A coating composition is based on a polyester mixed with an alkyl-etherified melamine formaldehyde. The coating composition is partially cured in a first stage to provide a thermoformable partially cured, tack-free, non-blocking, coating layer, followed by application to generally a contoured substrate and thermoforming to conform thereto. The contoured partially cured coating layer is then heat cured to form a cured coating. A hydroxyl-terminated polyoxetane containing repeat units derived from oxetane monomers having one or two pendent &#x2014;CH&#x2014;O&#x2014;(CH)&#x2014;Rf groups, wherein Rf is partially or fully fluorinated, can be esterified with polyester-forming reactants to form a fluorinated polyoxetane-modified polyester.

A reactive fluorinated polymer having polyester and polyether segments is mixed with a reactive melamine resin to form a coating composition. The polyether segment can include monomeric units from an oxetane monomer having pendant fluorine groups that are linked to the oxetane via an ether group. The melamine resin can be a lower alkyl etherified melamine-formaldehyde. The composition can be disposed on a substrate and treated to form a laminate.

Acrylate, or methacrylate, or allylic, functionalized polyfluorooxetanes are disclosed for use in radiation curable coating compositions. These acrylate, or methacrylate, or allylic, functionalized polymers provide improvements in wetting and surface properties that have previously been provided by migratory chemicals such as waxes and oils. The partially or fully fluorinated side groups of the fluorooxetanes are believed to be disproportionately present at the interfaces between the coating and the substrate and between the coating and the atmosphere.

The polymer of the present invention is derived from cyclic ether monomers, dioxane, dioxalane or trioxane and contains both pendant R fluoro groups as well as polar groups. These polymers have good wetting, or flow, or leveling properties. They can be reacted with other monomers, such as in the preparation of polyesters, and can be used in waxes, polishes and coatings.
