Abstract: The present invention discloses modified epoxy acrylates and the solder resist containing the epoxy modified acrylates, belonging to the synthetic resin field. In this invention, modified epoxy acrylates are prepared by introducing long fatty hydrocarbon chain as the branched chain into the carboxylated epoxy acrylates. The as-prepared solder resist containing this modified epoxy acrylates maintains the excellent property of photosensitive solder resist such as good adhesion, hardness, solvent resistance and weather resistance which facilities sensitivity and alkaline development during exposure simultaneously. This has led to good water resistance, electrical insulation of the cured products. Furthermore, the cured product also shows good flexibility which improves its application in photosensitive imaging ink materials.
