Abstract

The invention discloses an adhesive product comprising a poly(meth)acrylate primer layer and a preparation method thereof. The article can include a backing, a primer layer on a first major surface of the backing, and a silicone-based adhesive on the primer layer. The primer layer may be derived from a primer precursor containing poly(meth)acrylate functionality. The method may include applying a primer precursor to the first major surface of the backing, the primer precursor comprising a compound comprising poly(meth)acrylate functionality; irradiating the primer precursor; applying an adhesive on the irradiated primer precursor; and irradiating the adhesive and the irradiated primer precursor to form the adhesive between the adhesive and the backing A primer layer between the first major surfaces.

Description

Technical field[0001]The present disclosure relates to an adhesive article and a preparation method thereof, which comprises a poly (meth) acrylate primer layer for improving the adhesion of the binder on the backing.Background technique[0002]Due to the strong skin adhesion, low damage removal, good biocompatibility and high gas permeability, the use of silicone adhesives is increasing, especially in the health sector. The silicone-based adhesive is usually inert, so that the drug in which the adhesive structure (opposite to the reservoir-based configuration) is compatible with the adhesive configuration for transdermal administration. Industrial, the strength of the adhesive for low surface energy applications, wider temperature range, and longer weathering applications is also increasing, so silicone-based adhesives may be required. However, many silicone binders are not strong interact (e.g., adhesion), which may cause silicone binders and backing layers, objects to be adhered. L...
