Patent number: 9615450Abstract: 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.Type: GrantFiled: November 15, 2013Date of Patent: April 4, 2017Assignee: LG CHEM, LTD.Inventors: Ji-Young Hwang, In-Seok Hwang, Dong-Wook Lee, Min-Choon Park, Seung-Heon Lee, Sang-Ki Chun, Yong-Koo Son, Beom-Mo Koo

Patent number: 9340058Abstract: 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.Type: GrantFiled: March 18, 2011Date of Patent: May 17, 2016Assignee: LG CHEM, LTD.Inventors: Houng-Sik Yoo, Beom-Mo Koo, Soon-Yeol Lee, Seung-Heon Lee, Jin-Young Park
