Abstract: Disclosed is a masking article such as a masking tape, roll of masking tape, masking sheet, etc. that has a substrate or backing with a primer layer on a first major surface thereof and a pressure-sensitive silicone adhesive layer on the primer layer such that the primer layer is positioned between the backing and the adhesive layer. The masking article is able to adhere to a semi-permanent release composition at greater than about 10 oz/in as measured with a 90° peel test to stainless steel with a 4.5 lb roll down. A method of masking a mold having a semi-permanent release applied thereto with the disclosed masking article is disclosed. The method includes the steps of providing a mold having the semi-permanent release agent applied thereto and applying a masking article to an area of the mold with the masking article at least partially adhered to the semi-permanent release agent.
