ABSTRACT:
Pods for holding photographic solutions have strong edge seal areas and relatively weaker edge seal areas which are designed to break open when pressure is applied to the pod for releasing a photographic solution onto a sheet of paper or film. The weak seal is formed by applying a strip along an edge of a thermoplastic material which is a crosslinked homopolymer or copolymer of 2-acetoacetoxyethyl methacrylate. The homopolymer can be crosslinked by heat, or by the action of formaldehyde, glyoxal, glutaraldehyde, or ethylene diamine. The 2-acetoacetoxyethyl methacrylate also can be copolymerized with a 2-norbornylmethyl ester of methacrylic acid and then crosslinked.
