A security article includes a laser markable layer and a transparent outer layer or sheet having lenticular lenses on its outer surface, both provided, in this order, on an opaque core support, characterized in that the laser markable layer has a dry layer thickness of less than 50 &#x3bc;m. An improved contrast is obtained between interlaced images exposed into the security article of the invention.

Laser markable security articles and documents

A security laminate () including in order a transparent oriented polyester support (), a subbing layer () and an adhesive layer () which is coated on top of the subbing layer, wherein the binder of the adhesive layer is based on a mixture of a first and a second polymer in a weight ratio from 50/50 to 90/10, wherein the first polymer is a copolymer comprising vinyl acetate and at least 85 wt % of vinyl chloride based on the total weight of the first polymer; wherein the second polymer is a copolymer of styrene, butadiene and methylmethacrylate or a copolymer of vinyl butyral, vinyl acetate and vinyl alcohol; and wherein the binder of the subbing layer is based on a polyester-urethane copolymer.

PET-C based security laminates and documents

Disclosed is a smart information carrier containing a security element laminated with a transparent polymer foil having a melting point higher than 150&#xb0; C. and the security element is surrounded by an edge at least 1 mm wide in which the transparent polymer foil on each side of the security element are laminated to one another, the security element including an IC-module and a fibre-containing continuous support, wherein the support is security printed on at least the side of the support nearer to the IC-module and the IC-module is encapsulated with a transparent polymer or polymer mixture with a melting point up to 150&#xb0; C. wherein the transparent polymer or polymer mixtures also coats the side of the support nearer to the IC-module. Also disclosed is a method of preparing the smart information carrier.

Smart information carrier and production process therfor

According to the present invention there is provided a laminating element comprising a transparent support coated with a thermally non-reversible layer comprising an ethylene-acrylic acid copolymer, a first polyurethane polymer and a second polyurethane polymer, said layer having a pH of at least 10 and containing a metallic or an amphoteric cation.

Security document comprising a mixture of polyurethanes

According to the present invention there is provided an imaged element comprising an optical card and underneath a layer package comprising in the order given an optional image receiving layer, a prelayer, an interlayer and a transparent support, at least the optional image receiving layer or the prelayer comprising an image, characterized in that the interlayer contains a polyurethane and a cross-linking agent.
