Definitions
- This invention relates to photographic film elements. More particularly it relates to transparent photographic film elements which have a polyvinyl acetal color formersilver halide dispersion anchored to the support by means of a substratum composed of a copolymer of vinylidene chloride, an acrylic ester and itaconic acid. Still more particularly it relates to such elements wherein the film base is composed of an oriented highly polymeric linear ester of a dicarboxylic acid and a dihydric alcohol. The invention also relates to a method of preparing such elements.
- An object of this invention is to provide photographic film elements wherein a polyvinyl acetal color formersilver halide dispersion is firmly anchored to a film base.
- Another object is to provide such elements which have improved dimensional stability.
- 'A further object is to provide such elements wherein the film base is composed of an oriented highly polymeric ester of a dicarboxylic acid and a dihydric alcohol. Still other objects will be apparent from the following description of the invention.
- polyvinyl acetal color formers which are hydrophilic to water-soluble in character, as the binding agent for silver halide grains has been disclosed in a number of patents in the past six years. It has been difficult, however, to obtain adequate anchorage between thin layers composed of such dispersions and the usual types of hydrophobic film base. This is particularly true of film base composed of highly polymeric esters of dicarboxylic acids and dihydric alcohols and especially films composed of polyethylene terephthalates. These polyvinyl acetal dispersions do not have good adherence to the conventional gelatin sublayers which have been used for many years in anchoring colloid silver halide emulsion layers to hydrophobic films.
- the polyvinyl acetal silver halide dispersion layer has been applied, or (2) by first applying to the layer of copolymer a'thin layer of a hydroxyl polymer which contains a plurality of recurring intralinear groups as polymer-forming units, said polymers being water-soluble to hydrophilic in character.
- the adherence of the latter intermediate substratum can also be improved by heatingthe coated film base to a temperature of at least 70 C. before applying the silver halide dispersion. This heating step, however, can be applied after thepolyvinyl acetal color-.former-silver halide dispersion has been coated onto the layer of hydroxyl polymer.
- Synthetic hydroxyl polymers of the water-soluble and hydrophilictype include polyvinyl alcohol and its partially substituted water-soluble lower fatty acidesters, lower alkyl esters, and lower acetals.
- Polyvinyl alcohol is a tough, white, amorphous material. water. The more highly polymerized varieties are soluble in hot water and the medium or lower polymers aresol uble in cold water. They are usuallyprepared by hydrolysis of polyvinyl esters, such as polyvinyl acetate,
- the solutions used to coat the substratum of the synthetic hydroxyl polymer, free from color former nuclei may contain a coagulating agent, e. g., boric acid or a boric acid ester of a polyhydric alcohol, e. g., an ester prepared by reacting an alcohol. such as ethylene glycol, diethylene glycol, triethylene glycol, erythritol, sorbitol, mannitol, etc., with boric acid or a mixture of boric acid and borax, by heating the admixture to C. to C'. A copious evolution of Water occurs.
- the resulting products are viscous syrups or resins of a colloidal nature and have a high molecular weight and complex structure.
- boriborates They are readily soluble in Water but are substantially insoluble in hydrocarbons but probably hydrolyze to the boric acid and glycol in water. Their preparation is described in United States Patents 1,953,741, 2,223,349, 2,223,948, 2,223,949, and 2,224,011. These compounds have been referred to as boriborates:
- a hydrophobic film which may be composed of a cellulose carboxylic acid ester, e. g., cellulose acetate, cellulose acetate proprionate, cellulose acetate butyrate, cellulose nitrate, cellulose propionate; a superpolymer, e. g., a superpolyamide (nylon), an orientable highly polymeric linear ester of a dicarboxylic acid and a dihydric alcohol, e. g., polyethylene terephthalate, polyvinyl chloride, etc., is coated with a copolymer of vinylidene chloride, an acrylic ester and itaconic acid either from an organic solvent solution or from an aqueous dispersion.
- a cellulose carboxylic acid ester e. g., cellulose acetate, cellulose acetate proprionate, cellulose acetate butyrate, cellulose nitrate, cellulose propionate
- a superpolymer e. g
- the solvent should have only a mild solvent actiononthe base so that it will not appreciably dissolve the film base but have a superficial effect and merely soften or bite into the surface of the base.
- the substrata composed of a vinyl alcohol polymer and/or the polyvinyl acetal color former-silver halide dispersion coatings are formed by coating them onto the layer of vinylidene chloride copolymer.
- the useful ethylenically unsaturated esters which may be used in the copolymers are the alkyl esters of acrylic and methacrylic acids having from 1 to 18 carbon atoms in the alkyl group- (e. g., methyl methacrylate, ethyl methacrylate, butyl methacrylate, octyl methacrylate, n-dodecyl methacrylate, n-octadecyl methacrylate, methyl acrylate,
- the .copolymers of this invention .canbe :coated ,on ,the hydrophobic film base or support b,y any suitabletechs nique, e. g., coating from ahopper, skiml coating where the surface .of the film passes under arollerandcontacts with the surface of the liquid coatingnwith applicator or transfer rolls, spray coating, etc. Doctor blades, air doctor blades, etc., can be used to remove excess liquid.
