ABSTRACT:
The recording carrier is metallized, typically with aluminum. Between the aluminum and the paper is an intermediate layer made of lacquer or printing ink, or both. The aluminum coating has a metallically shiny surface which reduces contrast. To increase contrast upon recording by burning off the aluminum, the surface of the intermediate layer is made matte by an organic additive which, when subject to electrical discharge, burns with little or no residue. The matte surface of the intermediate layer also decreases the gloss or shine of the overall carrier since it will affect the surface characteristics of the aluminum layer thereover.
