1-25. (canceled)
A binder for air drying paint, based on metal oxide-containing nanoparticles with unsaturated organic branches, the binder comprising:
- at least one metal atom of the nanoparticle chemically bound to an organic branch with at least an unsaturated ethylenic functionality,
- wherein the binder includes the following chemical substructure:
- O1.5Si—(CH2)p—NH—C(O)—(CH2)q—(CH═CH)x—(CH2)r—(CH═CH—CH2)y—(CH2)s—(CH═CH)z—(CH2)t—CH3
- where
- p is an integer from 1 to 24
- q, r, s, and t are each an integer from 0 to 21
- x and z are each an integer from 0 to 4 and
- y is an integer from 0 to 6
- and wherein oxygen atoms of the O15Si-are bound to metal atoms.

A process for preparation of a binder, the process comprising:
- preparing a polybranched organic/inorganic hybrid polymer when hydrolyzable metal compounds with functional amine groups are converted through hydrolysis and condensation;
- and
- reacting at least one of said functional amine groups with at least one unsaturated organic compound so that a covalent chemical bond or ionic bond is formed, between the N-atom of the functional amine group and at least one atom of the unsaturated organic compound.
An air drying paint or lacquer, comprising:
- at least one binder comprising
- at least one metal atom of the nanoparticle chemically bound to an organic branch with at least an unsaturated ethylenic functionality,
- wherein the binder includes the following chemical substructure:
- O1.5Si—(CH2)p—NH—C(O)—(CH2)q—(CH═CH)x—(CH2)r—(CH═CH—CH2)y—(CH2)s—(CH═CH)z—(CH2)t—CH3
- where
- p is an integer from 1 to 24
- q, r, s, and t are each an integer from 0 to 21
- x and z are each an integer from 0 to 4 and
- y is an integer from 0 to 6
- and wherein oxygen atoms of the O1.5Si— are bound to metal atoms.
