A coating composition comprising a first component having a first
polyester polyol having a first functionality, and a second polyester
polyol having a second functionality, wherein the second functionality is
greater than the first functionality, and a second component comprising
an isocyanate, wherein the coating has an NCO:OH ratio of 1:1 or greater
is disclosed. A coated flexible substrate comprising a flexible
substrate, and a coating deposited on at least a portion of the
substrate, wherein the coating comprises a first component having a first
polyester polyol having a first functionality and a second polyester
polyol having a second functionality, wherein the second functionality is
greater than the first functionality and a second component comprising an
isocyanate is also within the scope of the present invention.
