Pyrazolone Color Coupler for Photographic Paper from China

This is a pyrazole-based heterocyclic compound used as a color coupler in color negative photographic paper, reacting with oxidized developer to form magenta dye images during processing. It falls under HTS 2933.19.30.10 as an aromatic pyrazole derivative specifically designated for photographic chemical applications in color negative paper. The chemical structure contains an unfused pyrazole ring essential for its coupling function in silver halide emulsions.

Import Tips

Verify the coupler's specific use certification for color negative photographic paper to qualify under this HTS subheading; general pyrazoles classify differently

Include technical data sheets proving pyrazole structure and aromatic modification, plus end-use declaration to avoid reclassification
