A modified epoxy acrylate and a solder mask comprising same, relating to the technical field of synthetic resins. A long-chain aliphatic chain is added to a branch of carboxylic acid epoxy acrylate to prepare a modified epoxy acrylate. A solder mask comprising the modified epoxy acrylate maintains good adhesion, hardness, solvent resistance, and weather resistance of a photosensitive solder resist ink, keeps the sensitivity and the alkaline development in the exposure, and causes the prepared cured product to have good water resistance, electrical insulation, etc. Meanwhile, a material also achieves good flexibility after being photocured so as to widen the application of the material in a photosensitive imaging ink material. |
