Curable polyester polyols and their use in thermosetting soft feel coating formulations

A curable coating composition comprising:

• A) a curable aliphatic polyester composition comprising the residues of:
• i. a hydroxyl component, said hydroxyl component comprising the residues of:
• a) from 30 to about 90 mole %, based on the total moles of a) and b) of 2,2,4,4-tetraalkylcyclobutane-1,3-diol represented by the structure
• wherein R1, R2, R3, and R4 each independently are C1 to C8 alkyls;
• b) from 10 to 70 mole % based on the total moles of a) and b) of a C2-C20 diol other than 2,2,4,4-tetraalkylcyclobutane-1,3-diol;
• c) from 5 to 60 mole %, based on the total moles of a), b) and c) of a C2-C20 polyol;
• ii. a diacid component, said diacid component comprising the residues of:
• d) from 70 to about 100 mole %, based on the total moles of d) and e) of an alicyclic diacid;
• and
• e) from 0 to 30 mole %, based on the total moles of d) and e) of an acyclic aliphatic diacid;
• and
• wherein said curable polyester contains at least 90 mole percent of aliphatic diacid residues, based on the total moles of diacid residues, and wherein said curable polyester has a hydroxyl number of about 100 to about 250 mgKOH/g, an acid number of 0 to about 30 mgKOH/g, and a number average molecular weight of about 500 to about 10,000 g/mole;
• B) a polyol selected from polycarbonate diol, polytetramethylene glycol, or polycaprolactone;
• C) a crosslinker;
• and
• D) a solvent;
• wherein said curable polyester (A) is present in an amount from 10 to 50 weight %;
• said polyol (B) is present in an amount of from 50 to 90 weight %, said crosslinker (C) is present in an amount of from 10 to 50 weight % based on the total weight of said polyester (A), said polyol (B) and said crosslinker (C) in said coating composition.
