ABSTRACT:
Dye-containing polymers wherein the dyes are organic in nature are incorporated into glasses produced by a sol-gel technique. The glasses may be inorganic or organic-modified metal oxide heteropolycondensates. The dye-containing polymers are covalently bonded to the glass through a linking group. The products of this invention can be used to make optically clear colored films which can be employed in the imaging, optical, solar heat energy and related arts.
