The present invention relates to a method for producing photographic images according to the well-known ™ Silver complex diffusion transfer process "

According to a specific embodiment of this method a so-called multilayer material is used which has an image-receiving layer and a light-sensitive layer on the same support Silver halide emulsion layer contains «The light-sensitive layer can be over the image-receiving layer are present, and are removed after the transfer image generation, for example by means of a brought into contact therewith Auxiliary layer or by means of a subsequent rinsing bath in which the silver halide emulsion layer is dissolves or comes off in the form of small flakes or an f

connected membrane.

The known methods always have disadvantages in the production of one or more layers of the 'multilayer material often not usual and less suitable binders can be used. Furthermore, water often has to be used to remove the emulsion layer at about 35-5O ° C can be used. Another serious disadvantage that often occurs is the fact that the silver halide emulsion layer tends to get loose already in the alkaline processing liquid, which is what the

9098AO / 1406

Making a diffusion transfer copy lesser Quality, and thereby complicating the entire process of removing the emulsion layer.

According to the present invention, these disadvantages can be eliminated by incorporating into the light-sensitive silver halide emulsion layer and / or in a layer between this emulsion layer and an underlying image-receiving layer of a multilayer material for the production of images by the silver complex diffusion transfer process incorporates a macromolecular compound with available cishydroxy groups, and diffusion transfer imaging with an alkaline processing liquid in the presence of orthoborate ions. The light sensitive The emulsion layer can then be removed with an aqueous rinsing liquid without mechanical aid.

The present invention relates to a method for Production of photographic images by the silver complex diffusion transfer process, in which a multilayer material is used, which in the order a carrier, an image receiving layer and a photosensitive silver halide emulsion layer contains, the latter layer and / or an additional one optionally between the Emulsion layer and the image-receiving layer present Auxiliary layer a macromolecular compound with cishydroxy groups contains, and after the imagewise exposed multilayer material with an aqueous alkaline Processing liquid in the presence of orthoborate ions and after diffusion transfer imaging for removing the emulsion layer without substantial mechanical help with an aqueous rinsing liquid is treated.

Suitable macromolecular compounds with cishydroxy groups are water-soluble rubbers e.g. ■ Arabic gum, certain polysaccharides and their derivatives, such as mannans and galctomannans, alginates,

909840/1406

Pectic acid monoglyceryl ester and oxyalkyl starch or oxyalkyl celluloses, e.g. oxyethyl and oxypropyl starch, and certain synthetic substances such as partially saponified I οIyvinylacetate and polyvinyl alcohol. The available Cishydroxy groups are preferably in the 1--2 position before, but sometimes they can also be in another position, e.g. in the 1-3 position, as in the case of many Pairs of hydroxyl groups in partially or fully saponified Polyvinyl acetate. The macromolecular compound contains at least different pairs of cishydroxy groups per macromolecular chain. often two or more such types of connections are used together. The macromolecular compound for carrying out the inventive Method preferably has film-forming properties per se, m.a.W. is a binder. This is but not an essential requirement, and non-film-forming macromolecular compounds can also be used find that during the production of the material or during processing, as described in detail below will gel in situ.

If there is no additional layer between the emulsion layer and the receiving layer is present, the former contains the macromolecular compound or the macromolecular ones Links. This connection or connections represents br.w. preferably represent about 10 to about 70 wt.% the total weight of the binder of the silver halide emulsion layer Larger amounts generally impair the photographic characteristics of the Emulsion layer and are therefore mostly not used. The macromolecular compound can be photosensitive Casting composition at any moment added to the production, e.g. before the precipitation of the photosensitive silver halide or just before the Coating. When using the alkaline processing liquid to carry out the development and the diffusion transfer imaging is the silver

halide emulsion layer due to the action of orthoborate ions on the macromolecular compound in an alkaline medium in situ intensified »Afterwards the rigid gel structure in the aqueous rinsing liquid, and the emulsion dissolves or comes off in the form of smaller flakes.

In the production of the multilayer material is often at least one intermediate layer between the image receiving layer and the photosensitive silver halide emulsion layer .norderly. This intermediate layer ensures a better contact between the receiving layer and the Emulsion layer, and should also be the adhesion of the emulsion layer on the image receiving layer before or during Improve processing and facilitate the separation of the emulsion layer after processing. In practice but the emulsion layer often dissolves in the alkaline one Processing fluid, which results in contamination of the latter and image defects.

