Low dielectric constant curable ink compositions

Curable ink compositions include a first monomer that is a branched alkyl (meth)acrylate monomer with 12 or more carbon atoms, an optional second monomer, a crosslinking monomer, and at least one initiator. The curable ink composition is solvent free and inkjet printable, having a viscosity of less...

Beschreibung
Zusammenfassung:	Curable ink compositions include a first monomer that is a branched alkyl (meth)acrylate monomer with 12 or more carbon atoms, an optional second monomer, a crosslinking monomer, and at least one initiator. The curable ink composition is solvent free and inkjet printable, having a viscosity of less than 30 centipoise at a temperature of from room temperature to less than 60 DEG C. Upon curing, a non-crystalline, optically clear layer with a dielectric constant of less than or equal to 3.0 at 1 megaHertz is formed.
