titleOfInvention |
Oxygen barrier coated photographic coupler dispersion particles for enhanced dye-stability |
abstract |
The invention creates a selective oxygen barrier around individual coupler or other photographically active particles by surrounding each particle with a layer of water applicable oxygen barrier polymer such as polyvinyl alcohol (PVA), which will also act as a steric barrier to coalescence of the particles. Photographic products formed with such materials are more dye stable. |
