摘要:
The present invention relates to a cellulose acylate film having a high modulus of elasticity and a high surface hardness. The cellulose acylate film of the present invention is characterized by containing 1 vol % to 99 vol % of a metal oxide having an average particle size of 1 nm to 400 nm. The metal oxide used here is preferably a metal oxide having a Mohs hardness of at least 7, and specific examples thereof include aluminum oxide and silicon dioxide. This metal oxide may be subjected to a surface treatment. Furthermore, a functional thin film such as a hardcoat layer may be formed on the cellulose acylate film containing the metal oxide.
摘要:
A curable composition that is curable by polymerizing both a group capable of ring-opening polymerization and an ethylenically unsaturated group includes a cross-linkable polymer containing a repeating unit represented by the formula below, the group capable of ring-opening polymerization being present in a side chain of the polymer. A hardcoated article is formed by curing the curable composition. Its hardcoat layer has a pencil hardness of 4H to 9H. A hardcoated film is formed by coating on a plastic film the curable composition and curing it. The hardcoated film is used, for example, to laminate the front face of an image display device. In the formula, R1 denotes hydrogen or an alkyl group having 1 to 4 carbon atoms, P1 is a monovalent group containing a group capable of ring-opening polymerization, and L1 is a single bond or a divalent linking group.
