Polymeric vehicles which include a polyol, a phenolic ester alcohol and isocyanate compound

A polymeric vehicle comprising:

• at least about 5 weight percent, based upon the weight of the polymeric vehicle, of an isocyanate compound having an average isocyanate functionality of from about 1.9 to about 20 isocyanate groups per molecule;
• at least about 15 weight percent, based upon the weight of the polymeric vehicle, of a polyol having a polydispersity index greater than one and the polyol being selected from the group consisting of a polyester polymer, an acrylic polymer, an alkyd polymer, an epoxy polymer and mixtures thereof;
• and
• at least about 5 weight percent, based upon the weight of the polymeric vehicle, of a phenolic ester alcohol having at least one phenolic hydroxyl group, and at least one aliphatic hydroxyl group,
• the isocyanate compound being reactive with the phenolic ester alcohol and polyol, and wherein the phenolic ester alcohol has at least two ester groups and has the general formula ##STR26## wherein R.sub.4 is selected from the group consisting of hydrogen, halogen, hydroxyl, C.sub.1 to C.sub.8 alkyl and C.sub.1 to C.sub.8 alkoxy,
• R.sub.5 is selected from the group consisting of a direct bond, C.sub.1 to C.sub.20 organic radical having only carbon and hydrogen atoms, and a C.sub.1 to C.sub.20 organic radical which includes in its structure a substitution group selected from the group consisting of phenol, aliphatic hydroxyl, ester, ether, carbonate and combinations thereof,
• wherein R.sub.6 is selected from the group consisting of hydrogen, a C.sub.1 to C.sub.20 organic radical, a C.sub.1 to C.sub.20 organic radical which includes in its structure at least one ester linkage or a direct bond which forms with R.sub.7 part of a 5 or 6 carbon atom cyclic ring structure,
• wherein R.sub.7 is CH.sub.2 R.sub.8 wherein R.sub.8 is selected from the group consisting of hydroxy, OR.sub.9, ##STR27## and R.sub.11, wherein R.sub.9 is selected from the group consisting of a primary or secondary aliphatic group containing 3 to 20 carbon atoms, an aromatic group containing 6 to 20 carbon atoms, a primary aliphatic group containing 3 to 20 carbon atoms which includes at least one ester linkage and a secondary aliphatic group containing 3 to 20 carbon atoms which includes at least one ester linkage,
• wherein R.sub.10 is selected from the group consisting of a primary aliphatic group containing 4 to 20 carbon atoms, a secondary aliphatic group containing 4 to 20 carbon atoms, a tertiary aliphatic group containing 4 to 20 carbon atoms, an aromatic group containing 6 to 20 carbon atoms, and combinations thereof, wherein the primary, secondary and tertiary aliphatic groups include at least one ester linkage;
• and
• wherein R.sub.11 is selected from the group consisting of a C.sub.2 to C.sub.20 organic radical, a C.sub.2 to C.sub.20 organic radical which includes in its structure at least one ester linkage, a C.sub.2 to C.sub.20 organic radical which forms with R.sub.6 part of a 5 or 6 carbon atom cyclic ring structure, and combinations thereof.
