Abstract

The invention belongs to the technical field of printing ink and in particular relates to a scraping white ink for instant lottery ticket and a preparation method of the scraping white ink. The scraping white ink comprises modified acrylate, titanium dioxide, glycerol, a dispersant, acrylic acid resin, hydrogenated rosin methyl ester, a slipping agent and water. The preparation method of the scraping white ink comprises the following steps: 1) uniformly mixing the titanium dioxide, the dispersant and the water so as to obtain a first material; and 2) stirring and mixing the first material withthe modified acrylic acid resin, the hydrogenated rosin methyl ester, the glycerol and the slipping agent, so as to obtain the scraping white ink. By adjusting material constitution and proportioning, and reasonably matching the components to achieve a synergetic effect, the scraping white ink provided by the invention has the advantages of being good in dispersibility, good in covering property,excellent in comprehensive property, and the like, can be coiled after being scraped, and in addition is simple in preparation method, free of pollution, free of odor and beneficial to industrial production.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and in particular relates to a scratch-off white ink suitable for instant lottery tickets and a preparation method thereof. Background technique [0002] An instant lottery ticket is a printed paper product of specific specifications. For each instant lottery ticket, it usually includes a game area and a scratch area. The game area is printed with game rules, and the scratch area is printed with scratch numbers and / or winnings Number. The hierarchical structure of the lottery scratch area is black base, white base, winning information, UV isolation oil, black scratch off, white scratch off, and surface color images; the scratch black, scratch white, and surface color images are collectively referred to as The scratch-off layer, scratch-off black and scratch-off white are called scratch-off inks. The main function of the scratch-off layer is to cover the winning information on the bottom l...
