    摘要: In one embodiment, the present invention relates to a KOH neutralized metatitanic acid mixture containing from about 30% to about 99% by weight metatitanic acid, from about 1% to about 20% by weight of a titanyl compound, and optionally from about 0% to about 55% by weight titanium dioxide, wherein the KOH neutralized metatitanic acid mixture has a pH from about 4 to about 6.5. In another embodiment, the present invention relates to a pigment composition made by combining a KOH neutralized metatitanic acid mixture and at least one guest element precursor, wherein the KOH neutralized metatitanic acid mixture contains metatitanic acid, a titanyl compound, and optionally titanium dioxide, the KOH neutralized metatitanic acid mixture having a pH from about 4 to about 6.5.
