Definitions
- the invention relates to a photographic support and a coating for the back of photographic Carrier materials.
- the carrier material can be a plastic-coated paper or be a plastic film.
- the back is the Surface of the carrier material, that of the one later bearing the image Front is opposite.
- the polyolefins can Polyethylenes such as LDPE, LLDPE, HDPE, or polypropylene Mixtures of these components, but plastic films are also suitable themselves as carrier materials.
- the polyolefin-coated base papers must be used because of the other Processing have certain properties.
- minilabs have a complicated paper path with numerous transport and deflection rollers that hold the paper mechanically stress. This leads to abrasion with the Consequences of transport disruptions and rejects. It follows from this the demand for a particularly hard and abrasion resistant Back layer.
- the photosensitive Emulsions coated photographic material in the development process none from the various treatment baths Dirt particles deposited on its surface ("tar-stain"), which are in aged photographic treatment baths through oxidation and condensation processes over time form.
- a backing layer must be the photographic one Carrier materials impart the following properties such as Writeability, printability, thermal printability, Adhesive tape adhesion, abrasion resistance, antistatic finish before and after developing baths. She is not allowed to do so Dirt absorption from the tar-like oxidation products Allow developing baths.
- JP 2-168251 relates to a photographic support, the back of a polymer latex and a colloidal aluminum modified silicon dioxide one Particle diameter of 2 to 7 nm is formed.
- the Solid weight ratio polymer latex to silicon dioxide is 0.8 to 2.0.
- the polymer latex is at least through the monomers styrene and acrylic are formed, with the minimum Film formation temperature is 10 to 60 ° C.
- EP-A-0 160 912 is known, one with polyethylene coated photographic material on the back with to provide an antistatic layer consisting of a Sodium magnesium silicate, a sodium polystyrene sulfonate and certain succinic acid half-esters.
- This layer should prevent electrostatic charging and that Protect material from dirt.
- it shows one poor tape adhesion, low bath strength and unsatisfactory thermal printability.
- EP-A-0 274 017 describes a photographic support material with a backing layer which has good antistatic properties and printability, medium to good abrasion and bath strength and good adhesive tape adhesion.
- the dirt intake ( However, tar-stain ”) in various developers is too high and the thermal printability is unsatisfactory.
- the back layer of this material contains a colloidal aluminum-modified silica, an alkali salt of an organic polyacid, an aqueous dispersion of copolymers of acrylic acid alkyl ester with a free carboxyl group content of 1 up to 10 mol% and free hydroxyl groups from 0 to 20 mol% and a trifunctional aziridine as crosslinking agent.
- EP-A-0 495 314 describes photography Recording material with one arranged on the support conductive layer or antistatic layer that a water-soluble conductive polymer or a metal oxide may contain. Metal oxides are shared with one Binder used.
- the conductive water-soluble polymer according to example 1 of this document is a Vinylidene chloride / methyl acrylate / itaconic acid (83: 15: 2) copolymer.
- the material claimed in this document shows a lot good antistatic properties, the abrasion resistance and however, the printability is unsatisfactory.
- a photographic Layer support consisting of support and one on the support trained back layer
- the back layer contains a conductivity substance and a copolymer
- the copolymer from a styrene / alkylstyrene / (Meth) acrylic acid / (meth) acrylic acid alkyl ester copolymer or a mixture of different styrene / alkylstyrene / (Meth) acrylic acid / (meth) acrylic acid alkyl ester copolymers and consists of 3 to 70 mol%, in particular 5 to 40 mol% (Meth) acrylic acid, contains and a film formation temperature of at most 70 ° C.
- the back layer according to the invention can be an alkali salt an organic polyacid, especially a sodium salt a polysulfonic acid or polystyrene sulfonic acid as Conductivity included.
- the amount of alkali salt an organic polyacid in the dry layer can up Amount to 10% by weight.
- Copolymers of 75 to 95 parts of one Styrene / alkylstyrene / (meth) acrylic acid / (meth) acrylic acid alkyl ester copolymer with a (meth) acrylic acid content of 3 to 10 mol% and 25 to 5 parts of a styrene / alkylstyrene / - (meth) acrylic acid / (meth) acrylic acid alkyl ester copolymer With a (meth) acrylic acid content of 30 to 40 mol%.
- the back layer can be an oxide of a metal from the 2nd to 4th main or subgroup.
- a metal from the 2nd to 4th main or subgroup.
- metal oxides selected from the group ZnO, TiO 2 , SnO 2 , Al 2 O 3 , In 2 O 3 , MgO, BaO or mixtures thereof.
- this is Metal oxide with another metal oxide from the group of metals the 2nd to 4th main group coated and can be an in the crystal lattice of the metal oxide built in Contain dopants.
- Dopants include e.g. B. niobium, tantalum, indium, Aluminum, antimony. Particularly good results were found at Tin oxide achieved with antimony (Sb) as a dopant.
- the metal oxide can also be coated on a matrix Metal oxide or one on silica or mica particles be tin oxide or antimony oxide.
- a titanium dioxide coated with an oxide of a metal of the 4th main group which may contain a dopant.
- Acicular titanium dioxide coated with tin oxide (SnO 2 ) with antimony (Sb) is particularly suitable as a dopant.
- the diameter of the TiO 2 particles is preferably 0.05 to 0.10 ⁇ m and the particle length is 3.0 to 6.0 ⁇ m.
- the back layer according to the invention a colloidal silica, especially one aluminum modified silica with a particle size of 7 to 16 nm in an amount of up to 50% by weight, based on the dry layer.
- the modification exists preferably in exchange of a few silicon atoms Aluminum atoms.
- the back layer according to the invention can contain silicates, in particular a sodium aluminum silicate with primary particles from 10 to 20 nm in an amount of up to 7% by weight, based on the dry layer.
- silicates in particular a sodium aluminum silicate with primary particles from 10 to 20 nm in an amount of up to 7% by weight, based on the dry layer.
