Abstract: This disclosure relates to a photosensitive composition useful in preparing water-developable, relief printing plates and other photosensitive articles. The compositions comprise an unsaturated polyurethane pre-polymer, which is the reaction product of at least one polyether diol, at least one aliphatic diisocyanate, at least one hydroxyl-functionalized mono-, di- and tri-(meth)acrylate, and a particular photoinitiator. The resulting photosensitive resin compositions have reduced rates and levels of yellowing if subjected to additional UV-light or sunlight after processing.

Abstract: A swab applicator for containing and dispensing cyanoacrylate adhesives is disclosed. The device comprises a tube applicator with a valve to contain the cyanoacrylate until use. The valve can be a ball, a bead or a capsule, or it can be an oblong object having a channel closed at one end. The device further comprises an absorbent material which is saturated by cyanoacrylate for application upon opening of the valve. The device can be heat sterilized using dry heat sterilization without rupturing prematurely from pressure generated during the sterilization process.
