In this article a novel process for patterning of dye into a positive‐type novolac resin is reported by doping vapor of the blue dye, Solvent Blue 59 (SB59), using a simple vacuum process named the vapor transportation method. SB59‐doped novolac resin films were examined by UV‐vis absorption spectroscopy and optical microscopy. When SB59 vapor was doped into unexposed films at temperatures above 130°C, absorption peaks due to SB59 were detected. In contrast, no absorption peaks were detected when SB59 vapor was doped into exposed films. These results indicated the selective doping of SB59 vapor into unexposed novolac resin films. When SB59 vapor reached the surfaces of micropatterned novolac resin films with both unexposed and exposed areas, SB59 was doped selectively into the unexposed areas of the films, resulting in the production of micropatterns with SB59 molecules in the patterned films.
