Method for applying ultraviolet curable coating material and method for producing ultraviolet cured film

A method for producing an ultraviolet cured film, the method comprising the steps of:

• supplying an ultraviolet curable coating material containing an ultraviolet curable acrylic monomer into a mixer under a condition of greater than or equal to 8 MPa without diluting the ultraviolet curable coating material with an organic solvent;
• supplying carbon dioxide with a critical pressure or more into the mixer;
• mixing the ultraviolet curable coating material and the carbon dioxide supplied into the mixer to form a mixed fluid;
• spraying the mixed fluid under a condition of a critical pressure or more of the carbon dioxide to form a coating film;
• and
• irradiating the coating film with ultraviolet rays to form an ultraviolet cured film,
• wherein the ultraviolet curable coating material does not contain an organic solvent.

A method for producing an ultraviolet cured film on a plastic film, the method comprising the steps of:

• supplying an ultraviolet curable coating material containing an ultraviolet curable acrylic monomer into a mixer under a condition of greater than or equal to 8 MPa without diluting the ultraviolet curable coating material with an organic solvent;
• supplying carbon dioxide with a critical pressure or more into the mixer;
• mixing the ultraviolet curable coating material and the carbon dioxide supplied into the mixer to form a mixed fluid;
• spraying the mixed fluid on a plastic film serving as a workpiece to be coated under a condition of a critical pressure or more of the carbon dioxide to form a coating film;
• and
• irradiating the coating film with ultraviolet rays to form an ultraviolet cured film,
• the ultraviolet curable coating material does not contain an organic solvent.
