The invention discloses a composition of a color high-concentration mono-color master batch for polyolefin. Carrier resin is polyolefin resin, and the polyolefin resin comprises metallocene polyolefin resin. The composition further comprises a toner and an additive, wherein the additive comprises a dispersing agent, a lubricating agent, a coupling agent, a compatilizer and a stabilizer, or a mixture of at least two of the dispersing agent, the lubricating agent, the coupling agent, the compatilizer and the stabilizer.

New and useful low viscosity polymeric colorant formulations are provided comprising extremely low amounts of viscosity modifiers that drastically reduce the overall viscosity of the resultant colorant formulation as compared with the viscosity of the colorants themselves. In such a manner, the resultant formulation facilitates the utilization of such polymeric colorants within certain coloring processes and methods requiring low viscosity formulations while simultaneously permitting substantial retention of the same high color strength characteristics of the unmodified colorants. Such an unexpected result thus permits production and utilization of a low viscosity formulation that does not sacrifice colorability to an appreciable degree for target substrates or media. The inventive formulations thus comprise any number of polymeric colorants, (i.e., oxyalkylenated colorants comprising at least one chromophore constituent and at least oxyalkylene chain) and at least one viscosity modifying agent possessing a dipole moment of between 1.0 and 5.0 and/or a flash point of from about -20° C. to about 180° C. Such a modifying agent provides a significant reduction in viscosity at low levels (to permit better pumpability of the desired colorants) with no appreciable differences in coloring performance within final target media, and facilitates removal of such modifiers during or after utilization. Methods of production, utilization, and products produced with such formulations and by such methods are also encompassed within this invention.

The invention refers to a flexographic printing process with wet on wet capability based on controlled polymer or polymer segment precipitation that leads to gel formation of ink compounds by controlling the solubility parameter of the ink system. The mechanism to obtain a desirable wet on wet color trapping is the formation and/or presence of a gel in the applied ink film due to a controlled physicochemical mechanism of resin precipitation. This is accomplished either by controlling a change in the Hansen Solubility Parameter of the liquid in the ink through evaporation of some or all of a non-reactive and volatile solvent, or alternatively by use of a polymer comprised of two distinct and separate segments one of which is soluble in the monomer/oligomer mix and the other of which is not. The insoluble segments form a reversible gel that is broken to a liquid by shear in the application process, allowing application of a liquid ink, and is reestablished in the applied ink film in such a manner and with such strength as to allow overprinting in the wet on wet flexographic printing process.
