Definitions

  • the invention relates to a recording sheet for overhead projection (OHP) or as a Blueing copy, which is suitable for the ink-jet recording method.
  • OHP overhead projection
  • Blueing copy which is suitable for the ink-jet recording method.
  • a transparent polymer film for example a polyester film, has hitherto been used as the recording material for OHP, the recording image being obtained by writing with various inks, application of toner, application of a thermosensitive foam-forming recording material, etc.
  • OHP film recordings obtained by the ink-jet recording process have the disadvantages that the drying time is too long due to the low ink absorption of the carrier material, or the image is transferred in the non-dry state and therefore the image runs on machine contact, is erased and contaminated.
  • Synthetic resins with good water absorption capacity are known. They are synthetic resins from the starch series (for example hydrolyzed acrylonitrile polymers, acrylic acid graft polymers) and synthetic resins from the series of synthetic resins (for example polymers of the polyvinyl series, polymers of the polyacrylic acid series, polymers of the polyethylene oxide series).
  • starch series for example hydrolyzed acrylonitrile polymers, acrylic acid graft polymers
  • synthetic resins from the series of synthetic resins for example polymers of the polyvinyl series, polymers of the polyacrylic acid series, polymers of the polyethylene oxide series.
  • a recording sheet for ink jet recorders with a transparent support is known, on which there is an ink acceptor layer made of polyvinylpyrrolidone and silica gel.
  • the invention is based on the object of creating a recording sheet for inkjet recorders in which even multicolored recordings have neither bleeding nor bleeding and a superior image density and practically sufficient transparency.
  • a recording sheet for inkjet recorders which is suitable for overhead projection (OHP) or as a Blueing copy and which comprises an ink acceptor layer which is applied to a transparent or semi-transparent support material and which comprises a synthetic resin which is soluble in an organic solvent with high water absorption capacity.
  • the synthetic resin is a modified polyethylene oxide which can be obtained by reaction between a mono- or polyisocyanate compound and an ethylene oxide polymer or copolymer with an average molecular weight of at least 100,000 in a weight ratio of 0.015-5 to 100 and a water absorption capacity of 1- 50 times its weight when impregnated with demineralized water at 25 ° C for 30 minutes.
  • the polyethylene oxide modified according to the invention and also the preferred polymers according to the invention, which can be used as a further constituent, such as polyvinyl butyral and polyvinyl acetate, are compounds which are sufficiently readily soluble in organic solvents.
  • the synthetic resins of the invention are soluble in organic solvents, they are applied as a coating agent dissolved in the solvent, so that a coating with a superior transparency can be obtained.
  • the synthetic resins according to the invention must have a high water absorption capacity, with a view to a satisfactory drying capacity of the ink and a satisfactory water resistance of the image, the synthetic resin according to the invention at 30 minutes impregnation with ion exchange water of 25 ° C. has a water absorption capacity of 1-50 times, preferably the 5th -25 times the weight of synthetic resin.
  • a resin with too high water absorption capacity causes the ink to dry too slowly and changes the dot, so that the image becomes unclear and illegible.
  • the coating often be separated from the carrier.
  • the above synthetic resin according to the invention is dissolved in a suitable solvent, for example toluene, isopropyl alcohol, dichloroethylene, etc.
  • the ink acceptor layer is formed by applying the dissolved synthetic resin in an amount of 2-15 g / m 2 on the support material.
  • transparent backing material are: glass plates, synthetic resin films (polyethylene, polystyrene, polypropylene, vinyl chloride, vinylidene copolymer, polyvinyl copolymer film, etc.), cellophane, etc.
  • semi-transparent backing material are: glassine paper, tracing paper, etc.
  • a synthetic resin from the vinyl series for example polyvinyl butylene, polyvinyl acetate, polyethylene / vinyl acetate copolymers, etc.
  • polyester resin for example, Vilonal 200 manufactured by Toyobo Co., Ltd.
  • the polyvinyl resin or polyester resin is used in an amount of 5--50% by weight, preferably 20-40% by weight, based on the solvent-soluble synthetic resin with a suitable water absorption capacity, for example modified polyethylene oxide.
