Definitions
- a preferred recording material for print-out reproduction contains silver behenate, 2-phenylindane-l,3-dione and traces of silver halide.
- the present invention more particularly relates to a photographic process in which the development of a latent image proceeds in dry state and with the aid of heat.
- hydroquinone methylhydroxy-naphthalene, methyl gallate, catechol, phenylene diamine, p-aminophenol, and I-phenyl-3- pyrazolidone were mentioned explicitly.
- the stability of said reducing agents is not as high as could be and therefore small amounts of acidic stabilizers are added that inhibit the oxidation and discolouration ofthe recording element under atmospheric conditions.
- a photographic recording material for the production of copies in a dry way which comprises a substantially light-insensitive silver salt as oxidizing agent, a reducing agent, and a lightsensitive heavy metal compound, which upon exposure photolytically forms metal nuclei that initiate a redox reaction upon heating, a compound of the indane-l ,3- dione series being used as reducing agent, which is capable of reducing the light-insensitive silver salt in a temperature range of 50 to l60C in the presence of the photolytically formed heavy metal nuclei.
- Reducing agents of the indane-dione-l,3 type that are suited for use according to the present invention correspond to the following general formula:
- an aromatic ring or ring system including a substituted aromatic ring or ring system, e.g., a benzene ring including a benzene ring substituted with alkyl, halogen e.g., chlorine and bromine, nitro, amino, substituted amino, alkoxy, cyano or aryl, and
- R represents hydrogen, an aryl group including a substituted aryl group e.g. phenyl, naphthyl, phenyl substituted with methoxy, dialkylamino, cyano, halogen, nitro, or azido (N;,).
- aryl group including a substituted aryl group e.g. phenyl, naphthyl, phenyl substituted with methoxy, dialkylamino, cyano, halogen, nitro, or azido (N;,).
- the indane-l,3-dione compounds can be prepared according to methods known to those skilled in the art.
- suitable oxidizing agents for the image-producing redox system are silver salts of organic acids that are insensitive or negligibly sensitive to light, e.g., silver saccharide, silver-5- chlorosalicylaldoxime, silver-5-nitrosalicylaldoxime or preferably a silver salt ofa long chain fatty acid with at most 30 carbon atoms, such as silver stearate, silver palmitate or silver behenate or the silver salts of aliphatic carboxylic acids with a thioether group as described in the US. Pat. Specification Nov 3,330,663.
- substantially light-insensitive it is not meant that the organic silver salt must be completely insensitive to light, but that it should at least be resistant to darkening under indoor illumination to an extent sufficient to prevent destruction or deterioration of copies during several days of storage under diffuse sun-light conditions.
- the preferred water-insoluble silver soaps of long chain fatty acids e.g., silver behenate and silver stearate are fairly stable to light, even in the presence of moisture.
- the soaps are conveniently prepared by precipitation with silver nitrate solution from aqueous solutions of the alkali metal soaps of corresponding fatty acids and with or without co-precipitation of the fatty acid in any desired proportion.
- the fatty acid content is restricted or omitted.
- Suitable light-sensitive salts of heavy metals forming metal nuclei upon exposure which are capable of initiating the image-producing redox reaction, are e.g., inorganic and organic salts of silver, mercury and gold.
- Heavy metals of the lb group of the periodic table of the elements such as silver salts and particularly silver halide are preferred.
- the light-sensitive heavy metal salt that is suited for a particular redox system can be determined by some tests. For instance the metal salt can be mixed in the form of an aqueous suspension with the components of the redox reaction. No modification should occur in the dark. If this mixture is then exposed to ultraviolet radiation it should change colour rather quickly. If these conditions are fulfilled, the heavy metal salt is suited for the redox system.
- the light-senstive heavy metal salt is used in relatively small amounts comprised between approximatively 0.05 and 0.2 percent by weight calculated on the weight of the oxidizing agent. Such amounts of lightsensitive salt suffice for most systems. In certain cases, however, these amounts may be lower or higher.
- the preferred photographic recording process according to the present invention comprises the steps of (l) forming silver nuclei in accordance with photographically exposed areas of a recording element containing:
- A a substantially light-insensitive silver salt of an organic acid
- a photosensitive silver halide capable of producing photolytic silver in an amount sufficient to catalyse the reduction by heating above room temperature of said substantially light-insensitive silver salt by means of an indane-l ,3-dione compound containing at least one hydrogen atom in the 2-position, and (2) heating the substantially light-insensitive silver salt in contact with said indane-l ,3-dione compound for a time and at a temperature sufficient to cause reduction of said silver salt and a visible colour change in the light-exposed areas.
- the light-sensitive silver halide should be present in such a low amount, that the photolytically formed heavy metal nuclei can initiate the redox reaction. Yet, the concentration of the silver halide should be so weak that no colour change of the copying material at all or but a negligible colour change is brought about by the metal nuclei formed.
- the silver halide can be added to the coating solution for the layer containing the components for the redox reaction or it can be formed in situ in the coating solution e.g., by precipitation. In the latter case the silver ions needed for this precipitation of silver halide can essentially originate from the light-insensitive silver salt.
- the halide ion (i.e., Cl, Br, I, or a mixture thereof) for the production of the photosensitive silver halide in situ can be supplied in different manners. ne convenient procedure involves briefly exposing the surface of the silver salt particles or coating to the vapours ofone or more halogen acids, the extent of the reaction being controlled by adjusting both the concentration of the vapour and the time of exposure.
