METHOD OF FORMING MASKING FILM HAVING PARTITION PATTERN

摘要

[PROBLEMS] To provide a method of forming a masking film applicable to both of blasting and etching. [MEANS FOR SOLVING PROBLEMS] The method comprises: a step (A) in which a PVC sheet (1) disposed on a release paper (2) is partly cut out so as to leave given partition pattern formation parts (11), with the release paper left on the back side; a step (B<SUB>1</SUB>) in which a low-tack application sheet (3) is pressed-bonded to the front side of the masking sheet (1) which has been cut so as to have the partition pattern formation parts (11); a step (B<SUB>2</SUB>) in which the release paper (2) is stripped from the three-layered sheet material having the application sheet (3) on one side; a step (C) in which an adhesive (5) is applied to the masking sheet (1); a step (D) in which the masking sheet (1) coated with the adhesive (5) is press-bonded to a surface of a panel (7) through the adhesive (5); and a step (E) in which the application sheet (3) is stripped from the masking sheet (1) in the state of being press-bonded to the panel (7) surface.
