Claim Text:
1. A branched polymer (S), obtained by a process comprising reacting a carbonyl compound (A) and an acrylate compound (B), wherein said branched polymer (S) comprises a hydroxyl group and an acrylate group, and wherein the carbonyl compound (A) is at least one carbonyl compound selected from the group consisting of a carbonyl compound (Ax) having more than two carbonyl groups and a dicarbonyl compound (A2) having just two carbonyl groups, the more than two carbonyl groups of the carbonyl compound (Ax) and the just two carbonyl groups of the dicarbonyl compound (A2) are selected independently from the group consisting of an aldehyde group and a keto group, and wherein the acrylate compound (B) is at least one acrylate compound selected from the group consisting of an acrylate compound (By) having more than two acrylate groups and a diacrylate compound (B2), in which an average functionality of the carbonyl compound (A), the acrylate compound (B), or a combination thereof, is more than 2.
