The present invention relates to novel amine terminated cycloaliphatic polysiloxanes, and preparations thereof. More particularly, the invention provides several reaction schemes for the synthesis of amino-functionalized cyclo-aliphatic silicones and the products produced by the reaction schemes. In one embodiment of the invention, an amine functionalized silicone is prepared through a base-catalyzed ring-opening reaction. In another embodiment of the invention, an amine functionalized silicone is prepared through the hydrosilation of a silicone oligomer through the blocking and deblocking of an amine terminated in a vinyl group.

Disclosed is a method of recovering inorganic pigment such as TiO 2 from a coating composition that includes liquid, an organic component, and an inorganic component. The coating composition is thermally treated to remove at least a portion of the organic component and yield an inorganic pigment composition having a higher concentration of the inorganic pigment (TiO 2 ) than in the original coating composition.

A wavelength selective ophthalmic lens which utilizes coloring or tinting to filter selective wavelengths and thereby provide treatment of various conditions. A base lens of a first corrective power may include a plurality of raised lenslets on its surface, each of the lenslets being of a second corrective power that is different from the first corrective power. The coloring or tinting may be applied to one or more of the lenslets disposed on the base lens. The coloring or tinting may be applied to the base lens, to a laminate applied to the base lens, or to the lenslets themselves. The coloring may be applied using dyes, pigments, or the like. Various patterns of colored or tinted lenslets may be utilized, including patterns forming concentric rings or the like.
