First claim

What is claimed is:

1. A composition, comprising:
a compound having a benzodithiol structure and a silane coupling group; and
a compound having an —O—Si—O— structure,
wherein the compound having the benzodithiol structure and the silane coupling group is a compound represented by General Formula (I) or General Formula (II):

in General Formula (I) or General Formula (II), R 1 and R 2 each independently represent a hydrogen atom, an alkyl group, an aryl group, an acyl group, or a carbamoyl group, R 3 and R 4 each independently represent a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an alkoxy group, or an aryloxy group, and W, X, Y, and Z each independently represent an electron withdrawing group; and W and X may be bonded to each other to form a ring, and Y and Z may be bonded to each other to form a ring; provided that R 1 , R 2 , R 3 , R 4 , W, X, Y, and Z may further have a substituent and at least one of R 1 , R 2 , R 3 , R 4 , W, X, Y, or Z contains the silane coupling group as a substituent,
wherein the silane coupling group is a trialkoxysilyl group, a dialkoxyalkylsilyl group, or an alkoxydialkylsilyl group,
wherein the compound having an —O—Si—O— structure as a hydrolyzable alkoxysilane is selected from the group consisting of tetramethoxysilane, tetraethoxysilane, tetra-n-propoxysilane, tetra-i-propoxysilane, tetra-n-butoxysilane, methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, n-propyltrimethoxysilane, n-propyltriethoxysilane, phenyltrimethoxysilane, phenyltriethoxysilane, γ-glycidyloxypropyltrimethoxysilane, γ-glycidyloxypropyltriethoxyslane, γ-glycidyloxypropylmethyldimethoxysilane, γ-glycidyloxypropylmethyldiethoxysilane, γ-methacryloyloxypropyltrimethoxysilane, γ-methacryloyloxypropyltriethoxysilane, γ-methacryloyloxypropylmethyldimethoxysilane, vinyltrimethoxysilane, vinyltriethoxysilane, 3,4-epoxycyclohexylethyltrimethoxysilane, 3,4-epoxycyclohexylethyltriethoxysilane, tris-(trimethoxysilylpropyl)isocyanurate, 4-trimethoxysilylstyrene, 3,3,3-trifluoropropyltrimethoxysilane, dimethyldimethoxysilane, dimethyldiethoxysilane, diethyldimethoxysilane, diethyldiethoxysilane, di-n-propyldimethoxysilane, di-n-propyldiethoxysilane, diphenyldimethoxysilane, divinyldiethoxysilane, bis(triethoxysilylpropyl)tetrasulfide, 3-(trimethoxysilyl)propylisocyanate, and 3-(triethoxysilyl)propylisocyanate.

2. The composition according to claim 1 , wherein, in General Formula (I) or General Formula (II), at least one of R 1 or R 2 is a hydrogen atom.

3. The composition according to claim 1 , wherein, in General Formula (I) or General Formula (II), at least one of R 1 or R 2 is a carbamoyl group or an alkyl group, and R 3 and R 4 are hydrogen atoms.

4. The composition according to claim 1 , wherein the silane coupling group is the trialkoxysilyl group.

5. A film having a polysiloxane structure and formed from the composition according to claim 1 .

6. A glass article, comprising:
a glass substrate; and
the composition according to claim 1 positioned on at least a part of the glass substrate.
