The present invention provides a bar coating method comprising the step of: weighing and applying a coating liquid by the bar with bringing the bar into contact with a continuously running web and supplying the coating liquid to an feed side of the web with respect to the bar to form a coating liquid puddle, wherein a plurality of coating liquids are supplied to the feed side of the web with respect to the bar via a plurality of slits formed in a multistage form in an feed direction of the web in order to apply the coating liquid having a high viscosity or low wettability without problems.

Bar coating method and apparatus

In the present invention, a coating liquid satisfies the liquid physical property conditions: (A) in the drying process, after the solid content concentration in the coating liquid is increased to 15% by mass or more by drying the coating film, or after the start of drying when the solid content concentration in the coating liquid is 15% by mass or more at the time of coating; (B) the shear viscosity of the coating liquid becomes 5 mPas or more for the shear rate of 10secor less; (C) the value obtained through dividing by the average viscosity the first differential coefficient, the increase coefficient of the increase rate of the shear viscosity relative to the increase rate of the solid content concentration is 0.15 or more; and (D) the second differential coefficient, an additional increase coefficient of the increase coefficient relative to the solid content concentration is positive.

Method for producing coated article

A peripheral surface of a coating rod has an area where grooves (convex portions) are formed. This area is ground by a grinding apparatus by which a maximum height Ry of the rod surface is adjusted to 15 &#x3bc;m or less. Further, a ratio of D/W is adjusted to 0.01 or more, wherein D is a total distance of the convex portions of the rod actually abutting on a web in an axial direction of the rod, and W is a coating width of the web. Furthermore, straightness of the rod is adjusted to 30 &#x3bc;m or less per 1 m, and roundness of the rod is adjusted to 10 &#x3bc;m or less. Micro-projections are removed by grinding so that scratches of a coating surface are prevented from occurring. Coating unevenness is prevented by improving the straightness and the roundness.

A coating apparatus for a traveling web comprising two coating heads and a traveling path changing roller is disclosed. A bar coater is arranged close to a pass roller. The bar coater is fixed at such a position as to contact the web when the pass roller is moved down. An extrusion coater is arranged below a backup roller in such a manner as to move up and down. If the pass roller moves up and bends up the traveling path of the web, the web separates from the bar coater. Then, if the extrusion coater moves up, the web is coated with the coating solution by the extrusion coater. If the pass roller and the extrusion coater move down, the web is coated with the coating solution by the bar coater.

A package of photosensitive planographic printing plates which comprises a stack of the photosensitive planographic printing plates between each of which a protection paper is interposed, wherein the coefficient of static friction between the surface of the photosensitive layer of the photosensitive planographic printing plate and the surface of the protection paper is 0.3 or more. In the package, slippage between the photosensitive planographic printing plate and the protection paper and abrasion of the photosensitive layer rarely occur through transport.

In a coating method using a coating rod, the coating rod is rotated in the reverse direction with respect to the running direction of the web, and the absolute value of V /V is set between 0.0001 and 0.06, where V (cm/sec) is a rotating speed of the rod and V (cm/sec) is a running speed of the web.

To provide a process for treating gas for decomposing organic solvent and/or other organic gas contained in exhaust gas effectively and simply at low costs to remove the decomposition product of organic gas by applying other process. The gas can be treated very effectively by decomposing or removing a target gas component dissolved in liquid capable of treating the gas, preferably, by applying microbial treatment, after bringing the gas rising into contact with the liquid falling in a gas treatment tower wherein part of the gas (branched gas ) is admixed with the liquid before feeding the liquid into the tower.

A slide bead coating method and apparatus which is able to form a stable bead over the width of coating solutions and regularly coat the coating solutions on a web to an edge region and which is able to change the width of the coating solutions without stopping the coating operation even if the width of the web changes. A discharged liquid from a nozzle is applied on both side edges of the coating solutions flowing down a slide surface. Thereby, the stable bead can be formed at the side edges of the coating solutions, so that the coating solutions can be coated on the web to the edge region. Edge bead is formed at both side edges of the coating solutions through the nozzle, so that the width of the coating solutions can be adjusted.

In a photosensitive lithographic plate including a photosensitive layer coated on the surface of a substrate and a mat layer formed on the photosensitive layer, plural resinous protrusions are provided on the back surface of the substrate in the form of a layer. Deterioration of vacuum adhesion due to the mat collapsed in a production process of a photosensitive lithographic plate including a step of winding is prevented, consequently, a photosensitive lithographic plate with uniform quality is obtained regardless of its wound position.

A presensitized plate which comprises a roughened and anodized aluminum plate having provided thereon a positive working light-sensitive composition layer which comprises a dye and can be made soluble in a developer upon exposure to light, wherein the dye concentration in the portion of the light-sensitive layer adjacent to or near the substrate is lower than that in the other portions of the light-sensitive layer. The presensitized plate according to the present invention has less color staining than PS plates of the prior art do and thus has excellent examining properties for plate-quality. The presensitized plate also has remarkable advantages of less stains around image-deleted areas during printing and high printing durability.
