Se describe un adhesivo sensible a la presión (PSA) que lava múltiples sustratos. El PSA está compuesto de al menos un monómero hidrófilo, al menos un monómero hidrófobo, al menos un neutralizador, al menos un surfactante y al menos un monómero hidrófilo especializado. También se describe una etiqueta con una capa de sustrato y una capa de PSA compuesta por al menos un monómero hidrófilo, al menos un monómero hidrófobo, al menos un neutralizador, al menos un surfactante y al menos un monómero hidrófilo especializado. Los monómeros hidrófilos especializados adecuados incluyen, pero no se limitan a, metacrilato de poli(etilenglicol) (PEGMA) sus y derivados, ácido 2-Acrilamido-2-metilproano sulfónico (AMPS) o sal AMPS-sodio, y sus derivados. A pressure sensitive adhesive (PSA) that washes off multiple substrates is disclosed. The PSA is comprised of at least one hydrophilic monomer, at least one hydrophobic monomer, at least one neutralizer, at least one surfactant, and at least one specialty hydrophilic monomer. A label with a substrate layer and a PSA layer composed of at least one hydrophilic monomer, at least one hydrophobic monomer, at least one neutralizer, at least one surfactant, and at least one specialty hydrophilic monomer is also disclosed. Suitable specialty hydrophilic monomers include, but are not limited to, poly(ethylene glycol) methacrylate (PEGMA) and its derivatives, 2-Acrylamido-2-methylproane sulfonic acid (AMPS) or AMPS-sodium salt, and its derivatives.
