Multi-stage irradiation process, for the production of a composition based on acrylic, adhesive, pressure-sensitive adhesive tape, and, multi-stage irradiation process for the production of an acrylic-based pressure-sensitive adhesive tape

摘要

Disclosed is a novel, multi-stage irradiation process for the production of an acrylic-based adhesive or pressure-sensitive adhesive tape. The first irradiation step or stage employs electromagnetic radiation at a relatively low average intensity (i.e., 0.1 to 20 mW/cm2) and the subsequent step employs electromagnetic radiation at a relatively higher average intensity (i.e., greater than 20 mW/cm2.) Also disclosed are acrylic-based psa tape materials made by the novel process.
