Abstract
An adhesive composition is disclosed that comprises acrylic adhesive particles having an average diameter of 10 to 100 micrometers obtained by suspension polymerization of an acrylic monomer mixture which comprises a branched C 14-22 alkyl group containing (meth)acrylate and a polar monomer. The adhesive composition may be applied to an adhesive dressing or patch. The adhesive has excellent water vapor permeability, excellent adhesion to skin with low skin irritation when applied, less adhesive residue after peeling, and less keratin damage. The adhesive does not cause wetness or peeling from sweat while being worn.
