ABSTRACT:
Coating compositions having a high degree of elasticity, as well as toughness, durability and good metallic pigment pattern control are disclosed. This combination of properties makes the coatings particularly desirable for use on elastomeric substrates such as those associated with automobiles. The coating compositions comprise as a resinous component, an ungelled hydroxyl-containing polyester of high weight average molecular weight. The polyesters can be cured with a curative such as an aminoplast to give coatings having outstanding elastomeric properties and good pigment dispersibility, particularly good metallic pigment pattern control, properties not normally associated with polyesters for use in coating applications.
