PROTECTIVE FILM-LAMINATED ADHESIVE SHEET

摘要

Protective film-laminated adhesive sheets which include; an adhesive sheet including a support having first and second surfaces and a resin composition layer in contact with the second surface of the support; and a protective film having first and second surfaces with the second surface of the protective film in contact with the resin composition layer of the adhesive sheet and in which the first surface of the protective film has an arithmetic mean roughness (Rap1) of 100 nm or more, and the second surface of the protective film has an arithmetic mean roughness (Rap2) of 100 nm or more are capable of suppressing a winding displacement when the sheet is wound into a roll and are capable of preventing a resin separation when the protective film is peeled off in an automatic cutter device.

1. A protective film-laminated adhesive sheet comprising:
an adhesive sheet comprising a support having a first surface and a second surface, and a resin composition layer in contact with said second surface of said support; and a protective film having a first surface and a second surface, wherein said second surface of said protective film is in contact with said resin composition layer of said adhesive sheet, wherein said first surface of the protective film has an arithmetic mean roughness (Rap1) of 100 nm or more, wherein said arithmetic mean roughness (Rap1) is measured in conformity with Japanese Industrial Standard (JIS) B 0601, and said second surface of said protective film has an arithmetic mean roughness (Rap2) of 100 nm or more, wherein said arithmetic mean roughness (Rap2) is measured in conformity with JIS B 0601.
