Patent ID: 8173739

Claim:
An additive composition made by combining: (a) at least one dispersant; (b) inorganic particulates having an average particle size in the range up to about 100 nanometers, the inorganic particulates having an index of refraction in the range from about 1.4 to about 3; (c) at least one phenylalkoxysilane, biphenol, trisilanolphenyl polyhedral oligomeric silesquioxane, or a mixture of two or more thereof; and (d) at least one dye concentrate comprising (i) at least one dispersant, (ii) at least one bluing agent, and (iii) inorganic particulates having an average particle size in the range up to about 100 nanometers, the inorganic particulates having an index of refraction in the range from about 1.4 to about 3; with the proviso that when the trisilanolphenyl polyhedral oligomeric silesquioxane is in the form of particulates with an average particle size up to about 100 nanometers, the trisilanolphenyl polyhedral oligomeric silesquioxane particulates are optionally used both as component (c) and as a partial or complete replacement for component (b).
