Abstract

The invention discloses a photochromic material for laser printing and a manufacturing method thereof and printing paper. The material is prepared from, by mass, 15%-25% of inorganic chromogenic materials, 10%-20% of organic electron donor materials and 54%-75% of water. The technical problems that existing printing paper is low in reusing rate and poor in water resistance and heat resistance are solved.

Description

technical field [0001] The invention relates to the field of laser printing, in particular to a photochromic material for laser printing, a manufacturing method thereof and printing paper. Background technique [0002] Papermaking is one of the greatest inventions affecting the development of world civilization. As the carrier of characters and culture, paper brings great convenience to people's work and study, makes the spread of culture more convenient, and promotes the development of human civilization. However, the extensive use of paper also brings a series of problems. The traditional paper industry has huge energy consumption and serious pollution. According to the "2013 Environmental Statistical Annual Report" issued by the Ministry of Environmental Protection, in the survey and statistics of 41 industrial industries nationwide , the paper and paper products industry became the largest polluting industry. In the process of writing and printing on paper, it is inevit...
