Abstract:
A substantially ester-free, acid-functional thiol-functional resin is prepared via the reaction of an epoxy compound with a thiolacetic acid in the presence of an amine catalyst and heat to form a thioacetate derivative which is hydrolyzed to yield an ester-free,. beta. -hydroxy thiol-functional resin. The. beta. -hydroxy thiol-functional resin can then be reacted with a material capable of insert a group conferring aqueous-base developability such as a cyclic anhydride.
