Abstract
The invention relates to a curable composition including (a) a component having one or more carbonyl group-containing compounds having a number average molecular weight (Mn) of at least 500 g/mole, wherein each carbonyl group is independently a ketone group or an aldehyde group; (b) a polyamine compound having at least two primary amine groups per molecule; and (c) a polyisocyanate compound. Articles coated with the curable composition are also provided.
Claims13
A curable composition, comprising:
- (a) a component comprising one or more carbonyl group-containing compounds having a number average molecular weight (Mn) of at least 500 g/mole, wherein each carbonyl group is independently a ketone group or an aldehyde group,
- wherein the component (a) comprises (i) a compound having 1 to 4 carbonyl groups per molecule and an equivalent weight of 500 to 30,000 g/mole,
- wherein the compound (i) is selected from the group consisting of carbonyl group-containing polycarbonates, carbonyl group-containing polyethers, carbonyl group-containing polyesters, copolymers thereof, and mixtures thereof;
- (b) a polyamine compound having at least two primary amine groups per molecule;
- and
- (c) a polyisocyanate compound, wherein the polyisocyanate compound has at least two isocyanate groups per molecule and an equivalent weight of less than or equal to 500 g/mole.

A coated article comprising:
- a substrate;
- and
- a cured coating layer over at least a portion of the substrate, wherein the cured coating layer is formed from a curable coating composition comprising:
- (a) a component comprising one or more carbonyl group-containing compounds having a number average molecular weight (Mn) of at least 500 g/mole, wherein each carbonyl group is independently a ketone group or an aldehyde group, wherein the component (a) comprises a compound having 1 to 4 carbonyl groups per molecule and an equivalent weight of 500 to 30,000 g/mole, wherein said compound is selected from the group consisting of carbonyl group-containing polycarbonates, carbonyl group-containing polyethers, carbonyl group-containing polyesters, copolymers thereof, and mixtures thereof;
- (b) a polyamine compound having at least two primary amine groups per molecule;
- and
- (c) a polyisocyanate compound, wherein the polyisocyanate compound has at least two isocyanate groups per molecule and an equivalent weight of less than or equal to 500 g/mole.
