A thermosensitive adhesive label comprising a laminate film of a first film layer and a second film layer, and a thermosensitive adhesive layer on the surface of the second film layer side of the laminate, wherein the Bekk smoothness of the surface of the first film layer side of the laminate film is from 2000 to 20000 seconds, the Bekk smoothness of the surface of the second film layer side of the laminate film is from 800 to 20000 seconds, the contact angle with water of the surface of the second film layer side of the laminate film is from 20 to 80°, and the surface strength of the thermosensitive adhesive layer is from 0.6 to 1.8 kg-cm.

In a first aspect, a multilayer film includes a holographic image layer, a first heat-shrinkable layer and a first adhesive layer between the holographic image layer and the first heat-shrinkable layer. In a second aspect, an authentication label includes a holographic image layer, a first heat-shrinkable layer, a first adhesive layer between the holographic image layer and the first heat-shrinkable layer, and a back adhesive layer.

Identification labels and their incorporation in rubber-based articles are described. The labels include RFID components and can be incorporated in tires. The labels can withstand the relatively harsh conditions associated with vulcanization.

The invention relates to a security element with manipulation detection, in particular a security label or a transferable element, having the following layers: a) a first layer which is an embossed support substrate or a support substrate (1) with a coating layer (6) that has an optically active structure (7) or a first liquid crystal layer, b) a second layer which is a liquid crystal layer (3), c) a light-absorbing layer (4), and d) an adhesive layer (5), wherein the adhesion between the layers a. and b. is lower than the adhesion between the layers b., c., and d., and the security element has a color shift effect.

The present invention relates to a thermosensitive label for monitoring the quality state of a thermosensitive article. The present invention also relates to a preparation method of the thermosensitive label and a thermosensitive article using the thermosensitive label. The thermosensitive label according to the present invention comprises two laminated layers which are physically-separated of a thermosensitive function layer and an adsorption-indication function layer. The two laminated layers are stored and transported separately, and combined together in use.

Methods of preparing extended content labels from prefabricated adhesive assemblies are described. The methods do not require delamination or relamination of the prefabricated adhesive assemblies. The prefabricated adhesive assemblies include a transparent face layer and an adhesive layer sensitive to radiant energy. Extended content printing is applied to a front face of the face layer. A mask is positioned between the adhesive layer and a radiant energy source. Radiant energy not blocked by the mask reduces the adhesion of irradiated portions of the adhesive layer. A floodcoat is applied over the extended content indicia, and front side indicia is applied over the floodcoat and is visible through the face layer and adhesive layer from a back side of the face layer.

Thin film labels, systems, and methods of making and using thereof are described. The thin film systems contain a label and a carrier film, where the label contains an overprint layer, indicia, and an adhesive layer. The carrier film may be coated on one or both sides with a release liner. The adhesive layer can be any suitable adhesive, such as a pressure sensitive adhesive, a fluid activatable adhesive, a heat activated adhesive, or a contact activated adhesive. The label is formed by printed or coating one or more layers of precursor material on the carrier film using standard printers. Suitable precursor materials include, but are not limited to epoxys, solvent cast films, polyurethane dispersions, such as acrylic-urethane hybrid polymer dispersions and polyester-polyurethane dispersions. After the overprint layer dries or is cured, the indicia are printed onto the overprint layer, then the adhesive is coated on top of the indicia.

A linerless thermal label web includes layers in the following order: a release layer, a thermal paper comprising a heat sensitive part, and an adhesive layer, wherein the adhesive layer includes an adhesive deadening varnish at longitudinal edge areas of the linerless thermal web so as to reduce the tackiness of the adhesive layer in the longitudinal edge areas. A thermal label can be produced from the label web and the label web can be used for variable information printing applications.

A label comprising a body having a first side for attaching to a container and a second side for displaying information, the first side includes a releasable adhesive for attaching the label to a container, wherein the releasable adhesive is treatable to cause the label to be separated from the container, and at least a part of the body is heat sensitive such that the label curls towards the first side to conceal part of the releasable adhesive when the label is heated to hinder the label separated from the container from re-attaching to the container.

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.
