Problems solved by technology

Unlike the traditional silver salt photosensitive film, which undergoes a series of cumbersome processes such as developing, fixing, and washing in the darkroom, it will cause environmental pollution and waste water.
Unlike dry film, it is not necessary to avoid high temperature, keep away from radiation sources and light sources, and it is expensive and easy to lose information due to secondary exposure fogging

Abstract

The invention discloses an environment-friendly medical laser printing film which can effectively increase the color reducibility and weather resistance of laser printing images. A special laser printing ink absorbing layer is arranged on one surface of the PET (Polyethylene Elycol Terephthalate) transparent sheet or semitransparent sheet, and an anti-static layer is arranged on the other surface of the PET transparent sheet or semitransparent sheet; the special laser printing ink absorbing layer comprises the following components according to mass percent: 20%-30% of polyacrylic acid emulsion, 5%-10% of a pigment, 0.1-1.0% of a dispersing agent, 1%-5% of a dye-fixing agent and the balance of water. The environment-friendly medical laser printing film has good color reducibility and high saturation level and effectively increases output accuracy and efficiency and is suitable for various laser printers.

Description

technical field [0001] The present invention relates to the field of laser printing film, more specifically, relates to an environment-friendly laser printing film suitable for outputting images of various medical diagnosis and treatment results in medical diagnosis and treatment. Background technique [0002] Non-silver salt digital medical imaging printing film is the development direction of modern medical imaging system. Unlike the traditional silver salt photosensitive film, which undergoes a series of cumbersome processes such as developing, fixing, and washing in the darkroom, it will cause environmental pollution and waste water. Unlike dry film, it is not necessary to avoid high temperature, keep away from radiation sources and light sources, and it is expensive and prone to information loss due to secondary exposure fogging. Following the development trend of the times, our company has developed and produced a new type of environmentally friendly medical laser pri...
