摘要:
A pressure-sensitive adhesive sheet according to the present invention is a double-sided pressure-sensitive adhesive sheet having a plastic substrate and pressure-sensitive adhesive layers provided on each side thereof. The pressure-sensitive adhesive layers are formed from a water-dispersed pressure-sensitive adhesive composition having an acrylic polymer dispersed in an aqueous solvent. An anchor layer formed from an anchor composition containing polyester-polyurethane dissolved in an organic solvent is provided between at least a first side of the substrate and the pressure-sensitive adhesive layer.
摘要:
A joined body includes: an adherend; a primer layer provided on the adherend; and a pressure-sensitive adhesive layer provided on the primer layer. The primer layer contains, as an effective component, at least one of chlorinated polypropylene and chlorinated polyethylene and an amount of the effective component per unit area is 0.5 [mg/cm 2 ] or less. The surface of the adherend may be formed of at least one of polypropylene (PP), polyvinyl chloride (PVC), and ethylene-propylene-diene rubber (EPDM).
摘要:
A laminate comprising a substrate layer; a contact adhesive layer comprising a contact adhesive agent having at least one of chloroprene rubber or acrylic copolymers, as well as microspheres having an average particle size of 0.5 μm or greater in the contact adhesive layer, wherein the contact adhesive layer contains from 5 parts by mass to 500 parts by mass of the microspheres per 100 parts by mass of the contact adhesive agent, and the contact adhesive layer has a plurality of protruding portions because of the microspheres.
