The present invention aims to provide an adhesive tape capable of exhibiting excellent adhesion to rough surfaces. The present invention also aims to provide a method for fixing an electronic device component or an in-vehicle device component using the adhesive tape and a method for producing an electronic device or an in-vehicle device. Provided is an adhesive tape including an adhesive layer containing an acrylic copolymer, the acrylic copolymer containing 30% by weight or more of a structural unit derived from n-heptyl (meth)acrylate and 0.01% by weight or more and 30% by weight or less of a structural unit derived from 1-methylheptyl (meth)acrylate.

An adhesive composition includes a resin, a crosslinking agent, and a light absorber. The light absorber includes at least one selected from the group consisting of a benzophenone-based compound, a cyanoacrylate-based compound having a ring structure, a benzotriazole-based compound, and a sterically hindered amine compound having a ring structure.

A process for preparing an acrylic emulsion resin is provided by introducing specific monomers at a certain time during an emulsion polymerization process, dispersion stability and adhesion properties of the acrylic emulsion resin are improved, thereby providing an aqueous acrylic pressure-sensitive adhesive that not only has excellent initial adhesion but also has low viscosity and improved processability, and high adhesion holding power.

Useful articles, such as coatings, adhesives, printed graphics, 3D printed articles and molded articles are prepared by curing compositions containing one or more salts of ethylenically unsaturated carboxylic acids comprising six or more carbon atoms, one or more multifunctional (meth)acrylate oligomers and one or more mono(meth)acrylate esters of alcohols which, when polymerized as homopolymers, have glass transition temperatures of at least 50° C.
