Abstract (en)
[origin: EP1217437A2] An ultraviolet shielding filter agent, which contains fine-particle titanium oxide, and which satisfies the following condition (A), (B) or (C): (A) that the fine-particle titanium oxide has an average primary particle diameter or average primary short-axis particle diameter of 1 to 45 nm and is surface-treated with a specific amount of aluminum oxide and/or silicon dioxide, and that the ultraviolet shielding filter agent further comprises a polyhydric alcohol; (B) that the fine-particle titanium oxide has an average primary particle diameter or average primary short-axis particle diameter from 1 to 45 nm, and has rutile crystallinity from 20 to 70%, and that the ultraviolet shielding filter agent further comprises a polyhydric alcohol; or (C) that the fine-particle titanium oxide has a primary particle shape of a cylindrical shape or a spindle shape, and that among average primary particle diameters of the fine-particle titanium oxide, a short-axis diameter is from 1 to 45 nm, a long-axis diameter is from 3 to 200 nm, and a ratio of the long-axis diameter to the short-axis diameter is from 2 to 10. A color diffusion transfer photographic film unit, which uses the ultraviolet shielding filter agent.
