Document Type and Number:
WIPO Patent Application WO/2016/135997
Kind Code:
A1
Abstract:
Provided is a pressure-sensitive adhesive film for application to windows which is excellent in terms of water drainage during and after application with water and of tight adhesion. The pressure-sensitive adhesive film for application to windows includes a pressure-sensitive adhesive layer which comprises an acrylic block copolymer and a plasticizer and which has an indentation hardness of 3.0 N/mm2 or less. It is preferable that when the pressure-sensitive adhesive film for application to windows is applied to a glass surface using a water-based application liquid and then allowed to stand for 168 hours, then the water retention should be 4.0% or less. Preferably, the acrylic block copolymer has a hardness, as measured with durometer type A, of 50 or less.
