摘要： This invention provides a hydrophilic membrane wherein a hydrophilic cellulose derivative of a number average molecular weight of 2000∼8000 is adsorbed irreversibly to a hydrophobic membrane of an aromatic polymer.
Since an amount of leaching substances is extremely small, the membrane can be used suitably in such fields as medical applications ,electronics, etc. where even a quite small quantity of leaching substances from the membranes is limited especially small.

摘要： A hydrophilic film comprising a hydrophobic aromatic polymer film and, adsorbed thereto irreversibly, a hydrophilic cellulose derivative with a number-average molecular weight of 2,000 to 8,000. As the film is remarkably reduced in exudates, it is usable also in the fields of medicines and electronics where exudates must be avoided.
