Abstract:
A tertiary carboxyl functional polyester resin produced by reacting:a) at least one aliphatic compound A comprising two aliphatic hydroxyl groups which may each independently be a primary or secondary hydroxyl group and a tertiary carboxyl group,b) optionally one or more hydroxyl compounds B, each compound comprising two aliphatic hydroxyl groups which may each independently be a primary or secondary hydroxyl group,c) at least one cycloaliphatic carboxylic acid compound C comprising two secondary aliphatic carboxyl groups or the anhydride thereof,d) optionally one or more dicarboxylic acid compounds D comprising two aliphatic carboxyl groups or the anhydride thereof, ande) optionally either one or more compounds E comprising one primary or secondary hydroxyl group and optionally a tertiary carboxyl group, or one or more monocarboxylic acid compounds (G) comprising a primary or secondary carboxyl group, together with equivalent molecular amounts of one or more compounds (F) selected from the groups for A and B,the molar ratio of compounds (A+B):(C+D):E:F:G being (X-1):X:K:L:M, wherein X ranges from 2 to 14, K ranges from 0 to 2, L ranges from 0 to 2 and M ranges from 0 to the value of L.
