FIELD: chemistry. ^ SUBSTANCE: composition contains a radiation-curable olibomer, having glass transition temperature Tg and/or melting point Tm lower than 30C. The radiation-curable oligomer is obtained through reactionof one or more carboxyl functional polyesters with one or more monoepoxides modified with a (meth)acrylic compound, and/or one or more polyepoxides and one or more , -unsaturated carboxylic acids. ^ EFFECT: obtaining coating compositions, having good chemical resistance, solvent resistance, scratch resistance and surface hardness coupled with improved flexibility, adhesion and scratching during flexure and fast deformation, improved corrosion resistance and improved heat resistance and good electrical insulation properties. ^ 12 cl, 2 tbl, 29 ex |
