Abstract: A non-aqueous sealant composition particularly adapted for use in the installation or sealing of fixed glass in vehicles. The composition has a thermoplastic rubber base, suitably modified by plasticizers, tackifyers and a cationic surfactant to provide a sealant system which displaces water from a wetted substrate to which it is applied, permitting it to be utilized under either wet or dry conditions.

Abstract: This invention relates to free-radical, non-silver, photosensitive films, particularly those suitable for optical development as described in U.S. Pat. No. 3,510,300. The invention comprises the incorporation of compounds which contain an imine (--C.dbd.N--) function and a hydroxyl group into otherwise known photosensitive compositions to improve optical development and to retard dark fogging so as to thereby provide aging stability to such compositions. Preferably, an additional improvement comprises provision of an overcoat for the photosensitive composition of this invention when in the form of thin films on a support such as a polyester or a paper sheet or glass plate. The overcoat acts to improve the shelf life and photosensitometric properties of the photosensitive composition.
