Abstract: An object of the invention is to provide an aluminum support for a planographic printing plate and a planographic printing plate precursor which can be used to obtain a plate precursor for a planographic printing plate that is excellent in terms of plate wear resistance in the case of being used to produce a planographic printing plate and exhibits excellent on-machine developability. In an aluminum support for a planographic printing plate of the embodiment of the invention, an average value of surface area-increase rates ?SSEM (%) is 200% or more, and an average value of pit depths ?hSEM (nm) is 400 nm or less.

Abstract: A coating method of forming a plurality of layers on a belt-like support continuously traveling, comprising: a step of applying a first coating liquid onto a front surface of the support to form a lower layer on the support; a drying step of removing a solvent in the lower layer until an amount of the residual solvent reaches not more than 100 mg/m2; a step of applying a second coating liquid onto the lower layer after drying to form an upper layer; and a drying step of removing moisture of the upper layer; wherein the drying step of removing moisture of the upper layer comprises: a first drying step of removing moisture in the upper layer until a moisture content of the upper layer reaches not more than 10% of moisture at the time of application within a range in which a following conditional expression (1) is satisfied: (1) temperature (Tw) of the support?average softening temperature (T0) of the lower layer+10° C.

Abstract: A coating device and a coating method are provided. The coating device comprises a coating station for coating a coating liquid on a band-shaped substrate running continuously, and a coat-adjusting station disposed downstream of the coating station for adjusting the coating liquid on the substrate so that the coating liquid layer is coated on the substrate at a predetermined thickness. The coating station and the coat-adjusting station comprise first and second bars for respectively coating and measuring the liquid agent. The coating liquid can be coated on evenly and in a stable manner even if the coating operation is performed with the substrate running at a high speed.

Abstract: A bar coating apparatus includes a coating bar for contacting an object to be coated, which object is conveyed in a constant direction, so as to apply a coating solution to and remove excess coating solution from the object to be coated, a weir member for forming a bead of the coating solution between the object to be coated and the coating bar, the weir member being disposed upstream of the coating bar in a direction in which the object to be coated is conveyed, a pressing member for pressing the object to be coated from a side thereof opposite from the coating bar, the pressing member being disposed near the coating bar; and a moving device for moving the pressing member in a thickness direction of the object to be coated.

Abstract: A coating device and a coating method capable of performing stable coating without causing defects such as a discontinuous coating film even if a web is run at a high speed. The coating device includes: a bar which is in contact with the web and can rotate about an axis; a liquid supply passage which is arranged adjacent to the bar at an upstream side from the bar and supplies a coating liquid to be applied to the web between the web and the bar to form a coating liquid reservoir when the web is being run; and an air-intrusion preventing unit which is arranged at an upstream side from the coating liquid reservoir and produces a liquid flow along a web surface to prevent an accompanying air film produced on the web surface from intruding into the coating reservoir when the web is being run.
