Process for producing titanium dioxide pigment for photograph and photographic support comprising same |
| abstract |
Disclosed is a process for producing a titanium dioxide pigment used for a resin-coated paper type photographic support, comprising the following steps: (a) a step of adding at least one alkaline earth metal compound in an amount of 0.01-2.0% by weight in terms of a metal oxide based on the titanium dioxide before calcination step and (b) an acid-washing step of washing the titanium dioxide at acidic state after the calcination step and before a step of surface treatment with a hydrated metal oxide, and wherein particle size of the titanium dioxide pigment is 0.110-0.150 mu m shown by number-average diameter obtained by measuring the diameter in a certain direction using an electron microscope. A photographic support which comprises the above titanium dioxide pigment is also disclosed. Occurrence of die lip stain and microgrit are substantially reduced in the photographic support and a photographic material made thereof exhibits improved image sharpness. |
