To provide a process for producing a hollow cylindrical or solid
cylindrical mold having a seamless patterned layer comprising a
fluoropolymer.
A process for producing a mold comprising a hollow cylindrical or solid
cylindrical substrate 12 and a patterned layer comprising a fluoropolymer
and having a pattern formed on its surface, which comprises a step of
forming a film 32 comprising a fluoropolymer so as to cover the
circumferential surface of the substrate 12 thereby to obtain a mold
precursor 30; and a step of rolling the mold precursor 30 in such a state
that the circumferential surface of the mold precursor 30 is pushed
against a surface of a heated original mold 40 having a pattern reverse
to the pattern of the patterned layer, to transfer the reversal pattern
of the original mold 40 to the film 32 comprising a fluoropolymer to form
the patterned layer.
