The invention discloses an active pigment resin printing imitation binder, which is prepared from the following raw materials in parts by weight: 35 to 39 parts of polyester acrylate, 9 to 12 parts of sodium dodecylpoly(oxyethylene) sulfate, 8 to 10 parts of 2-ethylhexyl acrylate, 2 to 3 parts of methacrylamide, 10 to 12 parts of methyl acrylate, 4 to 5 parts of acrylonitrile, 1 to 2 parts of acetylacetone selenium, 9 to 12 parts of tripropylene glycol diacrylate, 7 to 9 parts of dipentaerythritol hexaacrylate, 2 to 3 parts of 2-ethylhexyl phosphate, 1 to 2 parts of ammonium persulfate, 4 to 5 parts of accessory and 80 to 90 parts of water. The binder is high in light fastness, thermal resistance, elasticity and color fastness, and dust in air cannot be adsorbed; due to the addition of the acrylonitrile, the methacrylamide and the like for modification, the binder cannot be hydrolyzed easily like pure polyester acrylate, and is high in water resistance; the printing hand-feel of a product is comparable with an active pigment resin printing hand-feel, and the product has the advantage of bright color.
