Abstract:
An acetoacetate-functionalized alkyd resin, comprising the reaction product of:(a) from about 70 to about 97 wt % of an alkyd resin, having an acid number of from 0 to about 100 mg KOH/g, the alkyd resin comprising the reaction product of: (i) a diol, in an amount of from 0 to about 30 mol %; (ii) a polyol, present in an amount of from about 10 to about 40 mol %; (iii) a polyacid, present in an amount of from about 20 to about 40 mol %; (iv) a monofunctional acid, in an amount of from 0 to about 10 mol %; (v) a fatty acid, a fatty acid ester, or a naturally occurring oil, present in an amount of from about 10 to about 50 mol %; and (vi) a sulfomonomer, present in an amount from about 2 to about 10 mol %, wherein the mole percents are based on the total moles of (i), (ii), (iii), (iv), (v) and (vi); and(b) about 3 to about 30 wt % of an alkyl acetoacetate, wherein the weight percents are based on the total weight of (a) and (b).
