PROCESS FOR PRODUCING MOLD

摘要

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.
