A debondable article including a polymeric film containing a crosslinker having a photodegradable linkage is further provided, as well as a method of debonding the article. Foam compositions are also provided, including foamed matrices including the reaction products of the compositions. Further, articles and foam adhesives are provided including a substrate and a composition or foam composition disposed on the substrate. A method is additionally provided, including dispensing a composition onto a substrate; subjecting the composition to light radiation having a wavelength band of 50 nanometers or less to initiate polymerization of the composition; and subjecting the composition to light and/or heat radiation, wherein the light radiation has at least one wavelength that is outside the wavelength band of the light radiation of step b) to initiate foaming of the composition. A crosslinker is further provided, including a photodegradable linkage.

Abstract: Acrylic pressure-sensitive adhesive (“PSA”) compositions crosslinked with a small-molecule crosslinker containing a single, thermally reversible moiety represented by the structure (I) (Formula I)). wherein each R1 is independently —H or —CH3, each X is independently C2-C6 alkyl, and each R2 is independently a C1-C6 alkyl group or an aromatic group. Under high temperature conditions the crosslinks may be broken, thus allowing for good coating and dispensing of the PSA. Upon cooling, the crosslinks reform to create a gelled PSA network without need of additional post-processing curing steps.

Abstract: Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.
