Abstract

Provided is a composition for forming a protective film for a transparent conductive film, said composition comprising a triazine ring-containing hyperbranched polymer comprising a repeating unit structure represented by formula (1) and a crosslinking agent having a molecular weight of 1,000 or greater.

In formula (1): R and R′ independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aralkyl group; and Ar represents a definite aromatic ring-containing group.

First claim

1 . A film-forming composition for use on a transparent conductive film, the composition being characterized by comprising a triazine ring-containing hyperbranched polymer which includes a recurring unit structure of formula (1) below

(wherein R and R′ are each independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aralkyl group; and
Ar is at least one moiety selected from the group consisting of moieties of formulas (2) to (13) below

(in which R 1 to R 92 are each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfo group, an alkyl group of 1 to 10 carbon atoms, or an alkoxy group of 1 to 10 carbon atoms;
R 93 and R 94 are hydrogen atoms or alkyl groups of 1 to 10 carbon atoms;
W 1 and W 2 are each independently a single bond, —C(R 95 )(R 96 )— (R 95 and R 96 being each independently a hydrogen atom or an alkyl group of 1 to 10 carbon atoms, with the proviso that when R 95 and R 96 are both alkyl groups, they may mutually bond to form, together with the carbon atom to which they are bonded, a ring), —C(O)—, —O—, —S—, —S(O)—, —S(O) 2 — or —N(R) 97 — (R 97 being a hydrogen atom or an alkyl group of 1 to 10 carbon atoms); and
X 1 and X 2 are each independently a single bond, an alkylene group of 1 to 10 carbon atoms, or a group of formula (14) below

(R 98 to R 101 being each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfo group, an alkyl group of 1 to 10 carbon atoms, or an alkoxy group of 1 to 10 carbon atoms; and
Y 1 and Y 2 being each independently a single bond or an alkylene group of 1 to 10 carbon atoms))), and a crosslinking agent A having a molecular weight of at least 1,000.

2 . The composition of claim 1 , wherein crosslinking agent A is a poly(meth)acrylic compound.

3 . The composition of claim 1 or 2 which includes from 0.1 to 30 parts by weight of crosslinking agent A per 100 parts by weight of the triazine ring-containing hyperbranched polymer.

4 . The composition of claim 1 which further comprises a crosslinking agent B having a molecular weight of less than 1,000.

5 . The composition of claim 4 , wherein crosslinking agent B is a poly(meth)acrylic compound.

6 . The composition of claim 4 or 5 which includes from 0.5 to 400 parts by weight of crosslinking agent B per 100 parts by weight of crosslinking agent A.

7 . The composition of claim 1 which further comprises a solvent.

8 . A protective film for use on a transparent conductive film, which protective film is obtained by curing the composition of claim 1 .

9 . The protective film of claim 8 , wherein the transparent conductive film is a transparent conductive film having electrically conductive nanostructures.

10 . The protective film of claim 9 , wherein the electrically conductive nanostructures are made of silver nanowire.

11 . A transparent electrode comprising a transparent conductive film and the protective film of claim 8 formed on the transparent conductive film.

12 . An electronic device comprising a transparent conductive film and the protective film of claim 8 formed on the transparent conductive film.

13 . The electronic device of claim 12 which is an organic electroluminescence display.
