Patent number: 7172350Abstract: The present invention relates to a forming method using a thermal transfer printing sheet which is capable of implementing a three dimensional pattern. A method of forming a protruded surface using a thermal conduction difference of each portion of the pattern by a partial deposition thermal transfer printing sheet printed on a surface of a base material of a plastic substrate, or a gold or silver thin film partially printed by an engraving roller, and then the printed surface is heated to a certain temperature, so that the surface is divided into a heat blocked portion and a heat absorbed portion. In the forming method using a partial deposition thermal transfer printing sheet, or a gold or silver thermal transfer printing sheet, a thermal transfer printing sheet is dry-printed using only a heat and pressure, and a protruded surface is easily formed through a thermal diffusion process. It is possible to form various natural protruded surfaces.Type: GrantFiled: August 5, 2003Date of Patent: February 6, 2007Assignee: Korea Chemical Co., Ltd.Inventor: Sook Hee Chung

Patent number: 6939589Abstract: Disclosed is a thermal transfer paper comprising a metal layer and capable of partially dissolving the metal layer, which comprises a dissolving function formed of at least one resin selected from the group consisting emulsion resins, water-soluble acryl resins, water-soluble polybutyral resins, alcohol-soluble polybutyral resins, water-soluble vinyl resins and alcohol-soluble vinyl resins, water or an alcohol solvent, and sodium hydroxide or an acid on the metal layer. The thermal transfer paper according to the present invention is provided with a dissolving function layer 30 able to dissolve a part of a metal layer 20, preferably an aluminum deposition layer 21 to form a dissolved part according to a desired design or pattern. Therefore, it is possible to produce unique color and texture, unlike a metal layer pattern formed by oxidation of a part on the metal layer.Type: GrantFiled: February 21, 2003Date of Patent: September 6, 2005Assignee: Korea Chemical Co., Ltd.Inventor: Sook Hee Chung
