Heat de-bondable adhesive articles

An article comprising:

• a first optical substrate with a first major surface and a second major surface;
• a first layer of optically clear adhesive consisting of a pressure sensitive adhesive, a heat activated adhesive, or a gel adhesive with a first major surface and a second major surface, wherein the first major surface of the first layer of optically clear adhesive is disposed on the second major surface of the first optical substrate;
• a heat-shrinkable optical substrate with a first major surface and a second major surface, wherein the first major surface of the heat-shrinkable substrate is disposed on the second major surface of the first layer of optically clear adhesive;
• a second layer of optically clear adhesive consisting of a pressure sensitive adhesive, a heat activated adhesive, or a gel adhesive with a first major surface and second major surface, wherein the first major surface of the second layer of optically clear adhesive is disposed on the second major surface of the heat-shrinkable substrate;
• and
• a second optical substrate with a first major surface and a second major surface, wherein the first major surface of the second optical substrate is disposed on the second major surface of the second layer of optically clear adhesive;
• and wherein at least part of the heat-shrinkable substrate has a threshold shrink force of at least 100 grams per inch (3.85 N/dm), and the first adhesive layer and the second adhesive layer each has a Failure Force of from 0.1 to 85 grams per inch (0.039-3.3 N/dm), where the Failure Force is determined by measuring the 90° Peel Adhesion at room temperature or the 180° Peel Adhesion at 100° C. to a glass substrate of an article comprising either the first adhesive layer and the heat shrinkable substrate or the second adhesive layer and the heat shrinkable substrate, and wherein the optically clear adhesives have a visible light transmission of at least 90% and a haze of less than 5%, wherein the shrink force and the Failure Force cause de-bonding upon the application of energy consisting of heat, and wherein the first and second optical substrates comprise substrates that are optically clear to visible light, and comprise rigid plates or semi-rigid substrates with a thickness of 100 micrometers.
