Paper for photographic purposes |
(57) A paper for photographic containing a nonionic antifoamer of which the components
do not include silicone nor propylene oxide, a paper for photograph containing a nonionic
mineral oil antifoamer of which the components include silicone or silicone-modified
silica and having a pH of 3.5 to 5.5 measured by the cool water extracting method,
and a paper for photograph which contains a water-soluble aluminum salt and at least
one of rosin sizing agent, polyacrylamide or polyamide-epoxy resin and has a pH of
3.5 to 6.0 measured by the cool water extracting method. 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.
