摘要

1. Process for bringing about a protective product with a protective film capable of being transferred in the cold state by simple pressure, which can be used for covering end protecting on the surface a document or other object, characterised in that it consists in producing on a non-adhesive support foil (1) an imprint (2) by means of a liquid polymerisable two-component mixture containing a hydroxylated polyol and an isocyanate or polhisocyanate so as to cause polymerisation of the mixture in situ, leading to a thin transparent polyurethane film, and in covering said film with a transparent adhesive layer (3).
