resins are not directly usable, or are unusable for many purposes, for which they would otherwise be suitable and for which it would even be desirable to use them because of their relatively low price * A process for improving resins of high quality is already known.

Unlike this known process, the present invention relates to a process for the selective preparation of oouma- resins.

  
 <EMI ID = 11.1>

  
to obtain from the latter, by precipitation of the dark constituents, the light constituents of the species of indene.

  
In accordance with the invention, 3 parts of resin are dissolved

  
 <EMI ID = 12.1>

  
matiques and the relatively fonoaceous constituents of an oumarone character are precipitated by means of a suitable solvent, for example by means of Fisoher - Tropeoh benzine, the compounds

which can be separated from the solvent by distillation * At the same time the solvent is recovered, except for the inevitable losses by evaporation.

The dark precipitated constituent of the resin is suitable, when dissolved in benzene, as a protective coating against

it is also suitable, thanks to its inoombustibility, as a plaster = for premises-) where there is a danger of fire *;
