I wonder why fuji instax's photographic paper won't fade when it is wet.

The material of Fuji Polaroid photographic paper is different from ordinary photographic paper. Fuji instax adopts the 80-year-old silver salt imaging principle inherited from fujifilm, and undergoes chemical reaction through silver halide sensitization. The process of photosensitive, developing and fixing is completed by developer and fixer contained in photographic paper, and there is a film on the surface, which can be preserved for decades even in harsh environment. So, your photo is not damaged. ?
