    "1. A primer composition comprising an amorphous carbon material containing at least one element of silicon, oxygen, and nitrogen. 2. A structure comprising a substrate and an amorphous carbon film layer formed directly or indirectly on the substrate and containing at least one element of silicon, oxygen, and nitrogen. 3. The structure of claim 2 wherein the amorphous carbon film layer is subjected to a plasma process with any one of nitrogen, oxygen, and a mixture of nitrogen and oxygen. 4. The structure of claim 2 wherein the substrate is a mesh body used for a stencil printing plate. 5. The structure of claim 4 wherein the substrate is a mesh body used for screen printing. 6. The structure of claim 2 wherein the substrate is a porous sheet body. 7. A stencil printing plate comprising: a printing mesh body; an amorphous carbon film layer formed directly or indirectly on the printing mesh body and containing at least one element of silicon, oxygen, and nitrogen; and a water repellent layer or a water- and oil-repellent layer formed on the amorphous carbon film layer. 8. The stencil printing plate of claim 7 wherein the water repellent layer or the water- and oil-repellent layer is a thin film comprising a fluorine-containing coupling agent. 9. The stencil printing plate of claim 7 wherein the water repellent layer or the water- and oil-repellent layer is a thin film comprising a fluorine-containing silane coupling agent. 10. The stencil printing plate of claim 7 wherein the water repellent later or the water- and oil-repellent layer comprises: a first layer formed on the amorphous carbon film layer and composed mainly of a coupling agent capable of forming, with the amorphous carbon film layer, a hydrogen bonding and/or an - O-M bonding (M is any one element selected from a group consisting of Si, Ti, Al, and Zr) by condensation reaction; and a second layer formed on the first layer and composed mainly of a water repellent material or a water- and oil-repellent material. 11. The stencil printing plate of claim 10 wherein the coupling agent is a coupling agent selected from a group consisting of silane coupling agent, titanate-based coupling agent, aluminate-based coupling agent, and zirconate-based coupling agent. 12.

  "description_excerpt": "The present disclosure relates to a primer composition, and in particular, to a primer composition used as a primer layer for fluorine-containing silane coupling agent. Additionally, the present disclosure relates to a structure including a primer layer composed of the primer composition, and a method of producing the structure.\n\nThere are known surface modification processes in which coating is applied to a surface of a substrate with silane coupling agent containing fluorine to provide the surface of the substrate with oil repellence. For example, a fluorine coating layer composed of fluorine-containing silane coupling agent is formed on a surface of a screen printing mesh to provide the mesh with oil repellence and enhance demoldability of printing paste. In many cases, fluorine-containing silane coupling agent is not applied directly on a mesh body composed of a metal such as stainless steel but applied on a primer layer as an intermediate, so as to ensure the fixity of the agent on the mesh. For example, there are known methods in which a mesh is coated with a liquid primer and then fluorine-containing silane coupling agent is applied onto the liquid primer (See, Japanese Patent Application Publication Nos. 2006-347062 and 2009-45867).\n\nAdditionally, there are known techniques for electronic component conveyors, wherein a porous sheet provided on an adsorbing port of an adsorbing collet is coated with fluorine-containing silane coupling agent so as to prevent electronic components being conveyed from being adhered to the porous sheet.",
