Definitions
- the present invention relates to photographic film supports having improved anchoring layers for water permeable colloid layers, and more particularly to cellulose film supports having polycarbonate sublayers.
- thermoplastic polycarbonates of high molecular weight especially those derived from di-(monohydroxyaryl) alkanes,'are very suitable for improving the resistance to breakage without showing the disadvantages of the other processes.
- X is selected from thegroup consisting of monovalent cycloaliphatic and aromatic hydrocarbon fying the bonding layer that the maintenance of an adequate bonding effect is coupled with improved resist-
- R R and R standing for the same or for different radicals.
- - Preferred polycarbonates are such in which R"s are hydrogen atoms and Rs are aliphatic or cycloaliphatic hydrocarbon residues of the kind mentioned above, whereby the two R's may be the same or different members of action is very quickly produced.
- the emulsion When subjected to mechanical stress, the emulsion lifts from the film material and it floats off in the photographic baths.
- intermediate layers the polarity of whichconforms better to the gelatine than the acetyl cellulose, so that they can be provided with a gelatine anchoring layer without the; gelatine being firmly incorporated into the, surface of. the intermediate layer.
- the intermediate layer can be so applied that the fracture of the emulsion layer is taken up at the boundary surface between the intermediate layer and support.
- nitrocellulose lacquer intermediate layers has been proposed, it being known that these can be coated without additives with weakly acting solvents containing gelatine.
- nitrocellulose is however not desirable owing to the fact that it is readily inflammable.
- each R represents a hydrogen atom or the same or a different member of the groups mentioned above and each R represents a member of the group consisting of the methyl, the ethyl, the propyl, the isopr'opyl, the n-butyl, the tert. butyl, the isobutyl, the tert. amyl, thecyc'lopentyl, the cyclohexyl, and the phenyl being hydrogen.
- each R is the same or Under these polycarbonates typical representatives are for instance the poly-(2,2-(4,4-dihydroxy-diphenylen)- propane-carbonate), the poly (2,2 (4,4-dihydroxy-diphenylen)-butane-carbonate), the poly-(2,2-(4,4'-dihydroxydiphenylen)-pentane-carbonate), the poly-(1,1-(4, 4'-dihydroxydiphenylen)-cyclohexane-carbonate), and the mixed poly (2,2 (4,4'-dihydroxy-diphenylen)-propaneand (4,4-dihydroxy-diphenylen)methane-carbonate).
- Aliphatic dihydroxy compounds such as: ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, thiodiglycol, ethylene dithiodiglyeol, the di-, and polyglycols produced from propyleneoxide-l,2, o, m, or p-xylylene glycol, propanediol-1,3, butanediol-1,3, butanediol-l,4, 2-methylpropanediol-L3, pentanediol-l,5, 2-ethylpropanediol-l,3, hexanediol-1,6, octanediol-1,8, l-ethylhexane diol-l,3, and decanediol-l,l0, cycloaliphatic dihydroxy compounds such as cyclohexanediol-l,4, cyclohexanediol-1,2, 2,2-(
- the aryl residues can be the same or different.
- the aryl residues can furthermore carry hydrogen atoms or substituents which are incapable of taking part in the reaction to polycarbonates, e.g. the halogens and alkyl groups such as ethyl, methyl, propyl or tertiary butyl.
- dihydroxydiaryl sulphones of the specified type the following may be mentioned:
- dihydroxy compounds which may be used in admixture with the dihydroxydiaryl sulphones if desired, there may be mentioned the following: ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, the corresponding thioglycols, di- 01' poly-glycols obtained from propylene oxide-1,2, propanediol-l,2, propanediol-l,3, butanediol-1,3, butanediol-1,4, 2-methylpropanediol-1,3, pentanediol-l,5, 2-ethylpropanediol-l,3, hexanediol-l,6, octanediol-1,8, 2-ethylhexanediol-l,3 and decanediol-l,l0; cyclohexanediol-l,4, cyclohexanediol-l,
- Di-monohydroxyarylalkanes as disclosed in copending application Serial No. 577,362, filed April 4, 1956, and in British specification No. 772,627, such as di-(p-hydroxyphenyl)-methane, 2,2- di-(p-hydroxyphenyl)-propane, 1,1-di-(p-hydroxyphenyl)- cyclohexane, l,1-di-(p-hydroxy-m-methylphenyl) cyclohexane, 2,2 di (o-hydroxy-p-tert.-butylphenyl) -propane and 3,4-di-(p-hydroxy-phenyl)-hexane and 1,1-di-(p-hydroxy-phenyl) 1 phenyl-ethane, furthermore methane derivatives which carry besides two hydroxylaryl groups, a further alkyl residue with at least two, and a second alkyl residue with one or more carbon atoms, e.g.
