Films of a light sensitive element having a support polyethylene terephthalate containing barium sulfate particles

摘要

Light-sensitive imaging materials comprise a white opaque oriented support film of a polyester, e.g. polyethylene terephthalate, containing a high amount of filler particles comprising barium sulphate, i.e. from 5 to 50% by weight, having an average particle size from 0.5 to 10 mu m, and a light-sensitive imaging layer, e.g. a photographic emulsion, applied to the support film.
