Definitions

  • R is a hydrogen atom or methyl group and R is an alkyl radical with (3) units of monomer having the formula:
  • R is a hydrogen atom or alkyl group
  • R and R are each divalent saturated aliphatic hydrocarbon radicals and R and R each represent hydrogen atoms or alkyl groups
  • said interpolymer comprises up to by Weight, of said (1), at least about 75%, by weight, of said (2) and up to about 10%, by weight, of said (3).
  • This invention relates to novel interpolymers of acrylic acid, unsaturated carboxylic acid esters and sulfobetaines. More particularly, this invention relates to the use of such interpolymers in photographic silver halide compositions. In a specific aspect, this invention relates to photographic elements which contain said novel interpolymers in at least one layer.
  • Gelatin is generally used in the preparation of photographic silver halide emulsions because of its good dispersing properties and its excellent protective colloid properties.
  • gelatin is susceptible to dimensional change when subjected to varying temperature or humidity and like conditions.
  • Various natural and synthetic materials have been proposed as substitutes for gelatin in one or more layers of a photographic element to provide dimensional stability.
  • many of these materials will salt-out, i.e., coagulate, in the presence of organic or inorganic salts which are often present in photographic silver halide compositions. It is evident, therefore, that a substitute for gelatin which combines improved dimensional stability with good salt tolerance will greatly enhance the art.
  • Another object of this invention is to provide novel and improved photographic compositions.
  • a further object of this invention is to provide novel interpolymers which can be used in photographic applications and which resist coagulation or salting out in the presence of inorganic or organic salts.
  • Another object of this invention is to provide novel polymer dispersions which are particularly useful in photographic applications.
  • a further object of this invention is to provide photo- Patented Nov. 19, 1968 "ice graphic elements comprising a photographic silver halide layer and, incorporated in at least one layer of said photographic element, interpolymers of acrylic acid, unsaturated car'boxylic acid esters and sulfobetaines.
  • a still further object of this invention is to provide photographic silver halide emulsions in which at least a part of the 'binding agent for the silver halide comprises a novel interpolymer as described herein.
  • film forming interpolymers of (1) up to about 15%, by weight, of acrylic acid, (2) at least about by weight, of a monomer having the formula:
  • R is hydrogen or methyl and R is an alkyl radical, desirably containing 1-12 carbon atoms ,with (3) up to about 10%, by weight, of a monomer having the formula:
  • R and R are each divalent saturated aliphatic hydrocarbon radicals, desirably containing up to 12 carbon atoms and R and R are each hydrogen or alkyl.
  • novel interpolymers of this invention are excellent substiutes for gelatin in photographic applications since they exhibit not only excellent salt tolerance in the form of latices or dispersions, but they also exhibit excellent dimensional stability, photographic inertness, water insolubility and water permeability. In addition, these copolymers exhibit good compatibility with gelatin which makes it possible to replace only a small part of the gelatin in a photographic composition, depending upon the particular combination of properties desired.
  • a significant feature of this invention is that the properties which make the novel polymers of this invention suitable gelatin substitutes are very closely related to the concentration and nature of the monomers from which the novel polymers are prepared. For example, a significant increase in acrylic acid content over that described herein gives a polymer which is soluble in water. This is undesirable in a gelatin substitute, particularly where it is to be used in unhardened photographic silver halide emulsions. Furthermore, a substantial increase in the sulfobetaine content of the interpolymer results in a product which shows little or no compatibility with gelatin.
  • the polymers described herein are prepared by interpolymerizing acrylic acid, an unsaturated carboxylic acid ester and a sulfobetaine.
  • the sulfobetaines employed in the preparation of these interpolymers include any of the sulfobetaines having the formula:

  • the R and R divalent saturated aliphatic hydrocarbon radicals can be branched or straight chain and will often contain up to 12 carbon atoms, as exemplified by methylene, ethylene, propylene, 1,2-propylene, tetramethylene, 1,3-isobutylene, pentamethylene, hexamethylene, octamethylene and the like.
  • the sulfobetaines include for example, 5,5, 10 trimethyl 9 oxo 8 oxa 5 azonia undecene- 1 sulfonate, 4 t butyl 9 methyl 8 oxo 7 oxa 4- aza-9-decene-l-sulfonic acid, 4,4,9-trimethyl-8-oxo-7-oxa- 4-azonia-9-decene-l sulfonate and the like.
  • the sulfobetaines can be prepared using any method known to be suitable for this purpose.
  • a convenient method for preparing the sulfobetaine monomers comprises reacting the appropriate amino alkyl ester of an unsaturated carboxylic acid with the appropriate sultone. Such a reaction can be carried out in the presence of an organic solvent such as acetonitrile, a liquid hydrocarbon or a ketone such as acetone at temperature up to about 100 C., preferably 50 to about 80 C. In general, the reaction is complete in less than 8 hours, often in about 2 to about 6 hours. The reaction is not pressure dependent and therefore superatmospheric or subatmospheric pressures can be employed.
  • the resulting sulfobetaine can be isolated by conventional procedures.
  • the reactants are generally employed in stoichiometric concentrations although slight excesses of either reactant can be employed.
  • specific reaction conditions for example, temperature, pressure, and the like, will depend upon the particular amino alkyl ester and sultone employed.

  • Such polymers are film forming and generally have an average molecular weight in the range of about 5000 to about 500,000 or more.
  • the temperature at which the interpolymers of this invention are prepared is subject to wide variation since this temperature depends upon such variable features as the specific monomers used, the duration of heating, pressure employed, and like considerations.
  • the polymerization temperature generally does"notexceed about 100 C., and most often, is in the rangeof about 50? to about 90 C.
  • suitable solvents or diluents for example, water or mixtures of water with water miscible solvents, as exemplified by methanol, ethanol, propanol, isopropyl alcohol, butyl alcohol, and the like.
  • the pressure employed in the polymerization is usually only suificient to maintain the reaction mixture in liquid form, although either su eratmospheric or subatmospheric pressures can be used.
  • concentration of polymerizable monomer in the polymerization mixture can be varied widely with concentrations up to about 40 percent, by weight, and preferably about 20 to about 40 percent, by weight, based on the weight of vehicle being satisfactory.
  • Suitable catalysts for the polymerization reaction include, for example, the free radical catalysts, such as hydrogen peroxide, cumene hydroperoxide, water soluble azo type initiators and the like. In redox polymerization systems the usual ingredients can be employed. If desired, the polymer can be isolated from the reaction vehicle by freezing, salting out, coagulation or by using other separation procedures suitable for this purpose.

  • a water soluble silver salt such as silver nitrate is admixed wtih a water soluble halide such as potassium bromide in the presence of the mixture.
  • the photographic silver halide is precipitated in an aqueous gelatin solution and digested in the conventional manner known to the art. After digestion, but prior to coating, there is added to the emulsion an aqueous dispersion of the interpolymer of this invention.
  • the bulk of the resulting dispersions can be increased by the addition of more of the interpolymer and/or natural or synthetic colloids or binding agents suitable for use in photographic silver halide emulsions.
  • Satisfactory colloids include, for example, gelatin, colloidal albumin, cellulose derivatives, synthetic resins such as polyvinyl compounds and the like.
  • the interpolymers of this invention can be employed in one or more layers of a photographic silver halide element.
  • the interpolymers described herein do not exhibit the very good peptizing action for silver halides shown by such binding agents as gelatin or other colloids.
