Abstract
In a process involving at least two film-shaped substrates () bonded together by means of at least one adhesive layer containing a catalyst which accelerates hardening of the adhesive, a first substrate () is coated with a liquid film comprising three layers viz., two adhesive layers () and an intermediate layer (), which is situated between the adhesive layers () and contains a catalyst (), using liquid film coating in the form of curtain coating or slide-coating and subsequently bonded onto the second substrate (). The laminate () formed may be coated via at least one liquid film coating with a further three layer liquid film comprising two adhesive layers () and an intermediate layer (), which is situated between the adhesive layers () and contains a catalyst (), using curtain coating or slide-coating and subsequently bonded onto at least one additional substrate () to form an additional laminate (). Using that process the hardening time for the adhesive coatings can be drastically reduced.