- Example I A sample of polyethylene terephthalate filmbasehaving a thicknessof 0.003 inch, melting pointof above 200 C. and an intrinsic viscosity of 0.50 in a mixture of 2,4,6-trichlorophenol and phenol (70:100' parts by weight) was coated with an aqueous dispersion of the vinylidene chloride-methyl acrylate-itaconic acid copolymer described in Alles & SanerU. S. patent'application Ser. No. 151,274, filed March 22, 1950, now PatentNo. 2,627,088.
- the film was coated with a polyvinyl acetal color-former-silver halide dispersion, containing approximately 1.77% by weight of. silver iodobromide, composed of approximately 0.9% silver iodide and 99.1% silver bromide, dispersed in the polymeric colorformer (4.12% by weight of the total dispersion.) described in U. S. Patent 2,513,190.
- the silver halide dispersion was found to have good adherence to the film base.
- the film was exposed and processed as follows:
- Example II A second color film with a polyethylene terephthalate base of the kind described in Example I was treated as in said example except that the film was stretched biaxially after the vinylidene chloride-methyl.acrylate-itaconic acid copolymer layer had been applied and before the color former emulsion was applied. The resulting film was exposed and processed-as, described in Example I with similar results.
- Examplelll A sample of a polyethylene terephthalate film base of the type used in Example .I was treatedwith a copolymer of vinylidene chloride-methyl acrylate-itaconic acid of the type used in Example I, then stretched biaxlally and coated with a solution of.the.following composition:
- Example I After dryingatSO C., the ,film was heatedlat C. for 2 minutes and coated with a color-former dispersion of the type describedin Example I.
- the above polyvinyl acetal is described in Example. I'of Martin 2,513,189.
- Example V A sample of apolyethyleneterephthalatefilm base of the'type used in Example], was coated on'both-sides with a copolymer of vinylidene chloride of the :type used in Example I, stretchedbiaxially, and: was coated on one 'sidewith the twosubbing solutions asset forth in Example III. After drying," the film waszsubjectedto a temperatureof 100 C. for'severalminutes'and was then-coated-with the following-dispersionsand solutions, in the order listed.
- heating temperature of at least 70 C. has been referred to above the examples include higher temperatures and indeed temperatures up to 150 C. or more can be used if they do not deleteriously affect the coated layers. This can be determined visually with respect to the particular color former.
- temperatures up to 150 C. or more can be used if they do not deleteriously affect the coated layers. This can be determined visually with respect to the particular color former.
- the heating step may precede the application of the polyvinyl acetal color former layer.
- the invention is not limited to the use of the specific polyvinyl acetal color formers given in the examples as many other hydrophilic to water-soluble acetals of this general type can be substituted with similar results.
- suitable polyvinyl acetal color formers are those described in the following U. S. Patents: Jennings 2,397,864, Woodward 2,423,572, Mc- Queen 2,464,597, Corner & Woodward 2,465,067, Martin 2,472,910, Martin 2,538,257, Martin 2,476,988, Mc- Queen 2,477,462, Martin 2,489,655, McQueen 2,513,190, and Martin 2,518,704.
- color films for multicolor photography they will contain several superposed polyvinyl acetal color-former-silver halide emulsion layers which are so arranged and sensitized that they record different colors of the visible spectrum.
- These color formers can be selected to yield yellow, blue-green (cyan), and magenta, etc., quinoneimine, aszomethine,
- Filter dyes may be present in one or more of the above color former layers or in a separate stratum, e. g., a polyvinyl alcohol or equivalent hydroxyl polymer layer as described above.
- a yellow filter dye is used in a stratum above the two light-sensitive layers most distant from the camera side of the film.
- An advantage of the invention is that it provides a simple and effective process for improving the anchorage between a polyvinyl acetal color former layer and a hydrophobic film base. Another advantage is that the process can be carried out with conventional equipment. Still other advantages will be apparent from the above.
- the process which comprises coating a light-insensitive, water-permeable hydroxyl polymer layer onto a stratum composed of a tri-component copolymer made from 35 to 96% of vinylidene chloride, 3.5 to 64.5% of an ethylenically unsaturated ester and 0.5 to 25% of itaconic acid monomers, all percentages being by weight, said ester being taken from the group consisting of alkyl esters of acrylic and methacrylic acids having 1 to 18 carbon atoms in the alkyl group, acrylonitrile, methacrylonitrile and vinyl chloride; said stratum being on an oriented highly polymeric ester of a polymethylene glycol of 2 to 10 carbon atoms and terephthalic acid, said ester having a melting point from 200 C.
