PRODUCTION OF DISPLAY
Document Type and Number:
Japanese Patent JP3460725
Kind Code:
B2
Abstract:
PURPOSE: To increase winding force by heating laminated resin films formed by adhering and laminating a thermoplastic resin film and stretched resin film respectively having specific thermal shrinkage at a temp. in a specific value range where the films shrink thermally.
CONSTITUTION: The thermoplastic resin film B which is transparent and is ≤2% in the thermal shrinkage in both longitudinal and transverse directions under heating for 5 minutes at 80 to 100°C is adhered and laminated on the printed front surface side of the thermoplastic resin film A which is a resin film printed with signals on the front surface and is ≤2% in the thermal shrinkage in both longitudinal and transverse directions under heating for 5 minutes at 80 to 120°C. The stretched resin film C which is 30 to 70% in the thermal shrinkage in the transverse direction and ≤20% in the longitudinal direction under heating for 5 minutes at 80 to 100°C is adhered and laminated on the rear surface opposite from the printed surface of the thermoplastic resin film A. The laminated resin films are heated at ≤120°C which is the temp. at which the stretched resin film C thermally shrinks without restraining the laminated resin films.
