Organic resin that is soluble in organic media, characterized in that it comprises structural units in its overall composition obtained from: a) at least one ethylenically unsaturated monomer carrying a cyclic carbonate group, preferably selected from vinyl carbonates or ethylenically unsaturated esters carrying a cyclic carbonate group, b) at least one ethylenically unsaturated monomer carrying at least one carboxylic acid group, c) at least one ethylenically unsaturated monomer with a hydrophobic nature having a hydrophobic value, estimated by the logarithm of the partition coefficient between octanol and water logKow of at least 3, preferably at least 3.5, more preferably at least 4 and still more preferably at least 4.5, with logKow being calculated using the 'Estimation Program Interface Suite KowWin 4.11' software from Syracuse Research Corporation according to the methodology described by W. M. Meylan and P. H. Howard in 1995 in "Atom/fragment contribution method for estimating octanol-water partition coefficients" in Pharm. Sci. 84: 83-9, and said monomer c) comprising at least one linear or branched aliphatic group comprising at least 6 carbon atoms and/or at least one cycloaliphatic structure with at least 6 carbon atoms, preferably from 6 to 12 carbon atoms, d) optionally, at least one other ethylenically unsaturated monomer that is different from said monomers a), b) or c) and does not carry any group that is susceptible of reacting with a carbonate group or carboxylic acid group, but also no group that is susceptible of reacting with a functional group of another monomeric component of said resin, all cross-linking reactions in the preparation of said resin being excluded, overall, said resin having: - an acid value of at least 10, preferably 15 to 50, more preferably 15 to 40 mg KOH/g with respect to the dry resin, and - a cyclic carbonate group content of 0.5 to 3.5 mmol/g, preferably 0.9 to 3 mmol/g, more preferably 1.5 to 2.5 mmol/g with respect to the dry resin, and preferably said resin having an overall hydrophobic value, based on the logarithm of the partition coefficient between octanol and water, in particular estimated by the weighted average of logKow over the entirety of the monomeric constituents, of at least 1.5, preferably at least 1.6, with logKow of the monomeric constituents being calculated as defined above for monomer c). a) at least one ethylenically unsaturated monomer carrying a cyclic carbonate group, preferably selected from vinyl carbonates or ethylenically unsaturated esters carrying a cyclic carbonate group, b) at least one ethylenically unsaturated monomer carrying at least one carboxylic acid group, c) at least one ethylenically unsaturated monomer with a hydrophobic nature having a hydrophobic value, estimated by the logarithm of the partition coefficient between octanol and water logKow of at least 3, preferably at least 3.5, more preferably at least 4 and still more preferably at least 4.5, with logKow being calculated using the 'Estimation Program Interface Suite KowWin 4.11' software from Syracuse Research Corporation according to the methodology described by W.
