Abstract

Provided is an additive for imparting ultraviolet absorbency, or an additive for imparting a high refractive index, which has satisfactory compatibility with a resin serving as a matrix and can maintain high transparency even if added in high concentrations. Also provided is an additive with which the function of imparting both ultraviolet absorbency and a high refractive index can be realized by means of one kind of additive. This additive is represented by the following Formula (I):

• • wherein at least one of R^1a to R^9a is a monovalent sulfur-containing group represented by the following Formula (i-1) or Formula (i-2):

R^10a_mSH  (i-1)

R^11a_nSR^12a—S_pR^13a  (i-2)

• • wherein R^10a to R^12a each represent a divalent hydrocarbon group or the like; and R^13a represents a monovalent hydrocarbon group or the like.

Claims

1-69. -69. (canceled)

70. An additive for imparting ultraviolet absorbency and/or a high refractive index to a matrix, the additive being represented by the following Formula (II):

71. The additive according to claim 70, wherein the monovalent sulfur-containing group is a group represented by Formula (ii-1), this monovalent sulfur-containing group represented by Formula (ii-1) is such that if q is 0, or if q is 1, R^11b includes an alkylene group having 12 or fewer carbon atoms, and

among the substituents for R^1b to R^10b other than the monovalent sulfur-containing group represented by Formula (ii-1), any one of the substituents is a hydroxyl group.

72. The additive according to claim 71, wherein among the substituents for R^1b to R^10b other than the monovalent sulfur-containing group represented by Formula (ii-1), any one of the substituents is a hydroxyl group, while the others are hydrogen atoms.

73. The additive according to claim 72, wherein the monovalent sulfur-containing group is a group represented by Formula (ii-2), this monovalent sulfur-containing group represented by Formula (ii-2) is such that R^12b and s units of R^13b each include an alkylene group having 18 or fewer carbon atoms, and

among the substituents for R^1b to R^10b other than the monovalent sulfur-containing group represented by Formula (ii-2), any one of the substituents is a hydroxyl group, while the others are hydrogen atoms.
