Abstract
A process for applying a metallic appearance to a plastic substrate comprising providing a metallic printing ink comprising a approximately 5 to 30% for metallic dispersion component comprising metallic particles, and approximately 70 to 95% of a solvent based ink component, applying the metallic printing ink onto the plastic substrate and evaporatively curing the metallic printing ink onto the plastic substrate for approximately 10 to 15 seconds between approximately 200.degree. F. and 300.degree. F., such that the plastic substrate has a metallic appearance.
Claims19
A process for applying a metallic appearance to a plastic substrate comprising:
- (a) providing a metallic printing ink comprising;
- (i) a metallic dispersion component comprising metallic particles;
- and
- (ii) a solvent based ink component;
- (b) applying the metallic printing ink onto the plastic substrate;
- and
- (c) evaporatively curing the metallic printing ink onto the plastic substrate at temperatures between approximately 200.degree. F. to 300.degree. F. for approximately 10 to 15 seconds.
An ink composition comprising:
- (a) approximately 5 to 30% by weight of a metallic dispersion component comprising a dispersion solvent and metallic particles, wherein the metallic particles comprise approximately 5% to 15% by weight of the metallic dispersion component;
- and
- (b) approximately 70 to 95% by weight of a solvent based ink component comprising an ink solvent, said dispersion solvent and said ink solvent being compatible with each other;
- wherein the ink composition provides a metallic appearance when evaporatively cured onto plastic substrates.
