Title:
POLYPROPYLENE RESIN-BASED VOID-CONTAINING FILM
Document Type and Number:
Japanese Patent JP2009051886
Kind Code:
A
Abstract:
To provide a polypropylene resin-based void-containing film that normally reflects diffusely a coherent reflected light emitted by a coherent glossy color pigment, does not exhibit a coherent reflecting gloss, exhibits a coherent reflection effect only in a region in which voids are lost by heating and pressure and has a potentially coherent reflecting gloss.
The polypropylene resin-based void-containing film comprises a polyolefin-based resin, a void developer and a coherent glossy color pigment and has a void developer content in the film of 8 wt.% and 18 wt.%. The coherent glossy color pigment is metal oxide coated mica in the polypropylene resin-based void-containing film.
