A kind of inherently tacky, polymeric, organic, solvent-insoluble, solvent dispersible, elastomeric, pressure senstitive adhesive microsphere having hydrophilic polymeric or oilgomeric moieties which contains: 100wt% product of polymerization: (a) at least one radicalized polymerizable monomer of at least 30wt% selected from 2-vinyl caprioic ethylate, vinyl decylate, vinyl laurylate, vinyl pelargonate, vinyl caproiate, vinyl propinate, vinyl octylate, iso-octyl acrylate, 4-methy-2-amyl acrylate, 2-methabutyl acrylate, iso-decyl methacrylate, iso-nonyl acrylate, iso-decyl acrylate, iso-nonyl acrylate, iso-decyl methacrylate, and its mixtures, where the polymers prepared from these monomers must have Tg lower than -10 deg. C; (b) at least one polarized monomer of 0-30wt% that can be copolymerized with the monomer of component (a), where the polarized monomer is selected from acrylic acid, methacrylic acid, itaconic acid, butene acid, maleic acid, fumaric acid, sulfonic ethyl methacrylate, sodium methacylate, ac
