A two-component polyurethane composition containing at least 55% by weight of polybutadiene polyols based on the total amount of all polyols having an average molecular weight of at least 500 g/mol, and at least one latent hardener, where the ratio of the number of reactive groups in the latent hardener to the number of OH groups present is in the range from 0.02 to 0.4. The composition has a long open time, blister-free curing, a very low glass transition temperature, high elasticity and surprisingly high strength which is very constant over a wide temperature range. Furthermore, it has very good adhesion to metallic and nonmetallic substrates, causing barely any stress cracks on glassy thermoplastics.

A hot-melt adhesive for reinforcing a conductor terminal of a flexible flat cable, said hot-melt adhesive comprising at least one member selected from the group consisting of (P1) a hydrogenated product of a block copolymer of an aromatic vinyl compound and a conjugated diene compound, wherein the content of a structural unit derived from the aromatic vinyl compound is not more than 65 mass % relative to the sum of the content of the structural unit derived from the aromatic vinyl compound and the content of a structural unit derived from the conjugated diene compound, (P2) a hydrogenated product of a random copolymer of an aromatic vinyl compound and a conjugated diene compound, (P3) an acid-modified hydrogenated product of a copolymer of an aromatic vinyl compound and a conjugated diene compound, and (P4) an amine-modified hydrogenated product of a copolymer of an aromatic vinyl compound and a conjugated diene compound; and a reinforcing tape wherein a layer of the hot-melt adhesive is formed on one surface of an insulating film.

A brittle adhesive sheet includes a film base material, and an adhesive layer provided at a first surface side of the film base material, wherein the film base material has a film base material main body formed of a polystyrene-based resin and a print receptive layer provided at a second surface side, opposite to a side of the film base material where the adhesive layer is provided, and the print receptive layer includes a polyester-based resin or an acrylic-based resin.

The present invention relates to an adhesive compositions, facestocks and/or packaging labels containing same, where such compositions, facestocks and/or labels are designed to facilitate the recyclability of a plastic article formed from any suitable polymer or mixture of polymers (e.g., a polyethylene terephthalate (PET), high density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), or others of all plastic types), or even glass bottles. In another embodiment, the present invention relates to a method for removing an adhesive composition, facestock and/or packaging label containing same, from a plastic article that is to be recycled.

A thermal indicator, a thermal indicating composition (1), as well as two kinds of thermal indicating structures (11) are disclosed. The thermal indicator comprises an organic solid material (2) having a melting point higher than ambient temperature and a dye (3) which contacts the organic solid material (2) and is capable of being dissolved in the organic solid material (2) when the thermal indicator is heated to the melting point of the organic solid material (2). The thermal indicator, the thermal indicating composition (1), as well as these two kinds of thermal indicating structures (1) have simple structures and can be manufactured by a simple process. Furthermore, the existence of the dye (3) in its crystalline state offers significant resistance to UV radiation in outdoor applications.

Methods for applying high shrink wrap labels to a shaped article are disclosed. The leading edge of the label is bonded to the article. A seaming agent is applied, and the label is wrapped around the article. The seaming agent is then exposed to radiation to cure the seaming agent, and the label is then exposed to heat to cause heat-shrinking. The label is made of a film with at least one external layer that has a Hildebrand solubility parameter. The seaming agent includes a component having a Hildebrand solubility parameter that is within 2.2 MPa.sup.1/2 or within 4.4 calories.sup.1/2.Math.cm.sup.3/2 of the Hildebrand solubility parameter of the external layer of the film. The seaming agent also has a viscosity of at least 1 centipoise and less than 1000 centipoise when measured at any temperature between ambient temperature and 60 C. Articles including such affixed high shrink wrap labels are also disclosed.

Stiffening assemblies for use with labels or shelf label channels are described. The stiffening assemblies can be incorporated with one or more labels and provided so as to be conveniently used with shelf label channels or other point-of-sale displays.
