Abstract

Official abstract text for this publication.

Provided are an ultraviolet absorbing agent represented by General Formula (1) and an application thereof. In General Formula (1), R11 represents a monovalent substituent. n is 1 or 2. W1 and W2 each independently represent a hydrogen atom, a cyano group, a carbamoyl group, a sulfamoyl group, a nitro group, an acyl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an alkyl group, an aryl group, or a heterocyclic group, where at least one of W1 or W2 represents a substituent having a Hammett's substituent constant σp value of 0.2 or more. W1 and W2 may be bonded to each other to form a ring.

First claim

Opening claim text (preview).

What is claimed is: 1 . An ultraviolet absorbing agent represented by General Formula (1), wherein, in General Formula (1), R 11 represents a monovalent substituent, n is 1 or 2, where in a case where n is 2, two existing R 11 's may be the same or different from each other, W 1 and W 2 each independently represent a hydrogen atom, a cyano group, a carbamoyl group, a sulfamoyl group, a nitro group, an acyl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an alkyl group, an aryl group, or a heterocyclic group, where at least one of W 1 or W 2 represents a substituent having a Hammett's substituent constant σp value of 0.2 or more, and W 1 and W 2 may be bonded to each other to form a ring, and at least one group of R 11 , W 1 , or W 2 has an acid group selected from the group consisting of a sulfonic acid group, a carboxylic acid group, and a phosphoric acid group. 2 . The ultraviolet absorbing agent according to claim 1 , wherein the ultraviolet absorbing agent is represented by General Formula (2), wherein, in General Formula (2), R 1 and R 2 each independently represent a monovalent substituent, W 1 and W 2 each independently represent a hydrogen atom, a cyano group, a carbamoyl group, a sulfamoyl group, a nitro group, an acyl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an alkyl group, an aryl group, or a heterocyclic group, where at least one of W 1 or W 2 represents a substituent having a Hammett's substituent constant σp value of 0.2 or more, and W 1 and W 2 may be bonded to each other to form a ring, and at least one group of R 1 , R 2 , W′, or W 2 has an acid group selected from the group consisting of a sulfonic acid group, a carboxylic acid group, and a phosphoric acid group. 3 . The ultraviolet absorbing agent according to claim 1 , wherein the ultraviolet absorbing agent is represented by General Formula (3), wherein, in General Formula (3), R 1 and R 2 each independently represent a monovalent substituent, R 3 represents an alkyl group, an aryl group, or a heterocyclic group, and at least one group of R 1 , R 2 , or R 3 has an acid group selected from the group consisting of a sulfonic acid group, a carboxylic acid group, and a phosphoric acid group. 4 . The ultraviolet absorbing agent according to claim 1 , wherein the acid group is a sulfonic acid group. 5 . The ultraviolet absorbing agent according to claim 1 , wherein a solubility in water at 25° C. is 1% by mass or more. 6 . An ultraviolet absorbing composition comprising: the ultraviolet absorbing agent according to claim 1 ; and an aqueous medium. 7 . The ultraviolet absorbing composition according to claim 6 , further comprising: a water-soluble polymer. 8 . An ultraviolet absorbing film, wherein the ultraviolet absorbing film is a cured substance of the ultraviolet absorbing composition according to claim 6 . 9 . A laminate comprising: a base material; and the ultraviolet absorbing film according to claim 8 , formed on the base material. 10 . A compound represented by General Formula (4), wherein, in General Formula (4), L 1 and L 2 each independently represent an alkylene group, X's each independently represent a hydrogen atom or a countercation of —SO 3 − , and W 1 and W 2 each independently represent a hydrogen atom, a cyano group, a carbamoyl group, a sulfamoyl group, a nitro group, an acyl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an alkyl group, an aryl group, or a heterocyclic group, where at least one of W 1 or W 2 represents a substituent having a Hammett's substituent constant σp value of 0.2 or more, and W 1 and W 2 may be bonded to each other to form a ring.
