A long running printing press can be obtained by use of a photopolymerizable composition comprised of an ethylenically unsaturated oligomer, a solvent soluble diazonium resin, an organic film forming binder, and a photoinitiator system in described ratios.

Photoreactive oligomer composition and printing plate

An information carrying element comprising a substrate having adhered to at least one surface thereof a separate layer having a thickness of 1.0 to 100 microns and a circular or spiral pattern of surface variations provides a particularly useful element when said separate layer comprises an abrasion resistant polymer layer derived from 30 to 100% by weight of an epoxy-terminated silane.

Information carrying discs

Imaged transparent film which is carried by machinery is provided with a low friction, abrasion resistant coating which prevents the film from causing unnecessary drag when used with the machinery.

Low friction, abrasion resistant coating for transparent film

Abrasion resistant coatings based on epoxy-terminated silanes can reduce the transmission of ultraviolet radiation by at least 90% with the addition of ultraviolet radiation absorbers and 10-70% by weight of an aliphatic, polyepoxide, comonomer.

Ultraviolet radiation protective, abrasion resistant, bloom resistant

Abrasion resistant coatings derived from epoxy-terminated silanes are desirable when formed by curing in the presence of PF.sub.5, SbF.sub.5, or HSbF.sub.6.
