ABSTRACT:
The present invention provides ultraviolet radiation (UV)-curable compositions and a method for making a UV-curable composition comprising: mixing at least one wax, at least one radiation-polymerizable compound, and at least one inhibitor of polymerization; dissolving the wax in the radiation-polymerizable compound by heating to provide a mixture of radiation-polymerizable compound, wax and inhibitor; cooling said mixture to provide a dispersion of the wax in the radiation-polymerizable compound; and micronizing the dispersion to provide a UV-curable composition. The invention further provides a method for coating a substrate with a UV-curable coating, and a coating, paint, varnish or ink comprising a UV-curable composition. Manufactured articles formed using the coatings, paints, varnishes and inks comprising a UV-curable composition are also provided.
