TINUVIN® 171 is recommended for photographic applications. It is particularly suitable for chromogenic color papers to protect the dyes and couplers from harmful UV light.

One of the remarkable benefits of the liquid form of TINUVIN® 171 is avoidance of crystallization of the UV absorber in the liquid photographic emulsion preparation during storage and after coating. Consequently, it allows formulation of thinner layers or layers with increased UV light protecting properties through higher load of UV absorbers.

This product can also be used in repro and other photographic applications in which a UV filter is needed e.g. in non-silver imaging color hard copy.

The amount of TINUVIN® 171 required for optimum performance should be determined in trials covering a concentration range.
