【Abstract】 A kind of active ether compound with acetal structure was synthesized through the adding-reaction between ethyl vinyl ether and pyrogallol polycondensation resins.The optimized reaction conditions are as follows:35℃,the mixture of methylene chloride and acetone(50∶50) as the solvent,sulfamic acid as the catalyst,the molar ratio of vinyl ether to phenolic hydroxyl group being 3∶1,reacting for 14 h.This kind of active ether compound can be used in room temperature chemically amplified positive photosensitive imaging and positive thermal imaging as an inhibitational/accelerational reagent for being able to be acid-decomposed and heat-decomposed under room temperature.Being used in CTP thermal imaging directions,it makes for the plates’ high sensitivity,anti-alkaline and high stability.Being used in positive CTcP photosensitive imaging directions,it makes for the plates’ excellent performance of integrated imaging.Being used in positive photoresist imaging directions,it makes for the positive photoresist high sensitivity and high resolution.更多还原
