The invention relates to the technical field of digital ink jet, in particular to the field of IPC C09D 11, and more particularly relates to solder resist ink-jet ink and application thereof. The UV-curable UV-curable coating comprises the following components: 20-45% of special acrylic ester, 5-40% of a bifunctional acrylic monomer, 3-10% of a photoinitiator, 0.2-2% of an imidazole accelerator, 1-5% of color paste, 0.5-2% of an auxiliary agent and the balance of a monofunctional acrylic monomer. The viscosity of the digital ink-jet solder resist ink is 7-15 cps (45 DEG C), the surface tension is 26-34 mN/m, and the viscosity change is within 25% after the digital ink-jet solder resist ink is aged at 60 DEG C for 3 days. 本发明涉及数码喷墨技术领域，尤其涉及IPC C09D 11领域，更具体的，涉及一种阻焊喷墨墨水及其应用。组分包括：特种丙烯酸酯20-45％，双官能度丙烯酸单体5-40％，光引发剂3-10％，咪唑类促进剂0.2-2％，色浆1-5％，助剂0.5-2％，单官能度丙烯酸单体补足余量。所述数码喷墨阻焊墨水，粘度为7-15cps(45℃)，表面张力为26-34mN/m，60℃老化3天，粘度变化在25％以内。
