Provided is a multilayer body having good print readability and removability. A multilayer body (1) is for a laser marking label and includes a first layer (10) allowing laser light to pass through, a second layer (20) developing a color by laser light, and a third layer (30) having adhesiveness, which are stacked in this order. The second layer (20) consists of a resin composition containing an acrylic-based copolymer, an isocyanate-based crosslinking agent, a color development pigment, and a white pigment. The isocyanate-based crosslinking agent is selected from (i) an aromatic-aliphatic isocyanate-based crosslinking agent or (ii) a mixture of an aliphatic or alicyclic isocyanate-based crosslinking agent and an aromatic isocyanate-based crosslinking agent. A contained amount of the isocyanate-based crosslinking agent is 5-40 parts by mass with respect to 100 parts by mass of the acrylic-based copolymer. The second layer (20) is in contact with the first laver (10).

The present application relates to a method for manufacturing an indicator for food that can visually check the quality change in food in a package state, an indicator for food manufactured therefrom, and a method for checking the storage status of food using the same. The manufacturing method of an indicator for food of the present application includes bonding a first film, on which an indicator layer including a pH-sensitive indicator is formed on one surface thereof, and a second film, on which an adhesive layer is formed on one surface thereof, so that the indicator layer of the first film and the adhesive layer of the second film can face each other.

The present invention relates to a smart and secure label stock with security features. The present invention relates to a label stock produced from a substrate utilizing adhesive and liner materials and having a plurality of security features on the rear side of the substrate made using specialized inks and various authentication features for different applications.

A method for producing a label for affixing in a vehicle. The method includes printing of a substrate layer to yield a basic label form; production of an adhesive film with a first adhesive layer; and sticking the adhesive film to the basic label form using a second adhesive layer to produce the label. Also described is a label kit including a basic label form with a printed substrate layer and an adhesive film, wherein the adhesive film is configured to be stuck to a printed side of the substrate layer of the basic label form.

A label has a topcoat layer and a sacrificial layer. The topcoat layer has a first color having a first L-value and the sacrificial layer has a second color having a second L-value. The topcoat layer comprises at least one reflective pigment and a polymeric binder and the sacrificial layer comprises at least one infrared (IR) absorbing material and a polymeric binder. The first L-value is greater than the second L-value, and the total amount of the at least one reflective pigment is from 40 wt % to 80 wt %, based on the weight of the topcoat layer.

A shipping label is operable to be applied to a package and includes a single label ply. The single label ply presents longitudinally spaced ends, opposite top and bottom faces extending between the ends, and a generally transverse fold line of weakness spaced between the ends. The label ply is foldable about the fold line to define upper and lower label sections, with the upper label section overlying the lower label section when the label ply is folded, and the top face of the upper label section being operable to receive package address indicia thereon. The upper label section includes a separation line of weakness defining a border portion and a separable central portion. The upper label section includes adhesive applied to the bottom face along at least part of the border portion. The lower label section includes a dividing line of weakness defining a connecting portion and an end portion, with the connecting portion extending between the fold line and dividing line. The end portion is at least in part positioned underneath the central portion of the upper label section when the label ply is folded, with separation of the central portion from the border portion providing access to the end portion thereunder.

A label for a package that includes a base layer and a top layer attached to the base layer is disclosed. The base layer includes a central surface adapted to receive written markings. The top layer covers at least part of the base layer and includes perforations such that a detachable part of the top layer has a perimeter at least partially defined by the perforations. The detachable part includes a front surface and a back surface that faces the base layer while the perforations remain intact. The front and back surfaces of the top layer are adapted to receive written markings. And, the top layer is opaque such that while the perforations remain intact, any written markings on the back surface of the detachable part or on the central surface of the base layer are not visible from a vantage point outside of the label.

A method for ablating a label having a topcoat layer and a sacrificial layer includes irradiating at least one target region on the topcoat layer with a laser beam and further includes removing the topcoat layer and at least a portion of the sacrificial layer in the at least one target region.

An adhesive-free laminate and a process for producing such a laminate are described herein. The process includes printing an ink on the surface of a first film, exposure of the printed film to UV radiation such that the ink is at least partially cured, attaching the first film to a second film such that the ink is between the first and second film, and exposing the combination of the first film, the ink and the second film to a second UV radiation. It has been found that this process can produce a unique laminate, without the presence of an adhesive.

A multi-purpose sticker for decorating and sealing an envelope and also for attaching the sealed envelope to a package, such as a gift. The multi-purpose sticker generally includes a double-sided adhesive layer hidden below a decorative covering. With the decorative cover in place, one side of the double-sided adhesive of the sticker can be used to seal an envelope, and the sticker serves as a decorative sticker. If desired, the decorative cover can be peeled off to expose an adhesive in order to affix the sealed envelope to a package.
