Alky resin question

Is there any web pages that give an overview of "alkyd resins". I am looking for definitions and some chemical data. We have situations were a particle will have an IR spectrum that matches the infamous "alkyd resin" spectrum in our IR library. I would like to gain a better understanding of the chemistry behind alkyd resins.

Thanks,

Alkyds are basically a subgroup of the polyester family of resins. The term alkyd is a made with the al being an polyfunctional alcohol (two or more hydroxyl groups) and kyd is from acid (natural organic acids). This combination produces an ester. The organic acids are derived from fats or oils.
