Abstract

The invention provides heat-sensitive paper and a preparation method thereof. The heat-sensitive paper comprises a base paper layer, and a precoating layer and a chromophoric layer which are one-step coated on the base paper layer. According to the invention, a plurality of high-insulation materials are used in the chromophoric layer, so the vast majority of limited pringting energy is remained in the chromophoric layer under a high-speed condition and is utilized by heat-sensitive chromophore; thus, adaptive performance of high-speed printing of the heat-sensitive paper is improved. During high-speed printing, the heat-sensitive paper in the invention remains excellent chromophoric performance and image-text clarity.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for improving thermal paper suitability for high-speed printing. Background technique [0002] With the further improvement of the working and living speed of human beings, higher requirements are put forward for the speed of thermal printers, such as increasing the printing speed of cashiers in supermarkets or the printing speed of ATMs in banks to reduce the time for customers to wait in line. In order to meet this demand, various thermal printer manufacturers are making gradual improvements, which also put forward higher technical requirements for thermal paper. [0003] With the higher printing speed, the energy received by the thermal paper decreases, which results in incomplete color development of the thermal paper and poor printing effect. Contents of the invention [0004] In order to ensure the color development performance of heat-sensitive paper during...
