it is hardened due to polymerization or the like when irradiated with active energy rays, for instance, visible light, ultraviolet rays or electron beams.
  • Resins having such a property have already been known, and can be utilized in the present invention. Many of these resins contain molecules having an ethylenically unsaturated bond or a functional group such as an epoxy group, and polymerization between the molecules proceeds through the functional group when activation energy rays are applied thereto. The resins are thus hardened due to this polymerization.
  • the resin which can be utilized in the present invention include those resins which contain a monomer having an ethylenically unsaturated bond.
  • a monomer include unsaturated monomers containing a carboxyl group, such as acrylic acid and methacrylic acid; unsaturated monomers containing a glycidyl group, such as glycidylacrylate and glycidylmethacrylate; hydroxyacryl esters of acrylic acid or methacrylic acid, such as hydroxyethylacrylate, hydroxyethylmethacrylate, hydroxypropylacrylate and hydroxypropylmethacrylate; and monomers having one or more ethylenically unsaturated bond, such as a monoester of acrylic acid or methacrylic acid and polyethylene glycol or polypropylene glycol.
  • Examples of another resin which can be utilized in the present invention include those resins which contain an epoxy group in the structure thereof.
  • Specific examples of such a resin include epoxy resins such as of a bisphenol Atype, of a novolak type, and of an alicyclic type.
  • bisphenol A, bisphenol F, tetrahydrox- yphenylmethane tetraglycidyl ether, resorcinol glycidyl ether and glycerol triglycidyl ether can also be utilized.
  • a commercially available resin can also be utilized in the present invention.
  • Preferred examples of such a resin include “Photec SR-1300G”, “Photec SR-3000", “Photec SR-2200G” and “Photec SR-2300G” (manufactured by Hitachi Chemical Co., Ltd.); “Ohdil PR-150”, “Ohdil PR-155", “Ohdil SE-200” and “Ohdil SP-700” (manufactured by Tokyo Ohka Kogyo Co., Ltd.); and “A-400", “FH 5100” and “FH 6100” (manufactured by Fuji Hunt Electronics Technology Co., Ltd.).
  • Fig. 1 is a partial cross-sectional view of a printing head of the present invention.
  • first substrate 11 and second substrate 12 which are made of glass, a resin, or a metal such as nickel or stainless steel are provided, and between these substrates are formed layers 13,14 and 15 of an activation-energy-ray-hardening resin.
  • ink channel 16 and pressure chamber 17, which are connected to each other.
  • the ink channel 16 is connected to an ink-supplying part (not illustrated), and an ink composition is thus supplied to the ink channel.
  • Pressure-generating means 18 such as a piezoelectric element or an exothermic element is provided to the pressure chamber 17 so as to pressurize the ink composition in the pressure chamber 17.
  • a droplet of the ink is jetted from ink nozzle 19 by the pressure generated by this pressure-generating means 18.
  • the printing head having the above structure may be produced by the following method.
  • the first layer 13 of an activation-energy-ray-hardening resin is firstly formed on the first substrate 11. This resin layer is then subjected to desired-pattern-wise exposure, for example, by using a pattern mask or by means of scanning exposure (Fig. 2(a)). The unexposed, unhardened area of the resin layer is removed by using, for example, a solvent to form a groove which will be an ink channel (This is a so called a developing process) (Fig. 2(b)). If necessary, a second layer of an activation-energy-ray-hardening resin (layer 15 in Fig. 2(b)) can be provided on the first layer 13 in the same way, and a groove can also be formed therein.
  • the layer 15 can be formed by forming a layer of an activation-energy-ray-hardening resin on the layer 13 which has been hardened and developed, subjecting the layer to desired-pattern-wise exposure, and then removing unhardened area of the layer to form the layer 15. A groove which will finally be an ink channel is thus formed on the first substrate.
  • the second substrate 12 is attached to the first substrate 11 which is provided with the groove for an ink channel. It is noted that the second substrate 12 may also be one having thereon a groove of a desired pattern provided by using an activation-energy-ray-hardening resin in the same manner as in the first substrate (Fig. 2(c)).

  • the two substrates are firstly faced each other as shown in Fig. 2(c).
  • the attachment of the substrates may be conducted by using an adhesive agent. However, according to the preferred embodiment of the present invention, they are attached to each other without using any adhesive agent.
  • the resin layer provided on the first substrate 11 (and the resin layer on the second substrate 12 if provided) is hardened to such a degree that the resin layer can have minimum hardness required to form a groove therein.
  • the two substrates are then brought into close contact with each other with pressure, and heat and/or activation energy rays are applied thereto to further harden the resin.
  • the two substrates can thus be firmly attached to each other.
  • activation energy rays are to be applied from the outside of the first and/or second substrates (Fig. 2(d)).
  • the activation energy rays are required to have high transmission like electron beams when the substrates are not transparent.
  • the intensity of electron beams to be applied may be unlimited, when electron beams with very high intensity are applied, there is a possibility that the substrates are broken. It is therefore preferable to use an electron beam generator having an accelerating voltage of approximately 150 to 300 KeV.
  • the method using no adhesive agent is very suitable for the production of excellent printing heads, because an adhesive agent may be clog an ink channel during the production process of printing heads.

  • the values Pf and Pi can be obtained, for example, in the following manner.
  • an epoxy group shows an absorption peak in the range of approximately 900 to 920 cm- 1 . Therefore, as in the case of the value T, the values Pi and Pf can be respectively obtained by calculating the ratios of the absor- sayes attributed to an epoxy group in the resin before and after hardened to the absorbance attributed to a functional group which undergoes no change in its structure before and after the resin is hardened by exposure.
