Definitions
- the invention relates to the production of a multilayer photographic material with an intermediate layer which contains certain polymer particles.
- photographic recording materials which consist of several layers can often not be produced in one operation, but that the layers are applied to the support material in at least two operations. You can apply single layers as well as layers of layers from several layers in one step.
- the top layer of each layer package applied in one operation usually contains a hydrophilic binder, for example gelatin, a wetting agent and, if appropriate, alkali, a plasticizer, dyes and colloidal silver.
- the photographic materials are dried and wound up before they are provided with the next shift or the next shift package.
- the rolled-up semi-finished products tend to stick to one another and thus cause stains on the recording material.
- matting agents in intermediate layers with acid-treated gelatin, which are the top layers during production, the matting agent being water-insoluble organic or inorganic materials with a particle size of approximately 0.2 to 5 ⁇ m. Since there are differences in the refractive index between these particles and the gelatin, there is increased light scattering on this particle, which leads to increased granularity (DE-A-2 526 970).
- the invention is therefore based on the object of developing intermediate layers in which the adhesion of the top layer of a first coating step when all layers are applied is avoided in at least two coating steps and also the static layer Friction is reduced.
- a process has now been found for producing a multilayer photographic material, in which the layers are applied in at least two work steps and the material is dried and wound up between the work steps, in which the aforementioned disadvantages are avoided, which is characterized in that the top layer of the first of two successive operations contains alkali-soluble polymer particles with an average particle diameter of 0.2 to 5.0 microns.
- the particle diameter is preferably 0.5 to 3.0 ⁇ m.
- compositions are selected so that the particles are insoluble in water at pH below 5 and soluble in water at pH above 7.
- the layer containing the alkali-soluble polymer particles can also contain conventional additives such as hydrophilic binders, for example gelatin, preferably alkaline-ashed gelatin, wetting agents, preferably surface-active organic fluorine compounds, formalin scavengers, plasticizers, colloidal silver and dyes.
- hydrophilic binders for example gelatin, preferably alkaline-ashed gelatin, wetting agents, preferably surface-active organic fluorine compounds, formalin scavengers, plasticizers, colloidal silver and dyes.
- the polymer particles are usually applied in an amount of 20 to 200 mg / m2 of photographic material, in particular 50 to 120 mg / m2 of photographic material. They are added to the corresponding casting solution as an aqueous dispersion.
- the addition of the polymer particles mentioned avoids the adhesive spots, a reduction in the static coefficients of friction and a reduction in the exposures caused by static discharges, the photographic properties of the multilayer photographic material, in particular grain size and sharpness, not being influenced.
- the method according to the invention can be used for the production of all multilayer photographic materials, in which the layers are applied in at least two work steps, for example for the production of negative and reversal films and photo paper, but in particular for color negative film and color reversal film. If the layers are applied in more than two work steps, the measure according to the invention can be used several times.
- the photographic materials produced according to the invention can be exposed in the manner customary for them and processed using the processes customary for this.
- the alkali-soluble matting agents to be used according to the invention are dissolved out of the photographic material by the alkaline developers, so that it thereafter light scatter from these particles can no longer occur due to different refractive indices of polymer and gelatin. Surprisingly, no pores remain in the material, which in turn could cause negative effects.
- Photographic, in particular color photographic, recording materials to which the method of the present invention can advantageously be applied are preferably multilayer materials which have a plurality of silver halide emulsion layers or emulsion layer units with different spectral sensitivity.
- Emulsion layer units are understood to mean laminates of 2 or more silver halide emulsion layers of the same spectral sensitivity.
- Layers of the same spectral sensitivity do not necessarily have to be arranged adjacent to one another, but can also be separated from one another by other layers, in particular also by layers of different spectral sensitivity.
- the binder in these layers is usually a protein-like binder with free carboxyl groups and free amino groups, preferably gelatin.
- the layered binder can contain up to 50% by weight of non-proteinaceous binders such as polyvinyl alcohol, N-vinylpyrrolidone, polyacrylic acid and their derivatives, in particular copolymers, or cellulose derivatives.
- non-proteinaceous binders such as polyvinyl alcohol, N-vinylpyrrolidone, polyacrylic acid and their derivatives, in particular copolymers, or cellulose derivatives.
