Abstract
An anti-reflection film that is an optical film, at least has a hard coat layer, and a low-refractive-index layer containing a binder polymer, on a transparent support, wherein said hard coat layer and/or said low-refractive-index layer contains: (a) a hydrolysate of an organosilane in which a hydroxyl group or a hydrolysable group is directly bonded to silicon, and/or a partial condensation product thereof; and (b) at least one metal chelate compound of an alkylalcohol, and a compound of R4COCH2COR5, in which R4 is an alkyl group, and R5 is an alkyl or alkoxy group, as ligands, and a metal selected from Zr, Ti and Al, as a central metal.
Claims20
An anti-reflection film that is an optical film, comprising, at least, a hard coat layer, and a low-refractive-index layer containing a binder polymer, on a transparent support, wherein said hard coat layer and/or said low-refractive-index layer contains:
- (a) a hydrolysate of an organosilane in which a hydroxyl group or a hydrolysable group is directly bonded to silicon, and/or a partial condensation product thereof;
- and
- (b) at least one metal chelate compound of an alcohol represented by formula R3OH, in which R3 represents an alkyl group having 1 to 10 carbon atoms, and a compound represented by formula R4COCH2COR5, in which R4 represents an alkyl group having 1 to 10 carbon atoms, and R5 represents an alkyl group having 1 to 10 carbon atoms or an alkoxy group having 1 to 10 carbon atoms, as ligands, and a metal selected from the group consisting of Zr, Ti and Al, as a central metal.
A hardening composition, comprising:
- a hydrolysate of an organosilane represented by formula (1), which is produced in the presence of an acid catalyst, and/or a partial condensation product thereof:
- (R10)m—Si(X)4-m Formula (1)
- wherein, in formula (1), R10 represents a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group;
- x represents a hydroxyl group or a hydrolysable group;
- and m represents an integer of 1 to 3, wherein a component having a molecular weight of 1,000 to 20,000 accounts for 80% by mass or more of components having a molecular weight of 300 or more among the hydrolysate of said organosilane and/or the partial condensation product thereof.
