Embodiment 1
[0022] The invention provides a modified photocurable polyester acrylic resin, the modified photocurable polyester acrylic resin comprises the following components in parts by mass: 100 parts of trimethylolpropane, 60 parts of benzoic acid, 50 parts of phthalic anhydride, 15 Parts of xylene, 150 parts of trimethylolpropane triacrylate, 15 parts of epoxidized soybean oil, 50 parts of rosin, 30 parts of acrylic acid, 1.5 parts of p-toluenesulfonic acid, 1.5 parts of triphenylphosphine, 0.3 parts of p-phenylene Diphenol and 0.2 parts of BHT.
[0023] The above-mentioned modified photocurable polyester acrylic resin improves the wetting and dispersibility of the resin to organic pigments by introducing rosin with a honeycomb structure and adding epoxy soybean oil, so that the gloss and transfer performance of the ink are significantly improved, and, due to The molecular weight of rosin and epoxidized soybean oil is relatively large. The introduction of such high molecular weight s...
