  • Patent number: 10286702
    Abstract: An electronic circuit board includes an ink receiving layer formed from a resin composition containing a polyvinyl acetal resin as a main component, and an electronic circuit formed in a pattern from an electrically conductive ink. An electronic circuit board production method includes the steps of: applying a liquid resin composition containing a polyvinyl acetal resin as a main component to form a layer of the liquid resin composition; heat-drying the liquid resin composition to form an ink receiving layer; and forming an electronic circuit in a predetermined circuit pattern from an electrically conductive ink by a printing method or a transferring method.

  • Publication number: 20170295651
    Abstract: An electronic circuit board manufacturing method according to the present disclosure is a method of manufacturing an electronic circuit board including a substrate and an electronic circuit having a predetermined pattern, the electronic circuit being fixed on the substrate and being made from a nanoink composition containing metal particles. The method includes the steps of: causing a printing plate to hold a nanoink composition containing metal particles, the printing plate including an ink holding part formed on a surface thereof and having a predetermined pattern; bringing a surface of the substrate into intimate contact with the printing plate to transfer the nanoink composition held on the ink holding part onto the substrate; and drying the transferred nanoink composition in an environment of 40° C. or below in the atmosphere to fix the nanoink composition after the transfer step, thereby forming an electronic circuit having a predetermined pattern.

  • Patent number: 7243601
    Abstract: A printing plate includes, on the printing surface of a raised part, grooves passing through from one side to another thereof. Preferably, the grooves are parallel to each other and equally spaced apart. More preferably the raised part is in the shape of a nearly-rectangular frame, and the grooves are provided such that one side of the near-rectangle and the longitudinal direction of the grooves form an angle of 45°.