- the light-sensitive silver halide emulsion layers or emulsion layer units is at least one coloring compound, usually assigned a color coupler, which is able to react with color developer oxidation products to form a non-diffusing dye.
- the color couplers are expediently non-diffusing and accommodated in the light-sensitive layer itself or in close proximity to it.
- the color couplers assigned to the two or more partial layers of an emulsion layer unit do not necessarily have to be identical. They are only intended to give the same color in color development, usually a color that is complementary to the color of the light to which the photosensitive silver halide emulsion layers are sensitive.
- the red-sensitive silver halide emulsion layers are consequently assigned at least one non-diffusing color coupler for producing the blue-green partial color image, usually a coupler of the phenol or ⁇ -naphthol type.
- a coupler of the phenol or ⁇ -naphthol type usually a coupler of the phenol or ⁇ -naphthol type.
- Particularly noteworthy are, for example, cyan couplers as described in US-A 2,474,293, US-A 2,367,531, US-A-2,895,826, US-A 3,772,002, EP-A-0 028 099, EP- A-0 112 514.
- the green-sensitive silver halide emulsion layers contain at least one non-diffusing color coupler for producing the purple partial color image, color couplers of the 5-pyrazolone or indazolone type usually being used. Cyanoacetyl compounds, oxazolones and pyrazoloazoles are also suitable as magenta couplers. Of particular note are, for example, purple couplers as described in US-A-2 600 788, US-A-4 383 027, DE-A-1 547 803, DE-A 1 810 464, DE-A 24 08 665, DE-A- 32 26 163.
- the blue-sensitive silver halide emulsion layers contain at least one non-diffusing color coupler for producing the yellow partial color image, usually a color coupler with an open-chain ketomethylene grouping.
- Yellow couplers as described in US-A-3 408 194, US-A-3 933 501, DE-A-23 29 587, DE-A-24 56 976, are particularly noteworthy.
- Color couplers of these types are known in large numbers and are described in a large number of patents. Examples include the publications “Color Coupler” by W. Pelz, “Messages from the Research Laboratories of AGFA, Leverkusen / Kunststoff", Volume III (1961) p. 111, and by K. Venkataraman in “The Chemistry of Synthetic Dyes” , Vol. 4., 341 to 387, Academic Press (1971).
- the color couplers can be 4-equivalent couplers, but also 2-equivalent couplers.

Description
Die Erfindung betrifft die Herstellung eines mehrschichtigen fotografischen Materials mit einer Zwischenschicht, die bestimmte Polymerteilchen enthält.The invention relates to the production of a multilayer photographic material with an intermediate layer which contains certain polymer particles.
Es ist bekannt, daß fotografische Aufzeichnungsmaterialien, die aus mehreren Schichten bestehen, oft nicht in einem Arbeitsgang hergestellt werden können, sondern daß die Schichten in mindestens zwei Arbeitsgängen auf das Trägermaterial aufgebracht werden. Dabei kann man in einem Arbeitsgang sowohl Einzelschichten als auch Schichtpakete aus mehreren Schichten aufbringen. Die oberste Schicht eines jeden in einem Arbeitsgang aufgebrachten Schichtpaketes enthält üblicherweise einen hydrophilen Binder, beispielsweise Gelatine, ein Netzmittel sowie gegebenenfalls Alkali, einen Weichmacher, Farbstoffe und kolloidales Silber.It is known that photographic recording materials which consist of several layers can often not be produced in one operation, but that the layers are applied to the support material in at least two operations. You can apply single layers as well as layers of layers from several layers in one step. The top layer of each layer package applied in one operation usually contains a hydrophilic binder, for example gelatin, a wetting agent and, if appropriate, alkali, a plasticizer, dyes and colloidal silver.
Nach jedem Arbeitsgang werden die fotografischen Aufzeichnungsmaterialien getrocknet und aufgewickelt, bevor sie mit der nächsten Schicht oder dem nächsten Schichtpaket versehen werden. Die aufgerollten Halbfabrikate neigen dazu, aneinander zu kleben und so Flecken auf dem Aufzeichnungsmaterial zu verursachen.After each operation, the photographic materials are dried and wound up before they are provided with the next shift or the next shift package. The rolled-up semi-finished products tend to stick to one another and thus cause stains on the recording material.
