▎ 摘　　要

NOVELTY - Biaxially oriented polyester release liner film comprises uniform micro textured surface for preparing an article backed with pressure sensitive adhesive, where the liner comprises layer of biaxially oriented polyester film having release side with micro textured surface, the texture support layer is biaxially oriented layer and is part of biaxially oriented polyester film and not added layer of unlike polymers, and back side, and release material is bonded with the texture support layer, where the texture created in the texture support layer is dimensioned to form fluid egress channels in the bonding surface of the pressure sensitive adhesive, when the textured release surface is forced into the bonding surface of the pressure sensitive adhesive coated article, such that the fluid egress channels defines textured bonding surface having exit pathways for at least some of the fluid to egress from behind the article when the article is adhered to a substrate. USE - The film is useful as: protective films ex. as a surface protection through external contamination like dust or electrostatic charge for electronic articles; functional films ex. Graphene films; articles containing decorative color or images ex. Advertising boards etc; paint on the body of a vehicle ex. Auto-mobile, aircraft, watercraft etc; equipments, appliances, architecture or any other even or uneven surface substrate. ADVANTAGE - The film is easy to process, stable, has a thin release liner, has sufficient structural integrity, can be easily removed from the pressure sensitive adhesive in one piece. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) making (M1) a textured biaxially oriented polyester release liner for use with an article backed with a pressure sensitive adhesive, comprising providing layer of polyester film having a release side with a micro textured surface, the texture support layer is a biaxially oriented layer and is a part of biaxially oriented polyester film and not an added layer of unlike polymers, and a back side, and a release material is bonded with the texture support layer, where the texture created in the texture support layer is dimensioned to form fluid egress channels in the bonding surface of the pressure sensitive adhesive, when the textured release surface is forced into the bonding surface of the pressure sensitive adhesive coated article, such that the fluid egress channels defines a textured bonding surface having exit pathways for at least some of the fluid to egress from behind the article when the article is adhered to a substrate, and providing a release material on the release side of the liner, either before or after forming of the textured release surface; (2) adhesive backed article assembly in combination with release liner and pressure sensitive adhesive, where the release liner is biaxially oriented polyester release liner and the texture formed in the biaxially oriented polyester release liner is applied in the adhesive to form a textured bonding surface on the adhesive with fluid egress channels that define exit pathways for fluid to egress from behind the article when textured bonding surface is disposed on a substrate; and (3) making (M2) adhesive backed article assembly comprising providing textured biaxially oriented polyester release liner, providing pressure sensitive adhesive, bringing together the pressure sensitive adhesive and the textured release surface of biaxially oriented polyester release liner so as to form fluid egress channels in the pressure sensitive adhesive, bonding together the pressure sensitive adhesive and the back of an article to form an adhesive backed article, and forming the adhesive backed article assembly by either performing bonding together and then bringing together, where the fluid egress channels at least partially define a structural bonding surface of the adhesive backed article having egress channels for fluid to egress from behind the article when textured bonding surface is disposed on a substrate.
