  • Patent number: 8785577
    Abstract: Acrylic fine particles formed by polymerization of a (meth)acrylate containing monomer with a cross-linking agent are disclosed. The cross-linking agent includes a first cross-linking agent having at least three (meth)acryloyloxy groups and at least one functional group —OH, —COOH, or a combination thereof, and the acrylic fine particles can have a coefficient of variation (C.V.) of about 20 to about 60%. The acrylic fine particles can have high heat resistance and solvent resistance and also enhanced compatibility with a binder and a solvent. Accordingly, the acrylic fine particles can exhibit remarkably increased dispersibility when used in a diffusing film or the like, and thus are suitable for use as a diffusing agent.

  • Patent number: 8189238
    Abstract: A method and system for managing facsimile (fax) data in an integrated manner. The system includes an integrated fax server, and a fax terminal configured to transmit and receive fax data via a first communication network and to transmit both the transmitted and received fax data to the integrated fax server via a second communication network. The integrated fax server stores fax data received from the fax terminal in a database. The fax terminal includes a fax machine connector configured to receive fax data from a fax machine, a first communication network connector configured to transmit and receive fax data via a first communication network, and a server interface unit configured to transmit fax data to the integrated fax server. Accordingly, the integrated fax server manages transmitted and received fax documents with increased efficiency and security. Thus, the difficulty of managing fax documents due to spacial restriction is diminished.
