  • Patent number: 9828671
    Abstract: A method for fixation, onto a layer comprising an amorphous carbon film and provided on a base material, of a layer comprising a material condensation-reacting with hydroxyl groups on a surface of the amorphous carbon film, whereby, in the layer comprising an amorphous carbon film and provided on the base material, the amorphous carbon film can have a holding power which is strong enough to fix the layer comprising a material condensation-reacting with a hydroxyl group on the surface of the amorphous carbon film and can have uniformity of the holding power. Si and O are added into the layer comprising an amorphous carbon film to thereby improve adhesion durability and binding uniformity of the layer comprising a material condensation-reacting with a hydroxyl group.

  • Patent number: 9238350
    Abstract: One object is to provide a method for providing a water- and oil-repellent layer on an amorphous carbon film with excellent fixity. A method according to an embodiment of the present disclosure includes the steps of: preparing a substrate; providing, directly or indirectly on the substrate, an amorphous carbon film layer containing silicon and nitrogen in at least a surface thereof; and providing a water- and oil-repellent layer containing fluorine on the amorphous carbon film layer via a coupling agent capable of forming, with the amorphous carbon film layer, hydrogen bonds based on polarity and/or —O-M bonds (M is any one element selected from the group consisting of Si, Ti, Al, and Zr) by condensation reaction with functional groups of the amorphous carbon film.

  • Patent number: 9186879
    Abstract: [Object] To provide a screen printing stencil including an amorphous carbon film, such as a DLC film, and a water-oil-repellent layer provided on at least part of the amorphous carbon film so as to exhibit high fixability. [Solution] A screen printing plate 10 of an embodiment of the present invention includes a mesh 16 fixed to a frame body 12; an emulsion layer 14 which fills up the mesh 16 and has a print pattern opening 18; an amorphous carbon film formed on at least part of the surface of an inner wall 22 of the print pattern opening 18 and composed of at least one element of silicon, oxygen, and nitrogen; and a thin film 20 of a fluorine-containing silane coupling agent formed on at least part of the amorphous carbon film.