Es ist bekannt, bei einem fertigen Film diesen unerwünschten Effekt dadurch zu vermeiden, daß man in die oberste Schicht sogenannte Abstandshalter oder Mattierungsmittel einbringt, d.h., feste Partikel mit einem mittleren Teilchendurchmesser von mindestens 1 µm (DE-A 2 758 767, EP-A 0 167 081). Diese Maßnahme kann im allgemeinen für die oberen Schichten eines Arbeitsganges, die später Innenschichten sind, nicht getroffen werden, da dies zu Schleierbildung, Unebenheiten beim Beguß und Verschlechterung der Bruchfestigkeit führen kann.It is known to avoid this undesirable effect in a finished film by introducing so-called spacers or matting agents into the top layer, ie solid particles with an average particle diameter of at least 1 μm (DE-A 2 758 767, EP-A 0 167 081). This measure can generally not be taken for the upper layers of an operation, which are later the inner layers, since this can lead to the formation of fog, unevenness in the casting and deterioration of the breaking strength.
Es wurde auch schon vorgeschlagen, Mattierungsmittel in Zwischenschichten mit säurebehandelter Gelatine, die während der Herstellung oberste Schichten sind, einzubringen, wobei als Mattierungsmittel in Wasser nicht lösliche organische oder anorganische Materialien mit einer Teilchengröße von etwa 0,2 bis 5 µm in Frage kommen. Da Unterschiede im Brechnungsindex zwischen diesen Teilchen und der Gelatine bestehen, kommt es zu vermehrter Lichtstreuung an diesem Teilchen, was zu erhöhter Körnigkeit führt (DE-A-2 526 970).It has also been proposed to incorporate matting agents in intermediate layers with acid-treated gelatin, which are the top layers during production, the matting agent being water-insoluble organic or inorganic materials with a particle size of approximately 0.2 to 5 μm. Since there are differences in the refractive index between these particles and the gelatin, there is increased light scattering on this particle, which leads to increased granularity (DE-A-2 526 970).
Der Erfindung liegt somit die Aufgabe zugrunde, Zwischenschichten zu entwickeln, bei denen das Kleben der obersten Schicht eines ersten Beschichtungsganges bei Aufbringung sämtlicher Schichten in wenigstens zwei Beschichtungsgängen vermieden und außerdem die statische Reibung reduziert wird, Dabei sollen die übrigen filmtechnologisch wichtigen Eigenschaften, insbesondere die sensitometrischen Eigenschaften, nicht nachteilig beeinflußt werden.The invention is therefore based on the object of developing intermediate layers in which the adhesion of the top layer of a first coating step when all layers are applied is avoided in at least two coating steps and also the static layer Friction is reduced. The other properties important in terms of film technology, in particular the sensitometric properties, should not be adversely affected.
Es wurde nun ein Verfahren zur Herstellung eines mehrschichtigen fotografischen Materials, bei dem die Schichten in wenigstens zwei Arbeitsgängen aufgebracht werden und das Material zwischen den Arbeitsgängen getrocknet und aufgewickelt wird, gefunden, bei dem die vorbezeichneten Nachteile vermieden werden, das dadurch gekennzeichnet ist, daß die oberste Schicht des ersten von zwei aufeinanderfolgenden Arbeitsgängen alkalilösliche Polymerteilchen eines mittleren Teilchendurchmessers von 0,2 bis 5,0 µm enthält.A process has now been found for producing a multilayer photographic material, in which the layers are applied in at least two work steps and the material is dried and wound up between the work steps, in which the aforementioned disadvantages are avoided, which is characterized in that the top layer of the first of two successive operations contains alkali-soluble polymer particles with an average particle diameter of 0.2 to 5.0 microns.
Vorzugsweise ist der Teilchendurchmesser 0,5 bis 3,0 µm.The particle diameter is preferably 0.5 to 3.0 μm.
Als geeignete alkalilösliche Polymerteilchen kommen solche der folgenden chemischen Klassen in Frage:
- 1. Copolymerisate von Alkylmethacrylaten mit Methacrylsäure, Acrylsäure oder Itaconsäure.
- 2. Copolymerisate von Alkylmethacrylaten mit Maleinsäurehalbestern oder Maleinsäurehalbamiden.
- 3. Copolymerisate von Styrol mit α,β-ungesättigten Mono- oder Dicarbonsäuren, Dicarbonsäurehalbestern oder Dicarbonsäurehalbamiden.
