Claim Text:
1. An acrylic emulsion pressure-sensitive adhesive (PSA) composition comprising latex particles in which at least three anionic emulsifiers cover polymer particulates comprising: a (meth)acrylic acid ester monomer having a C at least one monomer selected from the group consisting of a monomer having an allyl ester group, a vinyl ester group, an unsaturated ester group, or a mixture thereof, a cyano group containing monomer, an amine group containing monomer, and a styrenic monomer having a vinyl group, as an auxiliary monomer; a monomer having a carboxyl group and/or a hydroxyl group as a functional monomer; and a crosslinking agent, wherein the latex particles have a nanometer scale average particle diameter and monomodal particle size distribution.
