Further, the thickness of the base layer is 0.15-0.25mm, and the base layer is a poly terephthalic acid plastic layer.

Furthermore, the thickness of the absorption layer, the thickness of the imaging layer and the thickness of the protective layer are all 0.1-0.2mm, the imaging layer contains microcapsules of color developing agents and color formers, and the protective layer contains inorganic raw materials and lubricants.

Further, the thickness of the matting agent layer (5) is 3-8 μm, and the matting agent layer contains nano tin oxide antimony powder.

The utility model has the advantages that:

1. the medical laser dry film of the utility model has the poly-p-phthalic acid plastic with enough thickness as the film base and is sprayed with the even imaging layer, so that the characteristics of static resistance, translucency, wear resistance, crease resistance and extrusion resistance are enhanced, thereby avoiding the use defects of fading, fading and the like after strong light irradiation, and the film can store the information shown on the surface for a long time, and is suitable for the image output field of medical diagnosis;

2. the medical laser dry film of the utility model has much lower manufacturing cost than the traditional film, and reduces the patient's visit expense;

3. the medical laser dry film adopts a laser imaging mode, has low requirement on environment, high printing speed and rich contrast and layers, and is cleaned in image texture, thereby greatly adapting to the condition that large and medium hospitals have more diseases;

4. the utility model discloses a various drawbacks that wet-type film was brought by film processing and chemical liquid have been eliminated to medical laser dry-type film, make medical image formation of image simple, and the inspection efficiency of hospital has been improved in the convenience, has made things convenient for the disease.