- the method of applying the halide ion from a liquid medium is particularly useful in the preparation of light-sensitive heat-developable recording materials. It permits the simultaneous efficient application of the reducing agent and of spectral sensitizing dyes or other components e.g., toning agents, pigments, e.g., titanium dioxide, silica, phthalazinone, or photoconductive compounds, e.g., photoconductive zinc oxide.
- the dye employed in spectrally sensitizing or otherwise modifying the sheet may itself serve as the source of halide ion.
- the silver halide may alternatively be formed on the silver behenate or other organic silver salt prior to coating the latter on the paper or other carrier surface.
- the silver salt dispersed in a volatile non aqueous liquid medium, is treated with small amounts of HC], HBr or Hl prior to coating.
- the dry salt in finely divided particulate form may also, although less desirably, be treated with a source of Cl, Br, I" or a mixture thereof in the dry state to provide in situ formation of silver halide at the surface of the particles.
- Hydrogen chloride and hydrogen bromide are effective treating agents.
- Various water-soluble inorganic halides are somewhat more easily handled and are equally effective; ammonium bromide has been found particularly useful since the ammonium ion is subsequently readily removable, but halides of various metals, e.g., sodium, magnesium, cobalt and zinc, are also effective.
- lonisable organic halogen compounds are also useful, examples being triphenylmethyl chloride, triphenylmethyl bromide, 2-bromo-2-methylpropane, Z-bromobutyric acid, Z-bromoethanol, and benzophenone dichloride.
- the in situ formation of the silver chloride or bromide from an organic acid silver salt enhances the pho- 4 tosensitivity and imaging capability of the composition, more than added pre-formed silver halide.
- binding agents are organic polymers such as copolymers of vinyl chloride and vinyl acetate or of butadiene and styrene, polyethylene, polyamide, polyisobutylene, polyvinyl chloride, polyvinylidene chloride, polyvinyl pyrrolidone, polystyrene, chlorinated rubber, polyvinyl butyral, polymers of acrylic or methacrylic acid esters or copolymers of derivatives of acrylic acid and methacrylic acid, derivatives of cellulose such as cellulose nitrate, cellulose acetates, cellulose propionate or mixtures thereof, e.g., cellulose acetobutyrate.
- organic polymers such as copolymers of vinyl chloride and vinyl acetate or of butadiene and styrene, polyethylene, polyamide, polyisobutylene, polyvinyl chloride, polyvinylidene chloride, polyvinyl pyrrolidone, polystyrene, chlorin
- the light-sensitive layer may be a self-sustaining layer, but is preferably applied to an appropriate support.
- the support should be stable at the processing temperature comprised between 60 and 200C.
- Suitable supports are e.g., sheets or foils of paper, cellulose acetate, polyethylene terephthalate, textile, metals foils or glass.
- Paper supports may be provided with the usual auxiliary layers such as e.g., baryta layers and polyethylene layers.
- the concentration of the reducing agent and of the oxidizing agent in the layer may vary within wide limits.
- a recording material according to the present inven tion preferably comprises the organic substantially non-light-sensitive silver salt and an indane-dione-l,3 compound in a molar ratio of 1:1 to l:10.
- the weight proportions of the components of the redox reaction and the binding agent vary between 4:l and approximately 1:1.
- the thickness of the light-sensitive layer may be adapted to the requirements of the specific reproduction process. A layer thickness between 5 and [00 um appears to be sufficient in normal cases.
- the support has a thickness ranging between 0.1 and 0.8 mm.
- the light-sensitive layers may be sensitized optically by the addition of dyes.
- Suitable optical sensitizing agents for common silver halide emulsion layers are e.g., cyanine dyes, merocyanines, oxonols or rhodacyanines of different nature such as those described e.g., by F. M. Hammer in the The Cyanin Dyes and Related Compounds" 1964.
- the image-wise exposure can be preformed with the light sources normally used in photographic techniques, e.g., mercury lamps, iodine quartz lamps or incandescent bulbs.
- the nature of the light source to be used depends on the spectral sensitivity of the heavy metal salt used.
- the common incandescent bulbs can be used advantageously in the case of silver halides, wherein the exposure takes only a few seconds.
- the exposed material is heated uniformly to 60l60C.
- the time and temperature required for the heat treatment depends on the nature of the redox system. Generally a time varying between 3 and seconds is sufficient. Dark brown to black images are formed mostly. They can be used immediately.
- EXAMPLE Preparation of the non-light-senstive silver salt A mixture of equimolar parts of silver behenate and behenic acid is prepared by precipitation with silver nitrate from a solution of sodium behenate and behenic acid in alcohol and water. The precipitate is thoroughly washed and dried.
- a first coating composition containing the following ingredients was ball-milled for [2 hours mixture of silver behenate and behenic acid
- the coating composition was applied to a glassine paper support at a ratio of I00 g a 200 g per sq.m and dried at 30C.

- polyvinyl butyral (95 of acetal groups) l0 g 2-phenylindane-l,3-dione 8 g melting point: 150C prepared according to C.A. 49, 6856e.
- the thus prepared photosensitive sheet was exposed while in contact with a silver image transparency to a 40 W light exposure unit placed at a distance of 5 cm and used in the 3M dry-copying apparatus model M 179.
- the sheet was then developed at 95C and a speed of l meter per 20 seconds.
