A process for forming a light-reflecting bar code on an end disc of photographic film spool is performed by the steps of placing on the end disc of photographic film spool a hot-stamp film comprising, in order, an adhesive layer, a light-reflecting metal layer, a transparent protective layer, a releasing layer, a support film, and a stain-shielding layer formed of material inhibiting migration of a compound having a low molecular weight from the support film (e.g., compound having a siloxane bonding or deposited inorganic oxide) in such manner that the adhesive layer is brought into contact with the end disc, and pressing for 0.1 to 2.0 seconds a stamper having a heated bar code-stamping die, so as to transfer the light-reflecting metal layer onto the end disc in the form of the bar code.
