Abstract
A method of making an adhesive is provided, including obtaining an actinic radiation-polymerizable adhesive precursor composition disposed against a surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. The first portion and the second portion are adjacent to or overlapping with each other and the first irradiation dosage and the second irradiation dosage are not the same. The method forms an integral adhesive having a variable thickness in an axis normal to the surface of the actinic radiation-transparent substrate. Also, an adhesive article is provided, including a substrate having a major surface and an integral adhesive disposed on the major surface of the substrate.
