Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
A water-dilutable binder for lacquers and paints based on synthetic resins, consisting essentially of a resin which is selected from the group consisting of alkyd, polyester and modified alkyd and which is soluble in organic solvents and which has an acid number of between 5 and 30 mg KOH/g, water forming with the resin a colloidal, thermo-dynamically stable solution in the form of a microemulsion, and at least one emulsifier having a hydrophile-lipophile balance such that the solubilizing power of the solution is such that the microemulsion forms spontaneously with a dispersed phase having a particle size less than 0.1 μ.
Claim 2
Dependent Claim
101 words
A water-dilutable binder for lacquers and paints based on synthetic resins, consisting essentially of a resin which is selected from the group consisting of alkyd, polyester and modified alkyd and which is soluble in organic solvents and which has an acid number of between 5 and 30 mg KOH/g, water forming with the resin a colloidal, thermo-dynamically stable solution in the form of a microemulsion, and at least one emulsifier having a hydrophile-lipophile balance such that the solubilizing power of the solution is such that the microemulsion forms spontaneously with a dispersed phase having a particle size less than 0.1 μ.
Claim 3
Dependent Claim
24 words
A binder according to claim 1, characterized in that the emulsifier is of the anionic, cationic, amphoteric or non-ionic type or a mixture thereof.
Claim 4
Dependent Claim
25 words
A binder according to claim 2, characterized in that the emulsifier is an amine- or ammonium salt of a medium carbon chain length fatty acid.
Claim 5
Dependent Claim
20 words
A binder according to claim 3, characterized in that the emulsifier is an ammonium- or diethanolamine salt of capric acid.
Claim 6
Dependent Claim
32 words
A binder according to claim 2, characterized in that the emulsifier is an alkyl- or alkylphenylpolyglycol ether and that the free acidic groups of the resin have been neutralized with a base.
Claim 7
Dependent Claim
28 words
A binder according to claim 2, characterized in that the emulsifier is a nonylphenylpolyglycol ether having 6-12 ethyleneoxide groups and that the base consists of an organic amine.
Claim 8
Dependent Claim
27 words
A binder according to claim 2, characterized in that the emulsifier is a nonylphenylpolyglycol ether having 8-12 ethyleneoxide groups and that the base consists of a diethanolamine.
