Problems solved by technology

First of all, the film should not be stored for a long time. It will turn yellow and become moldy after being stored for a period of time in the film library. This will be unfavorable when it needs to be used as a diagnosis basis in the future, especially after the implementation of the medical malpractice handling method, it is even more important; Secondly, films are easily lost and damaged during the borrowing process, and once some materials are lost, the damage will be irreparable; third, it

Abstract

The invention discloses a medical laser color printing and imaging PET (Polyester) film and a preparation method thereof. The PET film comprises a laser printer powdered ink fixing layer, a bridging layer and a PET film, wherein the bridging layer is arranged between the powdered ink fixing layer and the PET film. The preparation method comprises steps as follows: preparing powdered ink fixing layer paint; carrying out corona treatment on the PET film; coating the PET film by a micro scale of aqueous synthetic emulsion or dispersion adhesive; then drying by hot air, so as to obtain the bridging layer; coating the powdered ink fixing layer paint on the bridging layer; and drying by the hot air, so as to obtain the PET film. The PET film is suitable for printing by a colored laser printer, can output a high-resolution image, and is suitable for being used for showing the details of a medical image. The preparation method is simple and efficient, and is suitable for being used for industrialization.

Description

Technical field [0001] The invention belongs to the technical field of PET films, and specifically relates to a medical laser color printing imaging PET film and a preparation method thereof. Background technique [0002] With the continuous development of clinical medicine, medical imaging technology is constantly updating and progressing, and it plays an increasingly important role. Seven major disciplines, such as X-ray diagnostics, CT diagnostics, ultrasound diagnostics, MR diagnostics, radiotherapy, interventional diagnostics, and nuclear medicine, play a very important role in basic medical research and clinical medical diagnosis. And has become an indispensable part of medical development. [0003] With the increasing development of medical imaging technology, the related image output system and imaging medium have also been continuously improved and improved. The imaging output system has evolved from a wet laser printer in the early 1990s to the most commonly used dry la...
