Abstract
The present invention provides a highly reliable technology for manufacturing a substrate with protrusions. After filling an UV-curable transfer material into the grooves of an intaglio plate for transfer, the UV-curable transfer material is cured by irradiating UV rays under the conditions where it is exposed to an atmosphere that contains at least one of oxygen and ozone while a curing-inhibited portion is formed in an area of the UV-curable transfer material exposed to this atmosphere, and the UV-curable transfer material is transferred to the substrate to form the protrusions, while the curing-inhibited portion is made to adhere to the substrate.
Claims5
A material transfer method for transferring a transfer material filled in concave portions of an intaglio plate for transfer onto a substrate, comprising:
- preparing an UV-curable transfer material that is not cured in an atmosphere that contains at least one of oxygen and ozone, even if UV rays are irradiated, and that indicates adhesion in an uncured state;
- filling said transfer material into the concave portions of said intaglio plate for transfer, and irradiating the UV rays onto said transfer material in said atmosphere that contains one of oxygen and ozone to cure portions other than the portion exposed from said intaglio plate to the atmosphere;
- and
- adhering the uncured area of said transfer material to said substrate and transferring said transfer material to said substrate.
