Provided is a mesh structure of one embodiment of the present invention that reinforces the connection portions of mesh and suppresses a deterioration in quality by using a plating film. This mesh structure comprises an insulation film formed on the upper surface of the mesh, and a plating film that is formed on the lower surface of the mesh and that fixes the intersections of fiber threads in the mesh. The mesh structure is used for various applications such as a printing stencil. The insulation film functions as a masking film when forming the plating film.
[Problem] To provide a structure which includes a thin primer film that has been formed by a dry process and that tenaciously combines with a fluorinated silane coupling agent. [Solution] This structure according to an embodiment of the present invention comprises a base and a thin primer film formed on the surface of the base by a dry process, the thin primer film comprising at least one substance selected from the group consisting of silicon, titanium, aluminum, aluminum oxide, and zirconium.
[Problem] To provide a primer composition which is composed of an amorphous carbon material and forms a primer layer that is firmly bonded with a fluorine-containing silane coupling agent. The primer composition of one embodiment of the present invention is composed of an amorphous carbon material that contains at least one element selected from among silicon, oxygen and nitrogen.

Provided is a method for fixedly forming a water-and-oil-repellent layer on an amorphous carbon film. This method comprises the step of preparing a substrate, the step of forming an amorphous carbon film layer that contains silicon and nitrogen directly or indirectly over at least a surface of the substrate, and the step of forming a water-and-oil-repellent fluorine-containing layer on the amorphous carbon film layer through a coupling agent which is capable of forming hydrogen bonds with the amorphous carbon film layer by means of polarity and/or forming -O-M bonds (where M is any element selected from the group consisting of Si, Ti, Al, and Zr) with functional groups of the amorphous carbon film through a condensation reaction.
Disclosed is a screen-printing stencil provided with an amorphous carbon films such as a DLC film and a water-repellent/oil-repellent layer fixed tightly to at least part of said amorphous carbon film. The disclosed screen stencil (10) is provided with: a mesh (16) affixed to a frame (12); an emulsion layer (14), filled into in the mesh (16), in which a printing-pattern opening (18) is formed; an amorphous carbon film layer that contains at least one element among silicon, oxygen, and nitrogen, and is formed on at least part of the surface of the inner wall (22) of the printing-pattern opening (18); and a silane-coupling-agent thin-film layer (20) that contains fluorine and is provided on at least part of the amorphous carbon film layer.
Disclosed are: an amorphous carbon film whereby a layer comprising a material capable of condensation-reacting with hydroxy groups on the surface of the amorphous carbon film in a layer comprising the amorphous carbon film and arranged on a base material can be fixed onto the layer comprising the amorphous carbon film, and the fixation can be retained at a satisfactory level and in an equalized manner; and a method for fixing a layer comprising a material capable of condensation-reacting with hydroxy groups on the surface of an amorphous carbon film in a layer comprising the amorphous carbon film and arranged on a base material onto the surface of the layer comprising the base material. Si and O are added to the layer comprising the amorphous carbon film to improve the adhesion durability and the binding uniformity of the layer comprising the material capable of condensation-reacting with the hydroxy groups. Particularly, when a fluorine-containing silane coupling agent is used, it becomes possible to impart high functionalities including water-repellent/oil-repellent properties, abrasion resistance, chemical resistance, low friction and non-adhesiveness.
Disclosed is a multilayer film lamination method, by which an amorphous carbon film can be formed at the top of an aluminum or aluminum alloy base with high adhesion and corrosion of a layer below the amorphous carbon film can be suppressed. Specifically, a multilayer film structure with an adequate gradient of hardness can be obtained by forming a zinc substituted film on the surface of a base that is composed of aluminum or an aluminum alloy, forming a nickel plating layer by an electroless plating method using the zinc substituted film as a primer layer, then forming a hard chromium plating layer, and additionally forming, as the uppermost layer, an amorphous carbon film preferably at a temperature of 350˚C or less and preferably by a low-temperature plasma CVD method.
