Abstract
Abstract The invention disclosed in this application is the use of novel silanes in curable coatings to allow tinting or dyeing of the coatings after they are cured on certain substrates. An example of one such useful silane is <IMAGE> The silanes and the curable coatings are also useful as antistat and antifog coatings.
