The present invention relates to self-foaming hot melt adhesive compositions and methods of making and using the same. Self-foaming hot melt adhesive compositions are formed by admixing a dispersion concentrate including a chemical blowing agent and a compatible carrier (liquid or molten) with a molten base hot melt adhesive composition at a temperature below the decomposition temperature of the chemical blowing agent. The resolidified material is processed through a device that heats the material above the decomposition temperature of the chemical agent and cools it below such temperature before being dispensed. The device preferably includes sensors and a controller configured to prevent the material from accumulating an adverse thermal history during processing.

The present invention provides an aqueous pressure-sensitive adhesive composition that has excellent environmental friendliness, that needs no aging, that can be made into a one-pack type which is highly convenient, and that is capable of forming a pressure-sensitive adhesive layer which has no problem not only in initial pressure-sensitive adhesive force but also in pressure-sensitive adhesive force with time and which exhibits satisfactory re-releasability. The present invention is a re-releasable aqueous pressure-sensitive adhesive composition containing: as a main component, an emulsion [A] of a (meth) acrylic acid-based ester copolymer, the emulsion [A] containing a constituent unit that has a carboxy group or a hydroxy group and that reacts with a crosslinker; an emulsion [B] of a (meth) acrylic acid-based ester copolymer in an amount of 0.6 parts by mass or more in terms of a solid content based on 100 parts by mass of a solid content of the emulsion [A], the emulsion [B] functioning as a crosslinking assistant, being found to be unmeasurable in a particle diameter distribution analysis result at a pH=6.5 to 7.5, dissolving in water upon neutralization, and having a peculiar structure; and further, as a crosslinker [C], a hydrazide-based compound that is soluble or dispersible in water.