- 2,2-di- (p-hydroxyphenyl) -butane 2,2 di (p-hydroxyphenyD- pentane, 3,3-di-(p-hydroxyphenyl)-pentane, 2,2-d1-(p-hydroxyphenyl)-2-methylbutane, 2,2-di-(p-hydroxy-phenyl)- hexane, 2,2-di-(p-hydroxyphenyl)-4-methylpentane, 2,2- di (p hydroxyphcnyl)-heptane, 4,4-(p-hydroxyphenyl)- heptane and 2,2-di-(p-hydroxyphenyl)tridecane.
- the polyesters may be produced it, for example, bischloro-carbonates of dihydroxy diaryl sulphones or mixture thereof with the aforementioned dihydroxy com pounds, "are condensed with dihydroxy diaryl sulphones, or mixtures thereof with other dihydroxy compounds. These condensations are suitably brought about in the presence of inert solvents and acid-binding agents such as tertiary amines as described for analogous processes in British specification No. 772,627.
- a further method of carrying out the process consists in passing phosgene either into an aqueous alkali solution or suspension of the dihydroxy diaryl sulphone, optionally in the presence of other dihydroxy compounds and inert solvents, or into a solution or suspension of these materials in an inert solvent optionally in the pres ence of acid-binding agents such as tertiary amines also as described for analogous processes in British specification No. 772,627. According to both methods of carrying out the process it is an advantage to accelerate the polycondensation by adding to the reaction mixture quaternary ammonium compounds in the form of their free bases or as salts.
- the polycarbonates by inter-esterifying dihydroxy diaryl sulphones, optionally mixed with the aforementioned dihydroxy compounds and suitably in the presence of acidic or basic catalysts, with dialkyl or diaryl carbonates.
- the basic catalysts preferably used are suitably neutralized in the course of, or at the end of, the polycondensation by adding base-binding substances are especially suitable since an excess thereof can be removed by evaporation or sublimation from the melt.
- the aryl radicals may further carry substituents which are incapable of reacting during the conversion into the poly-carbonates such as halogen, or alkyl groups such as the methyl-, ethyl-, propylor the tert. butyl group.
- Suitable dihydroxy-diaryl ethers or -thioethers are, for example:
- the further dihydroxy compound which may be used in combination with the said ethers and thioethers may be the same as those disclosed above in connection with the production of polycarbonates derived from diaryl sulfones.
- the polycarbonates produced from the above ethers and thioethers or mixtures of said compounds with further dihydroxy compounds may be produced by the same methods as the polycarbonates derived from diarylsulphones and mixtures of said sulphones with further dihydro compounds.
- aromatic dihydroxy compounds derived from mixtures of aliphatic and/or cycloaliphatic dihydroxy compounds with aromatic dihydroxy compounds other than the above dihydroxy diarylalkanes, dihydroxydiarylsulfones, and dihydroxydiarylethers and -thioethers there may be used the following aromatic dihydroxy compounds:
- ethylene glycol diethylene glycol, triethylene glycol, polyethylene glycol, thiodiglycol, ethylene dithiodiglycol, propane diol-1,2, propanediol-l,3, butanediol-1,3, butanediol-1,4, 2-methylpropanediol-1,3, pentanediol-1,5, 2-ethylpropanediol-1,3, hexanediol-1,6, octanediol-1,8, 2-ethylhexanediol-l,3, decanediol-1,l0, cyclohexanediol-1,4, cyclohexanediol-1,2- 0-, mor p-xylylene glycol, 2,2'-(4,4- dihydroxydichlorohexyl)-prop
- polycarbonates derived from the disclosed sulphones, ethers and thioethers may be represented by way of example by the following formula:
- R stands for one of the following bivalent radicals: SOFQ G G G O the phenyl radicals of which may be substituted and n stands for a whole number preferably greater than 10.
