It was proposed that in the staining process allylamine diffuses into amorphous region of PET film

reacting slightly with ester bond on PET chain and connecting with it and remaining in the amorphous area

then OsO4 reacts with C=C group in allylamine

deposits in that region and hence

increases the contrast between amorphous and crystalline regions.
