Thermal recording media and void-containing polyolefin films for use therein

摘要

Thermal recording media each having as a support or a part thereof, a void-containing polyolefin film with a void volume of from 10 cc to smaller than 40 cc per 100 g of the film. The thermal recording media can attain the excellent advantages that they have high resolving power, they can give high-density and distinct images recorded even with very small printing energy, they have high delamination resistance, i.e., they are not easily delaminated by adhesive tape or others, and they have high opacifying power and high elasticity.