According to the present invention, this problem is completely eliminated by incorporating a macromolecular compound with available cishydroxy groups in the silver halide emulsion layer, as described in detail above, and / or incorporating a same type of compound in a layer between the receiving layer and the emulsion layer. In such an intermediate layer, the macromolecular compound with available cishydroxy groups is preferably present in an amount of at least 20% by weight of the total weight of the binder. In many cases, this macromolecular compound represents the sole and whole amount of the binder of the intermediate layer. If it does not have any film-forming characteristics per se, it can gel in situ during the production of the multilayer material, for example in an alkaline medium and by means of orthoborate ions, which in the layer composition $ , or from another layer of the multilayer material

V I

When using the alkaline processing liquid the macromolecular compound present in the intermediate layer is strengthened as described above and ensured that is, good adhesion of the emulsion layer to the image-receiving layer; Afterwards, when rinsing with the aqueous liquid, the tight gel structure of the macomolecular ones is loosened Connection and detachment of the intermediate layer, this allows the emulsion layer to come without mechanical Help go. Depending on the nature of this layer, it will also dissolve or be in the form of flakes or as a coherent one Loosen the membrane.

Suitable compounds for borating in an aqueous medium are the following water-soluble oxygen boron compounds : Orthoboric acid and its salts, metaborates, polyborates such as tetraborates, for example borax and sodium tetraborate, and pentaborates, e.g., potassium pentaborate.

There are several routes for the delivery of orthoboratlones. The borating compounds can be incorporated into at least one layer of the multilayer material, e.g. the image-receiving layer, the photosensitive silicon-overhalide emulsion layer and / or optionally another layer, e.g. an adhesive and separating layer, the between the image receiving layer and the photosensitive one Silver halide emulsion layer was placed. If If the material contains a paper support, it is also possible to use a considerable amount and even in this support incorporate all of the borating compound. Preferably an amount of about 100 mg to about 50 g borating compound is used per square meter of the multilayer material.

The present invention also relates to a multilayer material for carrying out those according to the invention Method according to which an orthoborate ion-supplying compound is present in at least one layer of the multilayer material is present.

909840/1406

Instead of or additionally incorporating this compound into the multilayer material, there is a preferred embodiment of the present invention therein, mostly a part and preferably even the whole amount of this compound of to add alkaline processing liquid to perform diffusion transfer image formation = Die Compounds supplying orthoborate ions can be used in this connection. processing fluid in an amount, preferably equivalent to from about 0.2 g to about 20 g of boric acid per Liters.

It is even possible to use the compounds that supply orthoborate ions by means of a separate liquid (a different liquid than the alkaline processing liquid) to be supplied with the photosensitive material after manufacture and before treatment with the alkaline Liquid for carrying out the development of the silver halide emulsion layer and the creation of the diffusion Transfer image is wetted »

When carrying out the method according to the invention, the Photographic multilayer material exposed imagewise according to an original »This exposure can be carried out in a Camera or in another well-known exposure device can be made.

Then the multilayer material is treated with an alkaline

Treatment liquid wetted around the silver halide emulsion layer to develop, and to complex the non-exposed silver halide and from the non-image divide the silver halide emulsion layer and allow it to diffuse over into the image receiving layer where it is is converted into a visible image.

Of course, this processing step is carried out in the presence of developing substances, a complexing agent for silver halide and orthoborate ions. The _t aqueous alkaline medium of the processing liquid

909840 / U06

remove the orthoborate ions from the borating compound free. The orthoborate ions solidify the macromolecular compound containing cishydroxy groups, which is present in the Silver halide emulsion layer and / or in an underlying layer on the image-receiving layer, by in all likelihood forming a three-dimensional structure, thereby decreasing strength the layer too, and also the adhesion of the emulsion layer at the image receiving layer improved. In this way, there is a risk of premature escape Emulsion layer turned away during the treatment with the alkaline processing liquid, and become all the resulting harmful effects are completely avoided. During the subsequent treatment with neutral or weakly acidic aqueous flushing liquid but the three-dimensional structure of the macromolecular compound containing cishydroxy groups with the borate ions torn, whereby the silver halide emulsion layer dissolves or as a coherent membrane or in the form of smaller flakes gets loose. The aqueous rinse liquid can contain a minor amount of an oxidizing agent contain, for example, a water-soluble periodate to break the bonds between the macromolecular Chains to accelerate even further. In fact, the solidification of the macro f containing cishydroxy groups takes place molecular connection through the formation of borate bonds between the chains in an alkaline medium. So that Structure generated in situ is a reversible gel, m.a.W. it has a dynamic structure. This means, that in a neutral or weakly acidic aqueous medium the borate bonds are broken first, and again a two-dimensional water-soluble form is formed. This enables easy and complete removal in the aqueous rinsing bath causes.

