Patent ID: 7210799

Claim:
A process for the production of a plate, in particular a motor vehicle licence plate, in which initially at least one layer sequence forming an electroluminescence flat capacitor ( 4 , 5 , 6 , 7 ) and thereafter a reflection film ( 10 ; 10 ′) which is translucent for the light of the electroluminescence flat capacitor ( 4 , 5 , 6 , 7 ) are applied to a carrier ( 1 ), wherein the reflection value of the reflection film ( 10 ; 10 ′) is higher than the maximum statutory permissible value, and said reflection value is reduced by further production steps to such an extent that it is below the maximum statutory permissible value, characterised in that a reflection film ( 10 ) is used whose reflection properties are based on it having on its rear side rearwardly projecting prismatic structures ( 12 ), at the interfaces of which the light incident from the front side is reflected by total reflection, and that the further production steps involve applying the reflection film ( 10 ) to an adhesive layer ( 9 ) which is translucent in respect of the light of the electroluminescence flat capacitor ( 4 , 5 , 6 , 7 ) and is of approximately the same optical refractive index as the rearwardly projecting prismatic structures ( 12 ) of the reflection film ( 10 ), and in that situation the intermediate spaces between the prismatic structures ( 12 ) are partially filled by the adhesive to such an extent that the reflection value of the reflection film ( 10 ) is reduced in the desired manner.
