20110237432 | Thermosensitive Recording Material - A heat-sensitive recording material includes a paper web with recycled fibers and a heat-sensitive recording layer includes color formers and color acceptors. The amount of recycled fiber contained in the paper web is at least 70 percent by weight, and the heat-sensitive recording layer has, as color acceptor, at least 33⅓ percent by weight of N-(p-toluenesulphonyl)-N′-3-(p-toluenesulphonyloxyphenyl)urea in relation to the total content of color acceptors in the heat-sensitive recording layer. | 09-29-2011 |
20130123101 | Heat-Sensitive Recording Material Having Authenticity Feature - A heat-sensitive recording material includes at least a paper substrate, a heat-sensitive recording layer arranged on the front side of the substrate and which has at least one dye precursor and at least one color acceptor, wherein dye precursor and color acceptor react with one another under the action of heat to form color, and an authenticating security feature. The authenticating security feature is a mark which is applied to the back side of the paper substrate and which is made of a tincture having at least one organic solvent. A barrier coating is arranged between the substrate and heat-sensitive recording layer and is suitable to protect the heat-sensitive recording layer against penetration of the tincture into the heat-sensitive recording layer from the back side. | 05-16-2013 |
20140274681 | Heat-Sensitive Recording Material with Barrier Coating - A heat-sensitive recording material includes at least a substrate, a heat-sensitive recording layer arranged on the front side of the substrate and has at least one color former and at least one color acceptor, wherein the color former and color acceptor react with one another under the action of heat to form color, a protective layer covering the heat-sensitive recording layer, a barrier coating which contains ethylene vinyl alcohol copolymer (EVOH) and suitable for protecting the heat-sensitive recording layer against penetration of chemicals causing uncontrolled desensitizing reactions and color reactions in the heat-sensitive recording layer, wherein the barrier coating is arranged between the substrate and the heat-sensitive recording layer, and a tincture, as authenticating security feature, introduced into the substrate and/or applied to at least one side of the substrate. | 09-18-2014 |
