Abstract: A laminate and a method for producing a patterned substrate using the same are disclosed herein. In some embodiments, a laminate includes a substrate, and a stripe pattern having first and second polymer lines alternately and repeatedly disposed on the substrate, wherein the first polymer line comprises a first polymer having a first polymerized unit having a ring structure connected to a main chain and a second polymerized unit represented by Formula 1. The method may be applied to manufacture of devices, such as electronic devices, or of applications, such as integrated optical systems, guidance and detection patterns of magnetic domain memories, flat panel displays, liquid crystal displays (LCDs), thin film magnetic heads or organic light emitting diodes, and may be used to build a pattern on a surface used in manufacture of discrete track media, such as integrated circuits, bit-patterned media and/or magnetic storage devices such as hard drives.
