ROCHESTER, NY – Eastman Kodak Company said it has been working with the Conductive Polymers Division of Heraeus Precious Metals to create technologically advanced transparent conductive films for use in touch screen and signage applications.

A 3.5" projected capacitive touch screen for use in cellular handsets is constructed with Kodak HCF-225 Film/ESTAR Base as the transparent conductive component, featuring invisible patterns.

The invisible patterning process uses Heraeus’ component technologies, whereby a conductive pattern is screen printed onto Kodak HCF-225 Film/ESTAR Base using Clevios SET S – a masking polymer.

Clevios Etch is then used to create the non-conductive areas. After the process is completed, the masking polymer that protected the conductive pattern is removed.
