Abstract: An adhesive blend includes a pressure sensitive adhesive and non-tacky microspheres that function as a detackifier. The non-tacky microspheres are solid, elastomeric, non-crushable, and solvent insoluble. The non-tacky microspheres are a reaction product of at alkyl (meth)acrylate monomers having from 1 to 14 carbon atoms, multifunctional (meth)acrylate and or multifunctional vinyl crosslinker, initiator, and polymeric stabilizer. The blend can be coated onto a sheet to form a pad, such as an easel pad.
