Claim 0:
1. A composition comprising at least one nanosized light emitting material and a (meth)acrylic polymer, wherein the (meth)acrylic polymer comprises at least one (meth)acrylic structural unit represented by the following chemical formula (1):, , in which:
R1 denotes, identically or differently at each occurrence, hydrogen, a straight-chain alkyl group having 1 to 20 C atoms, a branched or cyclic alkyl group having 3 to 20 C atoms, an alkenyl or alkynyl group having 2 to 20 C atoms, an aryl or heteroaryl group having 5 to 24 C atoms, where one or more non-adjacent methylene structural units (—CH2—) in said alkyl, alkenyl, alkynyl, aryl or heteroaryl groups may in each case be replaced by a sulfonyl group, a carbonyl group, an ether group, a sulfide group, a sulfoxide group, an ester group, an amide group or an imine group,
and wherein said alkyl, alkenyl, alkynyl, aryl or heteroaryl groups one or more H atoms may be replaced by F, Cl, Br, I, CN or OH, a carboxyl group (—COOH), a straight-chain alkyl or alkoxy group having 2 to 20 C atoms, a branched alkyl or alkoxy group having 3 to 20 C atoms, or an alkenyl or alkynyl group having 2 to 20 C atoms;

R2, R2′ denote, identically or differently at each occurrence, hydrogen, a hydroxyl group (—OH) a carboxyl group (—COOH), a straight-chain alkyl group having 1 to 20 C atoms, a branched or cyclic alkyl group having 3 to 20 C atoms, an alkenyl or alkynyl group having 2 to 20 C atoms, an aryl or heteroaryl group having 5 to 24 C atoms, where one or more non-adjacent methylene structural units (—CH2—) in said alkyl, alkenyl, alkynyl, aryl or heteroaryl groups may in each case be replaced by a sulfonyl group, a carbonyl group, an ether group, a sulfide group, a sulfoxide group, an ester group, an amide group or an imine group,
and wherein said alkyl, alkenyl, alkynyl, aryl or heteroaryl groups one or more H atoms may be replaced by F, Cl, Br, I, CN or OH, a carboxyl group (—COOH), a straight-chain alkyl or alkoxy group having 2 to 20 C atoms, a branched alkyl or alkoxy group having 3 to 20 C atoms, or an alkenyl or alkynyl group having 2 to 20 C atoms, with the proviso that both radicals R2 and R2′ bonded to the same C atom can denote carboxyl groups at the same time;

R3 denotes, identically or differently at each occurrence, hydrogen, a straight-chain alkyl group having 1 to 20 C atoms, a branched or cyclic alkyl group having 3 to 20 C atoms, an alkenyl or alkynyl group having 2 to 20 C atoms, an aryl or heteroaryl group having 5 to 24 C atoms, where one or more non-adjacent methylene structural units (—CH2—) in said alkyl, alkenyl, alkynyl, aryl or heteroaryl groups may in each case be replaced by a sulfonyl group, a carbonyl group, an ether group, a sulfide group, a sulfoxide group, an ester group, an amide group or an imine group,
and wherein said alkyl, alkenyl, alkynyl, aryl or heteroaryl groups one or more H atoms may be replaced by F, Cl, Br, I, CN or OH, a carboxyl group (—COOH), a straight-chain alkyl or alkoxy group having 2 to 20 C atoms, a branched alkyl or alkoxy group having 3 to 20 C atoms, or an alkenyl or alkynyl group having 2 to 20 C atoms;

R4 denotes, identically or differently at each occurrence, a straight-chain alkylene group having 1 to 20 C atoms, a branched alkylene group having 2 to 20 C atoms, an alkenylene or alkynylene group having 2 to 20 C atoms, or an arylene or heteroarylene group having 6 to 24 C atoms, where one or more methylene structural units (—CH2—) in said alkylene, alkenylene, alkynylene, arylene or heteroarylene groups may in each case be replaced by a sulfonyl group, a carbonyl group, an ether group, a sulfide group, a sulfoxide group, an ester group, an amide group, an imine group, a group CHR′ or a group CR′R″;
R′, R″ denote, identically or differently at each occurrence, a hydroxyl group, a straight-chain alkyl group having 1 to 20 C atoms, a branched or cyclic alkyl group having 3 to 20 C atoms, an alkenyl or alkynyl group having 2 to 20 C atoms, an aryl or heteroaryl group having 5 to 24 C atoms, where one or more non-adjacent methylene structural units (—CH2—) in said alkyl, alkenyl, alkynyl, aryl or heteroaryl groups may in each case be replaced by a sulfonyl group, a carbonyl group, an ether group, a sulfide group, a sulfoxide group, an ester group, an amide group or an imine group, and wherein said alkyl, alkenyl, alkynyl, aryl or heteroaryl groups one or more H atoms may be replaced by F, Cl, Br, I, CN or OH, a straight-chain alkyl or alkoxy group having 2 to 20 C atoms, a branched alkyl or alkoxy group having 3 to 20 C atoms, or an alkenyl or alkynyl group having 2 to 20 C atoms.
