Provided is a method for producing a metal-clad laminate of a thermoplastic liquid crystal polymer film (TLCP film) and a metal sheet(s) bonded to at least one surface of the film using roll-to-roll processing. The metal sheet has a surface with a ten-point average roughness (Rz) of 5.0 m or less to be bonded to the TLCP film. The method includes preparing the laminate, dry-treating the laminate by subjecting the laminate passed through a dry zone satisfying the following conditions (1) and (2): (1) a drying temperature of lower than the melting point of the TLCP film, (2) for a drying period of 10 seconds or longer, and heat-treating the dried laminate by subjecting the laminate passed through a heating zone on a temperature condition of not lower than the melting point of the TLCP film successively after the dry treatment.

The present specification provides a multi-layer liquid crystal film including: a substrate; a first alignment film provided on the substrate; a first liquid crystal film provided on the first alignment film; a second alignment film provided on the first liquid crystal film and comprising a multifunctional acrylate; and a second liquid crystal film provided on the second alignment film, and a method for manufacturing a polarizing plate, including: laminating the multi-layer liquid crystal film to a polarizer, and peeling off the substrate.

Soft-imprint alignment processes for patterning liquid crystal polymer layers via contact with a reusable alignment template are described herein. An example soft-imprint alignment process includes contacting a liquid crystal polymer layer with a reusable alignment template that has a desired surface alignment pattern such that the liquid crystal molecules of the liquid crystal polymer are aligned to the surface alignment pattern via chemical, steric, or other intermolecular interaction. The patterned liquid crystal polymer layer may then be polymerized and separated from the reusable alignment template. The process can be repeated many times. The reusable alignment template may include a photo-alignment layer that does not comprise surface relief structures that correspond to the surface alignment pattern and a release layer above this photo-alignment layer. A reusable alignment template and methods of fabricating the same are also disclosed.

This laminate includes a thermoplastic resin layer and a protective layer, the protective layer including a welding layer, and the welding layer including a thermoplastic elastomer.
