|1. (WO2017038566) METHOD FOR PRODUCING CURED FILM|
|Applicants:||NISSHIN STEEL CO., LTD.
|Title:||METHOD FOR PRODUCING CURED FILM|
The present invention pertains to a method for producing a cured film having very good internal curability by irradiating an ink composition containing a bisacylphosphine oxide as a photopolymerization initiator with light from an LED light source. A long-wavelength light irradiation step for irradiating a coating film of an ink composition containing a polymerizable monomer and a bisacylphosphine oxide with light having a maximum peak wavelength of 390-440 nm from an LED light source is carried out in the method for producing a cured film.
