    摘要: Solvent-free, energy curable flexographic printing inks which contain a pigment; a rheological additive having the structure P-(U-Y)s, wherein P is the residue of an organic pigment or dye, Y is a polyalkylene oxide moiety, U is a linking moiety covalently bonding Y to P and s is an integer from 1 to 3; and an energy curable liquid vehicle which may be a ultraviolet cationic or a free radical initiated polymerization system, cured by actinic radiation; and optionally containing a photoinitiating system.

    摘要: A display pixel (10, 50). The pixel (10, 50) includes first and second substrates (12, 20, 60, 62) arranged to define a channel (16, 74). A fluid (26, 76) is located within the channel (12, 74) and includes a first colorant (36, 84) and a second colorant (38, 86). The first colorant (36, 84) has a first charge and color. The second colorant (38, 86) has a second charge that is opposite in polarity to the first change and a color that is complementary to the color of the first colorant (36, 84). A first electrode (22, 66), with a voltage source (32, 78), is operably coupled to the fluid (26, 76) and configured to moving one or both of the first and second colorants (36, 38, 84, 86) within the fluid (26, 76) and alter at least one spectral property of the pixel (10, 50).