- 4. Pfropfpolymerisate von Methacrylsäure/Methylmethacrylat auf wasserlösliche Dispergatoren von Maleinsäureanhydrid und α-Olefin.
- 5. Cellulosederivate von Dicarbonsäurehalbestern, z. B. Phthalate und Hexahydrophthalat von Methylcellulose, Hydroxyethylmethylcellulose oder Hydroxypropylmethylcellulose.
- 1. Copolymers of alkyl methacrylates with methacrylic acid, acrylic acid or itaconic acid.
- 2. Copolymers of alkyl methacrylates with maleic acid half-esters or maleic acid halamides.
- 3. Copolymers of styrene with α, β-unsaturated mono- or dicarboxylic acids, dicarboxylic acid half-esters or dicarboxylic acid halamides.
- 4. Graft polymers of methacrylic acid / methyl methacrylate on water-soluble dispersants of maleic anhydride and α-olefin.
- 5. Cellulose derivatives of dicarboxylic acid half-esters, e.g. B. phthalates and hexahydrophthalate of methyl cellulose, hydroxyethyl methyl cellulose or hydroxypropyl methyl cellulose.
Die Zusammensetzungen werden so ausgewählt, daß die Teilchen bei pH-Werten unter 5 in Wasser unlöslich und bei pH-Werten über 7 in Wasser löslich sind.The compositions are selected so that the particles are insoluble in water at pH below 5 and soluble in water at pH above 7.
Die die alkalilöslichen Polymerteilchen enthaltende Schicht kann außerdem übliche Zusätze wie hydrophile Binder, beispielsweise Gelatine, vorzugsweise alkalisch geäscherte Gelatine, Netzmittel, vorzugsweise grenzflächenaktive organische Fluorverbindungen, Formalinfänger, Weichmacher, kolloidales Silber und Farbstoffe enthalten.The layer containing the alkali-soluble polymer particles can also contain conventional additives such as hydrophilic binders, for example gelatin, preferably alkaline-ashed gelatin, wetting agents, preferably surface-active organic fluorine compounds, formalin scavengers, plasticizers, colloidal silver and dyes.
Die Polymerteilchen werden üblicherweise in einer Menge von 20 bis 200 mg/m² fotografischen Materials, insbesondere 50 bis 120 mg/m² fotografischen Materials, aufgebracht. Sie werden der entsprechenden Gießlösung als wäßrige Dispersion zugesetzt.The polymer particles are usually applied in an amount of 20 to 200 mg / m² of photographic material, in particular 50 to 120 mg / m² of photographic material. They are added to the corresponding casting solution as an aqueous dispersion.
Überrraschenderweise wird durch den Zusatz der genannten Polymerteilchen eine Vermeidung der Klebeflecken, eine Reduzierung der statischen Reibwerte und eine Reduzierung der durch statische Entladungen verursachten Belichtungen erreicht, wobei die fotografischen Eigenschaften des mehrschichtigen fotografischen Materials, insbesondere Körnigkeit und Schärfe, nicht beeinflußt werden.Surprisingly, the addition of the polymer particles mentioned avoids the adhesive spots, a reduction in the static coefficients of friction and a reduction in the exposures caused by static discharges, the photographic properties of the multilayer photographic material, in particular grain size and sharpness, not being influenced.
Das erfindungsgemäße Verfahren kann für die Herstellung aller mehrschichtigen fotografischen Materialien verwendet werden, bei dem die Schichten in wenigstens zwei Arbeitsgängen aufgebracht werden, beispielsweise für die Herstellung von Negativ- und Umkehrfilmen sowie Fotopapier, insbesondere aber für Colornegativfilm und Colorumkehrfilm. Werden die Schichten in mehr als zwei Arbeitsgängen aufgebracht, kann von der erfindungsgemäßen Maßnahme mehrfach Gebrauch gemacht werden.The method according to the invention can be used for the production of all multilayer photographic materials, in which the layers are applied in at least two work steps, for example for the production of negative and reversal films and photo paper, but in particular for color negative film and color reversal film. If the layers are applied in more than two work steps, the measure according to the invention can be used several times.
Die erfindungsgemäß hergestellten fotografischen Materialien können in der für sie üblichen Weise belichtet und mit den dafür gebräuchlichen Verfahren verarbeitet werden.The photographic materials produced according to the invention can be exposed in the manner customary for them and processed using the processes customary for this.
