Description

The invention relates to a photographic support material, which can deliver excellent pictures; it concerns in particular in particular a photographic support material in which a Metal surface with mirror reflection properties or Secondary Diffusion Reflectance Properties with an Adhesive is coated to achieve excellent properties in terms of long-term storage stability, the Heat resistance and weather resistance and at no detachment of a sensitive silver halide layer and no fogging or staining occurs and in which the reproducibility of the hues or Gradation is good, so that a picture with an excellent Image sharpness is obtained.

Examples of common known photographic supports include a transparent plate or a transparent one Film of TAC, PET or polycarbonate; a piece of paper; an art paper; a baryte paper; a movie or a plate that (which) contains a white pigment; or a metal plate, such as As an anodized aluminum plate. Compared to This above-mentioned conventional carriers is apparent a conventional photographic support assembly which is um summarizes a metal surface with specular reflection properties or secondary diffusion reflection properties, a Photograph or a recording medium with a ausge Drew Gradation Playback, with one out drew hue rendering in the case of a color photography and with a good image sharpness. Such Photography or such a recording medium is included For example, described in US-PS 48 51 327, in JP-A-61-210346 (abbreviation "JP-A" as used herein) for an "unaudited published Japanese patent application", JP-A-63-24 247, JP-A-63-24251, JP-A-63-24252,  JP-A-63-24253, JP-A-63-24255, JP-A-63-104234, JP-A-63-118154, JP-A-63-24247.

To create a metal surface with specular reflection Properties or Secondary Diffusion Reflectance Properties can inorganic materials such. Natural Mica, fish scales, pearls and the like., Can be used. In addition, metals such as aluminum, silver, gold, Copper, chromium, nickel or platinum and the like or alloys these metals are used. Among these is aluminum prefers. When metals that are more basic than silver, for Production of a support for photographic or recording sensitive materials with silver halide emulsions are used, there is a tendency that during Be act or development an undesirable veil or unwanted stains occur.

To avoid this problem, it is common practice to use an adhesive material layer of a thermoplastic resin to use. However, this conventional adhesive layer tends to that they develop during treatment or development or during drying after treatment or development solves. Besides, it is difficult to get a thermoplastic resin to make the adhesive layer so thin that it has the desired Thickness of 0.1 to 5 microns has.

Further, there is a problem that mirror reflections or secondary diffusion reflection properties with the passage of longer periods after the treatment development or development is impaired or uneven become.

The aim of the present invention is therefore a photographic To provide carrier material in which a metal surface  with specular reflection properties or secondary diffusion Reflection characteristics with the lapse of long time cleared after treatment or development or unevenly and that is an excellent La has resistance. Another object of the invention is to provide a photographic support material, which is a photographically sensitive material during or after treatment or development does not replace.

The invention is a photographic Trägerma material, which is characterized by an adhesive layer, which is provided on a metal surface, the mirrors reflection properties or secondary diffusion reflections having properties, wherein the adhesive layer according to a Embodiment comprises a copolymer containing vinyl chloride and / or vinylidene chloride, and an epoxy compound. In another embodiment of the invention, the Adhesive layer include polymers which include, for example, poly urethane-urea resins.

As used herein, the term "copolymer containing Vinyl chloride and / or vinylidene chloride "are to be understood as meaning resins which are obtained when copolymerizing vinyl chloride and / or vinylidene chloride, which is the main constituent of the Copolymer, with other components of the copolymer.

A polyethylene terephthalate film having a thickness of 25 μm and containing 25% of silica having an average particle size of 3 μm was placed in a vacuum deposition system as a support. A vacuum evaporation was carried out under a vacuum of 1.33 mPa (10 ^-5 Torr) to produce an aluminum film having a thickness of 600 Å on the support film.

The adhesive composition indicated in Table I below Compositions were diluted with ethyl acetate and in the form of a Layer on the aluminum film applied so that the Beschich amount of adhesive after drying was 5 g / m², then it was dried in an oven at 100 ° C for 2 minutes.  

Table I

A wooden coil consisting of 20 parts LBSP and 80 parts LBKP, was made using a disk refiner ground so that the Canadische Mahlungsgrad 300 cc scam. To the wood coil were added 1.0 part of sodium stearate, 0.5 parts of anionic polyacrylamide, 1.5 parts of aluminum sulfate, 0.5 parts of polyamidepolyaminepichlorohydrin and 0.5 parts Alkylketene dimer added. The parts are calculated as that absolute dry weight, relative to the wooden coil. From the Pulp mixing was performed using a Fourdrinier Pa Punching device weighing a paper 160 g / m² produced. The density of the paper was determined by of a machine calender brought to 1.0 g / cm³.

After a corona discharge treatment on a surface the base paper was applied, became a layer low density polyethylene (MI 7 g / 10 min; density 0.923 g / cm³) on the treated surface of the paper below Application of an extrusion coating in the way up caused the polyethylene film thickness to be 30 μm. also became on application of a Coronaentladungsbehandlung on the opposite surface of the paper made a movie High-density polyethylene (MI 8 g / 10 min, density 0.950 g / cm³) Applied to the treated surface of the paper underneath Application of an extrusion coating in such a way that the Polyethylene film thickness was 30 μm, whereby a polyethylene Laminated film received.

On the back surface of the deposited aluminum films (the opposite side to the vaporized surface) was a two-part polyurethane adhesive with the below composition in the form of a layer so applied that the coating amount after drying 3 g / m², followed by 2 minutes at 100 ° C dried.
