cholesteric liquid crystal (CLC) polymers/pigment,polarized
ink,liquid cationic polymer
CLC pigments are made from cholesteric liquid crystal (CLC)
polymers: crosslinked materials that have their molecules "locked"
in the cholesteric phase. This allows the unique optical properties
of a liquid crystal to be exploited in a solid pigment.
Â
Once a CLC polymer film is made, it is fractured into small
platelets that retain all the optical properties of the original
CLC phase, including "color flop" and polarization. These platelets
are the CLC pigments, and can be used to make color flop and
polarizing inks that have clear and dramatic printing effects.
Â
Color Flop Inks
The figure below demonstrates the effect of a color flop ink. As
the viewing angle increases, the reflected color "flops" - it
changes from red to green, for example.

Polarizing Inks
Polarizing inks are well suited for security applications using
covert detection. The photographs below show a picture printed with
the left-handed CLC pigments in red, green, and blue analyzed by
left-handed circular polarizer and right-handed polarizer,
respectively. The extinction is clear and obvious.

The circular polarization extinction effect can also be used in
high-speed machine-read detection mechanisms. A right- and
left-handed circular polarized detector set at the same wavelength
can detect the drastically different signals from the same location
indicating an authentic product. Because CLC can be made that are
reflective for ultraviolet, visible, and infrared light, this
effect can be utilized in non-visible systems.

Applications:
- Security: Banknote, secure
document, and brand protection labels and markings
- Decorative: Consumer
packaging, electronics, and white goods; automotive and other
vehicular applications
- Specialty: Color effect
inks, screen ink, cosmetics, 3D effects, and novelty products
Benefits:
- Pigments with excellent
color travel and circular polarization properties
- Thin pigment flakes (less
than 3 microns thick)
- Custom pigments with
unique properties such as multilayer, additive, or other effects