Durch die alkalischen Entwickler werden die erfindungsgemäß zu verwendenden alkalilöslichen Mattierungsmittel aus dem fotografischen Material herausgelöst, so daß es danach nicht mehr zur Lichtstreuung an diesen Teilchen wegen unterschiedlichen Brechungsindices von Polymer und Gelatine kommen kann. Überraschenderweise bleiben im Material keine Poren zurück, die ihrerseits für negative Effekte sorgen könnten.The alkali-soluble matting agents to be used according to the invention are dissolved out of the photographic material by the alkaline developers, so that it thereafter light scatter from these particles can no longer occur due to different refractive indices of polymer and gelatin. Surprisingly, no pores remain in the material, which in turn could cause negative effects.
Bei fotografischen, insbesondere farbfotografischen Aufzeichnungsmaterialien, auf die das Verfahren der vorliegenden Erfindung mit Vorteil angewendet werden kann,handelt es sich bevorzugt um mehrschichtige Materialien, die mehrere Silberhalogenidemulsionsschichten oder Emulsionsschichteneinheiten mit unterschiedlicher Spektralempfindlichkeit aufweisen. Als Emulsionsschichteneinheiten werden dabei Laminate von 2 oder mehr Silberhalogenidemulsionsschichten gleicher Spektralempfindlichkeit verstanden. Schichten gleicher Spektralempfindlichkeit müssen aber nicht notwendigerweise benachbart zueinander angeordnet sein, sondern können auch durch andere Schichten, insbesondere auch durch Schichten anderer Spektralempfindlichkeit voneinander getrennt sein. Das Bindemittel in diesen Schichten ist in der Regel ein proteinartiges Bindemittel mit freien Carboxylgruppen und freien Aminogruppen, bevorzugt Gelatine. Das Schichtbindemittel kann aber neben dem proteinartigen Bindemittel bis zu 50 Gew.-% nicht proteinartige Bindemittel wie Polyvinylalkohol, N-Vinylpyrrolidon, Polyacrylsäure und deren Derivate, insbesondere Mischpolymerisate, oder Cellulosederivate enthalten.Photographic, in particular color photographic, recording materials to which the method of the present invention can advantageously be applied are preferably multilayer materials which have a plurality of silver halide emulsion layers or emulsion layer units with different spectral sensitivity. Emulsion layer units are understood to mean laminates of 2 or more silver halide emulsion layers of the same spectral sensitivity. Layers of the same spectral sensitivity do not necessarily have to be arranged adjacent to one another, but can also be separated from one another by other layers, in particular also by layers of different spectral sensitivity. The binder in these layers is usually a protein-like binder with free carboxyl groups and free amino groups, preferably gelatin. In addition to the proteinaceous binder, the layered binder can contain up to 50% by weight of non-proteinaceous binders such as polyvinyl alcohol, N-vinylpyrrolidone, polyacrylic acid and their derivatives, in particular copolymers, or cellulose derivatives.
Den lichtempfindlichen Silberhalogenidemulsionsschichten bzw. Emulsionsschichteneinheiten ist mindestens eine farbgebende Verbindung, in der Regel ein Farbkuppler zugeordnet, der mit Farbentwickleroxidationsprodukten unter Bildung eines nichtdiffundierenden Farbstoffes zu reagieren vermag. Zweckmäßigerweise sind die Farbkuppler nichtdiffundierend und in der lichtempfindlichen Schicht selbst oder in enger Nachbarschaft hierzu untergebracht. Die den zwei oder mehr Teilschichten einer Emulsionsschichteinheit zugeordneten Farbkuppler brauchen nicht notwendigerweise indentisch zu sein. Sie sollen lediglich bei der Farbentwicklung die gleiche Farbe ergeben, normalerweise eine Farbe, die komplementär ist zu der Farbe des Lichtes, gegen das die lichtempfindlichen Silberhalogenidemulsionsschichten empfindlich sind.The light-sensitive silver halide emulsion layers or emulsion layer units is at least one coloring compound, usually assigned a color coupler, which is able to react with color developer oxidation products to form a non-diffusing dye. The color couplers are expediently non-diffusing and accommodated in the light-sensitive layer itself or in close proximity to it. The color couplers assigned to the two or more partial layers of an emulsion layer unit do not necessarily have to be identical. They are only intended to give the same color in color development, usually a color that is complementary to the color of the light to which the photosensitive silver halide emulsion layers are sensitive.
