Thermal Ink Transfer Pad

Solid, spherical, low surface energy particles, such as finely divided perfluoroethylene powder or polyvinyl chloride powder, improve the transfer of marking material by release from a substrate.

The substrate functions as a physical support for the marking material until the printing operation. The marking material is laminated to the substrate and typically has organic resins or natural or artificial waxes as major ingredients. The addition of the low surface energy particles decreases the cohesion of the ink and also reduces the adhesion to the substrate.

Transfer of the marking material may be by impact, thermal or radiation effect, or other techniques. When the particles are used, release from the substrate in the character image is achieved at lower inputs.
