The manufacturing method of the Optical layer comprising the thermochromic layer having good optical characteristic controlling photonic evaporation and photonic sintering conditions

摘要

The present invention is a substrate; an optical laminate that is formed on the substrate and includes a thermochromic layer comprising vanadium oxide particles, an adhesive strength between the thermochromic layer and the substrate is 50 N/m or more, and the thermochromic layer is controlled to have a specific void area ratio sieve, and the laminate has excellent visible light transmittance and infrared transmittance.
