NEGATIVE AND POSITIVE FILM MANUFACTURING SHEET

摘要

PROBLEM TO BE SOLVED: To manufacture with good accuracy negative and positive films of high definition and high tone pattern and of superior durability in a manufacturing method for manufacturing the negative and positive films by using a release ribbon and releasing by a thermal transfer printer. SOLUTION: A transparent thermoplastic release agent of melting point of 40-85 deg.C is applied on one face of a transparent base film. Then an ultraviolet shielding resin layer composed of nixed resin formed of carbon black dispersed ethylene acetate vinyl copolymerized resin into which carbon black having an oil absorption of 101ml/100g and a particle size of 20-40mμ are dispersed and blended by the solid content weight ratio of 50-60wt.% and ketone resin and polyethylene wax is laminate-applied on a release agent coated surface.
