1. A method for producing a curable resin in a one-pot, two step reaction, said method comprising:
i) reacting an organic compound having at least one hydroxy group with a (meth)acrylic anhydride to produce a reaction product containing a (meth)acrylic ester and (meth)acrylic acid, wherein the organic compound having at least one hydroxy group is either a) or b)
a) an alcohol selected from the group consisting of methanol, ethanol, propanol, butanol, pentanol, hexanol, cyclohexanol, octanol and mixtures thereof, or
b) a polyol selected from the group consisting of ethylene glycol, propylene glycol, polyethylene glycol oligomers, polypropylene glycol oligomers, hexanediol, glycerol, and pentaerythritol;
ii) reacting said reaction product from step i) with at least one organic compound containing at least one epoxy group to form a second reaction product; and
iii) optionally blending the second reaction product from step ii) with up to about 75 wt.% of a reactive diluent, based on a total weight of the second reaction product from step ii), to produce the curable resin.
