  • Publication number: 20100155987
    Abstract: The present invention relates to a method for casting an acryl film, which includes the steps of injecting a material of the acryl film into a space that is formed from a pair of substrates and a gasket positioned between a pair of substrates, and curing the material of the acryl film. The shrinkage ratio of the gasket is not less than 10% after the acryl film is subjected to the curing step, or the shrinkage ratio of the gasket after the acryl film is subjected to the curing step is the same as or larger than the shrinkage ratio of the material of the acryl film.

  • Publication number: 20100089262
    Abstract: A method of printing fine patterns prints a fine pattern on a substrate using an elastic mold with an intaglio pattern. This method includes applying a fine pattern printing ink to a surface of a patterned elastic mold; removing the ink applied to an embossed portion of the elastic mold by closely adhering an ink removing unit having a polymer resin or an organic compound with a surface energy from <a surface energy of the ink?2 erg/cm2> to <the surface energy of the ink+erg/cm> to the surface of the elastic mold and then detaching the ink removing unit therefrom; and closely adhering the elastic mold to a substrate to transcribe the printing ink thereto. This method allows forming a fine pattern with good quality since the ink applied to the embossed portion of the elastic mold may be effectively removed during a gravure process.

  • Publication number: 20100028540
    Abstract: A method for forming a black matrix includes (S1) applying a black matrix-forming ink to an intaglio-patterned elastic mold; (S2) removing an ink applied to an embossed portion of the elastic mold; (S3) transcribing the ink remaining in an intagliated portion of the elastic mold to a substrate; and (S4) curing and drying the ink transcribed to the substrate. The step (S2) may be performed in a way of closely adhering a surface of an ink removing unit having a surface energy from <a surface energy of the ink?2 erg/cm2> to <the surface energy of the ink+8 erg/cm2> to the embossed portion of the elastic mold and then taking away the ink removing unit from the embossed portion. This method allows forming a black matrix in a simple and economic way by applying the gravure process.

  • Patent number: 7514498
    Abstract: Disclosed is a coating composition that can provide structural materials having hydrophilicity, excellent self-cleaning property and long service life. The present invention also discloses a method for preparing the composition, a substrate, such as a film or structural exterior material like vinyl sidings, with the applied coating composition, and a method to prepare a substrate with the coating composition. The coating composition has hydroxy group-containing inorganic particles that improve the initial hydrophilicity of conventional coating agents. Additionally, by using two types of inorganic particles having different particles diameters, the coating composition can form a hydrophilic coating layer having a contact angle with water of 30° or less.
