Abstract: Stretchable, multilayer films are disclosed that include a thermoplastic polyurethane substrate and a thermoset coating, applied to the thermoplastic polyurethane substrate. The thermoset coating may comprise the reaction product of: an oligomeric polyester resin comprising the reaction product of: diols or polyols comprising from about 30 to about 99 mol % trimethylolpropane and from about 1 mol % to about 70 mol % neopentyl glycol, in each case based on the total molar amount of diols and polyols reacted, and dicarboxylic acids or polycarboxylic acids comprising from about 1 mol % to about 70 mol % of one or more cyclic or acyclic aliphatic acids having from 2 to 12 carbons, based on the total molar amount of dicarboxylic acids and polycarboxylic acids reacted.

Abstract: Stretchable films are disclosed, that include a coating layer comprising the reaction product of: an oligomeric polyester resin wherein the oligomeric polyester resin has a glass transition temperature (Tg) of ?15 to 10° C., a hydroxyl equivalent weight of 350 to 500 mgKOH/g; and an aliphatic isocyanate, isocyanurate, allophanate, or biuret. The coating of these films has a fingerprint removal haze under 2, a percent haze removal over 70 percent, an initial scratch/mar over 40% gloss retention, and a recovered scratch/mar over 85% gloss retention as measured by both % gloss retention after 24 hours and % gloss retention at 60° C., as defined herein.

Abstract: This invention relates to a carbamate functional thermosetting coating with a composition comprised of a carba-mate-functional acrylic and/or polyester polyol and an alkylated melamine-formaldehyde cross linker modified by an aliphatic polyester and an alkylated melamine. The polyester polyol is made of monomers including a 2,4,4-tetraalkylcyclobutane-1,3-diol and an aliphatic diacid. These polyester polyols can be used in blends with hydroxyl-functional or carbamate-functional acrylic resins or serve as the primary film former in a coating formulation.

Abstract: This invention relates to aliphatic polyester resins for use in coatings. More particularly this invention relates to aliphatic polyester resins containing 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) that exhibit improved scratch resistance when formulated into 1 K automotive clearcoats. These polyesters can be used as the sole resin in the clearcoat binder or in combination with carbamate-functional acrylic resins and/or hydroxyl-functional acrylic and polyester resins.
