A process for preparing a release liner for pressure-sensitive adhesives makes use of an organic-solvent solution of a rhodium-curable organopolysiloxane composition. The composition contains a high-viscosity, alkenyl-containing organopolysiloxane gum and an organohydrogenpolysiloxane. The liner is particularly useful for releasing acrylic adhesives which have been applied in-line thereto.

PURPOSE:To obtain a flexible printed board whose component reinforcing section is thin, and compact in size, but produces no harmful influence by providing a specified reinforcing member installed between a base circuit board and a cover lay film.
