Abstract
Acryl modified polyester resins are prepared by a process which comprises reacting an acid mixture with an alcohol mixture to form hydroxyl polyester prepolymers, solution polymerizing acryl monomers with acidic acryl monomers having carboxyl groups to form acryl resins, and reacting said hydroxyl polyester prepolymers with said acryl resins and polycarboxylic acids having at least two carboxyl groups. A powder coating composition is composed of inorganic pigment or organic pigment, a flowing agent, a curing agent, a curing accelerator, other stabilizers and the acryl modified polyester resins prepared according to the above process.
