Abstract

The invention relates to the technical field of thermosensitive labels, in particular to a bottom blue-developing thermosensitive label and a preparation method thereof. The bottom blue-developing thermosensitive label comprises a bottom layer and a dye layer which are sequentially arranged from bottom to top, wherein the bottom layer is carbon-source-free paper, and the dye layer is made of developing dye; the color development dye comprises the following raw materials in parts by weight: 25-30 parts of a colorless buffer toner, 10-15 parts of a color developing agent, 3-8 parts of a flattingagent A, 3-5 parts of a defoamer A, 2.5-3.0 parts of an aqueous polytetrafluoroethylene modified wax dispersion, and 30-35 parts of a solvent A. The dye layer of the bottom blue-developing thermosensitive label can change the color developing of the printed characters in a printing state of a thermosensitive printer, can improve the withered monotonous sense of only single black characters at present and can improve the color development effect. The preparation method of the bottom blue-developing thermosensitive label has the advantages of the simple operation, the easy control, the high production efficiency and the stable quality, and can be used for mass production.

Description

technical field [0001] The invention relates to the technical field of heat-sensitive labels, in particular to a heat-sensitive label with blue bottom layer and a preparation method thereof. Background technique [0002] Express electronic waybills have been fully popularized in China, with 60 million electronic waybills being used every day. The annual usage on "Double 11" exceeds 200 million per day. However, the text on the heat-sensitive label used in the existing express delivery is basically black, the visual effect is relatively monotonous and boring, and during the express delivery process, it is easily affected by moisture, temperature, scratches, etc., resulting in blurred writing. Affect the transportation and delivery of express delivery. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a bottom-layer blue thermal label, the dye layer of the bottom blu...
