The invention provides printing ink for an insulating layer of a shielding case. The printing ink is prepared from the following components in percentage by mass: 60-70% of polyester resin; 15%-20% ofdibasic ester; 5%-10% of pigment; 10%-20% of silicone oil; wherein the polyester resin is a polymer of dimethyl 1,3-phthalate, dimethyl-1,4-phthalate and 1,2-ethylene glycol; the dibasic ester is mixed dibasic acid dimethyl ester; the pigment is one or a mixture of 1,1'-[(6-phenyl-1,3,5-triazine-2,4-diyl)diimino]dianthraquinone and 1,1'-[(6-phenyl-1,3,5-triazine-2,4-diimino]dianthraquinone; the silicone oil is one or a mixture of more of methyl silicone oil, dimethyl silicone oil, polysiloxane, hard foam silicone oil, organic silicone oil and a foam stabilizer. The polyester resin is arrangedin the ink and has the advantages that the polyester resin is easy to wet and good in manufacturability, a cured adhesive layer is high in hardness, good in transparency, high in brightness, capableof being rapidly cured thro
