epoxy constituent, it is often not possible to give

  
precise indications for each case; however, it is generally assumed that UV absorbers transform <EMI ID = 3.1>

polyesters for the production of light-stable moldings and coatings of the above-mentioned type which contain "as an epoxy component (4)" or as a component thereof

  
 <EMI ID = 6.1> <EMI ID = 7.1> In general, the masses of polyesters will contain

  
 <EMI ID = 8.1>

  
 <EMI ID = 9.1>

  
 <EMI ID = 10.1>

  
 <EMI ID = 11.1>

  
the masses of polyesters will also advantageously be stabilized in the usual way against an undesirable polymerization, for example by a small quantity of hydrosol.

  
 <EMI ID = 12.1>

  
The hardening of the polyester masses may take place in the usual way, for example under the action of peroxides, organic, as well as, where appropriate, of accelerators, such as metal or amine salts.
