REACTIVE LACQUER COMPOSITION BASED ON UNSATURATED POLYESTERS AND A PROCESS FOR ITS MANUFACTURE

The subject of the invention is a process for the production of coatings from polyhydroxy compounds, based on copolymers containing hydroxyl groups, and polyisocyanates in solvents having no active hydrogen atoms, by shaping whilst removing the solvent. The copolymers which are used according to the invention give lower viscosities than the known copolymers. These less viscous copolymer solutions exhibit a better absorption of pigment both when using inorganic or organic pigments. The reactive lacquer manufactured therefrom produce high-gloss films. The films of the reactive lacquers used in the process of the invention have the following advantages: better resistance to solvents, higher abrasion resistance and better resistance to weathering in the Florida climate. In addition, the copolymers used according to the invention, when combined with polyisocyanates and diluted as described give lacquers of higher solids content. By the invention, an acrylic resin is provided, containing hydroxyl ...
