| abstract |
THE INVENTION RELATES TO A COATING COMPOSITION WITH A HIGH SOLID CONTENT, COMPRISING: TO A FILM-GENERATING POLYMER CARRYING ONE OR MORE FUNCTIONAL GROUPS CAPABLE OF REACTING WITH THE CURING AGENT D DEFINED BELOW; B A VOLATILE ORGANIC LIQUID THINNER AS A CARRIER FOR POLYMER A; C MICRO PARTICLES OF POLYMER WITH AN AVERAGE DIAMETER OF 0.02 TO 40 MM, WHICH ARE INSOLUBLE IN THE COMBINATION OF FILM-FORMING POLYMER A AND THINNER B AND ARE KEPT IN A STABILIZED DISPERSION IN THESE AND OF A DISSOLVING CURING AGENT IN THE THINNER B. IN THE COMPOSITION ACCORDING TO THE INVENTION, MICROPARTICLES C ARE COMPOSED OF A CROSS-LINED COPOLYMER OF A, B-ETHYLENIC MONOMERS CARRYING A RESINOUS PORTION HAVING AMPHOTERIC GROUPS OF GENERAL FORMULA: (CF DRAWING IN BOPI) IN WHICH R IS A GROUP ALKYLENE IN CC TO PHENYLENE, OPTIONALLY SUBSTITUTED, AND IS A -COOH OR -SOH GROUP. |
