An article may include a biodata page defining a perimeter including an edge and a hinge layer attached to at least a portion of the biodata page. The hinge layer comprises a cross-linked polyurethane. In some examples, the hinge layer may include a cross-linked thermoset polyurethane.

A transaction card includes a first full thickness portion and a second, reduced thickness portion. Each of the first and second portions includes a top surface and an opposing bottom surface spaced from the top surface by a thickness of the card. The first, full thickness portion includes an extent of the card that remains exposed when the card is inserted into a pocket of a card-carrying case, and a feature deviating from a flat region along at least one of the top surface and the opposing bottom surface of the card. The feature is configured for tactile engagement to facilitate removal of the card from the pocket.

Display regions each include a plurality of reflection surfaces. The reflection surfaces are arranged at an average pitch of 1 m and 300 m inclusive in a direction in which the reflection surfaces are arranged. The display regions of each display region group include display regions that differ from one another in the normal direction of the reflection surfaces. Each display region group is configured to form, in the associated observation direction, an image that is unique to the display region group and composed of the image elements formed by the display regions of the display region group.

The invention relates to a process for protecting variable inscriptions of a document in which: a transparent film is bonded to a face of said document with a view to protecting variable inscriptions of said document, by at least one adhesive layer comprising at least one thermoplastic polymer having a glass transition temperature between 40 C. and 110 C. and having a hydroxyl value between 3 mg of KOH/g and 60 mg of KOH/g and/or an acid value between 2 mg of KOH/g and 150 mg of KOH/g, said adhesive layer comprises a crosslinking agent having at least 2.8 functions selected from the group formed of isocyanates, carbodiimides, aziridines and alkoxysilanes, during the bonding, a crosslinking of said adhesive layer is carried out. The invention also relates to a protective device and to a document.

A method for producing a printed material includes forming a color image having an image area ratio of 20% or less on a peripheral edge portion of a recording medium by using a coloring material; providing pressure-induced phase transition particles to a region of the recording medium, the region including the peripheral edge portion; bonding the color image and the pressure-induced phase transition particles onto the recording medium; and folding the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and pressure-bonding the folded recording medium, or pressure-bonding the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and another recording medium placed on top of each other. The pressure-induced phase transition particles contain a styrene resin and a (meth)acrylic acid ester resin, the styrene resin contains styrene and a vinyl monomer other than styrene as polymerization components, the (meth)acrylic acid ester resin contains at least two (meth)acrylic acid esters as polymerization components, and a mass ratio of the (meth)acrylic acid esters is 90 mass % or more of a total of all polymerization components of the (meth)acrylic acid ester resin. The pressure-induced phase transition particles have at least two glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature among the glass transition temperatures of the pressure-induced phase transition particles is 30? C. or more.

A security element for documents of value or the like, has a substrate which has been coated with a heat-sealing adhesive that is non-tacky at room temperature and suitable for applying the security element to a substrate of a document of value. The heat-sealing adhesive contains a radiation-crosslinkable component and a reactive diluent.
