摘要： A reticulated thermoplastic film includes a backing with openings and discrete elements protruding from the first major surface. There are two discrete elements aligned in a first direction abutting opposite ends of any given opening. In a second direction perpendicular to the first direction, there is one discrete element between the given opening and an adjacent opening aligned in the second direction. Each portion of the backing around the given opening is plastically deformed in its lengthwise direction and typically has higher stretch-induced molecular orientation at its edge adjacent the given opening than at its midpoint. The openings are often retractable. A method of making a reticulated thermoplastic film is also disclosed. The method includes stretching a thermoplastic backing with a plurality of discrete elements in the first direction. Subsequently stretching the backing in the second direction forms a tear in the backing between two adjacent discrete elements.

摘要： A method for manufacturing a phase difference film having specific optical properties from a pre-stretch film that includes a resin layer (a) made of a resin A containing polycarbonate and a resin layer (b) made of a resin B having a negative intrinsic birefringence, wherein the pre-stretch film has a property of exhibiting a phase difference that varies depending on temperatures. The method includes a stretching step of performing uniaxial stretching two or more times at different temperatures and in different directions, so that a resin layer having a specific plane orientation coefficient is obtained by stretching the resin layer (a), and a resin layer having specific birefringence and specific Nz coefficient is obtained by stretching the resin layer (b). The resin A has a specific glass transition temperature TgA, and the TgA and a glass transition temperature TgB of the resin B satisfy a specific relationship.
