Abstract
A tonable, photosensitive composition, the adhesion properties of which are controlled by a polycaprolactone having an average molecular weight of at least 50,000 and a process for preparing polychromatic images by means of such a composition are described.
Claims6
A tonable, photosensitive composition comprising:
- (a) at least one ethylenically unsaturated, photopolymerizable compound which, upon exposure to actinic radiation, modifies the tackiness of the composition;
- (b) a photoinitiator or a photoinitiator system;
- (c) optionally a polymeric binder or a binder mixture;
- and
- (d) at least one polycaprolactone with a weight average molecular weight of at least 50,000 to influence the adhesion properties of the composition.
