Example Embodiment
[0044] Invention Example 1
[0045] 103 g of pyromellitic dianhydride and 210 g of diethylene glycol monoethyl ether acetate were added to a reactor equipped with a thermometer, a stirrer, a reflux condenser and a dropping funnel. The mixture was then heated to 100°C and stirred at a constant temperature for 1.5 hours. Then slowly add 59g 1,6-hexanediol and control the addition within 1 hour. Then, react at a constant temperature at 110° C. for 6 hours until the acid value is less than 145 mgKOH / g to obtain a carboxyl-containing polyester compound.
[0046] Subsequently, the temperature in the reactor was lowered to 90°C, and 109g of propylene glycol methyl ether acetate and 0.1g of inhibitor hydroquinone were added first, and after stirring at a constant temperature for 30 minutes, 0.12g of polymerization inhibitor was added Phenol, 1.7g catalyst N, N-dimethylbenzylamine and 76.5g glycidyl methacrylate. After the reaction for 16 hours, a polyester-type alkali water-soluble phot...

[0047] Invention Example 2
[0048] 54.53 g of pyromellitic dianhydride and 105 g of N-methylpyrrolidone were added to a reactor equipped with a thermometer, a stirrer, a reflux condenser and a dropping funnel. The mixture was then heated to 100°C and stirred at a constant temperature for 1.5 hours. Then 54g of hydrogenated bisphenol A was slowly added and the dripping was controlled within 1 hour. Then, react at a constant temperature at 110° C. for 6 hours until the acid value is less than 135 mgKOH / g to obtain a carboxyl-containing polyester compound.
[0049] Subsequently, the temperature in the reactor was lowered to 90°C, and 95g of propylene glycol methyl ether acetate and 0.1g of inhibitor hydroquinone were added first, and after stirring at a constant temperature for 30 minutes, 0.12g of polymerization inhibitor terephthalic was added. Phenol, 0.75g catalyst N, N-dimethylbenzylamine and 25.84g allyl-2,3-glycidyl ether. After reacting for 12 hours, a polyester-type alkal...

[0050] Invention Example 3
[0051] 54.53 g of pyromellitic dianhydride and 105 g of N-methylpyrrolidone were added to a reactor equipped with a thermometer, a stirrer, a reflux condenser and a dropping funnel. The mixture was then heated to 100°C and stirred at a constant temperature for 1.5 hours. Then 54g of hydrogenated bisphenol A was slowly added and the dripping was controlled within 1 hour. Then react at a constant temperature at 110°C for 6 hours, until the acid value is less than 135mgKOH / g to obtain a carboxyl-containing polyester compound;
[0052] Subsequently, the temperature in the reactor was lowered to 90°C, and 95g of propylene glycol methyl ether acetate and 0.1g of inhibitor hydroquinone were added first, and after stirring at a constant temperature for 30 minutes, 0.12g of polymerization inhibitor terephthalic was added. Phenol, 0.75g catalyst N, N-dimethylbenzylamine and 44.3g 3,4-epoxycyclohexylmethylmethacrylate. After reacting for 12 hours, a polyester-t...
