Information about RAUDOCOP film please

I've just read of a "Transparent photographic paper with antihalo coating and orthochromatic emulsion". I think it is called RAUDOCOP Hialino negtor. I think it is used in the textile industry.
It is used by Gabriel Lacomba as a negative material in cameras.

Does anyone have further information about this film???

With thanks,

Does a transparent paper need an AH-coating?
