Abstract
Abstract A water-dilutable lacquer based on an alkyd or acrylate resin containing carboxyl groups, which have been neutralized with an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen. The lacquers according to the invention are particularly suitable for use in the production of baked coatings on thermostable substrates, metal sheets, or shaped metal parts.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
43 words
A water-dilutable lacquer based on carboxyl group containing alkyd or acrylate resins, wherein the carboxyl groups have been neutralized with an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen and having a boiling point above 200° C. at normal pressure.
Claim 2
Dependent Claim
43 words
A water-dilutable lacquer based on carboxyl group containing alkyd or acrylate resins, wherein the carboxyl groups have been neutralized with an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen and having a boiling point above 200° C. at normal pressure.
Claim 3
Dependent Claim
26 words
The lacquer of claim 1 wherein the carboxyl groups have been neutralized with an amine containing from one to five 2,3-dihydroxy propyl groups per amine nitrogen.
Claim 4
Dependent Claim
45 words
The lacquer of claim 1 wherein the carboxyl groups have been neutralized with an amine containing from 1 to 4 amine nitrogen atoms per molecule and at least one 2,3-dihydroxy propyl group per amine nitrogen, and having a molecular weight of from 91 to 600.
Claim 5
Dependent Claim
40 words
The lacquer of claim 1 wherein the carboxyl groups have been neutralized with an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen which also contains alkyl groups or aryl groups having from 2 to 18 carbon atoms.
Claim 6
Dependent Claim
49 words
The lacquer of claim 1 wherein the carboxyl groups have been neutralized with an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen which also contains alkyl groups or aryl groups having from 2 to 18 carbon atoms and hydroxyl groups and/or ether groups in the molecule.
Claim 7
Dependent Claim
42 words
In a process for preparing water-dilutable lacquer systems from carboxyl group containing alkyd or acrylate resins by neutralizing the carboxyl groups, the improvement which comprises using as a neutralizing agent an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen.
Claim 8
Dependent Claim
42 words
In a process for preparing water-dilutable lacquer systems from carboxyl group containing alkyd or acrylate resins by neutralizing the carboxyl groups, the improvement which comprises using as a neutralizing agent an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen.
Claim 9
Dependent Claim
71 words
In a process of preparing a substrate with a lacquer film which comprises applying a water-dilutable lacquer coating to the substrate and then baking the thus coated substrate to obtain a baked resin coating, the improvement which comprises applying a water-dilutable lacquer based on carboxyl group containing alkyd or acrylate resins wherein the carboxyl groups have been neutralized with an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen.
Claim 10
Dependent Claim
71 words
In a process of preparing a substrate with a lacquer film which comprises applying a water-dilutable lacquer coating to the substrate and then baking the thus coated substrate to obtain a baked resin coating, the improvement which comprises applying a water-dilutable lacquer based on carboxyl group containing alkyd or acrylate resins wherein the carboxyl groups have been neutralized with an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen.
Claim 11
Dependent Claim
27 words
In a thermostable substrate having a lacquer film derived from a water-dilutable lacquer, the improvement which comprises deriving the film from the water-dilutable lacquer of claim 1.
