I dont know, I read ilfochrome is stronger than any other photograph medium. Ilford Switzerland reports that. May be you are right. May be we must print on warm glass with alcohol and alcohol evoprates fast and leave the dye on subbed polyester film or glass , than an autochrome protective lauer applies.
Is there anyone who knows which patent is the manufacturing one at above list ?
