Abstract
(EN)
A protective film for exterior vehicular trims which comprises a base layer comprising a thermoplastic resin that has no urethane bonds in the molecule and has a softening point in the range of 40-150°C, a skin layer disposed on one surface of the base layer and having a haze of 20% or less, an adhesive layer disposed on the reverse side of the base layer from the skin layer, and a protective sheet disposed on the reverse side of the adhesive layer from the base layer, the skin layer having a haze change of 50% or less through a test conducted for 3,000 hours with a sunshine carbon arc weatherometer under the conditions of an irradiance of 78.5 W/m2, with surface spraying, a black-panel temperature of 63±3°C, and a humidity of 50±5% RH; and a method for producing said protective film for exterior vehicular trims.
