The present invention refers in one embodiment to a method of manufacturing multilayer coated papers and paperboards, but excluding photographic papers and pressure sensitive copying papers, that are especially suitable for printing, packaging and labeling purposes, in which at least two curtain layers selected from aqueous emulsions or suspensions are formed into a composite, free-falling curtain and a continuous web of basepaper or baseboard is coated with the composite curtain, and paper or paperboard thereby obtainable.

A method for cutting a plate-like glass (G) by at least locally heating the plate-like glass (G) along a planned cutting line (5), whereby the entire plate-like glass (G) is cut by at least locally heating the plate-like glass (G) along the planned cutting line (5) while supporting members (2, 8) for supporting the plate-like glass (G) from the rear surface side on both ends at a site that is away from the planned cutting line (5) are arranged away from one another such that a space (S) is formed between the supporting members (2, 8) on the rear surface side of the planned cutting line (5).

Provided is an image forming method including providing a photothermographic material having image forming layers containing at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder on both surfaces of a support, imagewise exposing the photothermographic material with a fluorescent intensifying screen, and thermally developing the photothermographic material in a thermal developing apparatus having a heating section, wherein the heating section has at least two heating means and a difference between a sensitivity when the photothermographic material is developed at 25° C. and relative humidity of 75% and a sensitivity when the photothermographic material is developed at 25° C. and relative humidity of 20% is 0.20 or less. An image forming method similar to that described above in which the photothermographic material has an antistatic layer is also provided.

Image forming method using photothermographic material

The present invention refers to a method of producing a coated substrate comprising the steps of: a) forming a free flowing curtain, the curtain having at least one component capable of reacting, and b) contacting the curtain with a continuous web substrate.

Method of producing a coated substrate

The present invention refers to a method of producing a coated paper or paperboard, but excluding photographic papers, comprising the steps of: (a) forming a free flowing curtain comprising at least one layer, whereby the composition forming at least one layer of the free flowing curtain has a high shear viscosity of at least about 50 mPa.s, and (b) contacting the curtain with a continuous web substrate of basepaper and paperboard.

Process for making coated paper or paperboard

A method for reducing coating defects caused by strikethrough when simultaneously slide coating a first fluid layer, a second fluid layer, and a third fluid layer. The method includes preparing the first, second, and third fluids such that the first solute is incompatible with the second and third solutes and such that the first fluid minimizes strikethrough of at least one of the second and third fluids to a slide surface when the first fluid is positioned between the slide surface and the second and third fluids. The present invention is useful in preparing imaging, data storage, and other media.

Method for coating a plurality of fluid layers onto a substrate

The present invention provides an enclosure for a coating apparatus, the coating apparatus being of the type comprising a coater face adapted for the flow of a fluid thereover. The fluid flows over the coater face in the form of a film having one or more edges contacting the coating apparatus at one or more 'edge contact surface'. The enclosure (18) defines a partially enclosed space above one or more of the edge contact surfaces. The atmosphere within the partially enclosed space can be at least partially saturated with solvent vapor to prevent or inhibit drying of coating fluid at the edge contact surfaces. Also, the enclosure (18) has a shape that allows visibility of and access to a substantial portion of the coater face of the coating apparatus.

A method of microfinishing the edge of a die component (8) includes polishing the edges after the die component is machined by known methods to finish the edges of the die component to a smoother finish than the rest of the die component. This eliminates the incidence of undesirable streaking defects in the coating. The polishing step can be lapping, vapor honing, or grit blasting. The edges are polished to a finish of less than 8 microinches.

Coater die edge finishing method

A method for minimizing waste resulting from defects caused at the edges of a coating on a substrate which was applied to the substrate (18) by a slide coater (34). A first fluid (55) flows through the first slot (46) main portion at a first flow rate and through the first slot end portions at flow rates which differ from the first flow rate. A second fluid (60) flows through a second slot (48) onto a second slide surface (53) positioned relative to the first slide surface (53) and oriented such that the second coating fluid flows from the second slide surface onto the first coating fluid.

Method for minimizing waste when coating a fluid with a slide coater

A method for use with a slide coater (34) including preparing a first coating fluid (55) and flowing the first coating fluid down at least a first slide surface (53) of a slide coater when coating of the first coating fluid onto the substrate (18) is desired and flowing a minimizing fluid down the at least first slide surface when coating of the first coating fluid onto the substrate is not desired. The minimizing fluid has a composition which minimizes drying of the first coating fluid on the at least first slide surface. This invention applies to imaging, data storage, and other media.
