Composition of ultraviolet curing antifogging agent and process for forming antifogging coating film |
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: CH2=CR1CONR2R3; a cyclic (meth)acrylamide compound represented by the general formula <IMAGE> 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 CH2=CR1COO(CH2CR4HO)nOCCR1=CH2. 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.
