- ABSTRACT A method for providing a subbing layer on a photographic film where a biaxially stretched and heat-set polyethylene terephthalate film is to be provided with a hydrophilic surface comprising applying an aqueous solution containing hydrogen peroxide to the treated surface, applying ultra violet radiation while the coated surface is wet and then applying a hydrophilic resin solution or gelatin dispersion containing a solvent or swelling agent for the polyethylene terephthalate to thereby form the subbing layer.
- the present invention relates to a method for providing a subbing layer on polyethylene terephthalate, and particularly to a method for providing a subbing layer on a polyethylene terephthalate film used for photography which is subjected to biaxial stretching and heat setting.
- PET film Polyethylene terephthalate film which is subjected to biaxial stretching and heat setting
- PET film Polyethylene terephthalate film which is subjected to biaxial stretching and heat setting
- it is called PET film has been widely used as the support of sensitive elements, printing elements and photographic films, because it has an excellent mechanical strength and a good dimensional stability.
- it is difficult to bind firmly a sensitive emulsion layer which contains hydrophilic gelatin to the PET film because the surface of the PET film is hydrophobic though it has excellent properties as the photographic film support.
- a method which comprises applying a hydrophobic resin which adheres well to the PET film and has a good solubility and applying a hydrophilic resin thereto.
- such method for providing a subbing layer is not suitable in economic viewpoint and in preparation steps, since a polymer having a high price must be used and two layers must be provided.
- the PET photographic film support in which the abovementioned faults are improved can be prepared by the following method. Namely, the PET film support is subjected to treatment for affording a hydrophilic property to the surface thereof, such as corona discharging, flame treatment, ultraviolet ray application, ozone oxidation, high frequency treatment, ultrasonic treatment and acid treatment by any common manner. Then an aqueous hydrogen peroxide solution or one containing a water soluble solvent is applied to the treated surface. Then, the treated surface is subjected to ultraviolet ray application while it is in a wet state.
- treatment for affording a hydrophilic property to the surface thereof such as corona discharging, flame treatment, ultraviolet ray application, ozone oxidation, high frequency treatment, ultrasonic treatment and acid treatment by any common manner.
- an aqueous hydrogen peroxide solution or one containing a water soluble solvent is applied to the treated surface.
- the treated surface is subjected to ultraviolet ray application while it is in a wet state
- a solution of a hydrophilic resin or a dispersion of gelatin in the solvent (which are prepared using a mixed organic solvent containing a solvent or swelling agent of PET) is applied, by which a subbing layer is produced on the PET film support.
- a solution of a hydrophilic resin or a dispersion of gelatin in the solvent (which are prepared using a mixed organic solvent containing a solvent or swelling agent of PET) is applied, by which a subbing layer is produced on the PET film support.
- the concentration of hydrogen peroxide is not prescribed, 0.001-30 percent is especially effective. It is possible to improve uniformity of the application by adding a water-miscible solvent such as methanol and dioxane, etc. or a surface active agent etc.
- the aqueous hydrogen peroxide solution can be applied by the well-known method such a dipping method, roll coating method and air-knife method.
- the treatment for applying the ultraviolet rays in the next step is affected by the degree of wetness of the PET base. In general, the treated PET base having an improved surface property can be obtained when more than 0.1 percent of water on the average of the whole film remains.
- Japanese Patent Publication Nos. 2603/68 corresponds to U.S. Pat. No.
- the desired adhesive effect is obtained by enhancing the degree of the treatment of ultraviolet ray application in the PET base which is not wet at all.
- the light source used for the ultraviolet ray application is not subject to restriction, a mercury lamp made of quartz is conveniently used.
- the degree of the ultraviolet ray application differs with the conditions of previous treatment, kind and intensity of the light source, distance between the light source and the object to be applied and temperature of the object to be applied, but, in any case, it can be changed so as not to cause deterioration of the quality of the PET base by the ultraviolet ray application.
- a solvent or a swelling agent for PET is included in the hydrophilic resin solution or gelatin dispersion used in the present invention, but the amount of the solvent or the swelling agent can be changed suitably depending on the conditions of radiation, kind of the solvent or swelling agent of PET and kind of another coexisting organic solvents. Further, two or more of the solvent or swelling agents for PET may be used at the same time.
