  • Transfer sheet
    Patent number: 6136494
    Abstract: A transfer sheet comprising not less that 75% by mass of a polycarbonate resin, and having a ratio of an infrared absorbency at a wave-number of 155 mm.sup.-1 to that at a wave-number of 160 mm.sup.-1 of not less than 0.02 and less than 0.3, a melting viscosity of not less than 2,500 Pa.multidot.s when measured at 280.degree. C. by a Koka-type flow tester and thickness of 130 to 250 .mu.m. The transfer sheet can satisfy requirements of a mechanical durability, flame retardant properties and a modability simultaneously.
