NEAR INFRARED ABSORPTIVE LAMINATE - NIPPON CATALYTIC CHEM IND

Title:

NEAR INFRARED ABSORPTIVE LAMINATE

Document Type and Number:

Japanese Patent JP2002301785

Kind Code:

A

Abstract:

To provide a near infrared adsorptive laminate which displays superior weatherability under an inhibitive effect upon the deterioration of a near infrared absorptive pigment.

This near infrared absorptive laminate is of such a structure that a transparent plastic film base material is formed on both sides of a layer containing the near infrared absorptive pigment having a maximum absorptive wavelength in the range of 780 to 1,200 nm. The transparent base material is a material with a moisture permeability of 1,000 g/m2.24 hrs or less. The near infrared absorptive laminate shows a near infrared absorbing power residual rate of 70% or higher after 192 hours of a continuous irradiation test by an accelerated weatherability test using an ultraviolet autofadeometer.
