Abstract
Heat de-bondable optical articles include two optical substrates and a heat de-bondable adhesive article disposed between them. The adhesive article includes a heat-shrinkable substrate and an optically clear adhesive proximate to the heat-shrinkable substrate. Optical articles can be prepared by disposing the heat-shrinkable substrate and the optically clear adhesive between two optical substrates. The optically clear adhesive covers a majority of the surface area of the optical substrates, and the heat-shrinkable substrate is located near the edge of the optical substrates.
