Claims6
An hydroxy amide acetal composition of the formula
- wherein R42—R49 independently represent a hydrogen, C1-C20 alkyl, C1-C20 alkenyl, C1-C20 alkynyl, C1-C20 aryl, C1-C20 alkyl ester, or C1-C20 aralkyl group, said alkyl, alkenyl, alkynyl, aryl, or aralkyl may each have one or more substituents selected from the groups consisting of halo, alkoxy, imino, and dialkylamino;
- R41 is (CR50R51)n—OH, wherein R50 and R51 independently represent a hydrogen, C1-C20 alkyl, C1-C20 alkenyl, C1-C20 alkynyl, C1-C20 aryl, C1-C20 alkyl ester, or C1-C20 aralkyl group ;
- and
- n is 1-10.
