    Abstract: The disclosure relates to the field of the protection of security documents, such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the present disclosure provides processes for producing optical effect layers (OELs) on a substrate and OELs obtained thereof, said process including two magnetic orientation steps: a step of exposing a coating composition having platelet-shaped magnetic or magnetisable pigment particles to a dynamic magnetic field of a first magnetic-field-generating device so as to bi-axially orient at least a part of the platelet-shaped magnetic or magnetisable pigment particles, and a step of exposing the coating composition to a static magnetic field of a second magnetic-field-generating device, thereby mono-axially re-orienting at least a part of the platelet-shaped magnetic or magnetisable pigment particles.

    Abstract: A tow prepreg manufacturing apparatus applies resin to an original tow of reinforcing fibers. The tow prepreg manufacturing apparatus includes an oiling roller, a scraper, a resin reservoir, a tube pump, and a controller. The oiling roller is supplied with resin while rotating at a predetermined rotation speed. The scraper adjusts the shape of the resin supplied onto the oiling roller. The resin reservoir supplies resin to the oiling roller. The tube pump discharges resin to the resin reservoir. The controller controls the tube pump so that the amount of resin held in the resin reservoir remains constant and controls the rotation speed of the oiling roller so that a resin content of a wound tow prepreg becomes equal to a target resin content.

    Abstract: In a second liquid supply step, a second liquid film and a first liquid film surrounding a side of the second liquid film are formed on an upper surface of a substrate. Then, in a vapor layer formation step, by heating the substrate, a second vapor layer is formed by evaporating the second liquid contacting the upper surface of the substrate, and the second liquid film is held on the second vapor layer. Since the second liquid included in the second liquid film has a high vapor pressure, a height position of a lower surface of the floating second liquid film may be kept high. By blowing a gas to the floating second liquid film, a hole is formed in the second liquid film, and by expanding the hole toward an outer periphery of the substrate, the first liquid and the second liquid are removed outside the substrate.

    Abstract: A method and a jig for forming a pattern, the method and the jig being capable of realizing various and unique pattern designs due to magnetic particles included in the magnetic ink being distributed in various densities according to intensity of the magnetic force. The method includes: preparing a jig which generating magnetic force, applying magnetic ink on a surface of a substrate to form a print layer, disposing the substrate configured with the print layer above the jig, forming a magnetic pattern on the print layer by applying magnetic force generated from the jig, and drying the print layer.
