Provided is a method capable of producing a retardation film suppressed in biaxiality, having a small Nz coefficient, and having a slow axis in an oblique direction with high production efficiency. The production method for a retardation film of the present invention includes: holding left and right side edge portions of a film to be stretched with left and right variable pitch-type clips configured to have clip pitches changing in a longitudinal direction, respectively; preheating the film; reducing, under a state in which a position at which the clip pitch of the clips on one side out of the left and right clips starts to reduce and a position at which the clip pitch of the clips on another side starts to reduce are set to different positions in the longitudinal direction, the clip pitch of each of the clips to a predetermined pitch to subject the film to oblique stretching; and releasing the clips holding the film.
摘要:
An interlayer comprised of a thermoplastic resin and at least one special effect metal pigment. The use of a thermoplastic resin and at least one special effect metal pigment provides a special effect metal appearance without sacrificing other characteristics of the interlayer, and wherein the color of the interlayer measured in reflectance mode is different from the color measured in transmission mode.

The present invention is a method for manufacturing inflatable bladders for use in articles of manufacture. The method includes the steps of providing a first polymer film, applying a curable release coating to the polymer film in a pattern that corresponds to the configuration of the inflatable bladder, curing the release coating to the first polymer film, providing a second polymer film with the first polymer film to form a layered element such that the release coating is disposed between the polymer films, positioning the layered element between two plies of material, applying heat and pressure to adhere the polymer films together except in the area where the release coating has been applied to form an inflatable compartment surrounded by a sealed perimeter, and removing the plies of material from the adhered first and second polymer films.
