Optical Brightener Fluorescent Dye
Optical
brightener is not strictly a dye, since it is not coloured of itself. Instead it
has a strong blue fluorescence which enables it to make fabrics look whiter (the
blue whitener effect), and also
causes the well known blue fluorescent effect seen on clothing under ultraviolet
illumination such as disco dark light. Optical brightener is applied to textiles
by soaking. The product is suitable for use on cotton and synthetics.
Scuddlebutt Optical Brightener is a stilbene / triazine type brightening agent. Fluorescent brighteners of this type make excellent laser dyes and although Scuddlebutt Optical Brightener is a commercial grade and not specifically offered for laser work, users have reported it to be a workable laser medium.
