Definitions

  • ABSTRACT A support for use in photographic materials which is not subject to excessive curling and which has a back side which can be written on is produced by a process which comprises contacting one side of a polystyrene film containing dispersed white pigment with a first liquid which strongly swells or dissolves the polystyrene, contacting the other side of the polystyrene film with a mixed solution of a second liquid which swells or dissolves the polystyrene greater than the first liquid and a third liquid which has almost no ability to swell or dissolve polystyrene and then drying the polystyrene film to remove the liquids.
  • the surface treated with the first liquid is generally to be coated with a photographic emulsion, the surface treated with the mixed solution can be written upon.
  • the present invention relates to a process for producing a support for use in a photographic material and, more particularly, to a novel support for use in a photographic printing material which is excellent in water resistance and curl balance.
  • the inventors previously suggested a process for producing a water-proof support for use in a photographic material which comprises contacting the surface of a polystyrene resin film containing dispersed therein a white pigment with an organic solvent which exhibits a strong swelling or dissolving action on the resin and drying the thus treated film to impart excellent gloss to the support.
  • the surface of the support is then coated with a photographic emulsion layer to prepare a photographic material having excellent gloss and high photographic resolving power.
  • both sides of the support In order to avoid such a curling phenomenon, one can treat both sides of the support under the same conditions. However, though such treatment renders the contraction of both sides of the support well balanced and no curling appears, both sides of the support are rendered glossy by the treatment resulting in the loss of the writing property, printing property, pasting property and like properties required of the back side. Furthermore, in a support for a photographic material it is more desirable that the support itself be a little curled or convex with respect to the surface thereof rather than the support be completely planar.
  • the present invention is a process for producing a support for a photographic material which comprises the step of contacting one side of a polystyrene resin l'ilm containing dispersed therein a white pigment with a first liquid having a strong power to swell or dissolve the polystyrene resin; contacting the other side of the polystyrene resin with a mixed solution consisting of a second liquid having a stronger power to swell or dissolve the polystyrene resin than the first liquid and a third liquid having no or an extremely low power to swell or dissolve the polystyrene resin; and drying the film to remove the liquids used in the foregoing steps.
  • the polystyrene resin used in the present invention includes copolymers of styrene and a copolymerizable monomer(s) as well homopolymers of styrene.
  • styrene there are used styrene and substituted styrenes such as alpha-methylstyrene.
  • comonomers copolymerizable with the styrene are acrylonitrile, butadiene, methyl methacrylate, ethylene, propylene, vinyl acetate, and the like.
  • Styrene homopolymer or copolymers can be obtained by polymerizing styrene or copolymerizing styrene with two or more of the above-described compounds.
  • polymers containing styrene as a component are a styrene homopolymer, impact resistant polystyrene, an acrylonitrile-styrene copolymer, an acrylonitrile-styrene-butadiene copolymer, a methylme thacrylic ester-styrene copolymer, an a-methylstyrene homopolymer and like a-methylstyrene copolymers.
  • styrene resins generally have an average molecular weight in the range of from about 80,000 to about 500,000.
  • the polystyrene resins used in the present invention include a polystyrene resin alone as defined above and a mixture comprising such a polystyrene resin and other synthetic resins.
  • the above mixture preferably contains the polystyrene resin predominantly, for example, mixtures comprising about 3 to about part, preferably, about 5 to about 50 parts by weight of synthetic resins other than polystyrene resin per parts by weight of the polystyrene resin are desirable.
  • the synthetic resins which can be used as a mixture with the polystyrene resin include ethylene-vinyl acetate copolymers, ethylene-acrylic ester copolymers, ethylenemethacrylic acid ionomers, ethylene-acrylic acid ionomers, butadiene-acrylonitrile copolymers, ethylenepropylene copolymers, natural rubbers, synthetic isoprene rubbers, butadiene rubbers, styrene-butadiene rubbers, high-styrene content rubbers, polybutadienes, chloroprene rubbers, polybutenes, butyl rubbers and nitrile rubbers. These synthetic resins can be used alone or as combinations of two or more thereof.
  • the resin blends containing polystyrene resin as a main component can be used as a support because the support of materials as described above is suitable for a photographic support due to its toughness. which is almost the same as that of a base paper. considering a conventional photographic paper having a thickness on the order of from 100 to 300p.
  • the other various synthetic resins as enumerated above can be added to the polystyrene resin in order to improve the moldability and the tear strength and to adjust the toughness or the feel.
  • the other synthetic resins incorporated into the polystyrene resin are generally thermoplastic polymers having a relatively high elasticity.
  • the fine powder of white pigment(s) incorporated into the above resin(s) are used for obtaining whiteness and a masking effect desirable for the support of photographic material.
  • Examples of the white pigment used in the polystyrene resin include titanium dioxide, zinc white, barium sulfate, calcium sulfate, calcium carbonate, barium carbonate, lithopone, alumina white, etc., which may be used alone or as combination of two or more thereof.
  • a preferred white pigment is titanium dioxide, in particular, titanium oxide having a rutile-type structure. Any white pigment can be used in the present invention so long as it provides sufficient coloration to render the polystyrene light and is not dissolved and does not harmfully react with any of the treating liquids.
  • the phenomona of pigment loading is essentially a physical one, and no undue criticality is attached to the selection of any particular white pigment, for instance, the pigments need not be inorganic, though they commonly are, if they meet the above criteria. All are used as fine powders having a mean grain size of 0.05 10 microns, preferably less than 1.5 microns and most preferably less than 1 micron. White pigments having an average grain size of less than 1 micron are particularly preferred since they generally provide a sheet having smooth surfaces when incorporated into the polystyrene resin used in the present invention.
  • the white pigments are dispersed in the aforesaid polystyrene resin in a proportion of 2 40 /1, preferably 5 to 30% by weight based on the polystyrene resin.
  • the dispersion may be effected by any known method. However, it appears to be the most general method in this art to mix the white pigment with a powdery polystyrene resin and mold it into pellets while kneading with an extruder. Usually. a sheet is formed by extrusion using the resulting pellets as the starting material. However, a film may also be formed directly (i.e., without molding pellets) by feeding the powdery composition into a film-forming machine equipped with a kneading mechanism. Other film-forming process using as the starting material the powdery composition, are known, and any of them may be selected and utilized.
  • the thickness of the polystyrene resin film intended in the invention is in the range of from about 50 to about 350 microns. preferably from about 100 to about 300 microns, but is not limited only to this range.
  • one side of the abovedcscribcd polystyrene resin film is brought into contact with a first liquid strongly swelling or dissolving the polystyrene resin.
  • swelling power as is used herein to define this phenomenon is evaluated as follows.
  • strong swelling power means a swelling power corresponding to a slope larger than that of methyl isobutyl ketone.
  • major component of the first liquid having such property there are, in order of decreasing strength of swelling power, methylene dichloride, trichloroethylene, chloroform, ethylene dichloride, carbon tetrachloride, tetrachloroethane, benzene, methyl acetate, toluene, ethyl acetate, xylene, methyl ethyl ketone, solvent naphtha and the like.
  • the first liquid is a single-component liquid or a liquid composition containing at least the abovedescribed organic solvent having the power to swell or dissolve the polystyrene resin used.
  • the essential criterion which must be met in such a liquid composition is that the composition have a swelling power less than the second liquid and greater than the third liquid.
  • a single first liquid as de scribed above will be the major component of such a system, i.e., more than 50 volume 70, preferably more than volume 70.
  • Various coating techniques can be used to contact the resin with the first liquid, such as impregnationcoating, beadcoating, spray-coating, etc., all of which are conducted in the same manner as has heretofore been used in any.
  • the contacting is effected to the extent that there is observed a swelling or dissolution of the surface of the polystyrene resin film.
  • the support when dried, will have a surface of a beautiful gloss.
  • the first, second and third liquids can be freely selected from a wide range of materials so long as they meet the relative swelling power criteria defined, i.e. in order of decreasing swelling power for polystyrene second liquid, first liquid, third liquid, with the third liquid most preferably being a non-solvent or substantial nonsolvent for polystyrene.
  • substantial non-solvent is meant that if polystyrene is contacted with the third liquid per se no swelling is observable during contact times as are used in the present invention.
  • any second liquid which exhibits a stronger swelling power than the first liquid can be used, with better results being obtained the greater the difference in swelling power between the first liquid and second liquid.
  • the opposite side of the polystyrene resin film to the treated side is brought into contact with a mixed solution consisting of the earlier described second liquid and third liquid.
  • a mixed solution consisting of the earlier described second liquid and third liquid.
  • the treated surface becomes a coarse surface having a fine roughness.
  • the phenomenon of forming a coarse surface does not vary so much in the end over a wide compositional range for the mixed solution (i.e., roughly speaking, over the range of the ration of the third liquid/(the second liquid the third liquid) of several to several ten 70).
  • the second liquid is generally admixed in an amount more than the amount of third liquid, and the effects of the mixture are obtained over a wide range, most preferably 2-30 volume of the second liquid, though this upper value is not limitative.
  • the second liquid is a liquid having a stronger power to swell 0r dissolve polystyrene resin than the first liquid.
  • the third liquid is a liquid having no or an extremely small power to swell or dissolve the polystyrene resin. Therefore, these second and third liquids are selected depending upon the particular polystyrene resing and the first liquid used.

