Definitions
- the invention relates to a waterproof coated paper support for photographic layers.
- paper coated with polyolefin on both sides as a waterproof support material for photographic layers.
- a carrier material is known to consist of a sized base paper with synthetic resin coatings applied to both surfaces.
- the synthetic resin coatings can consist of polyolefin and have been applied to the paper by means of extrusion coating.
- Papers coated on both surfaces with a polyolefin resin are protected against the ingress of water and aqueous processing solutions for photographic materials: only the open edges of the laminates allow aqueous processing solutions to penetrate into the paper core, because the pulp fibers of the paper core, which are naturally hydrophilic , exposed there. For this reason, the base papers for a synthetic resin coating are usually sized to be extremely hydrophobic in order to keep the penetration of the photographic processing solutions as low as possible.
- Known glues for photographic base papers that are highly hydrophobic for the paper are dimeric alkyl ketene. These dimerized alkyl ketenes are generally used in the neutral pH range together with cationic retention agents or strengthening resins and at least partially react with superficial OH groups of the cellulose fibers. (J.Appl.Photographic Engineering 3 (1981), Issue 7, pp.68 / 69) It is also possible to use dimeric alkylketenes together with fatty acid soaps or fatty acid anhydrides, which are precipitated with aluminum salts and fixed to the fibers to achieve an optimal glue effect will.
- alkyl ketene dimers with alkyl chains of different lengths (“mixed" alkyl ketene dimers) are usually used.
- the alkyl group contains between 12 and 18 carbon atoms, as in R.D. November 1978, communication 17516 is communicated.
- Mixed alkyl ketene dimers with 16 and 18 carbon atoms are predominantly used.
- DE-OS 33 06 768 also shows that a mixed alkyl ketene dimer with predominantly C J6 and C, 8 alkyl radicals and smaller proportions of C 2 o and more alkyl radicals is best suited, while C i4 or CJ2 alkyl radicals are less suitable are suitable to obtain a good hydrophobizing sizing of the base paper.
- DE-OS 33 06 768 more or less precisely claims the use of alkyl ketene dimers with alkyl chain compositions by the equation are defined.
- alkyl ketene dimers because of their good gluing effect, alone or in combination with other glue agents, are widely used for the production of photographic base papers for synthetic resin found stratification, they still have disadvantages that previously seemed insurmountable. This applies to all alkyl ketene dimers previously used for photographic papers.
- alkyl ketene dimer does not fully react as it passes through the paper mixture. In practice, only a small part reacts with OH groups of the pulp. A larger part of the alkyl ketene dimer added to the pulp suspension for sizing is not chemically, but only physically bound in the paper fleece and therefore does not develop its full hydrophobic effect. This physically bound part consists partly of ketone, but partly of unreacted alkyl ketene dimer (Wochenblatt für Textilfabrikation 1983, p.215 f). In order to compensate for this low degree of reaction, the practice in the production of photographic base papers is carried out with additions of alkyl ketene dimer of 0.5 to 0.7% by weight, based on pulp. This amount is significantly higher than would theoretically be necessary to make the fibers hydrophobic if the reaction with OH groups described in the literature were to proceed faster and more completely.
- Another disadvantage is that because of the large proportion of physically bound alkyl ketene dimer in the paper, the hydrogen bond between the cellulose fibers (fiber-fiber bond) is disturbed and the internal strength and rigidity of the paper are reduced as a result.
- unreacted alkyl ketene dimer migrates to the paper surface during a short storage period of the paper, accumulates there and malfunctions in the subsequent application of synthetic resin layers, e.g. Polyolefin layers.
- the accumulation of the unreacted alkyl ketene dimer (dust) on the surface of the paper can be so strong that deposits of alkyl ketene dimer occur on the rolls and rollers of the coating unit during extrusion coating with polyolefin.
- rolls that come into contact with uncoated paper must be cleaned up to several times a day.
- the base paper is sized with an alkyl ketene dimer, which is predominantly formed from behenyl ketene.
- the paper core is preferably sized with an alkyl ketene dimer which consists of at least 60% behenyl ketene dimer with C 2 o-alkyl residues and has a maximum of 40% alkyl residues derived from shorter-chain fatty acids than C 20 .
- Papers produced according to the invention using a behenyl ketene dimer with more than 60% C 20 alkyl radicals did not show the disadvantages set out in the description of the prior art.
- the papers according to the invention showed neither a blooming of alkyl ketene dimer (dust) nor disproportionate disturbances in the subsequent coating with polyolefin and with photographic layers. Above all, there were no adhesion problems and no wetting problems due to the transfer of alkyl ketene dimer to the polyolefin surface.
- Papers according to the invention showed an excellent sizing effect even with smaller additions of behenyl ketene dimer than previously customary for the pulp suspension and thus a low edge penetration of photographic treatment solutions.
- the alkylketene dimer essentially containing behenyl chains is added to the pulp suspension in the form of an aqueous emulsion.
- the amount of alkyl ketene dimer to be added, based on the pulp, is between 0.1 and 1.0% by weight in the product according to the invention.
- alkyl ketene dimer with at least 60% of C2o-alkyl chains is between 0.2 and 0.7% by weight, based on the paper stock.
- the base paper can contain the known cationic resins such as polyamide-epichlorohydrazine resin, polyacrylamide or starch derivatives. It can contain a combination of cationic and anionic resins, such as in DE-OS 33 28 463, DE-OS 32 10 621 or DE-OS 32 16 840 described, and it may contain additional other sizes such as soaps of higher fatty acids, fatty acid anhydrides or epoxidized higher fatty acid amides.
- the additives customary in photographic base papers such as pigments, fillers, dyes and optical brighteners, can be present in the paper in the known amounts.
- the finished, usually also surface-sized base paper is coated on both sides with synthetic resin, e.g. with polyolefin, extrusion-coated and used as a base material for photographic layers.

- a paper was produced under the conditions described in Example 5, but the alkyl ketene dimer was a product based on palmitic / stearic acid.
- the fabric was sized with 0.7% by weight alkyl ketene dimer and 0.7% by weight polyamide-polyamine-epichlorohydrin and produced on the paper machine, the impregnating liquid from Example 1 being applied in the amount specified there using the size press.
- Part of the 170 g / m2 heavy base paper was extrusion coated on both sides with 30 g / m 2 polyethylene.
- the composition of the alkyl ketene dimers used was as follows:
- the internal strength of the base papers was determined using the Scott Bond gap strength tester (Internal Bond Impact Tester Model B) according to TAPPI RC 308.
- the stiffness values of the base papers were determined with the bending stiffness tester from Lorentzen & Wettre, Sweden, according to standard SCAN-P 29.69 and converted to specific stiffness.
- the coated papers were scratched on the surface with a razor blade so that the polyethylene could be peeled off in 25 mm wide strips.
- the force required for pulling was measured with an Alwetron TH 1 tensile testing machine (Lorentzen & Wettre, Sweden).
- the base papers produced according to the invention are preferably coated on both sides with polyolefin resin layers in order to produce the waterproof backing papers for photographic layers, as described in US Pat.
- the resin-coated paper supports are then, if appropriate after pretreatment and application of further auxiliary layers, coated in a known manner with black / white or color photographic layers.
