Patent ID: 7795371

Claim:
A grind resin comprising a reaction product of: (a) a dibasic acid; (b) optionally a polybasic acid; (c) a diol; (d) optionally a polyol; and (e) a fatty compound having a fatty chain and two reactive groups reactive with at least one of said dibasic acid and said diol; provided that less than or equal to 5% of all acid groups are provided by said polybasic acid, when present, and provided that less than 20% of all hydroxyl groups are provided by said polyol, when present; wherein said fatty compound is present in an amount of from 5 to 20 parts by weight based on 100 parts by weight of all components before reaction to form said reaction product; wherein said dibasic acid is present in an amount of from 30 to 40 parts by weight based on 100 parts by weight of all components before reaction to form said reaction product; wherein said reaction product is substantially free from branching comprising the reaction product of acid groups or hydroxyl groups and components (a), (b), (c), (d), or (e).
