ABSTRACT:
An alkyd resin comprising a polymerized product of from 25 to 40 percent by weight of trimethylolpropane diallyl ether, from 15 to 30 percent by weight of aromatic acid, from 20 to 40 percent by weight drying compound and from 7 to 16 percent by weight polyol.
The invention also includes solutions and dispersions of the resin of the invention and coatings made from the resin or solutions or dispersions thereof.
The resin is characterized by being compatible with solvents such as mineral spirits and having good drying properties and being able to form strong flexible films which are resistant to yellowing, and which have low water sensitivity.
Prior to the present invention, a non-yellowing alkyd resin having such a combination of properties was unavailable.
