IPC: B29C48/21
Filed: 1973-02-22
Abstract: 1417765 Coating method EASTMAN KODAK CO 22 Feb 1973 [24 Feb 1972] 8731/ 73 Heading B2E [Also in Division D1] A method of coating a moving support with a layer of viscous non-aqueous coating composition having a viscosity greater than 30 cP comprises forming a composite layer containing a distinct layer of a viscous coating composition and immediately thereunder, a distinct layer of a less viscous non-aqueous liquid of viscosity less than 20 cP and allowing the composite layer to flow down a slide under the influence of gravity and transfer to the support so the less viscous liquid is in contact therewith. In the drawing a continuous web 1 is moved along the coating path by the roller 2, a slide hopper 3 having cavities 4, 4 1  and 4 2  into which liquid coating compositions are pumped. The compositions S and S 1  are liquid, non-aqueous coating compositions such as magnet coating compositions which are thixotropic, non-Newtonian dispersions comprising finely divided magnetic particles and a polymeric binder in a volatile solvent. The coating composition S 2  is of lower viscosity and can exhibit Newtonian flow characteristics. The compositions flow as layers through respective narrow elongated slots 6, 6 1  and 6 2  to form a composite layer made of three individual layers where the slots share an outlet 7 from the hopper at a level at the upper end of a slide 8. The composite layer flows by gravity down the slide surface 8 and is transferred to the web. As well as a continuous web the substrate may be a succession of individual supports conveyed on a conveyor belt. The highly viscous, non- aqueous coating composition may be of the type used in forming such layer as imageformed diazo diazonium salt-containing layers, vesicular layers, silica-, titania- or carbon-containing layers and phosphor layers of the type used in intensifying screens for radiography. Highly viscous suspensions or dispersions of ferro-electric materials such as barium titanate may also be used. The highly viscous layer may also be applied as a very thin layer such as less than 1 micron. It may comprise a dispersion or solution of a polymeric material such as vinylidene chloride/acrylonitrile copolymers, vinyl acetate/vinyl chloride copolymers, partially hydrolyzed and optionally cross-linked with isocyanate, and polyvinyl butyral. Suitable solvents are methyl ethyl ketone, methyl isobutyl ketone, ethyl acetate, cyclohexanone, acetone, methyl alcohol, benzene, dimethyl formamide and carbon tetrachloride. The lubricating layers may contain the same polymers and solvents as the more viscous layers. Suitable supports are discs, belts, paper or film tapes and suitable materials for cellulose nitrate film, cellulose acetate film, polyvinyl acetal film, polystyrene film, polyester film such as polyethylene terephthalate, which may be biaxially or asymetrically, stretched polycarbonate film, paper and metal such as aluminium and brass.
