The present invention also relates to an organic electroluminescent device prepared using said film.

The invention relates to a heat-sensitive recording material, comprising: a support material in sheet form, a color layer on one side of the support material in sheet form; and a heat-sensitive layer on the color layer, so that the color layer is at least partially covered, the heat-sensitive layer being such that it becomes translucent by local application of heat, so that the underlying color layer becomes visible; and a protective layer on the heat-sensitive layer, the protective layer containing less than 5% by weight of pigments. The invention also relates to its use as a receipt roll, adhesive label (roll), ticket (roll) or as printer paper for mechanical printers or pens.

The present invention is to provide a thermal transfer sheet which is able to prevent a heat resistant slipping layer from transferring to a guide roller, etc., and which is able to prevent wrinkles when printing. Disclosed is a thermal transfer sheet including a substrate sheet, a thermal transfer layer disposed on one side of the substrate sheet, and a heat resistant slipping layer disposed on the other side of the substrate sheet via a primer layer, wherein the primer layer contains a cured product of a resin composition containing one or more kinds of resins selected from a urethane resin and a polyester resin and a compound having a functional group selected from an epoxy group, a silanol group and a hydrolyzable silyl group.

An elongated printing tape includes a heat-sensitive layer, a first protective layer, a second protective layer, and a first adhesive layer. The heat-sensitive layer produce color at temperatures within a prescribed range. The first protective layer is provided on the heat-sensitive layer. The second protective layer is provided on the side of the heat-sensitive layer opposite the first protective layer. The second protective layer contains at least one resin selected from a group consisting of fluorine-based resins, silicone-based resins, olefin-based resins, polyester-based resins, epoxy/polyester-based resins, and silicon-based resins. The first adhesive layer is provided on the side of the second protective layer opposite the heat-sensitive layer. The first adhesive layer contains at least one adhesive selected from a group consisting of (a) emulsion-type adhesive compounded with tackifying resin and containing acrylic polymer and rubber-based adhesive, (b) silicone-based adhesive, and (c) rubber-based adhesive.

A heat-sealable heat-sensitive film of the present invention includes a substrate and a heat-sensitive recording layer and is thermally bonded to a material to be sealed, in which the heat-sensitive recording layer is not provided in a portion of the substrate that is thermally bonded to the material to be sealed, and the heat-sensitive recording layer is provided in a portion of the substrate other than the portion of the substrate that is thermally bonded to the material to be sealed.

The purpose of the present invention is to provide a thermosensitive recording medium with an increased gloss in the blank and printed portions, excellent color developing sensitivity and excellent printing run-ability, particularly excellent printing run-ability at high-speed printing. Provided is a thermosensitive recording medium having a thermosensitive recording layer comprising a colorless or pale colored basic leuco dye and an electron accepting color developing agent, an intermediate layer and a gloss layer as an outermost layer in this order on a substrate, wherein the intermediate layer is formed by containing a carboxyl group-containing resin and the gloss layer is formed by containing a long chain alkyl group-containing resin and an emulsion type silicone copolymer resin. The long chain alkyl group-containing resin is preferably an acrylic resin containing long-chain alkyl group(s) and the silicone copolymer resin is preferably a silicone-acryl copolymer resin and/or a silicone-urethane copolymer resin.

There is provided a heat-sensitive transfer recording medium which is able to better suppress the occurrence of abnormal transfer during high-speed printing using a high-speed printer of sublimation transfer type and is able to improve transfer sensitivity in high-speed printing. The heat-sensitive transfer recording medium includes a base (10), a heat-resistant lubricating layer (20) formed on one surface of the base (10), an underlying layer (30) formed on the other surface of the base (10), and a dye layer (40) formed on a surface of the underlying layer (30), which is on the other side of a surface facing the base (10). In the heat-sensitive transfer recording medium, the underlying layer (30) has a major component that is a copolymer of polyester having a sulfonic group on a side chain and acrylic having at least one of a glycidyl group and a carboxyl group.

A thermosensitive recording medium for a linerless label is provided. The thermosensitive recording medium includes a support, a thermosensitive recording layer, a protective layer, and a release layer. The release layer includes at least one selected from the group consisting of epichlorohydrin, polyamide epichlorohydrin, an oxazoline derivative, hydrazine, and a hydrazide derivative. The thermosensitive recording layer, the protective layer, and the release layer are disposed on one side of the support.

Plasmonic color printing by fabricating a Fabry-Prot (F-P) resonant structure on a substrate. The F-P resonant structure includes a reflective layer, a dielectric spacer layer overlying the reflective layer, and a random metal film (RMF) layer that overlies the dielectric spacer layer and has a nanostructure. The F-P resonant structure is photomodified using a laser, which induces changes in the nanostructure of the RMF layer. These changes are tailored to produce desired changes in the light-scattering and reflective properties of the RMF layer. As a result, by tailoring the photomodifications and the changes it produces, the color-generated by illumination filtered through and reflected from the F-P resonant structure can be tailored to a desired hue.
