Optical member with hard coat layer-forming composition

Abstract

An optical member, having: a plastic base; and a hard coat layer produced from a hard coat layer-forming composition and disposed on the plastic base, wherein the hard coat layer-forming composition includes: metal oxide particles; a component X that is at least one selected from the group consisting of an organic silicon compound represented by a Formula (1): (RA-LA)n-Si—(X)4-n Formula (1); and a component Y that is at least one selected from the group consisting of an organic silicon compound represented by a Formula (2): (RB-LB)m-Si—(X)4-m Formula (2).

1 . An optical member, comprising:
 a plastic base; and   a hard coat layer produced from a hard coat layer-forming composition and disposed on the plastic base, wherein the hard coat layer-forming composition comprises: metal oxide particles;   a component X that is at least one selected from the group consisting of an organic silicon compound represented by Formula (1):
   (R A -L A ) n -Si—(X) 4-n   Formula (1)
 
   
       (where RA denotes an epoxy group; L A  denotes an alkylene group that has 5 or less total carbon atoms and that optionally includes a heteroatom; X denotes a hydrolyzable group; and n denotes an integer of 1 to 3], a hydrolysate thereof and a hydrolyzed condensate thereof; and
 a component Y that is at least one selected from the group consisting of an organic silicon compound represented by Formula (2):
   (R B -L B ) m -Si—(X) 4-m   Formula (2)
 
 
 
       [where R B  denotes an epoxy group; L B  denotes an alkylene group that has 6 or more total carbon atoms and that optionally includes a heteroatom; X denotes a hydrolyzable group; and m denotes an integer of 1 to 3], a hydrolysate thereof and a hydrolyzed condensate thereof. 
     
     
         2 . The optical member according to  claim 1 ,
 wherein a content of the component Y is not less than 5 mol % and not more than 25 mol % with respect to a total molar quantity of the component X and the component Y.   
     
     
         3 . The optical member according to  claim 1 ,
 wherein the metal oxide particles comprise particles formed from at least one selected from the group consisting of titanium oxide, tin oxide, zirconium oxide and a composite oxide thereof.   
     
     
         4 . The optical member according to  claim 1 ,
 wherein a content of the metal oxide particles is 10 to 20 vol % with respect to a volume of total solids of the hard coat layer-forming composition.
