A plasma treatment method for surface treatment of a substrate with an atmospheric pressure plasma treatment apparatus is disclosed. The apparatus has a first electrode and a second electrode opposed to each other, a discharge space between the opposed electrodes, a voltage application means for applying voltage across the discharge space, a gas supply means for supplying a reactive gas and an inert gas to the discharge space. The method is one wherein the reactive gas at the discharge space is excited at atmospheric pressure or at approximately atmospheric pressure by applying voltage through the voltage application means to generate discharge plasma, and a substrate is exposed to the discharge plasma to be subjected to surface treatment, and wherein the reactive gas is not directly in contact with the discharge surface of the first electrode or the second electrode.

Plasma treatment method at atmospheric pressure

A coating apparatus for coating a conveyed support with an emulsion for a photographic light-sensitive material by letting the emulsion flow down between a pair of edge guides so as to form a curtain layer of the emulsion. The apparatus includes a slide surface, having a slit and inclined for a predetermined angle to the horizontal axis, for supplying the emulsion; side plates provided on both edges of the slide surface; the pair of edge guides each provided on respective one of the edges; and plural solution injecting outlets, each provided on respective one of the side plates, for supplying auxiliary solution; in which a coating operation of the conveyed support with the emulsion is conducted while the auxiliary solution is being flowed down along the edge guides at a flow rate between 0.3 cc/min. and 3.0 cc/min. from each of the solution injecting outlets.

Light-sensitive material and coating apparatus thereof

A method for producing a light-sensitive material. The method includes the steps of: discharging coating solution, including the light-sensitive material, from a coater die; forming a curtain layer of coating solution by causing the coating solution to fall from a die lip of the coater die in which the curtain layer is formed with an edge guide in which an end of the edge guide is arranged in the vicinity of the die lip and the other end of the edge guide is inclined toward the coater die in relation to the vertical line from the die lip; and coating a support with the coating solution by conveying the support at the downstream end of the curtain layer.

Method for coating a substrate using inclined edge guides

A method for producing light-sensitive material by using a curtain layer of coating solution. The method includes the steps of: discharging coating solution, including the light-sensitive material, from a coater die; forming a curtain layer of coating solution by causing the coating solution to fall from a die lip of the coater die in which the coating solution has at least 3 layers and a relational structure of dynamic surface tensions of the layers, satisfying the equation: .DELTA.K=.sigma.intermediate.sub.min -.sigma.outer.sub.max .gtoreq.0�mN/m! in which, .sigma.intermediated.sub.min �mN/m! represents the minimum value of dynamic surface tension of an intermediate layer among the layers, .sigma.outers.sub.max �mN/m! represents the maximum value of dynamic surface tension of an outer layer among the layers; and coating a continuous support with the coating solution.
