  • Energy curable gravure inks incorporating grafted pigments
    Patent number: 6727295
    Abstract: Solvent-free, energy curable low viscosity gravure and non-conductive ink jet 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 cationic, thermal cationic or a free radical initiated polymerization system, cured by actinic radiation; and optionally containing a photoinitiating system.
    Type: Grant

  • Imaged printing plate and method of preparation
    Patent number: 6670084
    Abstract: A printing plate useful in lithographic printing is prepared by a process comprising: (a) applying a coating composition comprising at least one polymer such as polyethylene glycol to a substrate surface to provide the surface with a water-soluble or water-dispersible polymer coating; (b) imaging the coated substrate with a toner composition comprising toner particles by imagewise applying the toner composition to the polymer coating, wherein the polymer coating has a softening temperature TS; (c) heating the imaged substrate to a temperature TF which is equal to or greater than TS; and (d) contacting the imaged substrate with a solution capable of removing the non-imaged portion of the polymer coating, wherein the process does not comprise a chemical development step and the polymer coating has a coating weight of about 0.25 to about 2.0 g/m2.
