Abstract: The invention relates to acetoacetylated lignin resin compositions comprising the reaction product of lignin and an acetoacetate ester. The invention also relates to (meth)acrylated lignin resin compositions comprising the reaction product of lignin and a (meth)acrylic compound. The invention also relates to methods of making the acetoacetylated and (meth)acrylated lignin resin compositions. The invention also relates to curable coating compositions comprising the acetoacetylated and (meth)acrylated lignin resin compositions. The invention also relates to methods of making the curable coating compositions of the invention. The invention also relates to methods of applying curable coating compositions of the invention to substrates. The invention also relates to articles of manufacture comprising a curable coating composition of the invention and a method of making such article. The invention also relates to foam materials comprising the reaction product of an acetoacetylated resin composition, a polyamine compound, and a physical blowing agent and/or a polysiloxane compound.
