Abstract:
There are very few violet or pink colored commercial pigments that display high heat stability, resistance to acidic conditions, or good lightfastness. This technology results in pigments that fall into the above color space, but display improved chemical and weathering stability. The pigments based of this technology have the molar ratio (A2O)x(BO)y(C2O5)z(DO3)w(EO2)v, where 2x+y+2z+w+v≅100. Where A is Li or Li with one or more of Cu, Na, or K, where B is Co or Co with one or more of Ca, Cu, Fe, Mg, Mn, Ni, Sn, or Zn, where C is Nb, Sb, or combination thereof, where D is Mo, W or combination thereof, where E is Sn, Ti, Zr, or combination thereof. The above formulation may be modified with a dopant addition of Al, B, Ba, Bi, Ca, Ce, Cr, La, P, Pr, Si, Sr, Ta, V, or Y where the dopant concentration represents 5 atomic % or less of the total number of moles of components A+B+C+D+E.

Abstract:
This invention relates to products of aqueous and other chemical synthetic routes for encapsulation of a core material with an inorganic shell and finished compositions of a core-shell particulate material for application in thermoplastic, thermoset, and coatings resins prior to compounding or application or subsequent thermal processing steps. Disclosed is a composition of particles containing a shell of inorganic oxides or mixed-metal inorganic oxides and a core material of complex inorganic colored pigment, laser direct structuring additives, laser marking, or other beneficial metal oxides, metal compounds, or mixed-metal oxide materials, wherein the shell material is comprised of any single oxide or combination of oxides is taught. Preferred elements of composition for the shell are oxides and silicates of B, Ni, Zn, Al, Zr, Si, Sn, Bi, W, Mo, Cr, Mg, Mn, Ce, Ti, and Ba (or mixtures thereof). Applications may include, but are not limited to, coatings or plastic articles or materials for molded interconnect devices, durable goods, housings, assemblies, devices, and articles that are to be exposed to additional thermal processing. The resulting core-shell materials function in plastic and coatings formulations by minimizing or eliminating detrimental interactions with the resins and metal containing additives resulting in loss of mechanical properties.
