Pattern-bearing sheet for use in simultaneous injection-molding and pattern-forming method

Abstract

A pattern-bearing sheet for a simultaneous injection-molding and pattern-forming method, has a sufficient malleability in the following conditions. When the sheet is cut to a 10-mm width and subjected to a tensile load and thus elongated at a rate of 30%/second in an environment at 50.degree. C., the sheet should exhibit a stress value of 0.6 kg or higher at the yield point and after passing through the yield point in the case where the sheet is formed from a material having a yield point, and the sheet should exhibit a stress value of 0.6 kg or higher at an elongation of 10% and higher in the case where the sheet is formed from a material not having a yield point. Desirably, the value when the sheet cut to 10-mm width is elongated at a rate of 7%/second to an elongation of 200% (200% modulus value) at a temperature of 100.degree. C. to 120.degree. C. should be 0.3 kg or lower.
