what is aluminum pigment paint in the scratch cards of lottory?is it metalic or organic sabstance like latex?
Yes its aluminium metal. Finely divided aluminium powder is dispersed in a polymer resin as used for paint.
They mix aluminum or just about any opaquing material with a wax-like coating that will be easily scratched off. The early tries at this were defeated with strong lasars and cards could be read and be selected to be handed to confederates. Very fine AL power is available and is a safe product and is very opaque and cheep.
