Definitions
- This invention relates to removable antihalation layers for photographic film. More particularly this invention concerns a method of applying a certain type of antihalation layer to polyester film base.
- This invention has for one object to provide a method for applying various layers to film supports which exhibit inert or hydrophobic surfaces.
- a particular object is to provide a method for applying antihalation layers and the like to polyethylene terephthalate film products.
- .Still another object is to provide a method of the class indicated where the layer applied may be rendered substantially water insoluble but which is soluble in photographic developers.
- Still a further object is to provide a method which is relatively simple and economical. Other objects will appear hereinafter.
- aqueous solutions of polymers which polymers may have incorporated therein coloring materials or other materials for antihalation and antistatic effect, may be coated onto film supports having a hydrophobic or resistive surface.
- film support is exemplified by polyester film which may have had applied to the film during the manufacture thereof a latex layer before the film is oriented and crystallized.
- the coatings of the present invention pro- Patented Mar. 21, 1961 vide a removable backing which can give halation protection to photographic film comprised of polyester base.
- copolymers of methacrylic acid and methacrylate esters such as methyl, ethyl, propyl or butyl as alkali soluble carriers for fugitive dyes and/or colored pigments.
- 'Aqueous ammonia solutions of the various polymers referred to above may be coated to latex (methyl acrylate-vinylidene chloride-itaconic acid in a ratio of 15/83/02) coated biaxially oriented crystallized polyethylene terephthalate sheeting or other polyester sheeting.
- latex methyl acrylate-vinylidene chloride-itaconic acid in a ratio of 15/83/02
- the polymer, dye and/or pigment mixture adheres to the sheeting surface to a useful. degree.
- the coatings after drying exhibit excellent removability (alkali solubility) and .good moisture resistance.
- Fig. 1 is a diagrammatic across section on an enlarged scale of one embodiment of a polyester sheet which has a latex or aqueous emulsion polymer thereon.
- Fig. 2 is a diagrammatic cross section on an enlarged scale showing an embodiment in accordance with the present invention wherein a polymeric coating is applied which contains certain dyes.
- Fig. 3 is a flow sheet illustrating one embodiment of the process for coating polymeric sheeting with an antistatic layer in accordance with the present invention. Inasmuch as these figures may be readily understood from the legends thereon, further description appears to be unnecessary.
- Example I A mixture of: Percent 5 Butyl methacrylate-methacrylic acid polymer 1.75 Ammonium hydroxide (28% NH 0.30 Yellow dye of this composition, 4-[3-ethy1-2(3)- benzoxazolylidene)ethylidene] 3 methyl-l-(psulfophenyl) -5-pyrazolone 0.30 Magenta dye of this composition, 4-[(3-ethyl- 2(3) benzoxazolylidene)butenylidene] 3 methyl 1 p sulfophenyl 5 py-razolone 92.65 H O, in accordance with the present invention component of our coating composition.
- the coating had good adhesion.
- the backing is readily dissolved in photographic developers to give a clear film.
- the dyes are decolorized in the developer.
- our invention functions very satisfactorily for applying an antihalation layer over conventional latex treated polyester film.
- our coating and coating procedure of the present invention may be applied to other types of polyester films. These films may have surfaces which have been irradiated, pretreated with various chemicals or otherwise subjected to certain treatments prior to the application of our antihalation and antistatic layer thereover.
- a carbon of a particle size not exceeding about 18 m when applied to polyester sheets of the above type comprising latex coated oriented crystallized sheeting in a 1:1 carbon'vehicle ratio has a resistivity of the order of .01 10 ohms at an optical density of 0.2 at 550 m
- Carbon particles at a size of 43 m have substantially infinite resistivities at a density of 0.20. Accordingly, we prefer to employ a carbon having a particle size of not more than 30 III/.4.
- the aqueous coatings of the present invention may be applied by other types of apparatus such as extrusion or skim hoppers with air knife doctors.
- Our antistatic and anti-halation layers may be of any desired thickness or thinness. They may be of a thickness comparable to conventional coatings heretofore used. However, we prefer in general that our coatings while thin be of sufficient body to provide a continuous layer over the film base.
- the process of applying an antihalation layer to surfacesof polyester sheeting which sheeting in its manufacture has been coated with a latex, oriented and crystallized which comprises preparing a coating solution consisting of at least 90% of water and containing acrylateacrylic acid polymer having saturated lower alkyl groups, ammonium hydroxide, a coloring ingredient and a spreading agent, applying this aqueous coating solution to the surface of said polyester film which carries a latex coating upon which the antihalation layer is desired, and drying the coating sufficiently to volatilize oif substantially all of the water and the ammonium constituent.
- the 1 coloring ingredient includes at least one dye from the group consisting of a yellow dye, a magenta dye and a green dye.
- polymer is essentially comprised of butyl methacrylate and methacrylic acid.
- the latex coating contains at least two of the constituents from the group consisting of acrylonitrile, vinylidene chloride, acrylic acid, itaconic acid and butyl acrylate.
- the method of applying an antihalation coating onto photographic film base carrying a latex coating which comprises applying to the surface of the base upon which the antihalation coating is desired and upon said latex surface a solution containing at least 15% of water, a content of ammonia and the combination of ethyl cellulose phthalate containing ground-in carbon with methyl methacrylate methacrylic acid containing ground-in carbon and drying the coating thus applied sufliciently to volatilize oil substantially all of the water and ammonia components.
- a product comprised of a polyester sheet, said sheet having a latex coating thereon said latex coating carrying a layer of a material consisting of an acrylate-acrylic acid polymer having saturated lower alkyl groups, said polymer containing carbon particles of a size less than mn, said coating being characterized in that it is substantially water insoluble but soluble in photographic developer.
- a product comprised of a polyester sheet, said sheet having a latex coating thereon which latex is comprised of at least two constituents from the group consisting of acrylonitrile, vinylidene chloride, acrylic acid, itaconic acid and butyl acrylate, said latex coating having applied thereto a layer consisting of an acrylate-acrylic acid polymer containing at least one dye from the group consisting of yellow dye, magenta dye and green dye said coating being characterized in that it is substantially water insoluble but soluble in photographic developer.
