Provided is a novel transparent adhesive material having low relative permittivity as well as excellent adhesive characteristics, whereby an olefinic polymer resin layer and an acrylic polymer adhesive layer can be suitably integrated. Suggested is a transparent adhesive material provided with an outermost surface layer containing an acrylic polymer (B) and a photocrosslinking initiator, and an intermediate layer containing an olefinic polymer (A), a crosslinking agent, and a photocrosslinking initiator, in which the intermediate layer contains a (meth)acrylate monomer as the crosslinking agent.

The present application relates to an adhesive composition comprising a polypropylene resin, a tackifying resin and a plasticizer resin having a superior balance of properties in regard of Brookfield viscosity and maximum probe tack. It further relates to an article comprising the adhesive composition and to a process for producing said article. The application also relates to the use of the adhesive composition in the preparation of an article.
