Abstract
A method for forming a multi-layer coating includes the step of sequentially applying a layer of a primer coating composition, a layer of a base coating composition, and a layer of a clear coating composition on a substrate. The clear coating composition includes a film forming binder and an organic liquid carrier. The film forming binder includes at least one monomer unit including the condensation product of an ethylenically unsaturated carboxylic acid group and glycidyl ester of a mixture of tertiary acids having 9 to 11 carbon atoms having at least one methyl group on the α-carbon. The method further includes the step of simultaneously curing the applied three layers by baking.
Claims21
A method for forming a multi-layer coating comprising the steps of:
- sequentially applying a layer of a primer coating composition, a layer of a base coating composition, and a layer of a clear coating composition on a substrate, wherein the clear coating composition comprises:
- a film forming binder and an organic liquid carrier, wherein the film forming binder comprises at least one monomer unit including the condensation product of an ethylenically unsaturated carboxylic acid group and glycidyl ester of a mixture of tertiary acids having 9 to 11 carbon atoms having at least one methyl group on the α-carbon;
- and
- simultaneously curing the applied three layers by baking.
(canceled)
A multi-layer coated substrate comprising:
- a substrate;
- a layer of a primer coating composition disposed over and in contact with the substrate;
- a layer of a base coating composition disposed over and in contact with the primer coating composition;
- and
- a layer of a clear coating composition disposed over and in contact with the base coating composition,
- wherein the clear coating composition comprises:
- a film forming binder and an organic liquid carrier, wherein the film forming binder comprises at least one monomer unit including the condensation product of an ethylenically unsaturated carboxylic acid group and glycidyl ester of a mixture of tertiary acids having 9 to 11 carbon atoms having at least one methyl group on the α-carbon, and
- wherein each of the primer coating composition, the base coating composition, and the clear coating composition are disposed on the substrate in a “wet” or un-cured state.
