Definitions

  • the present invention relates to a recording material for use in recording by a visual recording method by means of printing, writing, or the like.
  • a reception layer corresponding to a record method in each record method is provided on a surface such as the plastic sheet, and then each record is generally performed.
  • the record reception layer corresponding to the record method in each record method must be provided, and intricacy is apt to occur inevitably.
  • EP-A-0701179 discloses a printing plate comprising an image receiving layer provided on a surface of plastic film, wherein the image receiving layer comprises two kinds of extender pigments having different average particle size ranges to impart unevenness to surface of the image receiving layer.
  • JP-A-11227316 discloses a recording medium having an ink receiving layer containing two kinds of amorphous silica having different average particle sizes.
  • the present invention provides a recording material in which a resin layer containing both of a large particle size sponge silica having a particle size 8 to 18 ⁇ m and a small particle size sponge silica having a particle size 1 to 7 ⁇ m is provided as a record reception layer on at least one face of a base material.
  • the pore volume of said silica is 0.7 to 7 ml/g.
  • the sponge silica is manufactured by a gelling method.
  • the base material used for the present invention is not in particular restricted if the base material is a material on which a record reception layer can be provided, but in a material in which the base material per se does not also contain a plurality of species of record reception property, effects of the present invention are especially great.
  • the base materials a film, a sheet, a plate, a spin-coated CD disc or the like composed of polyethylene, polypropylene, polyester, polycarbonate, polymetaacrylate, a metal or the like are illustrated.
  • a paper, a synthetic paper or the like can also be illustrated.
  • a pore volume of the silica used for the present invention is 0.8 to 4ml/g. If the pore volume of silica is too small, there is a tendency that the record reception property of the reception layer is lowered. Furthermore, if the pore volume of silica is too large, the viscosity of the resin liquid substance constituting the reception layer is conspicuously high, and there is a tendency that a coat operation is conspicuously difficult in a manufacture of the recording material (according to another aspect of the present invention).
  • a resin solution As the resin liquid substance, a resin solution, a resin emulsion, a melted hot melt resin, a two-part curing type uncured resin, an ultraviolet rays curing type uncured resin , or the like can be illustrated.
  • operations of curing after these resin agents are coated or printed on the base material evaporation, cooling, or heating of a solvent or a dispersing medium, or ultraviolet rays irradiation or the like is adopted in response to each substance.
  • use of a non-water-soluble resin is preferable in order to attain excellent water-resistance.
  • the large particle size sponge silica and the small particle size sponge silica are both used in the record reception layer in the present invention.
  • the large particle size silica has a particle size of 8 to 18 ⁇ m. And if only the large particle size silica is used, there occurs drawbacks that sedimentation of silica occurs in the resin agent and it is easy to cause quality variations in the reception layer, and further rub-resistance of the reception layer is lowered, etc.
  • a weight ration of the small particle size silica to the large particle size silica is about 0.1 to 5.
  • the record reception layer in the present invention contains silica and a resin.
  • silica amount and the resin amount if the former is too much, a reduction in the rub-resistance of the record reception layer is caused, and if the latter is too much, a reduction in reception performance is caused. Accordingly, it is preferable that a resin of 15 to 150 pts.wt. per 100 pts.wt. of silica is used.
  • the pore volume of silica is about 0.8 to 4ml/g as described above. If the pore volume is too small, a reduction in the reception performance is caused, and there is a tendency that the rub-resistance is also lowered. If the pore volume rate is too large, it becomes easy to cause a reduction in strength such as the rub-resistance of the record reception layer. Furthermore, it is not necessarily necessary that the pore volumes of the large particle size silica and small particle size silica are the same.
  • additives such as silica of a particle size 7 to 8 ⁇ m, a surfactant, a leveling agent, a dye fixing agent, various pigments, various fillers or the like can from time to time be used as an object demands.
  • the sponge silica means silica of a sponge-like structure having many pores in silica particles.
  • a sedimenting method and a gelling method exist, and it is possible to obtain silica which has a sufficient pore volume in case of using the gelling method.
  • the sponge silica which is a structural element according to the present invention is manufactured by the gelling method.
  • the present invention provides the recording material in which the reception layer is provided on one face of the plastic sheet and the adhesives layer is provided on the other one face.
  • This adhesives layer is freely peeled off and re-adhered, preferably.
  • This adhesives layer which is freely peeled off is formed by applying or drying an adhesives solution or an emulsion containing an adhesive minute sphere of a particle size 2 to 100 ⁇ m on the base material, or formed by applying a radioactive rays curing ink on the base material, and next irradiating radioactive rays.
  • any one of screen printing, offset printing, photogravure printing, flexographic printing, letter press printing, roll coating, spray coating and the like may be used, and the screen printing in which a film thickness of the adhesive layer can be increased is the most suitable.
  • a pattern of printing or coating when the adhesive layer is formed may be set solid all over, set linear, set dotty, or set designed, and the printing or coating may be performed in an area of 10% or more of a sheet-like base material, preferably 20% or more thereof.
  • the film thickness of the adhesive layer is preferably 4 ⁇ m or more, and it is particularly desirable that the film thickness is 10 ⁇ m or more from a viewpoint of re-exfoliation and adhesive stability.
  • a coat agent composed of 50 pts.wt. of silica of a pore volume 1.9ml/g and a particle size 11 ⁇ m, 50 pts.wt. of sponge silica of a pore volume 1.7ml/g and a particle size 5 ⁇ m, and 500 pts.wt. of acrylate emulsion of resin concentration 10% is coated on a polyester sheet, water is heated and evaporated, to form a recording material A in which a reception layer is provided on one face of a polyester sheet. Furthermore, recording materials B, C, D, E, F, G are made according to the similar step. A composition of the reception layer of these recording material is designated on Table 1.

  • mark ⁇ in Table 2 indicates that both definition and rub-resistance of records are excellent, and mark ⁇ indicates that one or both of them is inferior.
  • the decision was made by visual observation.
  • the rub-resistance the decision was made according to whether or not characters and drawings were blurred by rubbing the characters and drawings which were printed, written and sealed by a finger.
  • the embodiments 1 to 5 were excellent in the definition and rub-resistance of records in any one of the various present record methods (the oil ink printing, the toner printing (a copy by a copy machine), the thermal transfer printing, the ink-jet printing, the entering by a water pen, the entering by an oil pen, the entering by a pencil, the stamp sealing, and the vermilion inkpad sealing).
  • the adhesives layer or the adhesives layer which can be freely peeled off is provided on a back face of the sheet of these embodiments 1 to 5, so that the sheet which is excellent in the definition and the rub-resistance of the records and can be held to a glass face, a desk face, or the like by the adhesives layer can be attained.
  • the drawings or characters are clearly recorded without being ink-stained, and furthermore it is possible to provide the recording material in which the recorded drawings or characters display excellent strength, for example excellent rub-resistance, or the like. Furthermore, it is possible to also provide the recording material which is excellent in the vivid record and rub-resistance, and can be adhered or re-exfoliated.