  • the coating according to the invention which is formed by applying a solvent-soluble synthetic resin with a suitable water absorption capacity, leads to a uniform layer without fine particles, so that the transparency of the recording sheet is great, and the ink drops are quickly absorbed because of the suitable absorption capacity of the synthetic resin and the ink is fixed after proper spreading.
  • a modified polyethylene oxide (AQUA-PRENE L-710, manufactured by Meisei Chemical Works Ltd., solid content: 15%) was dissolved in isopropyl alcohol (IPA) with stirring to obtain a 10% solution of the synthetic resin.
  • the obtained solution was coated in a coating amount of 7 g / m 2 on a polyester film of 100 ⁇ m in thickness through a sieve bar to obtain a recording sheet.
  • Powdered polyvinyl butyral (PVB; manufactured by Sekisui Chemical Co., Ltd., S-lec BL-3) was dissolved in isopropyl alcohol with slow stirring to obtain a 10% solution.
  • the solution obtained was mixed with the solution of the modified polyethylene oxide from Example 1 in a ratio of 3: 7.
  • the mixed solution obtained was applied to the transparent support in the same manner as in Example 1 to obtain a recording sheet.
  • the following four coating compositions were produced: bridge product of polyacrylic acid (manufactured by SEITETSU Kagaku CO., LTD .: AQUA / KEEP 4S), acrylic acid-acrylamide copolymer (manufactured by Kyoritsu Yuki Kenkyusho, HIMOSAB 200), starch-acrylic acid copolymer ( manufactured by SANYO CHEMICAL INDUSTRIES, LTD., SANWET), starch-acrylonitrile graft copolymer (manufactured by NIPPON STARCH REFINING CO., LTD., WAS) were individually dispersed in IPA to make a 30% dispersion.
  • polyacrylic acid manufactured by SEITETSU Kagaku CO., LTD .: AQUA / KEEP 4S
  • acrylic acid-acrylamide copolymer manufactured by Kyoritsu Yuki Kenkyusho, HIMOSAB 200
  • starch-acrylic acid copolymer manufactured by SANYO CHEMICAL INDUSTR
  • the dispersions were ground into fine particles in a ball mill, thus obtaining dispersions of the various synthetic resin powders with a good water absorption capacity.
  • the individual dispersions were mixed with the PVB solution of Example 2 in the ratio shown in Table 1, and the mixed solutions were applied to the film in the same manner as in Example 1 to obtain a coated film.
  • the powder of the bridge product of polyacrylic acid (AQUA KEEP) of Comparative Experiment 1 was mixed with an aqueous solution of polyvinyl alcohol (PVA 117 manufactured by KURARAY CO., LTD.) As a binder.
  • the mixed solution was applied in the same manner as in Example 1 to obtain a coated film.
  • the powder of the urea formalin resin (Pargopak M, manufactured by CIBA-GEIGY Limited), which is known as a filler in an ink acceptor layer, was mixed with PVB or polyvinylpyrrolidone as a binder in the ratio shown in Table 1.
  • the mixed solution was applied in the same manner as in Example 2 to obtain a coated film.
  • a coated film was made in the same manner as in Example 2, but with the modified polyethylene oxide to PVB solution being 1 to 1.
  • Coated films were made in the same manner as in Example 3, except that polyvinyl acetate (Vinylol 15, made by Showa High Polymer Limited) or polyethylene vinyl acetate copolymers (COARLEX 830, made by The Nippon Synthetic Chemical Industry Co., Ltd.) instead of the PVB- Solution were used in each case.
  • polyvinyl acetate Vinylol 15, made by Showa High Polymer Limited
  • polyethylene vinyl acetate copolymers COARLEX 830, made by The Nippon Synthetic Chemical Industry Co., Ltd.
  • the recording sheets of the invention have superior transparency. Recording sheets with good image clarity and superior multi-colors can therefore be used for overhead projection or as a Blueing copy. Furthermore, the recording sheets according to the invention have superior drying properties, high image density and preferred multi-color recording, because the ink acceptor layer, because of the solvent-soluble synthetic resin with good water absorption capacity, causes high ink absorption and suitably prevents ink spreading.
