Definitions

  • This invention relates to a cover film employable for protection of a print and a method for production thereof. More specifically, this invention relates to a cover film to be attached on a print which is printed on a sheet of paper employable for printing conducted by employing a type of a printer which uses a water based ink or which is printed on a sheet of paper on which a film for expediting permeation of a water based ink into the paper and for causing clear printing thereon, is attached, for the purpose to project the print from a potential external hazard particularly caused by rain unavoidable, when the print is kept outdoors.
  • the film available in the prior art for expediting permeation of the water based ink into the paper and for causing clear printing thereon is a film of a hydrophilic material such as polyvinyl alcohol, water soluble acrylic resin, water soluble polyester resin, aqueous urethane resin, gelatin, polyethylene oxide or the like.
  • a typical film resistive against the influence of weather and/or climate and which is available in the prior art is a film of polyethylene terephthalate or oriented polypropylene which is coated a film of polyethylene resin, ethylene vinyl acetate copolymer resin, ethylene acrylic ester copolymer resin, ethylene methacrylic ester copolymer resin, ethylene acrylate copolymer resin, ethylene methacrylate copolymer resin, ethylene acrylate acrylic ester copolymer resin, ethylene methacrylate acrylic ester copolymer resin, ethylene acrylate methacrylic ester copolymer resin, ethylene acrylate methacrylic ester copolymer resin or ethylene methacrylate methacrylic ester copolymer resin.
  • the cover film available in the prior art is, however, involved with the following drawbacks. Firstly, the cover film is inclined to be readily removed from the print which is produced by printing conducted on a sheet of paper which is coated with the foregoing film for expediting permeation of a water based ink into the paper and for causing clear printing thereon and which actually is made of a hydrophilic material, in a rather long period in which the print is kept outdoors. Secondly, the process to cover the print with the cover film must be conducted at a relatively high temperature for example 100° C.
  • the first object of this invention is to provide a cover film employable for protection of a print which is printed on a sheet of paper employable for printing conducted by employing a type of a printer which uses a water based ink or which is printed on a sheet of paper on which a film for expediting permeation of a water based ink into the paper and for causing clear printing thereon is attached, for the purpose to protect the print from a potential external hazard particularly caused by rain unavoidable, when the print is kept outdoors, wherein the effects of the protection is durable for a long time and the cover film can be attached on a print at a relatively low temperature.
  • the second object of this invention is to provide a method for producing the foregoing cover film.
