Problems solved by technology

Colored media are mainly printing, printing, and copying materials. Photoelectric technology is used to control the distribution of digital information into ink droplets and toner, and then transferred to blank flat media to form text images. However, there is a serious social problem of waste polluting the environment. problems, and the reproduced image resolution depends on the particle size of ink droplets, carbon powder and other coloring substances and the performance of the reproduction equipment; The cloth information recording unit converts the digital information into the distribution of pressure, temperature, electric field, etc. and directly records it in the unit of the corresponding area on the medium. record digital information
Existing microcapsule materials use dry technology to reproduce information, and there is no problem of waste and residues polluting the environment. However, pressure-sensitive microcapsule materials are limited by the particle size of the microcapsules and can only be recorded and reproduced in fields such as text copying. Low-resolution image information

Embodiment 1

[0026] The preparation of embodiment 1 dye precursor microcapsule A

[0027] Put 8g ODB-2, 5ga-methylnaphthalene, and 30g ETAC into the same beaker, stir, and heat in an automatic constant temperature electric heating mantle to dissolve ODB-2 in the high boiling point solvent α-methylnaphthalene and low boiling point solvent In the mixed solvent of ETAC, take it out and cool it to room temperature, ODB-2 cannot be precipitated; put 20ml of D-110 into it, stir to get the oil phase mixture.

[0028] Measure 135ml of PVA-224 aqueous solution with a concentration of 3% and put it into a shear tank, add 20ml of surfactant, and the water phase is ready

[0029] The water phase was sheared at a high speed by a high-speed hardening shear at a speed of 13,000 rpm, and then the oil phase was added to the water phase, emulsified and dispersed for 10 minutes to obtain an oil-in-water emulsion. Add 300 ml of deionized water and 8 grams of tetraethylenepentamine to the oil emulsion dispers...

Abstract

A novel non-silver-salt information recording material is formed through a thermosensitive microcapsule information recording technology which combines a thermosensitive technology and a microcapsuletechnology and has the characteristics of rapid image development, high resolution ratio, environmental friendliness and the like. The thermal image development characteristic is the most important characteristic of the thermosensitive microcapsule material, and the image density situation of the thermosensitive microcapsule material after thermal image development can directly reflect the imagingquality of the thermosensitive microcapsule material.

Description

technical field [0001] The invention relates to a heat-sensitive medical image recording material. technical background [0002] Information recording and reproduction materials are an indispensable tool in human study, life and work. With the rapid development of information technology, information in the form of pictures, text, etc. needs to be recorded, preserved or reproduced, and people put forward higher requirements for information recording and reproduction materials. [0003] Traditional information recording uses silver salt information recording material as the main carrier. Silver salt information recording material is an efficient information recording and storage material. It integrates information receiving, storage and reproduction, and has high image resolution. It is also relatively simple, so it has a wide range of applications in the fields of military, science and technology, medical treatment and daily life. However, the silver salt information record...
