Compositions containing adducts of cyclopentadiene and its use for chemical resistant coatings.

Composition comprising: (a) at least one component selected from phenolic resins, amino resins, polyfunctional isocyanates and derivatives thereof, and (b) at least one adduct of cyclopentadiene as an additional component obtainable by reacting at least one sterically unsaturated product optionally substituted cyclopentadiene with where steric unsaturated product is obtained by reacting an alcohol component, comprising a mono- or polyhydric alcohol with a carboxylic acid component comprising a mono- or polyvalent carboxylic acid, or a derivative thereof, with the proviso that the mono- or polyhydric alcohol and / or mono- or polyvalent carboxylic acid having at least one nonaromatic double bond, and with the proviso that the mono- or polyhydric alcohol or mono- carboxylic acid or polyvalent, or both, are polyvalent, wherein component (b) has functional groups (B), with the functional groups (a) of cpd onente (a) they can formaruniones chemical.
