An RMA crosslinkable coating composition having easy to clean properties comprising at least one crosslinkable component, the at least one crosslinkable components comprising reactive components A and B each comprising at least 2 reactive groups wherein the at least 2 reactive groups of component A are acidic protons (C-H) in activated methylene or methine groups (RMA donor group), and the at least 2 reactive groups of component B are activated unsaturated groups (C=C) (RMA acceptor group), which react to achieve crosslinking by Real Michael Addition reaction between said at least one crosslinkable components in the presence of a base catalyst, said crosslinkable composition is characterized in that a. the composition comprises fatty components selected from the group of fatty acids, fatty alcohols, fatty amines, fatty thiols and dimeric fatty acid, b. in an amount represented by an Oil Content OC between 0 and 40 wt%, preferably being at least 4, more preferably at least 10 or more preferably at least 14 wt% defined as the total weight of fatty components relative to the total solids weight of the crosslinkable composition as defined in paragraph of the description, and wherein c. the components in the crosslinkable composition are chosen such that after curing a coating is formed having a polymer network crosslinking density XLD, not including pigment effects, of at least 1.4, preferably at least 1.6, more preferably at least 1.9, even more preferably at least 2.5, most preferably at least 3.5 mmoles/g as determined by DMTA measurement on a cured coating film as defined in paragraphs and to of the description, and wherein d. the components in the crosslinkable composition are chosen such that after curing a coating is formed having, not including pigment effects, a glass transition Tg as determined by DMTA measurement as defined in paragraph and to of the description of at least 290, preferably at least 300K, more preferably at least 305 at least 310 K and 320 more preferably at least 330 K, e. and wherein OC, XLD and Tg are chosen in combination sufficiently high that the cleaning parameter ΔE is less than 20, preferably less than 15, more preferably less than 10 and most preferably less than 5 as measured by colour difference measurement before and after applying-and-cleaning of pigment as described in the description paragraph -. a. the composition comprises fatty components selected from the group of fatty acids, fatty alcohols, fatty amines, fatty thiols and dimeric fatty acid, b. in an amount represented by an Oil Content OC between 0 and 40 wt%, preferably being at least 4, more preferably at least 10 or more preferably at least 14 wt% defined as the total weight of fatty components relative to the total solids weight of the crosslinkable composition as defined in paragraph of the description, and wherein c. the components in the crosslinkable composition are chosen such that after curing a coating is formed having a polymer network crosslinking density XLD, not including pigment effects, of at least 1.4, preferably at least 1.6, more preferably at least 1.9, even more preferably at least 2.5, most preferably at least 3.5 mmoles/g as determined by DMTA measurement on a cured coating film as defined in paragraphs and to of the description, and wherein d. the components in the crosslinkable composition are chosen such that after curing a coating is formed having, not including pigment effects, a glass transition Tg as determined by DMTA measurement as defined in paragraph and to of the description of at least 290, preferably at least 300K, more preferably at least 305 at least 310 K and 320 more preferably at least 330 K, e. and wherein OC, XLD and Tg are chosen in combination sufficiently high that the cleaning parameter ΔE is less than 20, preferably less than 15, more preferably less than 10 and most preferably less than 5 as measured by colour difference measurement before and after applying-and-cleaning of pigment as described in the description paragraph -.
