（４）(Industrial Application Field) The present invention relates to a cover film for a sublimation heat transfer hard copy.The sublimation heat transfer hard copy referred to herein means:
(This refers to a product that is sublimated and transferred to an image-receiving sheet.) (Prior Art) There has been active research into methods for reproducing images in the form of hard copies such as photographs from electrical image signals obtained from video cameras, still video cameras, televisions, video disks, photo-electrotransmission devices, etc. Currently, sublimation thermal transfer (image) recording method is attracting attention as one of the promising methods.Sublimation thermal transfer recording is a thermal image recording method in which, for example, 4 to 16 dots of electric heating elements are lined up per 1 m. An electrical signal containing image information is sent to the head, and at the same time, an overlapping sheet of "an ink sheet in which a sublimable dye layer is coated on the surface of a support sheet" and an "image receiving sheet" is brought into contact with the head. The dye from the ink sheet is transferred in dots to the image receiving sheet by moving the ink sheet, thereby producing a hard copy.The dye sublimation thermal transfer hard copy obtained in this way is
Office supplies such as paper, notebooks, books, forms, scrapbooks, card cases, and letter cases were organized and stored according to their purpose. [Problem to be solved by the invention] However, if the sublimation transfer surface is in contact with the office supplies for a long period of time due to storage of office supplies, there is a drawback that the contact area will be colored by the re-sublimated sublimation dye. was there. (Hereinafter, this phenomenon will be referred to as "contamination.") Furthermore, the obtained images tend to discolor or fade due to heat, light, various gases, etc., and they also have the disadvantage of poor storage stability. An object of the present invention is to provide a cover film that has excellent stain resistance, discoloration resistance, and discoloration resistance and is used when storing sublimation thermal transfer hard copies. c! Means for solving ia] For the above purpose, in the present invention, in the film (1) that covers the sublimation transfer surface of the sublimation type thermal transfer hard copy (2), the film (1) is non-dyed on the - side. Substance support (12)
, a non-dyeing material such as a non-dying layer (14), and a gas-impermeable material such as a gas-impermeable layer (11) and a gas-impermeable support (13) on the other side; At least one of the non-dyeable material and the gas non-permeable material contains an ultraviolet absorber, and further, when the film ( ) is used, the − surface is always in contact with the sublimation transfer surface. is used as a means of solving problems. [Function] The cover film of the present invention has a non-dyeing layer for sublimation dyes on the side that contacts the sublimation transfer surface of the sublimation heat transfer hard copy, so it can cover the sublimation heat transfer hard copy for a long period of time. The cover film will not be colored even if it is coated with a film. Therefore, when using the cover film that has been used once again, there will be no trace of the image from the previous dye sublimation type heat transfer hard copy, so it can be used again and again. . Furthermore, since a gas-impermeable layer is provided on the other side of the cover film, the sublimable dye re-sublimated from the sublimation type thermal transfer hard copy does not pass through the cover film, so it does not contaminate anything it comes in contact with, and also causes image deterioration. It becomes a factor of
Since gases such as water vapor, oxygen, and ozone do not enter from the outside, there is little discoloration or fading of images. The non-dyed layer of the present invention is composed of a resin that has no affinity with sublimable dyes. For example, the solubility parameter (hereinafter S
Examples include polymers having a P value (abbreviated as P value) of 9.0 or less, preferably 8.5 or less. The SP value is often used to express the chemical affinity, compatibility, etc. of two or more substances, and the lower the value, the lower the affinity. In the present invention, a material having an SP value of 8.5 or less, such as silicone resin, Teflon resin, polyethylene, or polypropylene, is used. Furthermore, hydrophilic resins such as cellophane and polyvinyl alcohol can also be used. For the gas impermeable layer of the present invention, a resin having low water vapor and oxygen permeability is generally used. For example, the permeability of oxygen and water vapor is 50×10”cd-CI/CI!・sec・
cmHg or less, preferably 30 x 1012 cd −
cm/c4-sec-crsHg or less is preferable. Examples of such resins include polyvinylidene chloride, polyester, polyvinyl chloride, polyvinyl buttate, and the like. Since the cover film of the present invention contains an ultraviolet absorber in one of the layers, it can also prevent discoloration and fading due to light. Contains ultraviolet absorber of 300-400nm
It is preferable to use a compound that absorbs ultraviolet rays, and for example, benzophenone-based, benzotriazole-based, or salicylate-based compounds can be used. The cover film of the present invention can be produced by coating a non-dyed film with a solution containing a gas-impermeable component, or by coating a gas-impermeable film with a solution containing a non-staining component. The UV absorber may be mixed in advance at the time of film production, or the UV absorber may be mixed in advance during film production.
