摘要： The present invention provides a water soluble polymer which is prepared by the following steps. First, a carboxyl group-containing polymer is reacted with an alkaline reagent so that a portion of the carboxyl groups are reacted in an amount sufficient to make the polymer water soluble. Then, the polymer obtained is reacted with an epoxide containing unsaturated bonds and/or heteroatoms so that 1 to 100 mole percent of the remaining carboxyl groups of the polymer are reacted with the epoxide to form ester groups via a ring-opening reaction of epoxides, wherein the heteroatom can be silicon, nitrogen, phosphorus or sulfur. The water soluble polymer of the present invention can be used as a photosensitive resin. When the photoresist composition is used for preparing printed ciruit boards, it exhibits high photosensitivity, good water dispersability, storage stability, and good adhesion to copper. In addition, the problem of sticking to the mask can be prevented.
