Definitions

  • the present invention relates to an improved printing sheet having good ink adhesive properties, sheet running properties, anti-blocking properties, etc., and more particularly relates to an improved printing sheet having good adhesive properties when used with ultraviolet-curable ink (hereinafter, "ultraviolet-curable ink” is referred to as “UV ink”).
  • ultraviolet-curable ink hereinafter, "ultraviolet-curable ink” is referred to as "UV ink”
  • the printing sheet requires, in particular, the property of adhering well to cured UV ink. Additionally, general required properties such as sheet running properties, anti-blocking properties, producing uniform spread of the ink over the surface of the sheet, as well as antistatic properties.
  • the above materials formed in sheets especially films of thermoplastic resin, will not sufficiently adhere with UV ink after printing and curing. Accordingly the printed and cured UV ink has a problem in that the printed and cured UV ink separates from the materials formed in a sheet.
  • This invention has the above-described problems in mind, and an object of this invention is therefore to provide a printing sheet, particularly a thermoplastic film printing sheet, which has superior properties required of printing sheets, and particularly has superior adhesive properties with cured UV ink.
  • a printing sheet comprising a supporting body and a surface layer which covers at least one side of the supporting body and comprises a copolymer consisting of an acrylic monomer having a carboxyl group and an acrylic monomer having an amino group or an amide group.
  • the present invention provides a printing sheet comprising a supporting body and a surface layer which covers at least one side of the supporting body and comprises a copolymer or a homopolymer, which consists of an acrylic monomer having an amino group or an amide group, and a copolymer or a homopolymer which consists of acrylic monomer having a carboxyl group.
  • the expression "acrylic monomer having an amino group or an amide group” denotes, for example, (meth)acrylic amide and all types of (meth)acrylic esters containing amino groups such as a primary amino group(-NH2), a secondary amino group(-NH ), a tertiary amino group( ⁇ N-), etc., particularly, 2-aminoethyl (meth)acrylate, 2-(methylamino) ethyl (meth)acrylate, 2-(dimethylamino) ethyl (meth)acrylate, 2-(diethylamino) ethyl (meth)acrylate, 3-(dimethylamino) propyl (meth)acrylate, 4-(dimethylamino)-n-butyl (meth)acrylate, acrylamide, N-methylolacrylamide, N-ethylolacrylamide, diacetone acrylamide, etc., are given, but are not limited to these.
  • an acrylic monomer having a carboxyl group denotes chemicals such as acrylic acid, methacrylic acid, maleic acid, itaconic acid, etc., but are not limited to these.
  • the "acrylic monomer having an amino group or an amide group” 2-(dimethylamino) ethyl (meth)acrylate, 2-(diethylamino) ethyl (meth)acrylate and N-alkylolacrylamide are preferable, and as the "acrylic monomer having a carboxyl group", acrylic acid and methacrylic acid are preferable.
  • a surface layer denotes a layer which covers at least one side of the supporting body described bellow.
  • This surface layer contains the above copolymer or homopolymer which has the above acrylic monomer, and a composition which is described bellow.
  • the copolymer which has the above acrylic monomer having a carboxyl group, and the above acrylic monomer having an amino group or an amide group denotes copolymers which consist of the above two ingredients, or copolymers which consist of not fewer than one kind of monomer which can polymerize with the above copolymers in addition to the above two ingredients.
  • "a monomer which can polymerize” denotes, for example, a (meth)acrylic monomer, styrene monomer, etc., particularly, n-butyl (meth)acrylate is preferable.
  • the ratio of composition of the above acrylic monomer in the surface layer is the ratio "acrylic monomer having amino group or amide group"/"acrylic monomer having carboxyl group", which is between 8/2 to 2/8 inclusive (mole ratio), and is preferably between 6/4 to 4/6 inclusive.
  • the ratio of the weights of the above acrylic monomers, in the surface layer is over 1%, preferably between 5 to 40%.
  • As the thickness of the surface layer 1 to 10 ⁇ m is preferable.
  • the surface layer is formed on the supporting body by applying a paint which is prepared in which the above compound is dissolved or dispersed in a solvent, water, etc., with a binding resin, if necessary.
  • This paint is applied by the method of roll coating, blade coating, spray coating, air knife coating, rod bar coating, etc., on the supporting body and then dried.
  • a compound of the above material for forming the surface layer is mixed uniformly, and is used to form the surface layer on the supporting body by the method of hotmelt coating or laminating.
  • the binding resin the resin which is generally used for coating and laminating is used. All types of copolymers or homopolymers may be used, for example, polyester resin, acrylic resin, methacrylic resin, vinyl chloride resin, vinyl acetate resin, etc.
  • the surface layer can contain all other additional agents, if necessary, for preventing the blocking of one sheet to another, and for improving the sheet running property, antistatic property, nontranceparency property, etc.
  • a pigment such as polyethylene oxide, silica, clay, talc, diatomaceous earth, calcium carbonate, calcium sulfate, barium sulfate, aluminum silicate, synthetic zeolite, alumina, zinc oxide, titanium oxide, lithopone, satin white, etc., and cationic, anionic and nonionic antistatic agents, etc., may be used.
  • thermoplastic resin sheet a thermoplastic resin sheet, paper, synthetic paper, woven fabric, nonwoven fabric, ceramic sheet, metallic fiber sheet, metalized sheet (film), metallic foil, metallic plate, etc., and a composite sheet, which is formed by combination of the above materials formed into a multilayer structure, are preferred. If a printing machine can be adapted, the form of the supporting body is not limited to, for example, a film, sheet, plate, etc.
  • the printing sheet which has particularly superior adhesive property with cured UV ink, comprises a surface layer which has the copolymer polymerized n-butyl methacrylate and the "acrylic monomer having an amino group or an amide group" which at least one type is selected from the group consisting of 2-(dimethylamino) ethyl methacrylate, 2-(diethylamino) ethyl methacrylate and N-alkylolacrylamide, and the "acrylic monomer having a carboxyl group" which is selected from acrylic acid and methacrylic acid.
  • This surface layer covers the supporting body.
  • a reverse face of the supporting body namely a face not covered by the surface layer
  • a pressure-sensitive adhesive layer which consists of a commonly used pressure-sensitive adhesive agent.
  • a releasing film or sheet consisting of a releasing agent, can cover the pressure-sensitive adhesive layer.
  • This printing sheet can be used for an adhesive label which may be affixed to a number of types of surface. Accordingly, this printing sheet can expand the uses of the printing sheet of this invention.
  • a film made of polyethylene terephthalate and having a thickness of 100 ⁇ m (marketed by the Fuji Film company under the name of PET100G) was used, and on one face of this film, a surface layer was formed by applying a paint which contained the components listed below, and the surface layer was dried. This surface layer had a thickness of 3 ⁇ m.
  • the printing sheets obtained by the above procedure were evaluated in regard to the adhesive properties of the ink, and reproducebility.
  • UV ink (marketed by the Toyo Ink Mfg. Co., Ltd. under the name of FLASH DRY, dark blue) was printed on these sheets, then cured by three UV lamps (5.6kw) at a distance of 14cm between the lamps and the sheets, for 3 seconds.
  • UV lamps (5.6kw) at a distance of 14cm between the lamps and the sheets, for 3 seconds.
  • These printing sheets was evaluated by the I.G.T. printability tester (produced by Kumagaya Riki Co., Ltd.).