It may be mixed in when coating any of the layers.The thickness of the non-dyeing layer and the gas impermeable layer is preferably 2 to 100 μm, preferably 5 to 50 am, and the thickness of the cover film is 5 to 200 μm. Preferably it is 20 to 100 μm. In the present invention, a writable layer is provided on the gas-impermeable material side of the cover film to make it easier to organize and store the sublimation type thermal transfer hard copies. The writable layer was formed by applying a coating liquid containing an inorganic filler such as titanium oxide or clay or an organic filler such as a silicone resin or an epoxy resin and a polymer onto the gas-impermeable layer or polyvinyl chloride film. The writable layer thus provided can be used to write the contents, date, etc. on the writable layer using a pencil, ballpoint pen, or the like. As a method for coating the above-mentioned liquid containing each component on each support, means such as a reverse coater, a roll coater, a Clavia coater, etc. can be used. [Example] Figure 1 shows a first example of the present invention, in which a gas impermeable layer (

) was adhered to produce a cover film. In addition, depending on the purpose of use, it may be possible to just use them one on top of the other, and there is no need to adhere them.Also, it has been determined that the test results of the third example can be predicted by confirming the test results of the first and second examples. However, no tests were conducted. Furthermore, other films were prepared for comparison with the cover film (1) of the present invention. (First Comparative Example) A nylon film having good gas impermeability (Harden, manufactured by Toyobo ■) having a thickness of 15 μm was used as a cover film, and was subjected to the same test as in the first example. (Second Comparative Example) A 20 μm thick polybrene film (manufactured by Torefan, Toshiki Co., Ltd.) with good non-staining property was used as a cover film and subjected to the same test as in the first example. (Third Comparative Example) For comparison, with the cover film removed,
It was subjected to the same test as in the first example. The test results of each Example and each Comparative Example prepared as above are shown in Table 1. (Test results) Table 1 0 The degree of staining coloration is expressed as O: none, Δ: a little, ×: quite a bit. 0 The density value of storage stability indicates the density value after the test corresponding to the density value of 1.6 of the produced sublimation type thermal transfer hard copy. From Table 1, it can be seen that when the cover film is composed of a non-dyeing layer and a gas impermeable layer as in the first and second embodiments of the present invention, the cover film is not colored and can be used many times. , there is no contamination of other contact objects, and the image has good storage stability. On the other hand, although the cover film of the first comparative example has good stain resistance, the cover film itself becomes colored and cannot be used for other image samples. Furthermore, although the cover film of the second comparative example has little coloring on itself, it is poor in gas impermeability, so the sublimable dye passes through the film, causing the paper it comes into contact with to be colored. FIG. 4 is a diagram showing an example of use in which a cover film is processed into a bag shape. In FIG. 4, the inside of the cover film bag (40) is a non-dyeable layer or support of a non-dyeable material. The outer side was made of a gas-impermeable layer or a support made of a gas-impermeable material, and a writable layer (41) was provided on the surface thereof. FIG. 5 shows an example of use in which a cover film is fixed to a mount and a sublimation thermal transfer hard copy is sandwiched between the mount and the cover film. The backing side of the cover film (51) is a non-dye layer or support for a non-dye material. The other side is a gas impermeable layer,
Alternatively, it is made of a support made of a gas-impermeable material, and although not shown, it is possible to write on the surface of the support. (41) is provided. [Effects of the Invention] As described above, according to the present invention, a cover film having non-staining properties, gas impermeability, and ultraviolet absorbing properties can be obtained, which is very useful for managing and storing dye-sublimated thermal transfer hard copies, etc. effective. In addition, since a writable layer is provided as shown in the usage example, there is an advantage that management and writing of contents of stored items is facilitated. Furthermore, it can be made into a bag shape or fixed on a mount, so
