A method of producing an embossed sheet includes the steps of allowing a flexible strip-shaped sheet to continuously travel, forming a coating layer by coating the surface of the sheet with a radiation curable resin, transferring a pattern of concavities and convexities on the surface of the emboss roller to the coating layer by winding the sheet around the rotating emboss roller, curing the coating layer by irradiating the sheet which is wound around the roller with radiation, releasing the sheet from the emboss roller, laminating a protective film on one or both sides of the continuously traveling sheet after releasing, and taking up the continuously traveling sheet after lamination in the form of a roll. According to the method, a high quality, defect-free embossed sheet having a fine regular pattern of concavities and convexities on the surface can be produced at high line speed with high productivity.

This invention provides an indented sheet manufacturing method and apparatus which, by virtue of the use of CO2 gas as a gas accompanying a sheet-form body when the sheet-form body is caused to contact an indenting roller, can reduce the air-inclusion derived transfer defects of conventional techniques. Accordingly, even when the running speed of the sheet-form body is increased to improve productivity, the indented sheet having a regular pattern of fine indentations formed on a surface thereof can be manufactured with high-quality defect-free results. Further, according to the manufacturing method and apparatus of the present invention, the indented sheet having a regular pattern of fine indentations formed on a surface thereof can be manufactured with high-quality defect-free results at a high line speed and with good productivity.

An emulsification apparatus is used in a production apparatus of microcapsules. The emulsification apparatus is constituted with an outer cylinder and an inner cylinder coaxially arranged in a superposed manner, the outer cylinder is fixed, and the inner cylinder is rotated at a circumferential speed ω. A liquid being processed is fed into the gap between the outer cylinder and the inner cylinder, thus a shear force is exerted to the liquid being processed, and the liquid being processed is thereby emulsified. The relation between the magnitude d (mm) of the gap, the viscosity η (mPa·sec) of the liquid being processed and the circumferential speed ω (m/sec) of the inner cylinder is such that the circumferential speed co is controlled so that any one of the following relations may be satisfied: (1) When η≦20, d≦5/ω; (2) When 20

A method of fabricating a template (14) for a concave array mold (30) having a plurality of recesses of a high aspect ratio includes arranging a plurality of needles (10) in a mutually separated state and fixing the plurality of the arranged needles (10). This method allows a template for a concave array mold having a high aspect ratio structure to be easily and inexpensively fabricated. Further, the thus fabricated template can be used to easily and inexpensively fabricate a concave array mold. Furthermore, a needle array sheet can be fabricated by injecting and fixing a resin solution into the concave array mold (30) and separating the cured resin solution from the concave array mold (30).

The present invention provides a sheet-shaped object on which surface a regular, fine indented pattern is formed, without a decrease in accuracy of the formed pattern structure or defects caused by peeling faults. The present invention also provides a method of producing an indented sheet on which indents on an indented roller surface are transferred onto a surface of a sheet-shaped object. In order to solve the problems above, the method comprises the steps of: continuously running a band-shaped flexible sheet-shaped object; coating a radiation curable resin solution on a surface of the continuously running sheet-shaped object to form a coated layer; transferring indents on the indented roller surface onto the coated layer with the continuously running sheet-shaped object being wound onto the rotating indented roller; curing the coated layer by irradiating radiation with the continuously running sheet-shaped object being wound onto the indented roller; and peeling the continuously running sheet-shaped object from the indented roller, wherein the transferring step, curing step, and peeling step are carried out inside a casing, and temperature and humidity in the casing are each controlled to be within a certain variation range with respect to a target value.
