Abstract: PURPOSE: A film coating device using micro gravure is provided to smoothly flow in a coating solution by forming specific grooves on the surface of a side wall, and to minimize the rubbing of the side wall and the surface of the gravure roll. CONSTITUTION: A film coating device using micro gravure includes: a liquid pan dipping a coating solution; and a gravure roll rotated by being dipped a part of the gravure roll in the liquid pan to transfer the coating solution to a film. Side walls having curved upper side corresponding to the surface of the gravure roll are installed at both sides inside the liquid pan so that a proper amount of the coating solution is dipped. Grooves(4) are formed on the curved surface of the upper end of the side wall.

Abstract: PURPOSE: An anti-reflection film and manufacturing method of the same are provided to reduce the number of coating defect acknowledged in the man eyes by minimizing the size of the ring spreading out and by reducing the size of the coating defect even if the hard coating liquid is spreaded on foreign material existing on base film, and to control generation of the coating defect itself or reduce the number of the coating defect by reducing sublimate which generates when photoinitiator absorbs the energy from the UV lamp. CONSTITUTION: The anti-reflection film is manufactured by filming the hardcoating layer(32) on the base film(10) for anti-reflection. The thickness of the hardcoating layer spreaded on the base film is 2.0 - 3.0μm. The photoinitiator content of the hard coating liquid used in the hardcoating layer coating is 1.0 - 2.5 weight%. The photoinitiator is a combination of one or more than one selected from the Acryl resin, urethane resin, melamine resin, organosilicate compound, silicone resin. The anti-reflection film spreads more high refractive layer(33) and low refractive layer(34). The hardcoating layer is formed with the gravure coating method. The gravure roll used in the hardcoating layer coating is 180 mesh and the gravure roll speed is 13 - 17mpm.