Den rotempfindlichen Silberhalogenidemulsionsschichten ist folglich mindestens ein nichtdiffundierender Farbkuppler zur Erzeugung des blaugrünen Teilfarbenbildes zugeordnet, in der Regel ein Kuppler vom Phenol- oder α-Naphtholtyp. Besonders hervorzuheben sind beispielsweise Blaugrünkuppler, wie sie beschrieben sind in US-A 2 474 293, US-A 2 367 531, US-A-2 895 826, US-A 3 772 002, EP-A-0 028 099, EP-A-0 112 514.The red-sensitive silver halide emulsion layers are consequently assigned at least one non-diffusing color coupler for producing the blue-green partial color image, usually a coupler of the phenol or α-naphthol type. Particularly noteworthy are, for example, cyan couplers as described in US-A 2,474,293, US-A 2,367,531, US-A-2,895,826, US-A 3,772,002, EP-A-0 028 099, EP- A-0 112 514.
Die grünempfindlichen Silberhalogenidemulsionsschichten enthalten mindestens einen nichtdiffundierenden Farbkuppler zur Erzeugung des purpurnen Teilfarbbildes, wobei üblicherweise Farbkuppler vom Typ des 5-Pyrazolons oder des Indazolons Verwendung finden. Weiter kommen als Purpurkuppler auch Cyanacetylverbindungen, Oxazolone, und Pyrazoloazole in Frage. Besonders hervorzuheben sind beispielsweise Purpurkuppler wie sie beschrieben sind in US-A-2 600 788, US-A-4 383 027, DE-A-1 547 803, DE-A 1 810 464, DE-A 24 08 665, DE-A-32 26 163.The green-sensitive silver halide emulsion layers contain at least one non-diffusing color coupler for producing the purple partial color image, color couplers of the 5-pyrazolone or indazolone type usually being used. Cyanoacetyl compounds, oxazolones and pyrazoloazoles are also suitable as magenta couplers. Of particular note are, for example, purple couplers as described in US-A-2 600 788, US-A-4 383 027, DE-A-1 547 803, DE-A 1 810 464, DE-A 24 08 665, DE-A- 32 26 163.
Die blauempfindlichen Silberhalogenidemulsionsschichten schließlich enthalten mindestens einen nichtdiffundierenden Farbkuppler zur Erzeugung des gelben Teilfarbenbildes, in der Regel einen Farbkuppler mit einer offenkettigen Ketomethylengruppierung. Besonders hervorzuheben sind bespielsweise Gelbkuppler, wie sie beschrieben sind in US-A-3 408 194, US-A-3 933 501, DE-A-23 29 587, DE-A-24 56 976.Finally, the blue-sensitive silver halide emulsion layers contain at least one non-diffusing color coupler for producing the yellow partial color image, usually a color coupler with an open-chain ketomethylene grouping. Yellow couplers, as described in US-A-3 408 194, US-A-3 933 501, DE-A-23 29 587, DE-A-24 56 976, are particularly noteworthy.
Farbkuppler dieser Arten sind in großer Zahl bekannt und in einer Vielzahl von Patentschriften beschrieben. Beispielhaft sei hier ferner auf die Veröffentlichungen "Farbkuppler" von W. Pelz, "Mitteilungen aus den Forschungslaboratorien der AGFA, Leverkusen/München", Band III (1961) S. 111, und von K. Venkataraman in "The Chemistry of Synthetic Dyes", Vol. 4., 341 bis 387, Academic Press (1971), verwiesen.Color couplers of these types are known in large numbers and are described in a large number of patents. Examples include the publications "Color Coupler" by W. Pelz, "Messages from the Research Laboratories of AGFA, Leverkusen / Munich", Volume III (1961) p. 111, and by K. Venkataraman in "The Chemistry of Synthetic Dyes" , Vol. 4., 341 to 387, Academic Press (1971).
