ABSTRACT:
Containers or pods for photographic processing material, having strong seals along certain edge areas, and relatively weaker seals along other edge areas. The weaker seals are designed to open and distribute material over a sheet of film and/or paper when pressure is applied within a camera. The weak seal material is a thermoplastic crosslinked homopolymer of a norbornene compound having the structure: ##STR1## wherein R' is selected from the group consisting of a hydrogen atom, a monovalent aliphatic group of from 1 to 4 carbons, and a phenyl group, R" is selected from the group consisting of a hydrogen atom and a monovalent aliphatic group of from 1 to 2 carbons, and n is 0 to 3. Seals made with these homopolymers are highly resistant to the dissolving action of aromatic alcohols such as benzyl alcohol.
