An adhesive article is described comprising a foamed adhesive layer and a non-foamed adhesive layer. The adhesive of each adhesive layer comprises a tetrahydrofurfuryl (meth)acrylate copolymer; an epoxy resin; a polyether polyol; and optionally a hydroxy-functional film-forming polymer. The adhesive may be used in structural and semi-structural bonding applications and is designed to fail cohesively.

A laminated film exhibits a certain adhesive property to various adherends having shapes or different irregularity shapes. The laminated film includes a resin layer A on one surface of a substrate and a resin layer B on the other surface. The resin layer A has a ten-point average surface roughness Rz(a) of 1.5 μm or more and 5.0 μm or less and a storage elastic modulus G′ at 25° C. and 1 Hz of 3.0×10.sup.5 Pa or more.

The invention relates to a peel detection label that is a laminate including a support, a pattern layer formed in a part of the surface of the support, and a pressure-sensitive adhesive laminate having at least a low modulus layer (X), a high modulus layer (Y) and a pressure-sensitive adhesive layer (Z) in that order, in which the low modulus layer (X) has a surface in contact with the support and the pattern layer and a surface in contact with the high modulus layer (Y), and satisfies the following requirement (1):

Requirement (1): when the pressure-sensitive adhesive layer (Z) of the peel detection label is attached to an adherend and then the peel detection label is peeled off from the adherend, the maximum vertical tensile stress applied to an element of the low modulus layer (X) that is located closest to the support is 0.19 MPa or more when analyzed by a finite element method using Abaqus.

An adhesive tape includes a substrate [I] and an adhesive agent layer of a polyester adhesive agent provided on at least one of opposite surfaces of the substrate [I]. The substrate [I] is one selected from a polyolefin resin foam substrate, a urethane resin foam substrate, and an acrylic resin foam substrate. The polyester adhesive agent is made from a polyester adhesive agent composition [II] which contains a polyester resin (A) having a weight average molecular weight of 5,000 to 300,000, and having a structural unit derived from a polyol and a structural unit derived from a polyvalent carboxylic acid compound containing an aromatic structure-containing compound in a proportion of not greater than 80 mol %. The adhesive tape is excellent in adherence between a polyester adhesive agent layer and a polyolefin resin foam substrate, a urethane resin foam substrate, or an acrylic resin foam substrate.

A flexible protective film is provided and is used to protect a curved display. The flexible protective film includes a substrate layer (10) and a flexible layer (20) laminated on the substrate layer (10). The flexible layer (20) is formed after a liquid-phase flexible material is laminated on a surface of the substrate layer (10) through solidification. The flexible layer (20) of the flexible protective film is directly formed on the substrate layer (10) to reduce internal stress of the flexible protective film, thereby increasing an adhesive force of the flexible protective film.

A laminate for forming objects that include Sodium Polyacrylate includes an adhesive substrate and a layer of Sodium Polyacrylate powder. The adhesive substrate includes a first surface facing a first direction away from the substrate, a second surface facing a second direction away from the substrate, and a thickness defined by the distance between the first surface and the second surface. The Sodium Polyacrylate is adhered to at least one of the first and second surfaces.

The present invention relates to a transdermal therapeutic system for administration of an active ingredient and a process for the preparation thereof. The transdermal therapeutic system comprises an overtape with two adhesive layers.

A film including: a substrate; a first barrier layer on the substrate; a resin layer on the first barrier layer; wherein the resin layer includes a structured major surface and a plurality of features; a second barrier layer on the structured major surface of the first resin layer; and an adhesive layer on the second barrier layer, wherein the adhesive layer includes a structured major surface and a plurality of features.

A pre-laid polymer waterproof rolling material, which comprises a sheet-like polymer carrier, a hot-melt pressure-sensitive adhesive layer on the sheet-like polymer carrier, and an anti-sticking coating on the hot-melt pressure-sensitive adhesive layer; The anti-sticking coating comprises the following components: 100-160 parts by weight of water; 50-80 parts by weight of a polyurethane resin; 15-20 parts by weight of a pigment; 10-12 parts by weight of a filler; 0.3-1 part by weight of a cross-linking agent; 0.5-1 part by weight of an antioxidant; 1-2.5 parts by weight of an anti-ultraviolet agent; and 0.03-0.2 part by weight of a thickener. The anti-sticking coating in the present application uses water as a solvent, water is non-toxic and non-corrosive, thus there is no environmental pollution problem in the production process.

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.
