Abstract:
PROBLEM TO BE SOLVED: To improve the conventional method by using (meth)acrylated polyester powders. SOLUTION: The problem is solved by a method of producing a heat resistant raised print on a substrate using a radiation-curable powder composition which is cured by using radiation. The powder composition includes one or more radiation-curable (meth)acrylated polyester powders, and, if required, one or more additives. In the method, a (meth)acrylated polyester powder composition is applied to a wet inked print on a substrate to form the coated print, the coated print is heated to a melting temperature to form a raised-melt, and irradiation is applied to the raised-melt so as to form the heat resistant raised print cured by the radiation on the substrate.

Abstract:
A method of forming heat-resistant raised print on a substrate using a radiation-curable powder composition where the composition is cured using radiation. The powde r composition includes one or more ultraviolet radiation curable (meth)acrylated polyester powders, and optionally one or more additives. The method includes applying the (meth)acrylated polyester powder composition to a wet inked print on a substrate to produce a coated print, heating the coated print to melt temperature to form a raised-melt, and irradiating the raised-melt to form the radiation-cured heat-resistant raised print on the substrate.
