To provide a thermosensitive recording label, which contains a base, an under layer, a thermosensitive coloring layer, a barrier layer, a release layer, and an adhesive layer, where the under layer, the thermosensitive coloring layer, the barrier layer, and the release layer are disposed on one surface of the base in this order, and the adhesive layer is disposed on the other surface of the base, wherein the release layer contains a cured product of a heat curing silicone resin, and the barrier layer contains a cured product of a water-soluble resin with a crosslinking agent, and inorganic filler.

Thermosensitive recording label

Provided is a heat-sensitive adhesive agent that mainly comprises a thermoplastic resin and a heat-meltable substance capable of melting upon heating, and further comprises swellable mica.

Heat-sensitive adhesive agent and heat-sensitive adhesive sheet

A heat-sensitive pressure-sensitive adhesive which contains at least a thermoplastic resin and a thermofusible material, wherein the thermoplastic resin has a glass transition temperature of &#x2212;70&#xb0; C. to &#x2212;30&#xb0; C., and the thermofusible material comprises triphenylphosphine, and at least any one of tris(2,4-di-t-butylphenyl)phosphite and tetrakis[3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate]methane, or a heat-sensitive pressure-sensitive adhesive which contains at least a thermoplastic resin, a thermofusible material and a non-thermofusible material, wherein the thermofusible material contains triphenylphosphine.

Heat-sensitive pressure-sensitive adhesive and heat-sensitive adhesive material

A thermal transfer image receiving material including a substrate, an intermediate layer which includes hollow particles and a binder resin and which is formed overlying the substrate, and an image receiving layer which includes a resin and which is formed overlying the intermediate layer and on which an image is to be formed, wherein each of the hollow particles in the intermediate layer has a particle diameter not greater than about 35 &mgr;m.

Thermal transfer image receiving material and thermal transfer recording method using the receiving material

A sublimation thermal transfer recording material including a substrate and one or more ink layers formed on one side of the substrate and including at least a yellow sublimable dye, a magenta sublimable dye and a cyan sublimable dye to form at least a black color image on a receiving material, wherein the magenta and the cyan sublimable dye have better light resistance than the yellow sublimable dye.
