Abstract: Chemical compositions such as adhesive, sealing or coating compositions containing one or more microencapsulated ingredients are activated by directly contacting an ultrasonic device (2) to the composition (8) and sonicating the composition to rupture the microcapsules. The method may be carried out in a sonication chamber (1) in which the ultrasonic device (2) is immersed in the composition (8) and from which the composition flows before it sets. Alternatively the ultrasonic energy may be applied to the composition in situ.

Abstract: A method for imaging vapor deposited photoresists of cyanoacrylates or related anionically polymerizable monomers without the use of solvent development. This method consists of treating the substrate with a compound which releases acid when exposed to high-energy radiation. In certain cases when the surface of the substrate is slightly acidic or neutral, it is necessary to activate the surface with a basic liquid or vapor which must be chosen so as not to react with the radiation-sensitive acid precursor. The substrate is exposed to actinic or ionizing radiation through a mask or to steered high-energy beams. Finally, the substrate is exposed to a vapor of cyanoacrylate monomer which condenses and polymerizes on the unirradiated regions forming a relief image.

Abstract: A method for applying a polymeric resist coating of very high molecular weight to a suitable substrate without the necessity of elaborate purification steps and for ensuring adequate coverage of raised regions in three-dimensionally patterned substrates. The method comprises exposing the substrate to be coated to the vapor of an anionically polymerizable monomer of the formula:CHR.dbd.CXYwhere X and Y are strong electron withdrawing groups and R si H or, provided that X and Y are both --CN, C.sub.1 -C.sub.4 alkyl for sufficient time to deposit a polymerizable coating thereon. Particularly preferred monomers are 2-cyanoacrylate esters. The monomer condenses and polymerizes on the surface of the substrate to give a highly uniform high molecular weight polymeric coating which is useful as a resist coating in lithographic processes employing plasma or acid etch techniques.
