Product brochure
Fluorescent pigments absorb part of the light, including UV, and emit it back at a longer wavelength close to their own hue. That extra emission makes them brighter than any conventional pigment. They show best over a white ground and lose punch when mixed with off-shades. The brochure lists five series, HK, HP, HT, HW and HX, with heat resistance grades stated from 160°C up to 250°C and 280°C.

Solvent and general purpose
Bright grades for printing and screen inks, paints and general coloring, where the white ground and the shade matter more than process temperature.
Aqueous · custom matches
Grades for aqueous binders and specialty uses, in any shade on the card. Where the card falls short, the division makes a custom match from the sample you send.
Buying it right
Blue is a hard fluorescent shade to keep vivid. A fluorescent blue color that looks right in the lab can turn flat once it meets the base resin or a colored ground.
Transcor offers two blues on its 14-shade card, Blue and Sapphire. Put them over a white ground and they reach a brightness no conventional blue pigment gives.
For plastics, choose a high temperature series. For screen and packaging inks, the general purpose grades fit. Send a target and the division can match it.
