Title:
SHEET FOR IN-MOLD DECORATING INJECTION MOLDING AND DECORATING METHOD USING THE SHEET
Document Type and Number:
Japanese Patent JP2690258
Kind Code:
B2
Abstract:
PURPOSE: To prevent occurrence of excessive deformation, flow, breakage, and the like in a decorative sheet even in deep draw decorating by using a sheet having a specific stress value after a yield point in tension as a decorative sheet used for in-mold decorating injection molding.
CONSTITUTION: A decorative sheet for use is a sheet having a stress value of 0.6 kg or more after a yield point in tension at a speed of 30%/see under an enviroment of 50°C when being cut to 10 mm in width. On the other hand, in the use of a sheet having no yield point, the sheet has a stress value of 0.6kg or more after a 10% elongation in tension under the same conditions. Furthermore, a sheet having a 200% modulus of 0.3kg or less in tension at a speed of 7%/sec at 100-120°C when being cut to 10mm in width is superior in moldability at the time of preforming, such as pressure forming.
