The invention relates to catechol modified acrylic resin with a hydroformylation function, emulsion paint and a preparation method of the catechol modified acrylic resin. The catechol modified acrylic resin is obtained by polymerizing an alkyl catechol oxyalkyl methacrylate functional monomer, a CH2 = CR1COOR2 monomer and a styrene monomer; the catechol modified acrylic resin is prepared into the emulsion paint containing the catechol modified acrylic resin, formaldehyde can be adsorbed and reacted to be decomposed into water, yellow pyridine ring products cannot be generated, and the whiteness persistence of a paint film is ensured. 本发明涉及一种具有醛化水功能的邻苯二酚改性丙烯酸树脂、乳液漆及其制备方法，通过烷基邻苯二酚氧烷基甲基丙烯酸酯功能单体、CH2＝CR1COOR2单体和苯乙烯单体聚合得到邻苯二酚改性丙烯酸树脂，并制成含有邻苯二酚改性丙烯酸树脂的乳液漆，可实现将甲醛吸附并发生反应分解成水，且不会产生黄色吡啶环产物，确保漆膜的白度持久度。
