5-butoxy-2-[4-(4-butoxy-2-hydroxyphenyl)-6-(2,4-dibutoxyphenyl)-1,3,5-triazin-2-yl]phenol
PowerSorb™ 460 is a UV light absorber of the hydroxyphenyl-triazine class. Due to its extremely high extinction, it provides outstanding protection to coatings and light sensitive substrates and materials. It is therefore especially suited for use in silver halide photographic papers or overprint varnishes.

The key features and benefits of PowerSorb™ 460 contains:
- Solid hydroxyphenyl-triazine UVA;
- Extremely high extinction in the UV-A region enables photoprotection of thin films;
- Excellent photopermanence;
- Low color.
PowerSorb™ 460 is a UV light absorber of the hydroxyphenyl-triazine class. Since its absorption spectrum does not tail significantly into the visible region, it is an ideal UV absorber chemical for those systems where initial yellowing must be kept to a minimum.
PowerSorb™ 460 is recommended for use in:
- Silver halide photographic materials such as color negative papers;
- Overprint varnishes for commercial, publication, or packaging applications;
- Industrial coatings;
- Trade sale paints such as wood stains or do-it-yourself paints.
In photographic applications, PowerSorb™ 460 can be combined with other UV absorbers, such as PowerSorb™ 460, to achieve desired absorption characteristics.
In silver halide color negative papers, it is particularly useful for protecting the dyes and couplers from harmful UV light.
The triazine UV absorber can also be used in other reprographic applications in which organic UV filters are needed e.g., in non-silver imaging color hardcopy.
The amount of PowerSorb™ 460 required for optimum performance should be determined in laboratory trials covering a concentration range.
Recommend Concentrations:
0.5 – 3% PowerSorb™ 460 + 0.5 – 2.0 % PowerSorb™ 123, PowerNox™ 1425 or PowerStab™ 292
