Patent number: 9988560Abstract: The invention relates to an antistatic silicone release film having a layer coated with an antistatic silicone release composition, and, used for semiconductors, electronics and display devices while addressing problems of static electricity generated when a general release film is separated from adhesive or an adhesive layer, and of contamination by such static electricity that causes critical product defects. The invention also relates to an antistatic silicon release film that can reduce product contamination caused by static electricity in peeling the film from adhesive or an adhesive layer, and achieves close adhesion between a substrate and a coated layer because of no interruption in curing a release layer, and also thereby has a stable release property.Type: GrantFiled: September 5, 2007Date of Patent: June 5, 2018Assignee: TORAY ADVANCED MATERIALS KOREA INC.Inventors: Jong-Uk Yoon, Jeong-Woo Lee, Moon-Bok Lee, Ki-Bong Suh, Sang-Pil Kim

Publication number: 20080166658Abstract: Disclosed herein is a polyester film for flexographic printing plates, which comprises: a polyester base layer (B); a detachable adhesive layer (A) formed on one surface of the polyester base layer using polyester resin and acrylic resin; and an antistatic layer (C) formed on the other surface of the polyester base layer. In the disclosed polyester film, the detachable adhesive layer is formed on one surface of the polyester base layer using polyester resin in combination with acrylic resin, and thus can have increased adhesion to the base layer and photosensitive resin. Also, the other surface of the polyester base layer has formed thereon the antistatic layer, which has excellent antistatic performance and, at the same time, is not transferred to a surface opposite thereto and is not greatly influenced by humidity. Thus, the disclosed polyester film is suitable for flexographic printing plates.Type: ApplicationFiled: May 8, 2007Publication date: July 10, 2008Applicant: Toray Saehan Inc., A corporation of The Republic of KoreaInventors: Sang Pil Kim, Ki Bong Suh, Chang Ik Hwang, Kyu Suk Lee

Patent number: 6984322Abstract: The present invention relates to a biaxially stretched, laminated, white microporous polyester film, which can be used in a wide range of industrial applications including printing, imaging, advertising and display. The film of the present invention comprises a porous polyester resin layer B containing a thermoplastic resin non-compatible with polyester; a polyester resin-based photic layer A formed on one surface of the resin layer B, the photic layer A having a 60-degree gloss of the surface thereof of more than 100%; and an aphotic layer C formed on the other surface of the resin layer B, the aphotic layer C having a 60-degree gloss of the surface thereof of less than 50%. The total density of the photic layer A and the aphotic layer C is 0.55–1.2 g/cm3. This film has excellent gloss and flexibility so that it is very suitable for use in printing and imaging.Type: GrantFiled: April 11, 2003Date of Patent: January 10, 2006Assignee: Toray Saehan, Inc.Inventors: Chang-Ho Suh, Ki-Bong Suh, Sang-Pil Kim

Patent number: 6822021Abstract: A release agent and a release liquid which are used for the manufacture of labels, double-sided tapes, etc., are disclosed. The release agent and the release liquid provide improved adhesion between a substrate and a release layer, and excellent peel strength betwveen the release layer and an adherent. The release agent includes a dispersion of a vinyl-modified colloidal silica, a dispersion of a platinum chelate catalyst, and a polysiloxane water-dispersible silicone emulsion. The release liquid is obtained by dispersing the release agent in water so as to have a solid content of 2.5˜30% by weight. The release film is produced by applying the release liquid on a substrate, followed by drying.Type: GrantFiled: December 16, 2002Date of Patent: November 23, 2004Assignees: Toray Saehan Incorporation, Haeun Chemtec Co., Ltd.Inventors: Sang Pil Kim, Ki Bong Suh, Moon Bok Lee, Jeong Woo Lee, Kwang Choon Chung, Myung Sun Gong, Chang Soo Kim

Publication number: 20040185281Abstract: The present invention relates to a biaxially stretched, colored polyester film, which can be widely applied in windowpanes of cars and buildings. This colored film comprises a transparent polyester layer A; a colored polyester layer B formed on one surface of the transparent polyester layer A, the colored polyester layer B containing dyes at the amount of 0.01-10% by weight; and a coating layer C rendered adhesive formed on the surface of the colored polyester layer B opposite to the transparent polyester layer A. When the colored film is adhered to the windowpanes of cars and buildings, it exhibits excellent ultraviolet blocking effect and flame retardance while protecting privacy. Also, even when glass is broken by impacts from the outside, the colored film can prevent a broken piece of glass from being scattered. Thus, the colored film is an improved polyester film having high functionality and multi-functionality.Type: ApplicationFiled: March 17, 2003Publication date: September 23, 2004Applicant: TORAY SAEHAN INC.Inventors: Chang-Ho Suh, Ki-Bong Suh, Sang-Pil Kim
