    摘要: An ultraviolet curing antifogging agent is disclosed. The composition includes block copolymer (a) having a hydrophilic polymer segment (a1) and a hydrophobic polymer segment (a2). A polar solvent (c) is provided in which the hydrophilic polymer segment (a1) can easily be dissolved while the hydrophobic polymer segment (a2) can not. It further includes a photopolymerizable compound (b), and a photopolymerization initiator (d). The block copolymer (a) contains at least one hydrophilic monomer selected from the group of: a (meth) acrylamide compound represented by the general formula: CH.sub.2 .dbd.CR.sub.1 CONR.sub.2 R.sub.3 ; a cyclic (meth)acrylamide compound represented by the general formula ##STR1## and a hydroxyalkyl (meth)acrylate. Further, the hydrophilic polymer segment (a1) is formed by a radically polymerizable monomer having a functional group such as glycidyl group. The hydrophobic polymer segment (a2) is formed by a radically polymerizable monomer and a hydrophobic monomer which is copolymerizable with the former radically polymerizable monomer. The weight ratio of the hydrophilic polymer segment (a1) to the hydrophobic polymer segment (a2) is 50/50 to 95/5. The photopolymerizable compound (b) can be represented by the general formula CH.sub.2 .dbd.CR.sub.1 COO(CH.sub.2 CR.sub.4 HO).sub.n OCCR.sub.1 .dbd.CH.sub.2. The weight ratio of the component (a) to the component (b) is in the range of 10/90 to 90/10 in terms of the solid content. Such compositions have excellent antifogging properties and can be applied to transparent plastic materials to prevent fogging.
