Abstract
A method for preparing a polarizing substrate comprising a dye layer in which the substrate is contacted with a first solution having a organic silane at a temperature greater than room temperature.
Claims20
A method for preparing a polarizing substrate disposed on a surface of the substrate, the method comprising:
- contacting the substrate with a first solution comprising a first organic silane, wherein the first organic silane comprises one or more reactive functional groups;
- and the first solution is applied to the substrate, and the first solution is at a temperature greater than about 20 degrees Celsius.
A method for preparing a polarizing article comprising:
- providing a light-transmitting substrate;
- providing an aqueous polarizing dye solution;
- coating at least one surface of the substrate with the aqueous polarizing dye solution to form a dye layer;
- insolubilizing the polarizing coating with a stabilizing solution to provide a insolubilized polarizing coating;
- treating the insolubilized polarizing coating with a first silane solution at a temperature greater than room temperature to provide a solution treated polarizing coating;
- and
- curing the solution treated polarizing coating to form the polarizing article.
