Definitions

  • the present invention relates to an ink composition for release treatment surface marking, and more particularly, to an ink composition for release treatment surface marking in which a glycidyl group is introduced into a binder resin as a functional group.
  • a protective film is often used to protect the base film from mechanical damage or contamination during production, storage, and transportation during the use of various base films.