Bei den Farbkupplern kann es sich um 4-Äquivalentkuppler, aber auch um 2-Äquivalentkuppler handeln. Letztere leiten sich bekanntlich von den 4-Äquivalentkupplern dadurch ab, daß sie in der Kupplungsstelle einen Substituenten enthalten, der bei der Kupplung abgespalten wird. Zu den 2-Äquivalentkupplern sind sowohl solche zu rechnen, die praktisch farblos sind, als auch solche, die eine intensive Eigenfarbe aufweisen, die bei der Farbkupplung verschwindet bzw. durch die Farbe des erzeugten Bildfarbstoffes ersetzt wird (Maskenkuppler). Zu den 2-Äquivalentkupplern sind im Prinzip auch die bekannten Weißkuppler zu rechnen, die jedoch bei Reaktion mit Farbentwickleroxidationsprodukten im wesentlichen farblose Produkte ergeben. Zu den 2-Äquivalentkupplern sind ferner solche Kuppler zu rechnen, die in der Kupplungsstelle einen abspaltbaren Rest enthalten, der bei Reaktion mit Farbentwickleroxidationsprodukten in Freiheit gesetzt wird und dabei entweder direkt oder nachdem aus dem primär abgespaltenen Rest eine oder mehrere weitere Gruppen abgespalten worden sind (z.B. DE-A-27 03 145, DE-A 28 55 697, DE-A-31 05 026, DE-A-33 19 428), eine bestimmte erwünschte fotografische Wirksamkeit entfaltet, z.B. als Entwicklungsinhibitor oder- acceletator. Beispiele für solche 2-Äquivalentkuppler sind die bekannten DIR-Kuppler wie auch DAR- bzw. FAR-Kuppler.The color couplers can be 4-equivalent couplers, but also 2-equivalent couplers. As is known, the latter are derived from the 4-equivalent couplers in that they contain a substituent in the coupling site which is split off during the coupling. The 2-equivalent couplers include those that are practically colorless, as well as those that have an intense inherent color that the Color coupling disappears or is replaced by the color of the image dye generated (mask coupler). In principle, the known white couplers are also to be counted among the 2-equivalent couplers, but they essentially result in colorless products on reaction with color developer oxidation products. The 2-equivalent couplers also include those couplers that contain a cleavable residue in the coupling point, which is released upon reaction with color developer oxidation products and thereby either directly or after one or more further groups have been cleaved from the primarily cleaved residue ( eg DE-A-27 03 145, DE-A 28 55 697, DE-A-31 05 026, DE-A-33 19 428), a certain desired photographic activity unfolds, for example as a development inhibitor or accelerator. Examples of such 2-equivalent couplers are the known DIR couplers as well as DAR and FAR couplers.
Geeignete DIR-Kuppler sind beispielsweise beschrieben in GB-A-953 454, DE-A-1 800 420, DE-A 20 15 867, DE-A-24 14 006, DE-A-28 42 063, DE-A-34 27 235.Suitable DIR couplers are described, for example, in GB-A-953 454, DE-A-1 800 420, DE-A 20 15 867, DE-A-24 14 006, DE-A-28 42 063, DE-A- 34 27 235.
Geeignete DAR- bzw. FAR-Kuppler sind beispielsweise beschrieben in DE-A-32 09 110, EP-A-0 089 834, EP-A-0 117 511, EP-A-0 118 087.Suitable DAR or FAR couplers are described, for example, in DE-A-32 09 110, EP-A-0 089 834, EP-A-0 117 511, EP-A-0 118 087.
Da bei den DIR-, DAR- bzw. FAR-Kupplern hauptsächlich die Wirksamkeit des bei der Kupplung freigesetzten Restes erwünscht ist und es weniger auf die farbbildenden Eigenschaften dieser Kuppler ankommt, sind auch solche DIR-, DAR- bzw. FAR-Kuppler geeignet, die bei der Kupplung im wesentlichen farblose Produkte ergeben wie beispielsweise beschrieben in DE-A 1 547 640.Since with DIR, DAR and FAR couplers the effectiveness of the residue released during the coupling is mainly desired and the color-forming properties of these couplers are less important, are also such DIR, DAR or FAR couplers are suitable which, when coupled, result in essentially colorless products, as described, for example, in DE-A 1 547 640.
Der abspaltbare Rest kann auch ein Ballastrest sein, so daß bei der Reaktion mit Farbentwickleroxidationsprodukten Kupplungsprodukte z.B. Farbstoffe erhalten werden können, die diffusionsfähig sind oder zumindest eine schwache bzw. eingeschränkte Beweglichkeit aufweisen wie beispielsweise in US-A-4 420 556 beschrieben.The cleavable residue can also be a ballast residue, so that when reacting with color developer oxidation products coupling products e.g. Dyes can be obtained which are diffusible or at least have a weak or restricted mobility, as described, for example, in US Pat. No. 4,420,556.
