  • Patent number: 9615450
    Abstract: The present invention provides a method for manufacturing a conductive pattern, comprising the steps of: a) forming a conductive film on a substrate; b) forming an etching resist pattern on the conductive film; and c) forming a conductive pattern having a smaller line width than a width of the etching resist pattern by over-etching the conductive film by using the etching resist pattern, and a conductive pattern manufactured by using the same. According to the exemplary embodiment of the present invention, it is possible to effectively and economically provide a conductive pattern having a ultrafine line width.

  • Patent number: 9524043
    Abstract: The present invention provides a method of manufacturing a touch screen, comprising the steps of: a) forming a conductive layer on a substrate; b) forming an etching resist pattern on the conductive layer; and c) forming a conductive pattern having a line width smaller than the line width of the etching resist pattern by over-etching the conductive layer by using the etching resist pattern and a touch screen manufactured by the method. According to the present invention, a touch screen comprising a conductive pattern having an ultrafine line width can be economically and efficiently provided.

  • Patent number: 9340058
    Abstract: The present invention relates to a blanket for offset printing and a manufacturing method thereof. The blanket for offset printing according to an exemplary embodiment of the present invention comprises a cushion layer, a support layer, and at least two surface printing layers, wherein the at least two surface printing layers comprise a silicon-based resin in which at least one of a hardness value, a fluorine group content value, and a silicon oil content value is different. The blanket for offset printing according to the exemplary embodiment of the present invention comprises the surface printing layer formed in at least two layers to prevent the surface printing layer from being swollen due to ink, thereby reducing a process waiting time and improving a process margin.
