A water soluble and/or dispersible composition comprising a fatty oil or fatty acid modified, imidized polyester, said polyester being derived from aliphatic, cycloaliphatic or aromatic diols; polyhydroxy-alkanes other than diols; aliphatic, cycloaliphatic and/or aromatic dicarboxylic acids; and aromatic tricarboxylic acids.
Claim 2
Dependent Claim
40 words
A water soluble and/or dispersible composition comprising a fatty oil or fatty acid modified, imidized polyester, said polyester being derived from aliphatic, cycloaliphatic or aromatic diols; polyhydroxy-alkanes other than diols; aliphatic, cycloaliphatic and/or aromatic dicarboxylic acids; and aromatic tricarboxylic acids.
Claim 3
Dependent Claim
21 words