- Additives used for reinforcement of the subbing layer, improvement of the adhesive property of the support or the photosensitive emulsion layer, prevention of electrostatic charging or coloring of the support, such a hardening agent, antistatic agent, dyes, and hydrophilic or hydrophobic high molecular compoundsv may be added to the solution for providing the subbing layer in addition to the hydrophilic resin, gelatin, gelatin swelling agent, dispersing agent and organic solvent.
- a hardening agent for example, ethyleneimine derivatives, epoxy derivatives and hydrophobic high molecular compounds, such as a partially saponified vinyl chloride-vinyl acetate copolymer, and especially cellulose nitrate, may be added to the solution for providing the subbing layer, by which the desired adhesive property is obtained by ultraviolet ray application in a period shorter than in the case of not adding such material.
- the method of the present invention it is possible to obtain a photographic film having a good surface property and a good adhesive property by decreasing the-amount of ultraviolet ray radiation. Further, the photographic property of the photosensitive emulsion is not affected by such treatment.
- the adhesive property of the photosensitive emulsion layer to the film support is determined and evaluated by the following generally used method.
- Adhesion test in dry state surfaces of the emulsion layers on an untreated film and-a treated dry film are scratched by a razor to prepare mesh-like linear scratches (interval between lines: about 4 mm). Then an adhesive tape is stuck on the emulsion layer and peeled off rapidly, such as polyester adhesive tape produced by Nitto Electric Industrial Co., Ltd.
- grade A means the case that an unpeeled part is about 95 percent
- grade B means the case of being above 70 percent
- grade C means the case of being up to 70 percent.
- Adhesion test in wet state in each step of develop- I ment, fixing and washing, the films are scratched on the BRIEF EXPLANATION OF DRAWING
- the FlGURE is a sectional view of an apparatus for providing a subbing layer of the photographic 'film.
- EXAMPLE 1 In the FIGURE. a PET film support 1 having a 30 cm width and 10041. of thickness was sent out from A (web feeding portion) and was subjected to corona discharging between a corona discharge treating roll 2-1 and a rod electrode 2-2 by a common method using a LEPEL type surface treating apparatus. The PET film support was let pass at a 3.0 m/min speed, 10 kc frequency, 0.8 mm interval of the rod electrode film and 50 Wet electric power. Then the treated base was sent to the part 3 for applying an aqueous hydrogen peroxide solution, at which a 0.015 percent aqueous hydrogen peroxide solution was applied by passing through a coating pan 4.
- the base was then sent to an ultraviolet ray application room 5 where the film was radiated by two 1 kw cylindric quartz mercury lamps 6. (length of arcuate portion: approximately cm) which were disposed at 20 cm from the film surface.
- the treated film was dried in a drying room 7.-Then the film was sentto a coating room 8where a solution for providing a subbing layer having the following composition was applied by passing through a coating pan 9.
- the film was then dried in a drying room 10 and rolled at B (winding portion).
- composition of the solution for providing the subbing layer is a composition of the solution for providing the subbing layer
- Adhesive strength in the dry state and the wet state of a photographic sensitive film which was prepared by applying a gelatin-silver halide emulsion to the PET film support having the subbing layer and drying was superior. Photographic properties of this photographic sensitive film were excellent.
- EXAMPLE 2 A PET film support having a 75p. thickness and a 30 cm width was treated by passing at a speed of 4.0 m/min., kc frequency a, 0.8 mm interval between rod electrode-film and 100W of electric power using the same apparatus as in Example 1. Then an aqueous hydrogen peroxide solution prepared by dissolving parts by volume of methanol in 80 parts by volume of a 0.01 percent aqueous hydrogen peroxide solution was applied thereto. After applying ultraviolet rays and drying by the same manner in Example 1, a solution for providing the subbing layer having the following composition was applied. After drying the film was rolled.
- composition of solution for providing subbing layer is a composition of solution for providing subbing layer
- Adhesive strength in the dry state and the wet state of a photographic sensitive film produced by applying gelatin silver halide emulsion to the film support having the subbing layer and drying was superior. Photographic properties of the resulting photographic sensitive film were excellent.
- composition of solution for providing subbing layer is a composition of solution for providing subbing layer
- Adhesive strength in the dry state and the wet state of a photographic sensitive film which was prepared by applying a gelatin-silver halide emulsion to the PET film support having such subbing layer and drying was superior. Photographic properties of the resulting photographic sensitive film were also excellent.
