Abstract
A laminated core stock sheet for use in a composite laminate assembly that is separated into individual cards is provided. The sheet includes a core substrate layer and an intermediate filmic layer coupled to the core substrate layer. The intermediate filmic layer includes a conductive material that provides a security, decorative, or functional feature of the cards. The core substrate layer and the intermediate filmic layer are coupled with another laminated core stock sheet to form the composite laminate assembly. The conductive material has a small thickness within the intermediate filmic layer such that the intermediate filmic layer prevents conduction of electrostatic discharge (ESD) through the intermediate filmic layer and outside of the individual cards.