- the mixed polycarbonates may contain the following units:
- the polycarbonates may also be produced by the processes indicated in the following patents: British Patent 772,627; French Patents 1,149,261; 1,152,155; 1,152,156; 1,152,157; 1,152,158; Belgian Patents 546,375; 555,894.

- the intermediate polycarbonate layer must have a certain minimum thickness, since otherwise the preparation penetrates in spite of the slight attacking action, and this results in poor bonding and also in lower resistance to breakage.
- the aforementioned additional layer of gelatine and a polymer containing hydroxyl groups preferably consists essentially of gelatine and a partially hydrolysed copolymer of 40 to 60 parts by weight of vinyl chloride and 60 to 40 parts by weight of an organic vinyl ester, such as vinylacetate, vinylpropionate, vinylbutyrate, vinyl benzoate, this copolymer advantageously containing from 45 to 70% by Weight of vinyl chloride, 530% by weight of vinyl hydroxide and 10 to 40% by weight of organic vinyl ester.
- the proportion of gelatine with respect to the copolymer can fluctuate within Wide limits; it is however advantageous to use a ratio of 2:3 parts by weight of gelatine to 3:2 parts of copolymer.
- the aforementioned mixed acetals can be obtained bya conventional process, for example by heating the components for several hours in methanolic solution with sulphuric acid as catalyst.
- aldehydes with water-solubilizing groups are aromatic aldehydes which are substituted in the aromatic nucleus by carboxyl, sulphonic acid or hydroxy groups, for example benzaldehyde-Z-sulphonic acid, benzaldehyde-2,2-disulphonic acid and p-hy- -droxy benzaldehyde.
- the acid groups may be neutralized with bases capable of yielding water-soluble salts such as alkali metals (sodium, potassium, lithium) ammonia, amines such as primary, secondary and tertiary methyl-, ethyl-, propylamines, cyclohexylamine, morpholine, piperidine.
- bases capable of yielding water-soluble salts such as alkali metals (sodium, potassium, lithium) ammonia, amines such as primary, secondary and tertiary methyl-, ethyl-, propylamines, cyclohexylamine, morpholine, piperidine.
- the mixed acetals are preferably dissolved in a proportion of 0.75 to 1.25% in a mixture of methanol and one or more other organic solvents, for example acetone, tetrahydrofurane or dioxane.
- a partially saponified copolymer of vinyl chloride and an organic vinyl ester for example vinyl acetate, vinyl propionate or vinyl butyrate, for example a paritially saponified copolymer of vinyl chloride and vinyl acetate.
- organic vinyl ester for example vinyl acetate, vinyl propionate or vinyl butyrate
- a paritially saponified copolymer of vinyl chloride and vinyl acetate are produced by known methods by saponification in methanol solution with sulphuric acid as catalyst, merely the organic ester groups being partially saponified.
- Suitable saponified copolymers contain approximately 45- 70% by weight of vinyl chloride, 30% by weight of vinyl hydroxide and -40% by weight of vinyl acetate or another organic vinyl ester such as vinyl propionate, vinyl butyrate or vinyl benzoate.
- Copolymers of vinyl chloride and e s-unsaturated carboxylic acids or partially saponified copolymers of vinyl chloride and esters of the aforementioned acids can alternatively be used.
- the coating is advantageously produced by one of the conventional dipping processes.
- Example 1 An acetyl cellulose film (61.0% acetic acid) is treated with the following base or substrate solution by the dipping process:
- the film is thereafter provided with a gelatino silver halide emulsion layer having a thickness of 8 to 18 microns.
- the resistance to breaking is good; the bonding effect is adequate. It is true that the emulsion breaks at low relative air humidities, but the breakage is not transferred to the support.
- the layer is dried at 90-1 10 C. and subbed with the following solution:
- the film support After being dried, the film support is cast with a gelatino silver halide emulsion. It has the same properties as in Example 1.
- Example 3 A film support of acetyl cellulose (57% combined acetic acid) has applied thereto an intermediate layer consisting of the following solution:
- the film support cast with photographic emulsion has the properties indicated in Example 1.
- Example 4 An acetyl cellulose film support has applied thereto an intermediate layer from the following solution:
- the film support cast with a gelatino silver halide emulsion has the properties indicated in Example 1.
- the aforementioned combinations may not only be used for treating cellulose acetate films but also film supports of other organic cellulose esters such as cellulose acetate-butyrate, cellulose acetate-propionate.
