FILM THICKNESS MEASUREMENT METHOD FOR MOLD RELEASE AGENT, COATING LIQUID USED IN SAID FILM THICKNESS MEASUREMENT METHOD, AND FLUORESCENCE INTENSITY MEASUREMENT INSTRUMENT USED IN SAID FILM THICKNESS MEASUREMENT METHOD

摘要

A film thickness measurement method for a mold release agent according to the present invention includes a coating formation step for forming a coating by applying a coating liquid including a fluorescent agent and a mold release agent onto a mold, an excitation light irradiation step for irradiating excitation light onto the coating formed on the mold and causing the coating to emit fluorescence, a fluorescence intensity detection step for detecting the intensity of the fluorescence emitted by the coating, and a coating thickness calculation step for calculating the thickness of the coating from the fluorescence intensity.
