Abstract
The invention relates to high resolution video storage disks comprising a substrate having disposed thereon a film of a monofunctionalized substituted tetraheterofulvalene compound and a halocarbon. The tetraheterofulvalene compound can have the molecular formula ##STR1## where X can be S and/or Se R can be an alkyl group having from about 1 to about 8 carbon atoms or a benzyl group wherein said benzyl group can be a part of a polymer chain; and Y can be either an ester or an ether.
Claims8
A high resulution video storage disk comprising a substrate having disposed thereon a monofunctionally substituted tetraheterofulvanene and a halocarbon having a high electron affinity for photo-reaction with said monofunctionality substituted tetraheterofulvalene, wherein said monofunctionally substituted tetraheterofulvalene having the molecular structure of:
- ##STR3## wherein X is selected from the group consisting of S and Se;
- R is selected from the group consisting an alkyl group having from about 1 to about 8 carbon atoms, benzyl, and a benzyl group which is part of a polymer chain;
- and
- Y is selected from the group consisting of an ester or ether group.
