<P>PROBLEM TO BE SOLVED: To provide a photocurable resin composition which has high hardness, is excellent in transparency, antistaticity, storage stability and adhesivity to a substrate in wet heat condition, is suppressed in interference fringes (rainbow unevenness) under a three-wavelength fluorescent lamp, and does not cause whitening irrelevant to the transportation speed of a coating line in curing with light irradiation; and to provide an article having its cured film, and a method for producing the same. <P>SOLUTION: The photocurable resin composition comprises (1) an inorganic oxide microparticle of ≤80 nm in average particle diameter, (2) a compound having ≥3 (meth)acrylic groups, (3) a compound having 1 or 2 (meth)acrylic groups, (4) an ionic compound represented by R<SP POS="POST">1</SP>R<SP POS="POST">2</SP>R<SP POS="POST">3</SP>R<SP POS="POST">4</SP>N<SP POS="POST">+</SP>X<SP POS="POST">-</SP>(R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>, R<SP POS="POST">3</SP>and R<SP POS="POST">4</SP>are a group selected from CH<SB POS="POST">3</SB>, C<SB POS="POST">2</SB>H<SB POS="POST">5</SB>, C<SB POS="POST">2</SB>H<SB POS="POST">4</SB>OCH<SB POS="POST">3</SB>, C<SB POS="POST">6</SB>H<SB POS="POST">13</SB>and C<SB POS="POST">8</SB>H<SB POS="POST">17</SB>, and X is a group selected from N(SO<SB POS="POST">2</SB>CF<SB POS="POST">3</SB>)<SB POS="POST">2</SB>, BF<SB POS="POST">4</SB>and PF<SB POS="POST">6</SB>), (5) an ionic compound represented by Li<SP POS="POST">+</SP>Y<SP POS="POST">-</SP>(Y is a group selected from ClO<SB POS="POST">4</SB>, SO<SB POS="POST">2</SB>CF<SB POS="POST">3</SB>, SO<SB POS="POST">2</SB>C<SB POS="POST">2</SB>F<SB POS="POST">5</SB>, N(SO<SB POS="POST">2</SB>CF<SB POS="POST">3</SB>)<SB POS="POST">2</SB>, N(SO<SB POS="POST">2</SB>C<SB POS="POST">2</SB>F<SB POS="POST">5</SB>)<SB POS="POST">2</SB>, BF<SB POS="POST">4</SB>and PF<SB POS="POST">6</SB>), (6) a radical photopolymerization initiator, and (7) a fluorene derivative containing a (meth)acrylic group. The photocurable resin composition exhibits a synergetic effect of the inorganic oxide microparticle and the ionic compound to thereby contribute to both antistaticity and dispersion stability. <P>COPYRIGHT: (C)2012,JPO&INPIT |
