The tip of a downstream lip is disposed so as to be further separated from a web as compared to the tip of an adjacent lip, and downstream and upstream spacers are placed so that the a liquid discharge port length interposed between two downstream spacers is shorter than that of a liquid discharge port interposed between two upstream spacers. The method includes coating coating-liquid to the surface of the web from a slot die, which is formed so that tips of the downstream spacers are placed at the same position as a tip of the adjacent lip or further protrude so as to be closer to the web than the tip of the adjacent lip; depressurizing the cover inside that is provided on the upstream side of the slot die during the coating; and drying the coating-liquid that is coated to the surface of the web.

The present invention provides a method for manufacturing an optical film which is superior in transportability and lamination suitability in a lamination step in a polarizing plate processing. A slide coating device includes applying one or more coating liquids flowing down on a slide face to the surface of a continuously traveling strip-shaped support through the bead of the coating liquids, which is formed by the coating liquids in a lip clearance formed between a lip tip in the lower end of the slide face and the surface of the support, and also having guide plates on both ends of the slide face, which guide the downflow of the coating liquids, wherein the guide plates are provided so that the lower ends of the guide plates are retracted from the lip tip by the range of more than 0 mm and less than 4 mm.

A multi-layer packaging laminate is produced by simultaneously applying at least two wet coating layers to a substrate web (10) in a slide coater or curtain coater having a slide block (14) over which laminar flow streams of coating liquid flow to reach the substrate web. At least one layer is less than 20 μm thick (wet) and at least one layer has oxygen barrier or scavenger properties.

Provided is a method of producing a multilayer coating film, the method including the steps of: turning multiple coating liquids into multiple layers in advance; and transferring the coating liquids turned into multiple layers onto a substrate, in which a mixing-preventing component that prevents two kinds of coating liquids which contact each other from mixing with each other is added to at least one of the two kinds of coating liquids in advance, and molecules of the mixing-preventing component are localized toward a vicinity of an interface between layers of the coating liquids so that the interface between layers is secured. The production method includes producing a multilayer coating film having good interlayer adhesiveness with ease and good productivity, by collectively applying multiple coating liquids without using a gelling agent or the like for modifying the viscosity of each coating liquid to be laminated.

Process for applying multi-layer extrusion coatings to substrate at low temperature is described, employing as one extrusion coating layer a defined polyethylene-containing component, and, as the second extrusion coating layer at least one second extrudable polymeric composition. Also provided are novel extrusion coated articles comprising substrate having coated thereon defined polyethylene-containing component and at least one other extrudable polymeric composition. These articles display good adhesion of extrusion coating material to the substrate without the degradation of the extrudable coatings caused by exposure to excessive levels of heat as is required for successful extrusion coating employing prior art materials.

Substrates are coated by a process which comprises co-extruding onto the substrate, e.g. aluminium foil, a layer of an olefin terpolymer and a layer of polypropylene, the olefin terpolymer being adjacent to the substrate and the polypropylene being adjacent to the olefin terpolymer. The olefin terpolymer is a terpolymer of an olefin, e.g. ethylene, an unsaturated carboxylic acid or anhydride, e.g. acrylic acid, and an unsaturated ester, e.g. methyl acrylate, in which the amount of carboxylic acid or anhydride groups in the terpolymer is at least 3 mole % and the amount of ester groups in the terpolymer is at least 3 mole %.

摘要:
A method is taught for preparing a coating hopper prior to initiation of coating a liquid coating composition at a predetermined coating flow rate onto a moving substrate wherein the coating hopper includes at least one internal flow path therethrough. The internal flow path(s) of the coating hopper are drained. The liquid coating composition is introduced into internal flow path(s) at a purge flow rate which may be determined empirically. The internal flow path(s) are filled with the liquid coating composition and with the liquid coating composition then discharging from the internal flow path(s) onto a slide surface of the coating hopper, the liquid coating composition flowing down the slide surface and over a lip of the coating hopper at the purge rate to a drain. The flow of the liquid coating composition through the internal flow path(s) is maintained at the purge rate until air within the internal flow path(s) has been displaced from the coating hopper. Preferably, the internal flow path(s) are flushed with water prior to draining.
