Definitions

  • This invention relates to a photographic light-sensitive material and, more particularly, to a photographic light-sensitive material which comprises a support of a polyester material and which has a light transparency and excellent curl-extinguishing properties after development processing, and these properties are independent of environment with a lapse of time.
  • Photographic light-sensitive materials are generally produced by coating at least one photographic light-sensitive layer on a plastic film support.
  • plastic film fiber type polymers represented by triacetyl cellulose (hereinafter abbreviated as " TAC”) and polyester type polymers represented by polyethylene terephthalate (hereinafter abbreviated as “PET”) are generally used.
  • TAC triacetyl cellulose
  • PET polyester type polymers represented by polyethylene terephthalate
  • PET has conventionally been considered to substitute for TAC due to its excellent productivity, mechanical strength and dimensional stability.
  • PET has a strong tendency to retain the curl from being in the rolled state, and hence its handling properties after development processing are so poor that the scope of its application has been limited in spite of the above-described excellent properties.
  • Photographic light-sensitive materials generally include sheet form types such as X-ray films, plate-making films and cut films and roll films.
  • Typical examples of the roll films are color or black-and-white negative-working films of 35 mm or less in width retained in a cartridge and adapted to be loaded in ordinary cameras for taking photographs.
  • the greatest aspect as a photographic support of TAC films mainly used for roll films is that they are optically non-anisotropic and have a high transparency.
  • they have another excellent aspect. That is, they possess excellent properties as to curl-extinguishing after development processing.
  • TAC films have comparatively high water-absorbing properties for plastic films due to their molecular structure, the molecular chain is fluidized upon absorption of water during development processing and the curling tendency imparted by being kept in a rolled state as roll film for a long time is extinguished as a result of rearrangement of the molecular chain which had been set after being rolled for a long time.
  • TAC provides only a fragile film when formed into film due to its rigid molecular structure and cannot be used in for these advances. Additionally, PET films cannot be used as a roll film where the curling tendency is problematical, in spite of their excellent mechanical properties. Thus, considerable improvement in PET films is greatly desired.
  • US-A-4,217,441 and 4,241,170 disclose that a PET film modified by reacting with a certain specific compound is employed as a support for a photographic material. In this case, however, there arise problems that the film becomes whitening by a processing and a lapse of time, and the transparency of the film is diminished. Therefore, further improvements for the transparency of the film have been desired.
  • US-A-3052 543 discloses a photographic material comprising a specific support film having thereon at least one layer of a copolymer of vinylidene chloride, an acrylic ester and itaconic acid and at least one layer of a water-permeable colloid having protective colloid properties.

  • the water content of polyester film is measured by moisture-conditioning the film under the conditions of 23°C, 30% RH and 3 hours, dipping the film in 23°C distilled water for 15 minutes, and then using a micromoisture meter (for example, model CA-02, made by Mitsubishi Chemical Industries, Ltd.) at a drying temperature of 150°C.

  • the copolymerization proportion of the metal sulfonate-containing aromatic dicarboxylic acid component is preferably about 2 to 15 mol%, particularly preferably about 4 to 10 mol%, based on the aromatic dibasic acid component, e.g., the terephthalic acid component.
  • an aliphatic dicarboxylic acid component containing 4 to 20 carbon atoms in the copolymerized PET film is used in view of transparency, particularly depression of whitening and enhancement of bending resistance of the copolymerized PET film.
  • the aliphatic dicarboxylic acid component containing 4 to 20 carbon atoms there are illustrated succinic acid, adipic acid, sebacic acid, with adipic acid being particularly preferable.

  • the ratio of the refractive index of gelatin to that of PET is 1.5/1.6, which is smaller than 1. Therefore, when light streams through a film edge, the light is liable to be reflected at the interface between the base and emulsion layer, thus polyester type films are liable to cause so-called light piping.