  • the mixing ratio of the strong solvent to the non-solvent in the mixed solution to be brought into contact with the side not to be coated with a photographic emulsion should be properly adjusted depending upon the kind of the solvent to be contacted with the side to be coated with a photographic emulsion, the thickness of a gelatin-containing photographic emulsion layer to be coated thereon and the curling degree desired in the complete product.
  • Either of the steps of contacting each side of the polystyrene resin film with the liquid may be firstly conducted, or both treatments may be conducted at the same time.
  • each treatment may be conducted in one step or in two or more steps.
  • the resin film may be contacted one by one with several kinds of liquids belonging to the category of the same type that of the respective liquids.

  • the exact time is best empirically selected and this is done, usually, merely by varying temperature of contact for a few process runs until a desired product is obtained.
  • the polystyrene resin film is subjected to a drying step. It is preferred toeffect drying so that the liquids used in the preceding two steps areremoved as completely as possible. In addition, there is no problem when the drying is conducted to the extent that the polystyrene support itself is not softened, e.g., usually at a temperature less than C.
  • a curling value of 0 means that the film is planar with no curling. Curling in a convex form with respect to the photographic emulsion-coated side or the side to be coated with the photographic emulsion is evaluated as a curling, whereas curling in a concave form is evaluated as a curling.
