The present invention has the following features. The present invention relates to a flammable flame-proof material provided with a metal material, comprising a metal material and a non-flame-proof-treated thin film sheet on the top of the metal material, wherein an adhesive agent is between the metal material and the non-flame-proof-treated thin film sheet, and relates to an attachment structure for attaching a metal plate with a flammable thin-film construction interior material.

Provided is photo-sintering nano ink. The photo-sintering nano ink includes a photo-sintering precursor including a conductive nano particle and an oxide film surrounding the conductive nano particle, polymer binder resin, and an adhesive.

Provided is a double-sided pressure-sensitive adhesive tape, which is excellent in initial pressure-sensitive adhesive property to an adherend, is sufficiently elongated, hardly breaks even when sufficiently elongated, can be smoothly pulled and removed from the adherend under an elongated state, and is excellent in reworking properties. The double-sided pressure-sensitive adhesive tape in an embodiment of the present invention includes, in this order: a pressure-sensitive adhesive layer (B1); a base material layer (A); and a pressure-sensitive adhesive layer (B2), wherein the pressure-sensitive adhesive layer (B1) and the pressure-sensitive adhesive layer (B2) each contain at least one kind selected from the group consisting of: an acrylic pressure-sensitive adhesive; and a rubber-based pressure-sensitive adhesive, and the acrylic pressure-sensitive adhesive contains a filler, wherein the base material layer (A) contains, as a resin component, at least one kind selected from the group consisting of: polyolefin; thermoplastic polyurethane; and a styrene-based polymer.

The invention concerns a linerless self-adhesive material obtained starting from a self-adhesive material with a liner, by means of a process that comprises the delamination of the liner from a self-adhesive layer, activation of the liner or self-adhesive layer, transferral of the liner over the self-adhesive layer and re-lamination of the two components so as to produce the linerless self-adhesive material. The liner or the self-adhesive layer is coated with a thermo-adhesive that allows for permanent lamination of the liner located on the self-adhesive layer.
