at least one photographic emulsion layer, there being coated on the topmost emulsion
layer a gelatin supercoat layer which comprises from 5 to 35% by weight of colourless
polymer particles which have a glass transition temperature (Tg) of at least 40°C
and have a particle size of not more than 90nm and have substantially the same refractive
index as gelatin.
The object of the coating is to produce a high gloss and reduce the haze.
