Claims44
A layered construction, comprising:
- a first layer comprising a first side and a second side;
- wherein the first layer, an adhesive layer, or a facestock layer,
- wherein the base layer is selected from the group consisting of a paper, polymeric film, fabric, metallic foil, and combinations thereof;
- and
- a functional layer applied on a portion of the first side of the first layer or the second side of the first layer;
- wherein the functional layer comprises a first side, a second side and a stimuli-responsive polymer;
- wherein the stimuli-responsive polymer is a polymer selected from the group consisting of a poly(alkyl aldehyde), poly(halogenated aldehyde), poly(olefin sulfone), poly(cyanoacrylate), poly(glyoxylate), poly(glyoxamide), poly(isocyanate), poly(quinone methide), poly(benzyl ether), poly(carboxy pyrrole), poly(dithiothreoitol), poly(benzyl carbamate), copolymers thereof, cyclic polymers thereof, and combinations thereof.
