Abstract
Articles comprising a substrate, preferably a retroreflective sheeting, having a coating of a pressure-sensitive adhesive composition, and articles wherein the adhesive adheres the substrate to a highly monomericly plasticized PVC component, preferably a PVC coated fabric. The adhesive comprises a crosslinked copolymer of a first monofunctional acrylate ester of a non-tertiary alcohol having as a homopolymer a glass transition temperature of less than -25.degree. C., a nitrogen containing moderately basic monomer copolymerizable therewith selected from the group consisting of N,N-dialkyl substituted amides, an optional copolymerizable acidic monomer, an optional second monofunctional acrylate ester of a non-tertiary alcohol having as a homopolymer a glass transition temperature -25.degree. C. or greater, and a crosslinking agent. A method of bonding a highly monomericly plasticized PVC component to a substrate, preferably a retroreflective sheeting, using the adhesive.
