Imaging Inks and Coatings
(Microencapsulated Leuco Dye Ink / Carbonless Paper Systems)
DESCRIPTION
Microencapsulated leuco dye ink is an aqueous-based ink product used primarily as the color component in imaging coated paper. The ink is nearly colorless as supplied, but turns to color, when the capsules are ruptured in the presence of a suitable activator. The microencapsulated ink makes an intensely colored copy but does not reactivate, which can cause dots to appear on the receiving page. This is an indication that the ink is 100% encapsulated with no leaky or unstable microcapsules. The capsule wall is an inert, very stable polymer or plastic.
APPLICATIONS
The microencapsulated ink is used in an imaging copy system and is available as the color component. The most common application for this technology is in carbonless paper systems. The microencapsulated leuco dye system can also be utilized for security applications, such as tamper evident detection.

PROPERTIES
The microencapsulated ink product exhibits the following general properties:
- Slight color that becomes nearly invisible, when coated on white paper
- Aqueous based slurry
- Capsule composition: ~85% capsule core and 15% capsule wall
- Particle size: Range of 1 to 10 microns with a mean size of 2 to 3
microns
- The slurry contains 40 to 45% solids
- The core material is a proprietary combination of solvents and dyes
which makes an intense color, when used with the activator in an
imaging system
