HEAT DE-BONDABLE ADHESIVE ARTICLES

摘要

Heat de-bondable adhesive articles include a heat-shrinkable optical substrate with optically clear adhesive disposed on the two major surfaces of the heat-shrinkable substrate. Optical articles can be prepared by disposing the heat de-bondable adhesive articles between two optical substrates. Other optical articles can be prepared by disposing an optically clear adhesive layer and a heat-shrinkable optical substrate on an optical substrate.

1. An adhesive article comprising:
a first layer of optically clear adhesive with a first major surface and a second major surface; 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; and a second layer of optically clear 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, 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 either 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.
