摘要:
A thermosensitive recording adhesive sheet capable of forming colored images thereon upon application of heat, comprising (a) a support material with print patterns on the front side or back side thereof, (b) a thermosensitive coloring layer formed on the support material, (c) an adhesive layer formed on the back side of the support material, opposite to the thermosensitive coloring layer, and (d) a disposable backing sheet which is attached to the adhesive layer and can be peeled off the adhesive layer when the thermosensitive recording adhesive label is used. When necessary, (e) a protective layer for protecting the thermosensitive coloring layer and for improving the thermal head matching properties of the thermosensitive coloring layer can be formed on the thermosensitive coloring layer. Further, (f) an undercoat layer which is interposed between the support material and the thermosensitive coloring layer and (g) a back coat layer which bears a print pattern and is formed on the back side of the support material, opposite to the undercoat layer, can also be formed.

A thermosensitive recording material which comprises a support, an intermediate layer including a foamed portion with minute voids, having a smoothness of 2,000 seconds or more in terms of Bekk's smoothness, and a thermosensitive coloring layer, successively formed on the support, and which layers show the compression strain of 20% or more when a pressure of 0.55 kg/cm.sup.2 is applied in accordance with the Japanese Industrial Standards (JIS) P-8118. This thermosensitive recording material shows the compression strain of 5% or more as a whole when a pressure of 0.55 kg/cm.sup.2 is applied in accordance with the JIS P-8118.
摘要:
A thermosensitive recording sheet comprises a support material; a thermosensitive coloring layer formed on the support material, comprising a colorless or light-colored leuco dye, and an acidic material which colors the leuco dye upon application of heat thereto; and a protective layer formed on the thermosensitive coloring layer, comprising a water-soluble polymeric binder and silica powder with an oil absorption of 150% or more and with a bulk density of 5 ml/g or more, which are measured in accordance with Japanese Industrial Standard K 5101. This thermosensitive recording sheet has high dynamic thermal coloring sensitivity, is capable of yielding sharp images with high image density at low energy consumption with good thermal head-matching properties, and is resistant to chemicals.
摘要:
A diazo-type thermosensitive recording material comprising a diazo-type thermosensitive coloring layer formed on a support material, the diazo-type thermosensitive coloring layer comprising a diazo compound, a coupler capable of forming an azo dye in the reaction between the diazo compound and the coupler, and a petroleum resin with a melting or softening point ranging from 50.degree. C. to 150.degree. C., and with the addition of auxiliary components for improving the properties of the thermosensitive recording material. By the use of such a petroleum resin in the thermosensitive coloring layer, the diazo compound and the coupler are separated from each other, and the coloring reaction between the two is prevented during storage, so that excellent preservation over a long period is attained, while when image formation is done by heat application, the coupling reaction between the diazo compound and the coupler is accelerated due to the low melting point of the petroleum resin present in the thermosensitive coloring layer, whereby efficient thermal response to thermal heads is attained.
