Photographic and Photolithographic systems are provided which utilize diacetylenic materials as components thereof. Such materials, which include at least two acetylenic bonds in conjugation with one another, provide a combination of both high sensitivity and high resolving power, thus resulting in superior photographic and photolithographic properties. In accordance with a preferred embodiment of the invention, a substrate is coated with at least one layer of a polymerizable composition comprising a diacetylenic species, said layer being organized into a plurality of domains having a substantially regular array of the diacetylenic species. In other embodiments, covalent bonding of the diacetylenic layer to the substrate is accomplished through the use of suitably constituted silane species, thus to provide a highly beneficial adhesion of substrate and photo- or photolithographic layer.
A photographic or photolithographic article comprising a substrate and at least one substantially continuous layer on said substrate of a polymerizable composition comprising at least one material having at least two acetylenic bonds, at least two of said bonds being in conjugation with one another, said layer comprising a plurality of domains, each of said domains having average dimensions less than 10,000 Angstroms and having a substantially regular array of said composition, so that said layer is imagewise polymerizable with improved resolving power upon the application of radiation to selected portions thereof.
