Title:
DISRUPTIVE CONTAINER FOR LIQUID RETENTION
Document Type and Number:
Japanese Patent JPS5570844
Kind Code:
A
Abstract:
Disclosed herein are containers (C) for holding fluids, e.g. photographic processing materials, in photographic film units. The containers (C) have strong seals along certain marginal areas (13) and relatively weak seals along other marginal areas. The weak seals are designed to open and distribute fluid over a sheet of film or paper when pressure is applied to the container in a camera. Each weak seal is formed from a sealing composition comprising a copolymer of (a) at least 50 percent, by weight, of a polymerizablewherein n is an integer of from 0 to 3; R' is hydrogen or alkyl; and R2 is hydrogen, alkyl or phenyl; with (b) a copolymeriz-wherein R' is alkyl. This copolymer has a glass transistion temperature of at least 80°C.
