Water Soluble Polyester Resin is a type of synthetic resin that is modified to be soluble in water. It is derived from polyester, a polymer made from polycondensation reactions between diols and dicarboxylic acids. The water solubility is achieved by incorporating hydrophilic groups, such as carboxyl or sulfonate groups, into the polyester backbone. This modification allows the resin to dissolve or disperse in water, making it environmentally friendly and easier t...
