Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
A masonry paint composition containing an aqueous dispersion of (a) an organopolysiloxane of the formula ##STR3## where R is a hydrocarbon radical having from 1 to 18 carbon atoms which may be substituted by amine or halogen radicals and the hydrocarbon chain may be interrupted by amino groups or oxygen atoms, R' is selected from the group consisting of hydrogen atoms and alkyl radicals having from 1 to 3 carbon atoms, m is a number having an average of from 0 to 0.5, n is a number having an average of from 0.5 to 2.2 and the sum of m and n should not exceed 3, and (b) an organic polymer which does not exceed the weight of the organopolysiloxane (a), in which the organic polymer (b) is an ethylene-vinyl chloride copolymer.
Claim 2
Dependent Claim
132 words
A masonry paint composition containing an aqueous dispersion of (a) an organopolysiloxane of the formula ##STR3## where R is a hydrocarbon radical having from 1 to 18 carbon atoms which may be substituted by amine or halogen radicals and the hydrocarbon chain may be interrupted by amino groups or oxygen atoms, R' is selected from the group consisting of hydrogen atoms and alkyl radicals having from 1 to 3 carbon atoms, m is a number having an average of from 0 to 0.5, n is a number having an average of from 0.5 to 2.2 and the sum of m and n should not exceed 3, and (b) an organic polymer which does not exceed the weight of the organopolysiloxane (a), in which the organic polymer (b) is an ethylene-vinyl chloride copolymer.
Claim 3
Dependent Claim
85 words
The paint composition of claim 1, wherein the organopolysiloxane (a) is a mixture containing at least one silicone resin of the formula R"SiO.sub.3/2, (II) where R" is a hydrocarbon radical having from 1 to 10 carbon atoms and at least one polydiorganosiloxane of the formula ##STR4## where R"' is a radical selected from the group consisting of an amino and an aminoalkyl substituted alkyl radical having a total of from 1 to 10 carbon atoms and x is an integer having an average of 60.
Claim 4
Dependent Claim
70 words
The paint composition of claim 1, wherein the ethylene-vinyl chloride copolymer (b) contains from 1 to 50 percent by weight of ethylene and from 99 to 1 percent by weight of at least one other monomer, in which the other monomer consists of from 60 to 100 percent by weight of vinyl chloride and from 40 to 0 percent by weight of a monomer other than ethylene and vinyl chloride.
Claim 5
Dependent Claim
70 words
The paint composition of claim 2, wherein the ethylene-vinyl chloride copolymer (b) contains from 1 to 50 percent by weight of ethylene and from 99 to 1 percent by weight of at least one other monomer, in which the other monomer consists of from 60 to 100 percent by weight of vinyl chloride and from 40 to 0 percent by weight of a monomer other than ethylene and vinyl chloride.
Claim 6
Dependent Claim
18 words
The paint composition of claim 1, which contains a pigment (c) in addition to components (a) and (b).
Claim 7
Dependent Claim
18 words
The paint composition of claim 2, which contains a pigment (c) in addition to components (a) and (b).
Claim 8
Dependent Claim
18 words
The paint composition of claim 3, which contains a pigment (c) in addition to components (a) and (b).
Claim 9
Dependent Claim
18 words
The paint composition of claim 4, which contains a pigment (c) in addition to components (a) and (b).
Claim 10
Dependent Claim
50 words
The paint composition of claims 1, 2, 3, 4, 5, 6, 7 or 8, which contains less than 0.1 percent by weight of alkali metal salts of silicic acid or of methyl silicic acid, based on the sum of the weight of the organopolysiloxane (a) and ethylene-vinyl chloride copolymer (b).
