METHOD OF DRYING COATING FILM AND PROCESS FOR PRODUCING LITHOGRAPHIC PRINTING PLATE PRECURSOR

摘要

A method for drying a coating film according to the present invention aims to suppress development of abnormal appearance and performance failures produced on a product surface when a solvent of a coating liquid is dried while vapor of a solvent having a boiling point lower than that of the solvent of the coating liquid is sprayed to the coating film with a vapor spray nozzle within a drying box. For this, the method for drying a coating film according to the present invention, includes: drying a coating film to a drying point, the coating film which is formed by applying a coating liquid containing a high boiling point solvent onto a support to be conveyed; and subsequently, drying the high boiling point solvent while spraying vapor of a solvent having a boiling point lower than that of the high boiling point solvent to the coating film with a vapor spray nozzle within a drying box, wherein the support is heated so as to have a predetermined temperature T within the drying box, and conveyed.
