<P>PROBLEM TO BE SOLVED: To provide an antireflective laminate such as an antireflective film having essentially each layer of a transparent substrate, a hard coat layer and a low-refractive index layer, which is imparted with a flatness of the hard coat layer and is excellent in transparency and membrane strength. <P>SOLUTION: The antireflective laminate comprises at least two layers having a light-transmitting hard coat layer as one of constitutional layers. The hard coat layer is a hardened layer having a block copolymer as a surface leveling agent fixed in the vicinity of the surface in a hard coat layer formed by a binder constituent. The block copolymer is an AB-type block copolymer comprising a block (A) composed of a radical-polymerizing monomer as a polymerizing constituent and a block (B) composed of a polymerizing constituent including a silicon element and/or a fluorine element. A molecular weight distribution of the block copolymer determined by a GPC method is in the range of 1-2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
