Abstract: Pressure-sensitive adhesive compositions that contain polymer microspheres with an average particle size of 20 μm to 100 μm, the polymer microspheres synthesized using the disclosed suspension polymerization techniques and include at least three structural isomers of a secondary (meth)acrylate of Formula (I), where R1 and R2 are each independently H or a C1 to C10 saturated linear alkyl group, the sum of the number of carbons in R1 and R2 is 7 to 18, inclusive, and R3 is H or CH3. The disclosed pressure-sensitive adhesive compositions may be used in masking articles to provide holding power to, clean paint-lines on, low surface energy adhesion to, and excellent damage-free removal from painted surfaces.
