    摘要: A film is formed by casting a ribbon (1) on a support (3) from a flow cast die (2) while pulling said ribbon (3) toward said support (1) by providing a decompression area. The decompression area is divided into a middle portion, a left portion and a right portion. Degrees of decompression in these three portions satisfy the following formulae:0

    摘要: The invention pertains to a process for producing a surface-structured, sheet-like semifinished product made from a thermoplastic, having the following process steps: a thermoplastic plastic material is extruded in a molten state onto a temperature-adjustable moving belt or roller surface (5) that forms a negative structure (matrix) to the desired structure, the thermoplastic plastic material emerging from an outlet front (17) that is set transverse to the direction of motion and fully contacting the surface (5) to conform with the structure; the surface (5) is in sections subjected from without to a negative pressure which is at its maximum directly before the outlet front (in the running direction of the surface) so that the cavities belonging to the matrix (25) are practically void of air when the outlet front reaches them, and these cavities are completely filled with thermoplastic plastic material; the molten thermoplastic plastic material is while still resting on the surface - solidified by cooling, with the side brought into contact with the surface assuming the corresponding surface structure; once solidified, the semifinished product is removed from the surface.

    摘要: The present invention provides an improved solution casting method to manufacture, with high productivity, a polysulfone resin film superior in quality including appearance, surface smoothness, transparency and thickness accuracy. A polysulfone resin film is cast using the solution casting method wherein a solution of polysulfone resin by at least one solvent chosen from among anisole, dioxane or tetrahydropyrane is used as a resin solution for solution casting. To shorten the drying time even further, at least one solvent chosen from among acetone, methylethylketone, ethyl acetate, toluene and phenol can be mixed in the casting solution of polysulfone resin.
    The polysulfone film obtained by the present invention can produce a high-quality retardation film with superior optical properties.

    摘要: The present invention relates to an optical film production method for suppressing the remaining of air bubbles in microlenses, and in particular, an optical film production method comprising a step of rotating a roll die (51) having an outer circumferential surface having a plurality of concave-shaped microlens transfer portions disposed thereon and running a substrate (22) in the rotation direction; a step of supplying an active energy ray-curable composition ² onto a coating roll (53) disposed to be adjacent to the outer circumferential surface of the roll die, flattening the active energy ray-curable composition ² by a flattening means, coating the flattened active energy ray-curable composition ² on the outer circumferential surface of the roll die; a step of supplying an active energy ray-curable composition ± on the substrate and coating the active energy ray-curable composition ± on a surface of the substrate; a step of associating the compositions ± and ² at an association portion between the roll die and the substrate to form a liquid pool; and a step of irradiating a region between the outer circumferential surface of the roll die and the surface of the substrate with an active energy ray in a state in which the compositions ± and ² are sandwiched between the outer circumferential surface of the roll die and the surface of the substrate to cure the compositions ± and ².
