ABSTRACT:
This invention provides an improved coating composition for glass substrates that comprises a tetrasubstituted compound. The introduction of a tetrasubstituted compound in a coating composition for a glass substrate, and in particular an optical fiber, acts to delay the rate of deterioration of the glass or optical fiber due to moisture, and improves adhesion between the glass substrate and the coating composition. The introduction of a tetrasubstituted compound into a polymeric coating composition also improves the interlayer adhesion when more than one coating is applied to a glass substrate. This invention further relates to an outer primary coating composition or matrix material that comprises an acid functional ethylenically unsaturated monomer. This invention also provides an improved coated glass substrate having a decreased rate of deterioration due to moisture, improved adhesion between the glass substrate and the coating composition and between the various coatings, wherein the coating composition comprises a tetrasubstituted compound.
