Abstract
Heat-sensitive paper capable of resisting chemi-thermomechanical pulp consists of a body paper layer, a precoating layer and a color developing layer, or consists of a body paper layer and a color developing layer. The body paper layer contains chemi-thermomechanical pulp content, and the precoating layer and the color developing layer are sequentially arranged on the body paper layer or only the color developing layer is arranged on the body paper layer. The color developing layer is prepared by, by weight, 10-30 parts of color-developing agent, 5-15 parts of leuco dyestuff, 10-30 parts of sensitizer, 5-15 parts of lubricant, 5-15 parts of adhesive, 10-35 parts of inorganic fillers, 5-10 parts of organic fillers, 1-5 parts of antioxidant and 0.1-2.0 part of accessory ingredient. The heat-sensitive paper is not influenced by chemi-thermomechanical pulp body paper. Even if the temperature reaches 60 DEG C and the humidity reaches 90% relative humidity (RH), heat-sensitive paper is placed for 100 hours, printed heat-sensitive paper also has excellent color developing depth, thereby prolonging storage life of the heat-sensitive paper greatly and solving the problem that the printed heat-sensitive paper which contains the chemi-thermomechanical pulp content and is placed for a period of time is light in color developing or cannot develop color.
