Definitions

  • the present invention relates to an ink for forming a receiving layer and products using the same.
  • a receiving layer has been printed or coated on a substrate to get faster absorption of an ink and to lessen smears when substrates such as paper, film, and board are printed with ink-jets.
  • An ink for forming a receiving layer is made by dissolving a water-soluble polymer in an aqueous medium and by adding a filler such as silica, alumina, and aluminium hydroxide.
  • US 5,270,100 discloses substrates couted with phosphorescent pigment for application of coloured translucent media
  • US 5,279,058 discloses a lamina with a matt phosphorescent pigment coating so that indelible writing can be made thereon using a writing instrument.
  • the object of the present invention is to provide an ink for forming a receiving layer which contains a novel agent to enhance the receiving property.
  • Another object of the present invention is to provide both a ink for forming a receiving layer that contains a novel agent to enhance the receiving property having other functions beside of the properties to enhance the receiving property which are usually given by traditional materials such as silica, Alumina, Aluminium hydroxide and water absobing organic material and a product in which said ink is used.
  • the present invention provides both an ink for forming a receiving layer that contains an agent to enhance a property to receive an ink-jet ink and to confer a phosphorescent property, and a product in which said ink is used.
  • the present invention provides an ink for forming a receiving layer for an ink-jet ink, said ink containing a phosphorescent pigment to enhance the receiving property.
  • the present invention also provides a product to receive an ink-jet ink, said product being printed or coated with an ink for forming a receiving layer containing a phosphorescent pigment to enhance the receiving property on a substrate, and a product made by printing with an ink-jet ink on said product to receive said ink.
  • Phosphorescent pigments to be added to enhance the receiving property include commercial phosphorescent pigments such as an N luminescence phosphorescent pigment and an S luminescence phosphorescent pigment.
  • a phosphorescent pigment with a particle size of 0.5-50 ⁇ m is used; preferably 5-35 ⁇ m; most preferably 8-25 ⁇ m, in the inks of the present invention.
  • Using too small particle size tends to reduce the effect to enhance receiving property and the phosphorescent property.
  • using too big particle size tends to give rough pictures in ink-jet printing and lower quality of image-printing.
  • the amount of the phosphorescent pigment to be added in an ink for forming a receiving layer according to the present invention is 5-120 weight% by weight, preferably 15-90 weight% by weight ink vehicle, in the inks of the present invention.
  • An agent to enhance the receiving property may be used in combination of a phosphorescent pigment and known agents to enhance the receiving property such as water-absorptive organic material, silica, alumina, and aluminium hydroxide. Combinations of a phosphorescent pigment and water-absorptive organic materials such as protein powder, cellulose powder, and water-absorbing polymer powder give excellent results.
  • a preferable binder that is used in an ink for forming a receiving layer according to the present invention is a hydrophilic polymer.
  • a hydrophilic polymer non-water-soluble polymers having hydrophilic groups that reduce a water-repelling property are preferably used as well as water-soluble polymers.
  • Water-soluble monomers and water-soluble monomers to which various oligomers or polymers were dissolved can be preferably used as a binder in curable inks such as a UV-curable ink.
  • Products for receiving ink-jet inks can be produced by printing or coating on various substrates.
  • Said printing or coating include screen printing, gravure printing, flexography, typography, spray coating, and roll coating.
  • Printing with solvent-based inks accompanies solvent-drying; printing with UV-curable inks UV-exposure, etc.
  • Thickness of a printed layer for receiving ink-jet inks is 1-100 ⁇ m in general, preferably 5-50 ⁇ m. Therefore, a layer for receiving ink-jet inks can be printed preferably by methods such as screen printing.
  • Synthetic polymers are preferably used as the substrate for products for receiving.
  • Said synthetic polymers include polycarbonate, polyvinylchloride, polyester, polyolefin, ABS resin, acryl resin, and setting resin. Although these resins have low ink-jet ink-receiving properties in general, products for receiving having both very excellent ink-jet ink-receiving and phosphorescent properties can be produced by printing with the inks for forming a receiving layer according to the present invention.
  • the synthetic resin substrate is an information-recording medium
  • products with extremely high additional value can be produced.
  • information-recording media such as compact discs according to the present invention have both ink-jet ink-receiving and phosphorescent properties, those media have such an advantages that various designs as well as displays of usage and properties of said disc can be printed and be seen even in the dark.
  • the present invention confers ink-jet ink-receiving and phosphorescent properties to inks and enables one to read in the dark and to enhance an ink-jet ink-receiving property.
  • Ink I for forming a receiving layer according to the present invention (Embodiment 1): N luminescence phosphorescent pigment (average particle size 15 ⁇ m) 15.0 wt% Water-absorbing organic filler 15.0 wt% Photo-reactive acryl oligomer 20.0 wt% Photo-reactive monomer 43.0 wt% Photo initiator 5.0 wt% Additive 2.0 wt% Ink II for forming a receiving layer according to the present invention(Embodiment 2) N luminescence phosphorescent pigment (average particle size 15 ⁇ m) 30.0 wt% Photo-reactive acryl oligomer 20.0 wt% Photo-reactive monomer 43.0 wt% Photo initiator 5.0 wt% Additive 2.0 wt% Ink III for control: Photo-reactive acryl oligomer 45.0 wt% Photo-reactive monomer 48.0 wt%
  • CD-R substrates were screen-printed at 300 mesh with inks of the embodiments 1 and 2 and the control, and inks were cured by exposure to UV-light to give products with a film thickness of 15 ⁇ m.
  • Resulting substrates were printed with ink-jet printer A (Canon Co., Ltd.) and ink-jet printer B (Epson Co., Ltd.). Printing properties of the substrates were observed both in the light and in the dark. The result of the observation are summarized in Table I (Symbols: o ⁇ , excellent; ⁇ , very good; ⁇ , not good).
  • ink I When ink I was used, the printing property was excellent: the disc was seen and printed letters can be read in the dark. When ink II was used, the printing property was very good: the disc was seen and printed letters can be read clearly in the dark. When ink III was used, however, the printing property was not good: the disc was not seen and printed letters can not be read in the dark.
