Definitions

  • the invention relates to a photographic paper support with a waterproof coating made of a polyolefin.
  • Waterproof photographic papers consist of a base paper with synthetic resin coatings applied on both sides, which are either made of polyolefins, e.g. B. made of polyethylene, and are applied to the paper by means of extrusion coating or from organic lacquer mixture which are applied to the paper by means of dipping or spraying and dried and solidified by means of heat or high-energy radiation.
  • synthetic resin coatings applied on both sides, which are either made of polyolefins, e.g. B. made of polyethylene, and are applied to the paper by means of extrusion coating or from organic lacquer mixture which are applied to the paper by means of dipping or spraying and dried and solidified by means of heat or high-energy radiation.
  • One or more photosensitive coatings based on silver halide are then applied to one of the synthetic resin layers.
  • the light-sensitive layers can be black and white as well as color photographic layers.
  • the synthetic resin film (front coating) arranged under the light-sensitive layers usually contains light-reflecting white pigment and, if appropriate, color pigments, optical brighteners and / or other additives, such as antistatic agents, dispersants for the white pigment, antioxidants, release agents and the like.
  • the synthetic resin film (backside coating) arranged on the paper side opposite the photosensitive layers can be pigmented or unpigmented and / or contain other additives which result from the respective use of the laminate as a photographic support and which can in principle correspond to those of the front side coating.
  • the front coating can also contain additional functional layers which, for example, improve the adhesion of the light-sensitive layers.
  • the backside coating can also be provided with further functional layers which improve, for example, the writeability, antistatic properties, sliding properties, flatness.
  • HDPE higher density polyethylene
  • HDPE high-molecular-weight portions of polyethylene and the auxiliary agents added for stabilization.
  • HDPE can also not be pulled out at the required machine speeds on layer thicknesses of 10 - 50 11m without leaving defects and holes in the molten film.
  • Secondary disturbances due to increased extruder temperatures are dark colored particles, which result from degraded, decomposed or burned polyethylene, while agglomerates, also called gel bodies or specks, lead to disturbances when pouring light-sensitive silver halide emulsions, which in the developed image reduce, change or completely missing places Give black or color density.
  • Stabilizers in polyethylene can influence the sensitivity of photographic layers, which often only becomes visible after a long period of storage.
  • LDPE and HDPE types and their mixtures Another disadvantage of the LDPE and HDPE types and their mixtures is that the possible content of white pigment, usually titanium dioxide, is limited to around 12% by weight if one does not want to accept drastically difficult processing conditions.
  • the object of the invention is to circumvent the disadvantages mentioned essentially by using a special type of polyethylene.
  • the object is achieved in that the photographic paper support is coated with a polyethylene (PE) produced by the high-pressure process with a density between 0.930 and 0.936 g / cm 3, alone or in admixtures with LDPE's usual density.
  • PE polyethylene
  • the high-pressure polyethylene LDPE according to the invention with a density of 0.934 g / cm 3 was extruded with a layer thickness of 30 ⁇ m on both sides onto a photo base paper of 170 g / m 2 at a machine speed of 100 m / min. applied, whereby the base paper was subjected to a weak but constant corona pretreatment.
  • a polyethylene mixture of 60% by weight LDPE with a density of 0.917 g / cm3 and 40% by weight HDPE with a density of 0.960 g / cm3 was applied under the same conditions as a comparison.
  • the mixture had a density of 0.934 g / cm3.
  • a polyolefin mixture according to the invention consisting of pure LDPE composed of 65% by weight LDPE according to the invention of 0.934 g / m3 and 35% by weight LDPE of 0.917 g / m3 density was applied to the corresponding base paper.
  • Both polyethylene mixtures had a density of 0.928 g / cm 3 .
  • Examples 5 to 8 the polyethylenes of Examples 1 to 4 were mixed with 10% by weight of rutile-type titanium dioxide and applied to the base paper under the same conditions.
  • the stated adhesion of the polyethylene film to the base paper was assessed by peeling a 10 mm wide polyethylene strip in the running direction. Grades from 1 to 5 were awarded, whereby grade 1 means very good adhesion.
  • the specified stiffness of the polyethylene-coated paper was measured according to the Scan standard. P 29:69.
