Beschreibung
Zusammenfassung:	A protective coating composition containing certain polymer polyols and an aminoplast derivative is applied to a thermoplastic substrate to produce a thermoformable article having mar- and solvent- resistance. Une composition de revêtement protecteur contenant certains polyols de polyester et un dérivé d'aminoplaste est appliquée sur un substrat thermoplastique pour produire un article thermoformable présentant une résistance au rayage et aux solvants.
