Methods, systems, and compositions that make it possible to form high resolution, pressure sensitive adhesive patterns or films on a wide range of substrates. The compositions generally incorporate a curable, fluid composition (i.e., pressure sensitive adhesive precursor). When cured, a pressure sensitive adhesive is formed. Ink jet printing and subsequent curing allows pressure sensitive adhesive features to be formed with high resolution and tremendous flexibility in the patterns by which adhesive features may be formed. Preferred embodiments of the invention incorporate rheology modifying agents that can be used to promote favorable dot gain and other printing characteristics, the ability to build print thickness, and mechanical properties of resultant cured adhesives.

Electrolyte compositions in which a salt is disposed in a thiol-ene matrix. The compositions retain their shape under operating conditions and exhibit an ionic conductivity of at least 1.times.10.sup.-6 when measured in the absence of solvent at 25.degree. C.

Polymer electrolyte composition based upon thiol-ene chemistry

The invention provides novel acrylamide functional disubstituted acetyl aryl ketones and a process for their preparation in high yields uncontaminated by difunctional material. The invention further provides photocrosslinkable compositions comprising one or more ethylenically-unsaturated monomers and as photoinitiator the acrylamide functional disubstituted acetyl aryl ketone of the invention. The compositions are useful for the preparation of films and coatings, particularly pressure-sensitive adhesive coatings.