The exposure, development and rinsing of the multilayer material can be carried out in a generally known device

The three processing stages can be carried out in a compact and automatically operating unit which enables at least two and even all treatments for carrying out the method according to the invention. The multilayer photographic material can be supplied in sheet form or as a roll. After imagewise exposure, it is wetted with an aqueous alkaline processing liquid to carry out diffusion transfer imaging. This wetting can take place in any form, for example by dipping, spraying, spreading a viscous alkaline paste, using an applicator roller, etc. Suitable alkaline substances are alkali hydroxides, alkali carbonates, phosphates and borates. Especially since the alkali borates are very suitable because they release borate ions at the same time. The treatment of the multilayer material with the alkaline processing liquid takes place in the presence of the compounds necessary for carrying out the diffusion transfer image formation, namely at least one developer substance, a grain. plexing agent for silver halide and at least one substance for converting the diffusing, complexed silver halide into a visible image. The latter substances are provided in and / or on the image receiving layer below the silver halide emulsion layer. They are generally called development nuclei or nuclei for short. Both chemical and physical development nuclei, both of which are generally known, are suitable for the process according to the invention undeveloped silver halide is preferably added to the alkaline processing liquid.

However, it can also, at least partially, be incorporated into the image-receiving layer or a layer of the multilayer material other than the silver halide emulsion layer. The developing agents of the alkaline processing liquid may be added, but t according to a preferred embodiment, at least one

909840/1406

ORIGINAL INSPECTED

Part and even all of the developer substance is stored in at least one layer of the multilayer material, whereby the processing liquid becomes a mere alkaline liquid which is substantially free of Developer substances, and therefore more durable. A combination of hydroquinone and a 3-pyrazolidinone developer is preferably used ai. All types of developer germs, complexing agents for silver halide and well-known developing agents for the silver complex diffusion transfer process used in carrying out the method according to the invention will. These compounds can be incorporated in the usual concentrations, so that any further information is unnecessary in this context. ^

The final treatment of the multilayer material with an aqueous rinsing liquid to remove the photosensitive emulsion layer can be carried out in any desired manner. The aqueous liquid can be sprayed onto the multilayer material, but preferably the latter is passed through the aqueous bath. It is not necessary to use warm water because water at room temperature and even at a lower temperature is suitable for carrying out the processing step. The rinsing liquid is neutral and preferably _;

slightly sour. Depending on their nature, the emulsion layer dissolves like or does it go in the form of flakes or as a membrane, such as' already explained above. There is a very easy and complete removal of the emulsion layer.

The multilayer material for use according to the invention contains, in the order given, a support, an image-receiving layer and a light-sensitive silver halide emulsion layer. According to a preferred embodiment, between the image receiving layer and an adhesive layer as described above on the emulsion layer before.

The support can be made of paper or a transparent hydrophobic synthetic film such as a • Cellulose esters, e.g. cellulose triacetate, polyester or biaxially stretched polyethylene terephthalate.

The image-receiving layer is preferably a conventional hydrophilic colloid layer _r example, the de-V7icklungskeime contains a Gelatinaschicht, or transmits. The image-receiving layer is usually hardened, for example with a conventional hardener such as formaldehyde or glyoxal, or with a latent hardener which only exerts its effect in an alkaline medium, in this case during development. The latent hardener can be a hydrophilic colloidal binder such as the alginic and prorrylene glycol esters which form part of the binder of the image receiving layer. See British Patent 962,483 for more details.

To increase the flexibility of the image receiving layer often a latex, e.g. a polyethyl acrylate latex incorporated, preferably in an amount between 10 and 100% by weight in relation to the hydrophilic colloid Binder of the image receiving layer.

The final copy can be written on by incorporating a matting agent into the Considerably improve the image receiving layer. Pein distributed inorganic pigment particles, for example barium sulfate, Kaolin or silica particles are particularly suitable for this purpose. The pigment particles are preferred in an amount between 0.5 and 3.0 g per m2 applied to the image receiving layer.

The photosensitive layer can be any silver halide emulsion layer under the condition that their exposed silver salt during the diffusion, transfer process developed sufficiently quickly and their unexposed silver salt complexed sufficiently quickly

will. The silver halide emulsion layer can be highly sensitive in order to be able to make exposures in a camera. The emulsion layer can be low-sensitive, if it is to be exposed in contact. It may have a hard gradation with a view to reproducing Line work or a soft gradation if the reproduction of halftone originals is intended.

There may be provided one or more further layers, for example an adhesive layer between the emulsion layer and the image receiving layer as described above in detail, has a suitable adhesive layer between said image receiving layer and the support, a protective layer, which optionally anti-static properties, to the m emulsion layer, and one or more layers on the back of the material. An outer hydrophilic colloid layer on the back of the material can also contain finely divided pigment particles in order to improve the writability of this back. The preferred concentration of these pigment particles falls within the same limits given above for the use of pigment particles in the image-receiving layer. It goes without saying that the total concentration of these pigment particles should not be too high if the intention is to produce transparent copies.

All sorts of ingredients can be used in at least one of the ™

Layers of the multilayer material are present, e.g. developer substances, Complexing agents for silver halide and borating compounds as already indicated above. Other ingredients are preservatives for Entuicklersub "punch, Stabilizers, image tone influencers, sludge protection agents, anti-yellowing agents, hardeners, latent hardeners, plasticizers, latices and pigments.
