A cationized supporting material 2 is immersed into a treatment solution
containing a level dyeing agent, and then immersed into a treatment
solution containing a metal phthalocyanine complex and then dried to
thereby obtain an odor eliminating material 1. Alternatively, a
cationized supporting material 2 is immersed into a treatment solution
containing a metal phthalocyanine complex and a migration inhibitor and
then dried to thereby obtain an odor eliminating material 1. The odor
eliminating material exerts excellent odor elimination performance
against ammonia, hydrogen sulfide, methyl mercaptan, acetic acid and
acetaldehyde.
