Abstract
Official abstract text for this publication.
The present invention relates to metal oxide precursors comprising i) at least one metal atom selected from the group consisting of In, Ga, Zn and Sn, ii) at least one non-photocrosslinkable ligand and iii) at least one photocrosslinkable ligand, to liquid coating compositions comprising the precursors, and to their use.
First claim
Opening claim text (preview).
1 . Metal oxide precursor comprising i) at least one metal atom selected from the group consisting of In, Ga, Zn and Sn, ii) at least one non-photocrosslinkable ligand and iii) at least one photocrosslinkable ligand. 2 . Precursor according to claim 1 , characterized in that the at least one non-photocrosslinkable ligand is selected from the group of radicals consisting of oxo radicals, hydroxyl radicals, alkoxy radicals, nitrate radicals and halide radicals. 3 . Precursor according to claim 2 , characterized in that it comprises as at least one non-photocrosslinkable ligand at least one oxo radical and at least one alkoxy radical. 4 . Precursor according to claim 1 , characterized in that it has as non-photocrosslinkable ligands exclusively oxo radicals, alkoxy radicals and radicals selected from the group consisting of nitrate radicals and halide radicals. 5 . Precursor according to claim 1 , characterized in that the at least one photocrosslinkable ligand is selected from the group of radicals consisting of acrylate radicals, methacrylate radicals and allyl radicals. 6 . Precursor according to claim 1 , characterized in that the at least one atom is In. 7 . Precursor according to claim 1 , characterized in that it has the generic formula [In 6 (μ 6 —O)(μ 2 —OR) 12-x Cl 6 (R′) x ] 2− with R=C 1-10 alkyl, R′=acrylate or methacrylate and x=1-10. 8 . Precursor according to claim 1 , characterized in that it has the generic formula [In 6 (μ 6 —O)(μ 2 —OR) 12-x (NO 3 ) 6 (R′) x ] 2− with R=C 1-10 alkyl, R′=acrylate or methacrylate and x=1-10. 9 . Liquid coating composition comprising a. at least one precursor according to claim 1 and b. at least one solvent. 10 . Coating composition according to claim 9 , characterized in that it further comprises at least one photoinitiator. 11 . Coating composition according to claim 10 , characterized in that the photoinitiator is phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide. 12 . Use of a precursor according to claim 1 for producing structured metal-oxidic layers.
