Abstract
Ink and coating compositions are disclosed comprising a silicon-treated carbon black. The silicon-treated carbon black may have at least one attached organic group, and the ink and coating compositions may comprise a combination of silicon-treated carbon black products, with and/or without at least one attached organic group, and untreated carbon black. Methods are disclosed for improving the jetness, improving the blue tone, improving the platewear, reducing the premix residue, modifying rheological properties, or improving waterfastness, of ink and coating compositions by incorporating therein silicon-treated carbon black.
Claims30
A coating composition comprising a) an aggregate comprising a carbon phase and a silicon-containing species phase and b) an aqueous or non-aqueous solvent.
A method for improving the jetness of an ink or coating, comprising the step of incorporating in said ink or coating an aggregate comprising a carbon phase and a silicon-containing species phase.
A method for improving the blue tone of an ink or coating, comprising the step of incorporating in said ink or coating an aggregate comprising a carbon phase and a silicon-containing species phase.
A method for improving the platewear of an ink or coating, comprising the step of incorporating in said ink or coating an aggregate comprising a carbon phase and a silicon-containing species phase.
A method for reducing the premix residue of an ink or coating, comprising the step of incorporating in said ink or coating an aggregate comprising a carbon phase and a silicon-containing species phase.
A method for modifying rheological properties of an ink or coating, comprising the step of incorporating in said ink or coating an aggregate comprising a carbon phase and a silicon-containing species phase.
A method for improving the waterfastness of an ink or coating, comprising the step of incorporating in said ink or coating an aggregate comprising a carbon phase and a silicon-containing species phase.
