In the above papers for photograph, silicone and propylene oxide which are harmful with respect to photographic properties are removed, or propylene oxide is removed and silicone is rendered harmless by adjusting the pH to an acidic range. Or, particular sizing agent and paper strongs agent less affecting photographic properties within a particular acidic range are selected.
