Abstract
An adhesive release composition containing specific amounts of an organopolysiloxane bearing oxyalkylene groups and alkenyl groups, an organohydrogenpolysiloxane, and a platinum-type catalyst is characterized by the formation, on various base surfaces, of a release surface having an excellent printability and a stable release force. For example, a roll of pressure sensitive adhesive tape of this invention can be easily unrolled, durably adhered to an article and clearly printed with ink on its adhesive-releasing surface which bears the release composition of this invention.
