A stainproof part and a fog-resistant part including a crosslinked hydrophilic film prepared by forming a film on a substrate from a hydrophilic film-forming composition containing a crosslinking agent and a hydrophilic polymer having a crosslinkable group at one terminal, and hardening the film by heat or light. In a favorable embodiment, multiple, at least mutually-reactive crosslinking agents are used as the crosslinking agent, and at least one of the multiple crosslinking agents has a functional group that can form a covalent bond and/or ionic bond with the hydrophilic polymer having a crosslinkable group at one terminal.
