Abstract
The present invention relates to protective coating formulations, in particular to transparent abrasion-resistant and scratch-resistant coatings on transparent thermoplastic polymers, which coatings essentially consist of a hydrolyzed siloxane compound, a dispersion of colloidal silicon dioxide, etherified methylolmelamine, a blocked polyisocyanate, acetic acid and a polysiloxane terminated by hydroxyl groups.
