Abstract
Abstract The preparation of dye-silane compositions are disclosed. A dye-silane compound is formed in which the dye is covalently bonded to a cyano silane compound. These dye-silane polymer compositions have particular utility as dye adduct reactants in the preparation of dye containing polysiloxanes.
