Invisible Fluorescent Chemicals

Below are actual photographs* of some of our high quality pigments or dyes. The left side shows the compound under normal (visible) light. The right side shows the same compound when exposed to ultraviolet light. We can integrate these compounds into a wide variety of materials such as inks, varnishes, plastics and adhesives so that they are undetectable under normal light. These materials have a wide variety of uses and are an excellent choice for process control and security applications.
