Description

METHOD FOR APPLYING ARTWORK TO METAL OBJECTS AND ARTICLES
COMPRISING SAME
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This Application claims the benefit of U.S. Provisional Application No. 62/353,646, filed on June 23, 2016, which is incorporated herein by reference in its entirety.
BACKGROUND
[0002] Powder coating is a process that is used widely around the world and generally consists of spraying an electrically charged powder onto a metal object. After the spray is complete, the object is then placed in an oven for a certain amount of time at a certain temperature.
[0003] Sublimation is a process that is used on a daily basis with different items around the world. Sublimation is a process that turns a dry ink into a gas while bypassing the liquid state. The only thing sublimation ink will stick to is polyester and only under high temperature and high pressure conditions for a certain amount of time.
[0004] Combining the methods of powder coating with sublimation in a manner that easily allows providing an artwork design on a powder coated surface of a metal object has not been available. In particular, the curing the powder coating results in surface properties such that the methods for transferring the artwork via sublimation transfer are compromised. For example, in attempting to combine these two methods in a facile manufacturing process, the skilled artisan is confronted with either incomplete transfer of the artwork or damage to the powder coated surface.
[0005] The present disclosure provides methods for easily transferring artwork via sublimation transfer to a powder coated surface, and articles manufactured using the disclosed methods.
