1. An RMA crosslinkable fatty resin containing one or more fatty components selected from the group of fatty acids, fatty alcohols, fatty amines, fatty thiols and at least 2 reactive groups which are acidic protons (C—H) in activated methylene or methine groups wherein the activated C—H reactive groups are in one or more reactive components A, wherein the RMA crosslinkable fatty resin is modified with a reactive component A having a structure according to formula 1:

OG Complex Work Unit Chemistry
wherein R is hydrogen or an alkyl or aryl and Y and Y′ are identical or different substituent alkyl, aralkyl or aryl (R*), or alkoxy (—OR*) groups, or wherein the —C(═O)—Y and/or —C(═O)—Y′ is replaced by CN or aryl,
wherein the one or more reactive components A are predominantly malonate, predominantly meaning that more than 50% of the C—H reactive groups in the crosslinkable fatty resin are from malonate,
wherein the crosslinkable fatty resin comprises fatty components in an amount of 5 to 40 wt % relative to total weight of the crosslinkable fatty resin and comprises reactive components A in an amount between 10 and 40 wt % relative to total weight of the crosslinkable fatty resin,
wherein the fatty components have a carbon length from 4-28,
wherein the fatty resin is further characterised by:
a) a weight average molecular weight Mw between 2000 and 15000 gr/mol,
b) a hydroxy value OHV between 20-300 mgKOH/gr,
c) an acid value AV below 3 mg KOH/g,
d) an equivalent weight EQW per reactive C—H group between 125 and 300 gr/mol,
e) a functionality defined as number average number of reactive C—H per molecule between 4 and 12,
f) a glass transition temperature Tg between 220 and 320K as measured by DSC.