Hochmolekulare Farbkuppler sind beispielsweise beschrieben in DE-C-1 297 417, DE-A-24 07 569, DE-A-31 48 125, DE-A-32 17 200, DE-A-33 20 079, DE-A-33 24 932, DE-A-33 31 743, DE-A-33 40 376, EP-A-27 284, US-A-4 080 211. Die hochmolekularen Farbkuppler werden in der Regel durch Polymerisation von ethylenisch ungesättigten monomeren Farbkupplern hergestellt. Sie können aber auch durch Polyaddition oder Polykondensation erhalten werden.High molecular weight color couplers are described for example in DE-C-1 297 417, DE-A-24 07 569, DE-A-31 48 125, DE-A-32 17 200, DE-A-33 20 079, DE-A- 33 24 932, DE-A-33 31 743, DE-A-33 40 376, EP-A-27 284, US-A-4 080 211. The high molecular weight color couplers are generally produced by polymerizing ethylenically unsaturated monomeric color couplers . However, they can also be obtained by polyaddition or polycondensation.
Über die genannten Bestandteile hinaus können die Schichten weitere Zusätze enthalten, zum Beispiel Härtungsmittel, Antioxidantien, farbstoffstabilisierende Mittel und Mittel zur Beeinflussung der mechanischen und elektrostatischen Eigenschaften. Um die nachteilige Einwirkung von UV-Licht auf die mit dem erfindungsgemäßen farbfotografischen Aufzeichnungsmaterialien hergestellten Farbbilder zu vermindern oder zu vermeiden, können die Schichten auch UV-Licht absorbierende Verbindungen enthalten.In addition to the constituents mentioned, the layers can contain further additives, for example hardening agents, antioxidants, dye-stabilizing agents and agents for influencing the mechanical and electrostatic properties. In order to reduce or avoid the disadvantageous effect of UV light on the color images produced with the color photographic recording materials according to the invention, the layers can also contain compounds absorbing UV light.

Die beschriebenen Schicht-Teilaufbauten (Schichten 1-6) wurden auf Gleiteigenschaften und Oberflächenwiderstand geprüft. Der Reibwert (Reibwert = Zugkraft/Normalkraft × 100) ist ein Maß für die Haftreibung, wenn das Material mit der Beschichtungsseite unter der Einwirkung einer Zugkraft über die Rückseite sowie Schichtseite des gleichen Materials bzw. über eine Oberfläche aus Plüsch zu gleiten beginnt.The described partial layer structures (layers 1-6) were tested for sliding properties and surface resistance. The coefficient of friction (coefficient of friction = tensile force / normal force × 100) is a measure of the static friction when the material with the coating side begins to slide under the action of a tensile force over the back and layer side of the same material or over a surface made of plush.

Die Bruchfestigkeit, Körnigkeit und Schärfe der fertigaufgebauten Schichten wurden gemessen. Außerdem wurde die Fleckenbelastung visuell beurteilt und in prozentualer Belastung ausgegeben.The breaking strength, granularity and sharpness of the finished layers were measured. In addition, the stain load was assessed visually and given in percent load.
Die Parallelbruchfestigkeit wurde durch die Parameter Bruchdurchmesser [mm] und Bruchkraft [N] charakterisiert. Hierbei wurde ein 35 mm breiter Streifen des betreffenden Materials, der längs einer Querlinie perforiert war, zu einer Schleife geformt und diese zwischen zwei parallelen, einander stetig annähernden Backen zusammengepresst. Bruchdurchmesser ist der innere Durchmesser der Schleife und Bruchkraft ist die Kraft, mit der die beiden Backen auf die Schleife einwirken, und zwar in dem Moment, wo die Schleife entlang der Perforationslinie bricht.The parallel breaking strength was characterized by the parameters breaking diameter [mm] and breaking strength [N]. Here, a 35 mm wide strip of the material in question, which was perforated along a transverse line, was formed into a loop and this was pressed together between two parallel, continuously approaching jaws. Breaking diameter is the inner diameter of the loop and breaking force is the force with which the two jaws act on the loop at the moment the loop breaks along the perforation line.
