    Abstract: The present invention provides a mask adhesive that plastically deforms easily, no adhesive residue remains after peeling from the mask, ease of handling is excellent, and haze on a pellicle film is unlikely to be increased. A mask adhesive resolving this problem contains a thermoplastic elastomer (A) for which the temperature at which the loss tangent measured at a frequency of 1 Hz is at a maximum value is −20 to 30° C., a tackifier resin (B), and a process oil (C). The total of the proportion (% CP) of paraffin carbon and the proportion (% CN) of naphthene carbon in the process oil (C) is 50% or more. The temperature of the mask adhesive at which the loss tangent measured at a frequency of 1 Hz is at a maximum value is −10 to 30° C., and the sulfur content of the mask adhesive is 300 μg/g or less.

    Abstract: The invention relates to a composite article comprising: —an item (2) to be attached to a substrate; and —an adhesive tape (3) for attaching the item to the substrate, the adhesive tape having a substantially flat shape with a first main surface (6) facing the item, the first main surface extending in a cross section perpendicular to the first main surface from a first edge (8) to a second edge (9); —a lamination region (11) on the first surface, wherein the lamination region is the region where the adhesive tape is laminated to the item; and —wherein the lamination region is smaller than the first main surface. The invention also relates to a method of making a composite article.

    Abstract: The objective of the present invention is to provide a thermoplastic adhesive film capable of, in a thermobonding step of a laminated body of different materials used particularly in automobile members, electronic members, construction members, etc., such as a polypropylene resin material, a polyamide resin material, and a metal material such as aluminum or steel plates, preventing deformation of the resin material and peeling due to thermal history after molding. Provided as a solution is a thermoplastic adhesive film comprising a resin composition (D) which contains a thermoplastic olefin elastomer resin (A), an acid-modified polypropylene resin (B) and a nucleating agent (C).
